7D Crop & Tamron 17-50 VC [CR1]
August 30th, 2009 Posted in Canon 7D, Third Party Lenses
1.45x Crop for the 7D?
I was sent an email saying that the new 7D will be APS-C, but with a 1.45x crop factor. Apparently this is the limit so that EF-S lenses still work without vignetting.
First appeared on a DPR forum posting, I couldn’t find the link.
I have no confirmed source for this one.
Tamron 17-50 f/2.8 VC
Received word that someone bumped into a Tamron 17-50 f/2.8 VC (Vibration Correction) on Adorama’s web site. It was retailing for $749. The link has been removed from Adorama’s site.
Adorama give it up early?

Wow that’s unexpected. I’m with the group that wanted FF but 1.45x is bit better than 1.6x. Now I’m even more tempted to get it. Hope the price is right.

Pixel size at 1.45x and 18MP is equivalent to 14.7MP at 1.6x crop. Maybe they should just round it to 1.5x and admit that Nikon was right all along.

While the pixel density of 18mp on a 1.6 sensor seems unachievable, I highly doubt we’d see a 1.45x crop factor introduced. While this may work for Canon EF-S lenses (I don’t think it would) there’s no way other lens manufacturers like Sigma would have been building lenses that work on 1.45x crops.
Additionally even if some of the lenses didn’t vignette we’d still see way too many faults on the edges of the wide-angles.

Mmm, well considering Sigma and other 3rd party lens makers have to build for several mounts and Nikon’s mount is a 1.5 crop I don’t think a 1.45 crop will make that much difference; if anything it would affect Canon’s EF-S lenses more. There could be some sort of in-camera correction for vignetting too

1.45 looks logical….but that’s too good to be true. Imagine 10-22 on 1.45 it will be 14.5mm :) (and it still will perform good).
But who knows.

The 10-22 and other EF-S lenses already have vignetting problems, they would be practically useless at 1.45x
Look up some example pictures of EF-S lenses mounted to 1DIII bodies (you can do it if you remove the rubber on the lens), there’s no way that lens would function properly on anything less than 1.6x crop

Don’t have to imagine – the 10-20mm is an EF mount, not EF-s. I’ve strapped it to my EOS-500N (35mm film), and it’s bloody amazing. Except the image circle is too small @ 10-15mm; 16mm is just about usable.

Seriously, this is just a new take on someone’s wet dream of sensors that are FF, but crop when needed. When they can’t have that, then it’s gotta be 1.45x crop. Some brainiac figured out the lens would cover it.

Cool idea, since this is the kind of stuff that they don’t need to say to anyone before release. I mean, my local store told me that they’ve tried one for a couple of minute. It’s the kind of detail that you will not remark at first if the lens is on.
Also, I’ve been told built quality as good as 50D if not better (it’s subjective, I know). The coolest thing I’ve heard (it was rep pep talk) 7D ISO 1600 equivalent to 50D ISO 400… Please, don’t throw rocks at me, it’s only what I’ve been told.

Ok so a 35mm on a 1.6 crop has the same field of view as a 50mm on a FF so what would focal length be for a 1.45 crop to match a 50mm on a FF?
Reply
Jason Reply:

35mm
1.45 makes sense though, same pixel pitch as the 50D, but more pixels. Makes EF-S lenses a lot wider as well. A 10-22 becomes a 14.5-31.5 equiv, the 17-55/2.8 becomes a 24-77 equiv.

Crop 1,6x is absolutely perfect as it is. EF-S lenses are designed for it. And all 3rd party lenses designed for up to 1.5x crop are even better when used on 1.6x Crop sensors.
If Tamron upgrades its excellent 17-50 with a ultrasonic AF drive and IS and dont hike the price too much, they’ll sell a lot of them!
I loved the my 17-50 IQ-wise but sold and bought an EF-S 17-55 … because of the IS and USM autofocus

To be clear, a 35mm lens on 1.6 is equiv to 56mm on full frame, on 1.45, the 35mm lens is equiv to 50mm almost exactly.

