Crop lenses on FF cameras

If you have a third party crop lens that does not intrude into the camera body, you can use them on a FF body.

NOTE: if you use a lens that protrudes into the body, you run the risk of your mirror hitting the back of the lens and damaging your camera. DO NOT USE SUCH LENSES!

The three shots here are:

1) with a sigma 30F1.4 crop lens.... note the severe amount of vignetting. You could crop this image to a slightly wider field of view as on a crop camera.

2) With a Tokina 11-16 F2.8 lens at 11mm. Also a severe amount of vignetting, you could crop this image to a slightly wider field of view than a crop camera.

3) With a Tokina 11-16 F2.lens at 16mm. A bit of vignetting at the corners, but the whole image is usable....

TDP Image Quality posted -- 70-200 f/4L IS II: it's not much better

Mt Spokane Photography said:
The optical performance of the existing lens was so close to perfect, that even a little is a accomplishment. Looking at just center sharpness is like reading the specs on a Soiny camera. You need to look at everything. The lens had a substantial upgrade across the board, but I would not upgrade from thye old one unless it were my most used lens and my old one was wearing out.

I agree wholeheartedly and would add I would only purchase if you currently did not own a 70-200 f/4 lens. Otherwise, I see no reason not to. Looks great.

EF-X Mirrorless concept

ahsanford said:
Again, on the original topic of the mount, I am skeptical Canon will go for some transformer/telescoping mount. I'm also skeptical Canon will pursue the EF-X concept listed here as I honestly believe they will turn off the 'keep it small' crowd with that move.

Like it or not, pragmatism be damned, I think Canon is going thin mount and small with one of its first offerings to court the 'keep it small' crowd.

- A


Agreed....if we go thin (flange distance less than 44 mm) then "EF-X" still is needed, as we will need a FF image circle coming from a lens with a shorter flange distance.
So, what I think will happen is that Canon will not want to limit their future camera body sizes to fit lenses designed for a mirror box that is no longer needed. I expect 3-4 "EF-x" lenses to be introduced with a FF mirrorless camera.


But...let me get your opinion on this as a "sexy" and "elegant" solution. The Canon FF mirrorless entry has a shorter flange distance, but has a built in lens element in the camera body that takes the EF image circle and broadens it to fit a FF image sensor in a distance of less than 44 mm.


So, say a 25-30 mm flange distance, so still more compact, but enough room for that lens element. We would no longer remove a lens and see the sensor, rather we'd remove the lens and see some glass.


Has this already been suggested? Thoughts? Could get odd when the focal point occurs within this new lens element, but maybe it is possible. Also that whole "physics," "science," and "reality" may be issues as the same element would need to work with light coming in at different angles. I do like how the listed focal lengths on the lenses would still be the equivalent focal lengths, even though they would technically be a little different, FOV would be the same. This only happens if you have a 44 mm flange distance either natively or with an adapter or if we are bending light with a lens element and a shorter flange distance, as suggested.

Industry News: The First Rumored Specifications of Nikon's Full Frame Mirrorless Cameras

RickWagoner said:
One main advantage of mirrorless is the weight and size, but this does not work out in the real world on full frame mirrorless as the weight and size of lens itself is determined mostly by focal length, aperture and then a little by build quality. Of course you can (and some companies do) go a smaller body but then you have a weird unbalance with a fast zoom pro quality full frame lens.

Only a minority of people use fast zooms , long teles or other big lenses most of the time or all the time.

Most frequently used foal length range 24-85mm can profit massively from shorter Flange Focal Distance on mirrorless cameras. A mirrorless FF setup of camera + 16-35/4 plus 24-70/4 plus 24/2.0 plus 35/1.8 plus 50/1.8 plus 85/2.0 can be made *sgfnificantly more compact and lighter* than a DSLR setup. Need for faster lenses is much lower today, now that any decent camera delivers excellent IQ even at ISO 6400 and on FF subject isolation at f/2.8 is more than sufficient for many subjects/styles. I want such a setup, and many others want it too. And for birders, wildlifers, sports photogs there will be chunkier mirrorless cameras to go well with bigger lenses. No problem. There will be multiple models and sizes available. Just like with DSLRs.

So no need to constantly try and obfuscate or "explain away" the very real size and weight advantages mirrorless systems allow for and will bring for the vast majority of use cases and customers.

