the trouble with these massive file sizes is that it shows the lenses to be less than perfect. i still think that a great lens and a reasonable size sensor would beat and average lens and massive sensor.

I would argue that it shows there is a renewed need for image stabilization. Or, alternatively, that the user doesn't have nearly as steady of hands as they think they do.

I can't say much about consumer lenses, as they are mass produced and use lower quality materials for the optical glass. But professional grade lenses, particularly Canon L-series telephoto lenses, are made with much higher quality glass and usually hand crafted for precision. I believe Canon's latest Mark II telephotos are plenty capable of resolving enough detail for a 46.1mp sensor. I recently used the new EF 300mm f/2.8 L II IS, the successor to what was previously considered Canon's sharpest lens ever, period. The sharpness of that lens is unbelievable, and was fully capable of keeping up with my Canon 7D for birds (lots and lots of super fine feather detail). Even my slightly older Canon EF 16-35mm f/2.8 L II lens is capable of keeping up with the resolution of my 7D, and it isn't anywhere close to the engineering feat that the 300mm lens is.

The 7D, BTW, has a pixel pitch about the same as a 47.6mp FF sensor would have... So I seriously doubt anyone will have a problem with lens resolution, so long as they use professional-grade glass, and use newer lens models.

So i was looking up diffraction limits and i noticed that on my crop body, 60D the diffraction limit is f/6.9.

What does this mean in practical terms? If a lens i have is sharpest between f/8-f/11 should i still keep the aperture greater than f/6.9 because of this limit?

Thanks guys

Diffraction is a property of lenses, not sensors as your title suggests. Therefore, a 60D does not have a diffraction limit.
Resolution of a lens depends on the lens design, and will be highest at different apertures for different lenses. However, having a high resolution is only one part of a high IQ. As you stop down, most lenses have reduced distortion, and reduced CA's.
Where a sensor comes in, is that sensors with more resolution can see diffraction better, but it is caused by the lens.
As you can see in this chart with a 15mp Canon 50D and 40mm f/2.8 lens, the resolution does not vary greatly out to f/8. The Chart below it shows basically the same pattern for the 5D MK II

40mm on 50D



40mm on 5D Mark II


Now, here is the Canon EF 100mm f/2.8 USM Macro lens. It shows the effects of diffraction really taking hold at f/16 and f/22.

100mm on 50D

If I'm not mistaken, you said you were looking for FD primes for an FD bayonet equipped Canon 35mm, correct?

Almost any of the primes mentioned so far will serve you well on any FD bayonet camera body. I use an FT QL from 1966 and an FTb QL from the following year and love all of the following on either of the two Canon film bodies I have.

FD 24mm (they make a couple of different versions of this)
FD 28mm f/2.8 (also with different versions)
FL 35mm f/3.5 - Excellent every day, all around lens
FL 50mm f/1.8 (the 1.4 & 1.2 jump exponentially in price. the 1.8 delivers plenty of light to the film plane so don't get too caught up in which one is best)
FL 55mm f/1.4 - probably the sharpest lens I've personally ever put on any EOS EF Mount camera body - even with an EOS/FD adapter in between.)

All of the 50mm primes are matched for the performance of the metering system as thery were essentially designed around the 50 1.4. Focus sharpness will, of course, be dependent upon your eyesight and how well you see through the finder. Split screen focus was stock for all bodies back then, too, so that helps a lot in darker situations.

I know the price will be high, and I'm budgeting for that.

Yeah, I actually figured as much when I looked at your signature, but that was after I had already posted my comment : )

Anyway, here's an interesting thing: as reported on NL, Foto Konijnenberg in Netherlands is actually already taking orders for the 200-400, although you can currently only order one bundled with either a 1DX or 5DIII and they're showing it as "out of stock". If you substract the price of the camera from the bundle, it makes the price of the lens itself to be around €10,000, which means that it will probably be, indeed, $10,000 in the US. And it also means that the announcement should be right around the corner.

just wanted to thank you guys who've spoken so highly of these flash triggers. i bought a set last week and I'm happy, and impressed. Even the firmware update went smoother than i could have hoped for. I've got a wedding in two weeks that i'll be soloing and these are going to be very handy. Thanks.