From a manufacturing stand point, it’s not an issue with Canon since they make their own sensors. If anything, it serves as a reminder to the general buyer why Canon always has an advantage over other brand names.
HOWEVER, whether it’s possible for EF-S lenses to work with 1.45x crop is still unknown.
At this stage, it’s still a rumor. Just one more day to go and we’ll know the truth. :)

Whoops, sorry, for the question you were actually asking, you have to divide rather than multiply. I read carelessly and thought you were asking what a 50mm lens acts like on a 1.45x sensor, not what lens on 1.45x is equivalent to 50. My bad. So the actual answer is 50 / 1.45 = 33.3. A 35mm lens will do the job nicely; Canon’s 35 f/2 is inexpensive and very nice if you don’t mind the sound of buzzing bees when the non-USM autofocus motor runs.

“Apparently this is the limit so that EF-S lenses still work without vignetting.”
Vigneting is a non issue, most of it can be easily corrected in camera with “peripheral illumination correction”. One problem I see with this set up is that 1x viewfinder needs a bigger mirror that could “conflict” with the rear of the EF-S lenses. I have no idea how much tolerance is required for a bigger mirror to swing freely with the EF-S lenses. I honestly don’t think that Canon would be silly enough to break third-party lenses by introducing a new crop that would make them inoperable on their camera, that would really piss off a lot of people. Canon already has a lot of detractors (to be honest complaining mostly about their imaginary issues and non-issues) but bad press is bad press as inane as it is and they don’t need any REAL dissatisfied customers now.
For me, I hope that this rumor is true, it would give Canon a good edge over the competition I think, extra reach for those who need it, additional resolution for those who want it. Only few more house and we shall see…

The 3rd party crops aren’t a problem – they are spec’d to work with Nikon 1.5x crop APS-C and they use the EF mount – which means they have enough flange focal distance to mount on your 1Ds or 5D.
Reply
Scott Reply:

There wouldn’t be any issue with third party lenses, as they use the EF mount (I’ve put my Sigma 17-70 on a 5D before just for fun and it works, though it vignettes like crazy.
Third parties also make the same lenses for 1.5X, so I’m sure 1.45 would be pretty ok; I just don’t believe this rumor because the EF-S 15-85IS would have probably been a 16-85 instead. 15mm on 1.6x works out to 24mm FOV on 35mm. The spec sheet says the built-in flash has coverage equivalent to 24mm, so I’m sure it was to accommodate the new lens. So I’m sure it will be 1.6X.
I had originally been hoping for 18MP 1.3x, 8fps at around the same price as the 5D2, but at least this new camera will be less expensive and with those specs, it looks pretty interesting.

I was going to make that EXACT point. Everybody should understand, however, that the Peripheral Illumination Correction works by either pumping up the ISO or ‘brightening’ the areas in the corners resulting in reduced image quality in those areas. Further, PIC profiles appear to be only available for Canon branded lenses. Not a problem for me, but others might be miffed when the edges of the pictures from their SIGMA lens are significantly dark.

almost impossible…

is more reasonable

interesting! I would assume that 3rd party glass makers would mass produce their glass (therefore 10-20 sigma would also cover the 1.5x crop of nikon…) and all the other difference of the lens is just the mount.
Have anyone seen a *leaked* wine bottles at ISO 6400 by the 7D? looks pretty clean for me.. although there is always ways to fake the EXIF data.

Because lenses designed for the canon EF-S mount system protrude into the camera body in a way that, for example, makes it impossible to use them with a FF body, because the larger 35mm mirror will literally hit the inside of the lens when it flips up.
The concern is that a 1.45 crop system would necessitate a larger mirror, and then end up hitting the inside of some lenses. It’s unlikely that Canon would allow the mirror to hit its own lenses, but third party lenses, which were not designed with a 1.45 crop factor in mind, could be a problem.
MY take? Bogus argument: the tolerances necessary to match the Canon EF and EF-S mount are absolutely tiny. Show me a third party lens that looks different (at the mount end) by even half a milimetre than any other third part lens or official canon lens. It doesn’t exist. They’re *identical*. If Canon could make a 1.45x crop work with their lenses, third part leses will also work.