On top of that come all other advantages of mirrorless cameras. WYSIWIG EVF, 100% silent, 100% vibration-free, 100% free of moving mech parts, 100% lubricant-free - as soon as we finally get global shutter sensors - all the way to significantly lower cost thanks to much simpler calibration and QC routines and fully automated production - which will *hopefully* also lead to lower prices for us, the paying customers. Provided, we keep asking for it and pushing Canon and competitors, rather than "showing pre-emptive, endless understanding for their oligopolist profit maximizing at our expense" - as seen so often in this forum. :-)

Help getting started with Studio Lights

Mt Spokane Photography said:
I'd expect that the meter will soon be of little use, and you can adjust the settings from experience and be right on more than you are with the meter.

...useful though when you're trying to quickly get ratios right with a multi flash setup. But reality is I do use the flash meter a lot less than I used to.

first shots from my sigma 105mm f1.4

BeenThere said:
It’s now up on lenstip review. Stellar resolution, but AF seems to be an issue when off the center point.

yes ... I saw that.. not so with 135..for me and others..
odd..
well now I feel good about my choice.. 135 f1.8
the 105 sharpness seemed 'NEARLY' as good as the 135..
but for me I chose the 135 because of
....reach
... size/weight
....the edge in sharpness.. it seems coma was there for the 135 too.. I could not see that... of course
..
I mean we are splitting hairs..
but I still have my hair ...mostly..

but the dang thing crowded out my other cameras and lenses..
rude...
so......the bokeh is the best now.. I swear..past 85L f1.2 mk ii ....
my little trials .. made me a believer..

and 135 is just fine...
as a bokeh runner-up

I want to say my 135 snaps to exact focus.. on 1dx2...
a stream of license plates cars passing....bike riders flying by...
yup!.... in various light... it is so dead-on...
and at f2 it is 10 clicks above the Canon 85L f1.4.. re: lens tip
I usually want I.S. at these distances.. I love I.S.
but this thing is so solid..I swear

I miss the 105 a bit...
squishy blobs....
haha... bokeh nuts... me too

sigh

I dont want to carry an apartment fridge when I go for a walk..

this forum is so good... I learned so much.. each week...

More Canon Gear Appears for Certification, Including 5 New Lenses

jeffa4444 said:
robotfist said:
Canon definitely needs to get on the ball and release some new lenses. Where is the 24-70 IS?? Where is the new 50mm?? One look at the DXO charts and you can see how far they are falling behind Sony and Nikon in both lenses and cameras. Canon doesn't have one lens in the top 25. Not one. Their 35mm II shows up in the 28 slot. I know tests aren't everything, but they aren't nothing either. They do tell a lot about lens sharpness, chromatic aberrations, etc. And while Canon still owns the best color science and menu operations for their camera bodies, they can't ride on those things forever, because the competition is hard at work in the lab, chipping away at Canon every day. Sony was a blip on the chart 10 years ago, and look how far they've come? Well it's clear that they aren't stopping. If Canon keeps going at the pace they're going, I foresee a big upset happening in 5-10 years.

Please don't quote DXO the most arcane testing procedure. We test cameras & lenses everyday for high end cinematography. Lenses are tested on the MTF bench, on and off axis, on a F stop (T stop) machine, and projected by specially made projectors set-up precisely in a dedicated room with various aspect ratios projected to see to what format the lenses can cover and to what degree they have fall-off or abberations. We test the cameras in a number of ways and then finally test the lenses on the camera.

You maybe surprised how many Canon lenses have been used on images that will be projected onto 53 feet diagonal screens or larger both in a still image (for assessing real life images rather than charts) or moving images.

In our industry DXO are seen as amateurs.

My suspicions about DXO:

They started out collecting data for the purposes of building profiles for their raw converter. As such, it requires camera+lens. Then someone got a “big data” idea and decided to publish it. Things got out of hands when they came up with scoring to drive traffic, because that opens the can of dependent variables worms.

If one uses the data selectively, it’s very valuable. It is just unfortunate that DXO has decided to stylize itself as a testing lab.

