But there ought to be some room for a EF-S telephoto lens with the inherent advantages of weight reduction from the shortcuts the lensmakers can take when designing for a smaller image circle. I am almost certain there will be something like this coming for the M-mount, and I think a conversion to EF-S would be easy, as the glass is for the same sensor size, and the difference is in the mount and flange distance as I understand it.

Anyways, a 300mm f2.8 for EF-S, at the weight as the 300 f4 or less? They could get away with a weather sealed plastic build (something like the 17-55 2.8 ) if done properly, and the price is right. (Yes, dreaming now, but...)  :)

Smell that?  It's sweet-and-sour scent of optical physics and lens design waking you from your dream...  :P

A telephoto lens design places the 'virtual' aperture at or near the front element.  So, a 300/2.8 lens is going to need at least a ~107mm diameter front element to fill that aperture with light. That front element is going to be big and heavy, and need a strong frame to support it.  A smaller image circle would mean a slight reduction in some of the internal elements, but won't really make the lens smaller (or cheaper). 

There's a reason we don't see EF-S telephoto lenses (except one zoom that actually starts in the normal range and has a variable aperture, meaning a different lens design) - there's just no real advantage to a smaller image circle at long focal lengths.

The 7D is a very good camera, and will remain so after the 7DII is released (likely at a much higher price).  Now is a great time to pick up a used 7D.

Simple as that. I think that is hard to deny even for the biggest 5D3 hater.

You'd think so, especially from someone who claimed the AF was the only improvement from the 5DII. But I guess now even that's not a real improvement....

For the 5DC, 7D and rebel-crowd, I'm sure the 5D3 is a great upgrade. :)

...and for the 5DII crowd who shoot things that move.  ;)

You're telling me that using a 5DIII with the same shutter speed and aperture as a 5DII will result in better photos of "action"?? I'd like to know how you work that magic. Do things automatically go slower when they sense a 5DIII is taking a photo of them?

Thanks, now I understand you.  Your dislike of the 5DIII (or maybe Canon, in general) has completely eliminated any objectivity you may have had.  This assertion is even more ludicrous that others you've made.   If you honestly believe that the better AF system of the 5DIII cannot yield better images of moving subjects than the 5DII, then I feel comfortable dismissing your arguments on the subject as biased to the point of irrelevance.

I've decided to exchange the body for a new one...

That's what I'd do in your situation...

@ anthony11 - pick many nits?

It's 6 fps.  All the Canon fps specs state 'max' or 'approx' so maybe they are all lies?

Maybe you don't shoot in the rain for fear of having to shout, "I'm melting...what a world."   :P

Do you have trouble seeing the AF points on your 5DIII?  Maybe you need to visit an ophthalmologist. They were perfectly visible to me.

Dual CF would be nice.  But two is still better than one.

So it does have better metering, right?  What's your point there?

"Vaguebook?"  Make up words much?  Try using one...

The second multicontroller is on the battery grip, also known as a vertical grip or portrait grip, officially the the BG-E11. It attaches to the bottom of the camera, providing controls for portrait orientation, and the second multicontroller makes AF point selection a lot easier when shooting vertically.  The battery grip for the 5DIII is the first battery grip to offer that feature, also found on the integrated vertical controls on the 1D X.  Sorry I didn't make that clear.

So, we agree that the 5DIII doesn't offer significantly better IQ than the 5DII, and based on the long list of your responses, there do seem to be many other changes besides just AF.  Just because you don't find those changes beneficial doesn't mean others feel the same - as noted above, the 5DIII gets high marks from a majority.

Yes, the LP-E4 battery (for the 1DIV, 1DsIII, maybe others) works fine in the 1D X. 

There's a 'minor' issue with the respective chargers, though - the old charger (that came with the 1DIV) can only charge the new battery (LP-E4N for the 1D X) to about 90% capacity.

Don't be so fixed on megapixels as being the only problem that needs attention.