Third party APS-C lenses mount and function on FF, but at 17mm, the vignetting is similar to an 8mm Fisheye.

I really hope this rumor turns out to be true. It would be very strange and unlikely for Canon to introduce a new crop factor… but who knows. It would help explain the 18mp on a APS-C. Personally Id love to have a bit wider, more true, view from my L lenses while still getting a bit of extra zoom for sports.

THERE IS A BIG MISUNDERSTANDING HERE WITH REGARDS TO CROP FACTORS!!!
Canon is not introducing a new format. It is still APS-C
Nikon has been 1.5x crop as their sensors have been sized 23.6 x 15.8 mm.
Canon has been 1.6x crop as their sensors have been sized 22.3 x 14.9 mm.
Canon if this rumor is true are just making a 24 x 16 mm sensor that is the TRUE APS-C format size to make maximum use of the lenses.

Thats right.
Lets say for arguments sake the imaging circle diameter from an EF-S lens is 25mm and an EF lens is 36mm. Any sensor with a width and length less than 25mm would be able to produce an image without vignetting on an EF-S lens. So although there are variations in sensor sizes in the APS-C format they all work with EF-S lenses.
If Canon are making a new APS-C sensor to take maximum advantage of the EF-S imaging circle that is great news.
It is certainly not a new format and will work with all EF-S lenses unlike APS-H.

All this speculation is driving me batty. By the way, was anyone able to get a translation on the little box to the right of the “100% viewfinder” box, in the picture of the 7D poster.

Tamrons VC is AWESOME!!! It really is AWESOME!!! The bad news is that you end up with an image that holds super steady, but is still blurred because their glass is crap. Sorry Tamron, I own two of your lenses, and they just sit at home. Maybe I’ll sell them with my 40D when the time comes. Just call’um as I see’um.

That being said, I hope the 7D fulfills the needs/wishes of the average user and the birders.

Using your logic and the possibility of having the new 15-85 as a standard kit lens, the sensor will probably be 1.6 crop. You see, 15*1.6=24. I hope I’m wrong, though, because a 1.45 crop would be so awesom.

As I was saying in the previous 7D thread, what if its a 16:9 aspect ratio sensor? Sized at say 26.7 x 15mm instead ?
i) Its effectively a 1.45 crop ( in terms of area ) giving a 20% increase in sensor size. (15Mp + 20% = 18Mp) But 1.35 crop wide (works better in ‘wide’ mode ??) And 1.6 crop high .
ii) It will have no compatibility issues with EF-S or EF lenses. All that is needed is an automatic in-camera cropping mode. 16:9 EF mode in 18mp, 3:2 EF-S mode in 15Mp
iii) It will be excellent for HD video in native 16:9 aspect.
iv) It also effectively “encourages” users to upgrade to EF lenses without leaving out ‘legacy’ EF-S users. You just need the EF lenses to maximise the sensor, nothing lost if used in 3:2 mode with EF-S lenses or chose to use the 3:2 aspect ratio.
v) It can also use the viewfinder as found on the 1D as the leaked pictures seem to show.
A major win-win for Canon as it will be a great marketing trump card, while a viable alternative ‘wide’ users too!

I agree that your logic is good, but native 16:9 may not really matter since native HD video is only about 2mp (1920 x 1080 = 2073600). Also, all of the cameras that do have HD video, inherently have an auto cropping feature when they switch between 16:9 video and 3:2 still. I do think you’re on to something though, or maybe this is what you were getting at and I misunderstood. It would be good if they made a FF camera that auto-cropped when it detected an EF-S lens. Of course your resolution would go down, but versatility would be improved. Of course, if they would do away with all this APS-C and APS-H crap, all would be at peace in the universe.