Industry News: This is the New DJI Mavic II Pro Drone, Official Announcement Delayed

HTML:
<iframe width="728" height="409" src="https://www.youtube.com/embed/q_1XKDkjGu4" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe><a href="https://dronedj.com/2018/07/06/breaking-news-dji-mavic-2-photo-leaked-online/">DroneDJ</a> has gotten their hands on images and specifications for the highly anticipated DJI Mavic II drone. There is also a possibility that we’re going to see a “non Pro” version of this drone as well.</p>
<p>DJI originally had an event scheduled on July 18, 2018 to announce the new drone(s), but that has been delayed with no rescheduled date as of yet.</p>
<p><strong>From DroneDJ:</strong></p>
<blockquote><p><strong>Improved form factor</strong> – The new <a href="https://dronedj.com/2018/06/15/dji-would-like-you-to-see-the-bigger-picture-on-july-18th-possible-mavic-pro-2-announcement/">Mavic 2</a> drone is sleeker and more aerodynamic than its predecessor, something we expected all along. At the same time, it is very much recognizable as a DJI Mavic Pro. Same color, same shape and the same folding mechanism it seems. Battery mounted on top and towards the back. Similar to original Mavic and not like the Mavic Air.</p>
<p><strong>What’s in a name</strong> – The drone is labeled Mavic 2, which may mean that there still will be a Mavic Pro 2. The bands on the legs of the original Mavic Pro are gold colored. The one shown in the photo is silver, which may mean the advanced (or basic) model if you go by previous DJI drones (Phantom).</p>
<p><strong>Two different sensor sizes</strong> – The photo seems to show two different sensor sizes. The one mounted on the drone in grey could be a 1-inch sensor, and the one in black on the table perhaps a 1/1.7 sensor? A big sensor will surely help you to “See the Bigger Picture”.</p>
<p><strong>Gimbal</strong> – The photo also seems to show a removable gimbal, a la the GoPro Karma. If you look at the picture closely, it seems that the gimbal might just slide into the drone and thus can be used separately as well. To the left, on the table, you can see the second gimbal with what appears to be a significantly smaller camera/sensor size and a small screen. There is also a lighting connection presumably for charging. The gimbal mounting system seems to be a lot more sturdy and durable than what we currently have in the Mavic Pro.</p>
<p><strong>Motors</strong> – The motors seem to be of a larger size than the original Mavic Pro</p>
<p><strong>Propellers</strong> – Are not the ‘quiet’ ones we have seen on the DJI Mavic Pro Platinum and Phantom 4 Pro V2.0. Maybe DJI will reserve that option for later in the product lifecycle of the Mavic 2?</p>
<p><strong>360-degree obstacle avoidance</strong> – The new Mavic 2 seems to have at least front and side obstacle avoidance cameras/sensors. Very likely it will feature the same at the bottom and at the back of the drone. Not at the top, however.</p>
<p><strong>Foldable legs</strong> – We can’t see the rear legs of the drone but the front legs seem to fold sideways like they do on the original Mavic Pro.</p>
<p><strong>Zoom lens?</strong> – When you look closely at the lens of the camera it does not seem to resemble the lenses OsitaLV showed earlier today. Unless the gimbal had been removed. <a href="https://dronedj.com/2018/07/06/breaking-news-dji-mavic-2-photo-leaked-online/">Read more…</a></p></blockquote>

Is Maybe "Mirrorless" Not as Much of a Thing as Everyone's Saying?

Cory said:
brad-man said:
Let me get this straight. You've been happily shooting with a DSLR for (presumably) many years now, but on a whim you bought some kind of mirrorless camera and used it for a whole day to do something, and you're "not feelin' it"? What kind of "thing" is "everyone" saying mirrorless is? Thank you Captain Vague.
Pretty much.
I could really use a 2nd camera for video and everyone says how great the M50 is so it seemed like a no-brainer.
Had a major fail interviewing a triple amputee Veteran that was 100% my fault, but maybe wouldn't have happened otherwise. I nearly threw up.
Then, when I went to download some stuff to the computer I couldn't find a USB cable to fit nor instructions anywhere how to download. Probably 2 stupid reasons, but immediately said "I'm ****** out." and discovered, too, that I just like my DSLR's.
So now I just posted for affirmations, but I did first look in the mirror saying that I'm good enough and people like me; even if both are untrue.

You’re using a camera rumors forum to solidify your self esteem? Good luck with that.