I never understood anyway what a photo camera gotta do with shooting videos. Its a gimmick they just added to suck the money out of videographers pockets

NOTE from MOD: Post moved from EF 300mm f/4L IS gallery (best to keep all images in lens gallery topics to that lens).

I looked at this but instead went with the Sigma 120-300mm 2.8. It is very sharp.

With the 2x Converter remains sharp, retains auto focus and becomes 240-600mm f5.6.

The first image at 600mm. Shot from over 230 meters away on a 5D3


Untitled by P A - Photography - 5d mk3 arrives today!!, on Flickr

Launched off of a Military Sealift Command Supply ship (USNS) from the helideck. A team from Guam came aboard to do the launches and control (Remote control). This was in support of an International Naval Exercise near Singapore.
The ship launched five drones that day, and none were shot down by the players... though they tried!

I also have pictures of the drone recoveries. (They are brought back near the ship by remote, then parachuted into the sea, where they are picked up. I'll try to find those pics in my mess, and post a couple.

Hello comrades! Just came back from morning walk. L'vov. Canon 60D + 18-55 (old, from Canon 350D).
Here are my photos. I would be happy to see yours city mornings here!

Thanks everyone for the tips! Very much appreciated and will make notes of it!

A couple of responses here:

-I forgot to mention that I have yet to touch PS and am trying to stay away as much as possible. I like to keep the image of the real person. Not taking out acne/scars or whatever may appear on a face. I am sure one day I will have no choice but to dive in. But for now, i want to keep the image as true as possible. Like the image that someone posted where he took it into PS. To me it looks blown out and just can tell it was post processed like crazy. I appreciate the help though!

-Still working on that posing thing. That last image of her squatting down(looking back it does seem as if she is using the bathroom) she wanted badly.

-I do need to watch out for those low angle shots. A couple of times i setup for the shot and had to go over to her to adjust the dress to not show to much. In those really low angle shots I was actually laying on my back on the ground shooting.

-I noticed some of the soft/just not in focus shots when i first got them into lightroom. I know how the triangle works with iso/shutter speed/aperture and how the aperture affects the background and such. However, I made a rookie mistake in not changing my aperture much at all. For almost all of these shots it was at 1.8 when for the wider shots i should have bumped it up to keep her sharp in focus. Definitely something i noticed and kicked myself for.

-Definitely could have used a fill flash in some shots. Will keep that in mind!

I think every one knows what he meant and if not it is you who has a interpretation failure.
He rather take a 75Mp in the future (every one understand that) and shows my pictures, was wrong with that?

You said earlier that you saw softness even at F- 4 etc.There is is no real softness at f- 4, but the image was not properly sharpen when I showed it first time . Then you are right about difraktion affect at f-8 but that is common knowledge
for almost every one.

Why would you assume he suddenly moved to some hypothetical "future" context, when the context at hand involved 75mp only as an extrapolation from the pixel density of the V1, and the argument at hand was explicitly regarding the V1's IQ?

TexPhoto said:

Sounds like focus breathing. Also when you are close, camera placement can have an effect.

It is interesting though because when you have one 70mm lens, its 70mm, but when you have 2, suddenly there is an issue.

Click to expand...

True... with 2, a "Frame" of reference is born

Unless I win the lottory, otherwise this is just a dream:
1. Canon 50mm f/.95
2. Canon 200mm f/2L IS
3. Canon 600mm f/4L IS II

: : : : : :

While I agree that you most likely need things adjusted by Canon, using AV mode may not yield the exact same shutter speeds. Tripod, mirror lock up and 2 second timer definitely helps, but shooting in manual with your aperture and shutter speed locked in should guarantee you are looking at the exact same exposure.

3 lenses to lust after!!

Beautiful shots, love the colours and the lighting, fab!

A company like Canon is doing alot of R&D. The magic phrase for prototypes like the 120MP sensor is "proof of concept". You are testing certain aspects. The 120MP sensor has shown that you can do multiple line read outs at a time and produce stunning speeds, which is now famously featured in the 1DX. There you go, a 2010 prototype lead the way for 12 FPS. Another issue they observed with the sensor was, that you are getting diffraction blur at such a wide open aperture that it is currently (2010) not managable to deal with in a finished product.