FF with 18mp for those who want FF, and posibility to switch to 1,6 crop if you want to take advantage of the extra telephoto power of the lenses with this crop factor or the extra (8) fps???
maybe the leaks with the ef-s lense is a commercial trick, to saw that the 7D is compatible with ef-s lenses…(or at least i truly hope so!!!!!!)

You know that could happen, and with the dual digic IV, it could be a higher resolution than just 1080p, whch could let it compete with cameras such as the Red Scarlet.
Of course that’s just wishful thinking.

That thought had crossed my mind too; in fact, the original film APS-H size used a 16:9 ratio. The reason I don’t think it’s likely is that this camera’s primary purpose is not for video and 16:9 ratios are strange for prints. Eventually 16:9 may become a more standard format for cameras as people start to use their TV more and more for slide shows and video, but that’s still a few more years away. Nevertheless, I see no reason why the 7D’s video can’t be at least as good as the 5DII’s (at least in decent light)

On the other hand, Nikon has followed Canon’s lead in the use of CMOS sensors, telephoto VR lenses and TSE lenses.

The sensor will be bigger than Nikon’s (Actually Sony’s) sensor.
Competition is a great thing. Canon got burnt with the 1d III auto focus issues and the 5D II which has great features but no sealing and poor autofocus. I think Sony have shown that people want a good viewfinder and Nikon have shown they want a good autofocus and build quality. I think the 7D will have a great viewfinder, autofocus and build quality. You can thank competition for that.

Giving the camera the name of 7D is serious business. I still have faith in Canon and I know they thought it through. I’m sure it’ll make most people happy.
With an EF-S mounted to the 7D in the poster, I’d like to be realistic and say it’s probably going to be a 1.6x crop. If it is a 1.45x that could be pretty cool, and would sweeten the deal. I just don’t know how realistic that sounds. If that poster was a hoax from Canon and it was FF after all that would require me to put on some Depends diapers.
It’ll probably be $1899 upon release. If its any cheaper there’d be no reason to buy the 60D unless they drop that camera’s price down to the triple digits upon release. It seems like everything they’re selling is getting more expensive by the day. My bet is between 1800-2000. Sure if it were $1300 that’d be awesome :D.
As others have said…we’ll find out soon enough.

Fullframe I think you should learn some manners.
By way of explanation: with their current 1.6 crop cameras Canon support autofocus only to f/5.6 lenses. I photograph birds using a Canon 40D and 500mm f/4 lens and 1.4 teleconvetor = 700mm @ f/5.6. The lens, of course, autofocuses as Canon states it will. It will not autofocus with a 2x convertor = f/8 (even with taped pins)
I used to use a Canon 400D with 400mm lens and 1.4 tc = 560mm @ f/8. If you tape certain teleconvertor pins you can trick that camera to usefully autofocus at f/8. This doesn’t work with the 40D.
It seems to me that support for autofocus at f/8 is a near-run-thing and perhaps more light being made available from a larger mirror could tip the light equation to support autofocus at f/8.

Looks like AF support has decreased with the more recent models. The 40D definately disables AF with f/8 combinations, and I cannot trick it by taping the t/c pins, the 400D also disables AF, but I can trick it to autofacus by taping certain t/c pins.

If we’re looking at
50D: x1.6 with 15MP had noise issue.
7D : x1.45 with same pixel density should be 16.55MP
so 18MP still increases pixel density.
Question is, will it increase noise as well?

A 1.6 crop works by (1/1.6 x 1/1.6)x Area of FF
A 1.45 crop works out as (1/1.45 x 1/1.45) x Area of FF
Mathematically a 1.45crop works out to be 1.21x the area of a 1.6 crop.
Which working backwards => 18 / 1.21 = 15Mp.