Four More Unreleased Canon Lenses Have Shown Up for Certification

Mphotostyle said:
It makes sense for EF 24-70 f/2.8L III USM to be released, as the version II has been around for a few years and it's lacking the IS, which stopped me from buying it last month, when canon dropped the price by $710. The sale ended 2 days ago and Canon still gives $610 off the price now. The lens will stay black, so unlike the EF 70-200 f/2.8L III IS USM which seen just a minor improvement, I think the EF 24-70 f/2.8L III USM will be a compatible match and the price of the new lens will be $300 over the base price of the current version (compare EF 100mm f/2.8L Macro IS USM & EF 100mm f/2.8 Macro USM) price = $300 difference

One of those 100mm Macros is an L lens, the other is not. And both have been around for quite a while, since 2000 (non-L) and 2009 (L IS) respectively, so the price has settled a bit from when they were new. Like many non-L lenses that have not been refreshed since the 1990s (400/5.6, 300/4, 50/1.4, 85/1.8, 100/2, etc.), I doubt we'll see another 100mm non-L macro.

The EF 24-70mm f/2.8 L II is an L lens, and it has only been six years since it was introduced in 2012. Eight to ten or more years is the normal "refresh" cycle for L glass, not six. Any upcoming EF 24-70mm f/2.8 L IS (if it has IS it won't be a III, it will be the first EF 24-70/2.8 L IS) will also be an L. But if it is as good optically as the EF 24-70mm f/2.8 L II, I would expect it to debut at about the same price (in yen) as the EF 24-70mm f/2.8 L II was introduced. The difference in the exchange rate between 2012 and 2018 means that the number of yen that bought $2,300 USD in 2012 will only buy about $1,900 USD in 2018.

The reason for the "fire sale" prices at $1,600 USD may well be to clear out existing inventories if an EF 24-70mm f/2.8 L IS is introduced this Fall. We saw a similar drop in the price of the EF 70-200mm f/2.8 L IS II a few weeks before the announcement of the EF 70-200mm f/2.8 L IS III, and that is not near the upgrade that a 24-70/2.8 with IS would be.

Is it realistic for the canon 7d iii to match the image quality of nikon d500?

Cryve said:
CanonFanBoy said:
Not sure if it considered low light, but I shot a couple of high school football games at night with my 70D (when I had it) and I thought if focused very well and quickly with an EF 70-200mm f/2.8L IS II. Noise wasn't bad either. Surely the 80D is better than the 70D. (Blame the poor color on my having the workspace setti9ngs wrong in PS at the time.)

I had problems with it nailing focus down to the milimeter. sometimes it was off by just a few milimeters which was annoying because i had to take many shots just to get one really sharp one. Apparently that was also a problem with many of the 7d ii cameras at release.

As for lowlight it had problems nailing focus on low contrast black birds, the head isnt in focus. Of course this is just one example of a lot i had over the months.

Well, looks a little back focused to me.

FF mirrorless: What will be first lenses out?

Adelino said:
If Canon release FF mirrorless that is not EF compatible (I hope it is compatible), what will be the first lenses out and what will be the time frame for releasing lenses? What are your gueses and hopes?
My hope would be 24-80/4 integrated into the body (no mount for interchangeable lenses needed).

Then I may even buy one or two.

Latest Nikon FF mirrorless rumor: 24 MP and 45 MP models

Mt Spokane Photography said:
Prices of Mirrorless cameras are way too high. The cameras cost less to make, and should be more reliable due to fewer moving parts. Eventually prices will drop, but for now, manufacturers are raking in profits.

They are high because they can be. Unless what you are shooting something that demands an OVF*, one could argue an FF mirrorless setup does the same job as an FF SLR in a smaller footprint. That has value that manufacturers can ask more for.

*I prefer an OVF myself, mind you.

- A
Its about competition and product availability. Once we have multiple competing products, prices will drop. Canon usually drives the prices down. They engineer a product to have the lowest possible price, not a penny goes into making one that has not been carefully though out. They can cut prices below the competition and still make a nice profit. But ... They will not cut prices unless they see a advantage, like gaining market share.

Canon are the sharks of the industry but I prefer shooting with my blue-fin tuna.

Soft edge to all of my photos???

privatebydesign said:
kat.hayes said:
I am using a studio light with a shutter of 1/250. Please pardon my ignorance, I am new to all of this. I have been using these settings for many shots I took yesterday while practicing with the light and I did not have this issue. Perhaps my settings were slightly different and I didn't realize it? What is the issue?

Thanks!

No issue, your camera sync speed is not 1/250, try 1/160 and the shutter shadow will go away.

Surely this. Shoot faster than sync (without HSS engaged) and this will happen.

See 1/200s vs. 1/250s example here:
https://digital-photography-school.com/understand-flash-sync-speed-so-you-dont-sink-your-photo-shoot/

(This article is off on the specifics: all Canons are not remotely 1/200 sync! Check your manual or TDP)