Click to expand...

Even with diffraction at wider apertures, a 120mp sensor is going to resolve far more detail than a lower resolution sensor. Even stopped down to f/8, f/16, etc. the 120mp sensor will still be better...you just get diminishing returns. At NO POINT, EVER, will a 120mp sensor produce WORSE results than a lower resolution sensor. That is a common misunderstanding, but a misunderstanding nevertheless. Diffraction, once it occurs, does not degrade IQ below that of a lower resolution sensor. At worst, you would get the same IQ as a lower resolution sensor. It's an asymptotic relationship.

A 120mp sensor would be entirely viable today, and would probably produce better IQ as well. Not only that, you could ALWAYS scale your images down to reduce noise, and still print large. Or simply keep it at native size and print HUGE. No matter how you slice it, diffraction is not the thing keeping a 120mp sensor off the market.

I'm having a hard time selling my 5D classic for a good price, because I can't tell buyers what the shutter count is. Based on this experience, I would have to say that the lack of a shutter count feature reduces the resale value.

I could send it in to Canon, but the last time I sent it in for focus adjustment they charged me $200. They did include a shutter count report at that price, but I had to specifically request it. I had just purchased the camera used and guess what? I wanted to know the true shutter count! LOL

Btw, who is really trying to catch up to who here? Competition is good, so expect the race to go back-and-forth.

Imho atm Canon is hard-pressed to catch up to reality and sanity again. Given the current feature/price combinations this doesn't seem to be the usual volatile "AMD in front of Intel, then the other way around" situation, because once AMD falls behind Intel they concentrate on releasing products with more attractive prices. Conservative Canon with its immovable userbase seems to try "more of the same" no matter what the competition is up to (like 6d vs d600).

That's a nice way of pussy-footing around who's really in top spot.

10s timelapse = between 240 and 300 frames depending on your movie frame rate.

Can add up quite quickly. Not just on the shutter, but on the aperture blades.

@Marsu42

I guess it'll take Canon aps-c at least another 5 years to get to 5d3 level, but I'm certain they'll get there eventually - the limitations of aps-c are lens resolution and pixel density, I don't see why there would be physical any constraints to low light capability.

Click to expand...

If Canon were to release a new APS-C camera with 10MP but 5D3 low light performance would anybody buy it?

7D is niche, and rebel target market get sold on silly things like numbers.

What about an APS-C camera with 6 or 8MP with 1DX low light performance?

I personally don't really need anything more than 6MP if I'm being honest, and I'm sure most of the APS-C market are the same...

Canon reduced the resolution of their premium compacts a while back and have reduced the resolution of their flagship model... all for IQ dividend.

Apart from the benefits in pixel size, the vast majority of EF lenses would better fit with the lower resolution sensors and have more usable aperture range too.

Folk may salivate at the D800, I don't, I wanna go 'backwards'!

Do you own the 100mm? I do and i love it. The picture quality is spectacular and provides added functionality. The 135 is amazing but so is the 100.

Click to expand...

+1 ... the 100L is the most fun lens, too, because it has (nearly) no min. focusing distance, so no need to get it only for 1:1 macro but rather for general closer-up nature shots. And with the hybrid IS and sharp f2.8 it's very versatile, too - definitely overkill only for macro shots, but a great choice since you seem to have no budget constraints

I've had an Ex580 II for nearly two years and it gets a lot of use - its has never let me down.

To answer OP's question, I'd suggest the Ex580 II

Cheers

The two Pixel grips for the 5D MK lll I've used have good fit and finish and seem fine, especially for the price.
The shutter and AF buttons work well.

The problem is the electronics. When the grips are turned on, the multi- controller on the camera body doesn't work properly. Turn off the Pixel grip and normal function returns to the body.

It's too bad because the price is great. I don't know if the problem has ever been corrected. I've heard of battery drain problems but haven't experienced that.

I'm saving for the Canon grip. I won't return the Pixel grips because the high cost of return shipping and it's not clear the company would return my money.

It's the last time I buy outside of the USA and Canada.