In addition, if people actually bother to read DXOMark’s article comparing the sensor of the 500D vs D5000:
http://www.dxomark.com/index.php/eng/Insights/Canon-500D-T1i-vs.-Nikon-D5000
you’ll learn:
(i) “Canon EOS 500D sensor is nevertheless an exceptional sensor with a very small pixel pitch and very low RAW noise”
(ii) “the Canon EOS 500D is a bit more color blind in comparison with the Nikon D5000. To compensate, a greater degree of color processing is applied, which increases (chroma) noise”
(iii) “Canon EOS 500D behaves the same way as many other Canon cameras… that is, the readout noise becomes predominant and… explains why the Canon EOS 500D’s dynamic range does not increase between ISO 200 and ISO 100 and obtains only 11.5 eV as its maximum dynamic range measurement”
(iv) Pixel size has NOTHING to do with the performance of the 50D/500D sensor

Does anyone also thinks that it worth buying 5DII instead of 7D?
By rumors, 7D costs $1800 while 5D is $2699.
Buy for this 1/3 increase in price ($700) you get FF.
If you add 24-105L lens into calculation:
5DII + 24-105L = $3500 + super-duper extra fine pictures
7D + 24-105L = $1800 + $1200 = $3000 + noisy pictures.
cons: 4fps instead of 8. (I personally do not need 8fps)

But if you think about it from another point of view, e.g.
John Doe has a EOS 30D with EF-S 10-22 and EFS 17-55 F2.8
In order to upgrade to full frame with equivalent lenses, he must not only buy a more expensive EOS 5D (/Mk ii) camera, but also the EF 16-35 F2.8L (or EF 17-40 F4L) and the EF 24-70 F2.8L.

Using the link above, you can see what the 10-22 EF-S zoom lens can do when adapted to fit on a 1D mk iii (1.3 crop) ; the vignetting is not too bad. If you scroll you can also see the results on a 5D camera. Strangely, the vignetting is more important when the 17-55 is used on 1.3 crop camera.

August 31st, 2009 at 4:26 am
sigma 10-20 works on 1d and vignetts at 10mm but at 11mm it’s fine.. No mirror problems and you get really wide angle..
So i dont think there’ll be any mirror problems, only vingnetting with sigma lenses and 1,45crop
Reply
August 31st, 2009 at 4:31 am
This is very credible. Canon only need to worry about the increase in the distance of the vertical dimension of the mirror divided in half. And only Canon EF-S lenses actually protrude more past the lens flange, the 3rd-pary lenses are just EF mount lenses with APS-C sized image circles. So let’s say the EF-S 10-22mm is the only lens that would give a potential problem, since it would have its rearmost element closest to the sensor, and thus, the mirror. Canon would only have to measure how much additional clearance they would need to clear that rearmost lens element. And I think they figured it out that an increase to 1.45x is the largest they could do it without the larger mirror hitting the rearmost element of this EF-S lens.

A 16:9 sensor is a very good idea (similar to those Panasonic point and shoot cameras that have this).
Possibly too groundbreaking for Canon to implement.
It would really send a message that Canon is serious about video on SLR cameras.
I still stand by my comment that Canon is holding everything back until Nikon releases it.
High res monitors released directly after Nikon did.
14mm MK II released directly after Nikon’s 14mm zoom.
Video released directly after Nikon did.
etc. etc. etc.
I understand why they do this, but it would be nice if they stretched their neck out a bit and let a few features out without being forced to release them just to keep competitive.

I can’t wait for to have a HD video capable camera but I have no idea why 16:9 is a good idea for a SLR stills camera. 16:9 is a TV ratio, 3:2 is pretty standard for photography. I couldn’t imagine turning my camera portrait style very often with 16:9.
Besides, with 18MP, I’m sure you can afford to crop off the top and bottom.

Yes, sensor size is indeed 22.3 x 14.9 mm. That is a 1.6x crop.
In addition:
1) 內置閃光燈發出的光脈衝可以通過無線信號，與具備無線從屬功能的SPEEDLITE 580EX II、580EX、430EX II、430EX、420EX等進行信號傳輸
Yes, wireless flash control indeed. :)
2) Available end of Sep
3) AF with f/5.6 or faster lenses only
4) 19 AF points only. No more. But AF points can be grouped into 5 regions for AF tracking.
5) Exposure compensation extends to +/-5 eV
6) Spot metering can now be tied to individual AF point
7) New imaging sensor electronics improves signal to noise ratio
8) LCD is new Polymer Network LCD.
9) Battery is LP-E6 (same as 5D2)

Again and again, if people actually bother to read DXOMark’s article comparing the sensor of the 500D vs D5000:
http://www.dxomark.com/index.php/eng/Insights/Canon-500D-T1i-vs.-Nikon-D5000
they’ll learn that:
(i) “Canon EOS 500D sensor is (nevertheless) an exceptional sensor with a very small pixel pitch and very low RAW noise”
(ii) “the Canon EOS 500D is a bit more color blind in comparison with the Nikon D5000. To compensate, a greater degree of color processing is applied, which increases (chroma) noise”
(iii) “Canon EOS 500D behaves the same way as many other Canon cameras… that is, the readout noise becomes predominant and… explains why the Canon EOS 500D’s dynamic range does not increase between ISO 200 and ISO 100 and obtains only 11.5 eV as its maximum dynamic range measurement”
(iv) Pixel size has NOTHING to do with the performance of the 50D/500D sensor

But that’s the point, isn’t it?
Technology improves sensor quality despite increase in pixel count. D3x vs D3 is the prime example.
Do NOT dismiss a sensor just because it’s got higher pixel density. It’s the end results that matter.

In order to exchange IR with wireless non-optical system canon will need to replace all existing flashes or at least release new versions. It wouldn’t be canon if price for such will not doubled. Take for example of external wired remote for 50D, canon sells it for ~$300 which is almost price of Rebel :)

Though this could explain why Canon is also announcing 2 new walk around lenses, they may have less vignetting? Dont they already offer several EF-S walk around lenses, why do we need 2 more? This is from memory but I think we already have…

there are indeed too many EF-S’s that start at 15, 17 or 18mm:
18-55 f/3.5-5.6
18-55 f/3.5-5.6 II
18-55 f/3.5-5.6 IS
17-85 f/4.5-5.6 IS
17-55 f/2.8 IS
18-200 f/3.5-5.6 IS
and if the rumour is true then also;
15-85 f/3.5-5.6 IS
18-135 f/3.5-5.6 IS
most boring is that not only there is a considerable focal range overlap among them but also that the great majority of them are f/3.5-5.6 . if the longer ones like 18-200 and 18-135 were possible to design with that maximum aperture, why can’t the shorter ones like 18-55 or 15-85 be f/2.8-4.0 for example?!!! The only fast one is plagued with dust, softness and price-tag problems. Canon keeps on coming up with new designs every know then but fails to ever notice what are the problems with the existing ones, they remind me of a joke that someone whose name was something like “John Catastrophe” kept on changing it to “Jack Catastrophe”, “James Catastrophe” …, without ever realizing where is the problem, funny but tragic in the same time!!

From the link a few post above it’s clear the sensor is an 1.6 crop.
Anyway, it also seems the sensor has been redesigned focusing on increasing the efficiency of light coupling to the sensor.
A more efficient sensor would imply more signal for the same noise so it might be able to yield equivalent SNR to lower density sensors.
My perception is that Canon image has been quite damaged by the poor quality of the 50D, and many users are starting to think seriously about Nikon migration.
I think this camera is just a “disguised” 60D addressed to solve this problem (and as the gap between 500D-50D-7D becomes smaller it would make sense to merge the xxxD and XXD series. Just my speculation!).
If the marketing plan is to fight the D300s, I’m quite certain that Canon would not go to a super high noise camera, specially in a market segment that is quite aware of the megapixel race pitfalls,
We must wait for the first reviews, all the FF/1.6 discussion is meaningless until then.

It’s not about the quality it’s just that 50D is “obsolete”.
I was “too much” incremental, and has been clearly surpassed by competition in functionality. It could had made it if the image quality was best in class, but again no. The poor sales are a clear prove of this.
As of today, if I had to buy a camera (figure I can’t wait for 7D) I would go for a “half-price” 40D or some other brand (if i had spent little on glass of course).