What needs addressing is IQ. A combination of more megapixels and improvements in noise, DR, etc, is what is sought.

In essence, this is what the entire Canon community (apart from a few deniers such as yourself) seem to be saying - a new camera that costs $800-$900 more but my pictures are pretty much the same as before. WTF?

First, what makes you think I'm 'fixed on megapixels'?? I'm quite happy with the 18 MP that I have. Also, in case it escaped your notice, this rumor thread is about a high MP Canon guarantee of better IQ, and as I alluded to earlier, high MP doesn't mean 'better'.

Second, I do take issue with your statements that Canon's current sensors are somehow 'bad'.  I'm not saying they're the best on the market, they're not...but implying they're sub-par is rather disingenuous.

Third, who the heck is 'the entire Canon community'?  I can only assume you're referring to the tiny minority of people here bitching about Canon's 'terribly low DR' and 'horrible, shot-destroying pattern noise.'  The 'Canon community' and in fact, the dSLR-buying community at large seems to be quite pleased with the 5DIII, and with Canon in general.  Have a look at's Top Rated dSLRs (note - top rated by customer reviews, not top selling, although Canon owns the top of that list, too).  The 5DIII tops the Top Rated list, and Canon holds the entire top 15.  Then we see Sony...but where's Nikon?  One Nikon camera in the top 20, a total of 5 in the top 40.  And the D800?  Based on customer feedback, it's not even in the Top 100 at all (the D4 and D700 are in the top 50, but only barely).  So I'd have to say WTF to your claim that 'the entire Canon community' is dissatisfied with the 5DIII.  A 'community' of about ten (excuse me, now about nine) naysayers here such as yourself, perhaps.

Probably the camera.  But...(and, maybe I missed it) what were you focusing on as a target?

If they do have some much better sensors coming out...

Except...that's a pretty decent-sized IF.  More MP, yes, I'm sure that's coming...but I'd be surprised if that's what you mean by 'better'...

The warm tone can be easily removed by adjusting the WB in post.  I wouldn't stack another filter to get there...

He's talking about register/recall shooting function, see p.344 in your manual.

I don't use that, personally. But...I do use the C# settings (I have a few C1-C3 'groups' of them, e.g., people, outdoors, etc., saved on an old CF card). I have the M.Fn button set to directly select the C# settings.

Is everybody sleeping in this morning? 

Can't speak for everyone, but "Nemo" found us and we were finishing digging out from 30" of snowfall during the New England blizzard...   ;)

The 5D Mark III is far from being "inadequate."  It's more than adequate for most photographers. If you need more than what the 5D3 can deliver, you should consider medium format cameras.


I'm sure there are some people for whom one single feature is so critical that it's the only one that matters, but for most, it's important to consider the whole camera...

The TS-E 90mm is the lens for small product photography.

See the coin examples here: which align with what you're trying to do.

So Canon did all of this yet there are stories already about a quick replacement of the 5D3? Well, that tells you how important that list of "improvements" that you listed is, doesn't it?

It tells me nothing. There have been 'stories' of a new 100-400L for what...7-8 years?  There have even been at least two patents. Where's the lens? Stories.

As for a 5DIII 'replacement', I'd say BS and wishful thinking.  Many of the people clamoring for a high MP camera from Canon don't want to pay the price for a 1-series body, and from such dreams, rumors are born.

Let me put this another way. If I pick up and use a 5D Mark III, what am I going to notice as being significantly better aside from the AF? Nothing. What do I see as being better when I look at the images on my computer? Nothing.

So $800 or $900 more for improved AF.

Sorry, I completely disagree with that conclusion.  With a few notable (and *cough* vociferous) minority exceptions, the consensus was that the sensor-based IQ of the 5DII was excellent - it wasn't broke, and Canon didn't fix it.  Because of that excellent IQ, many people used the 5DII for tasks for which it's not ideal.  There's a reason I and a whole bunch of other people had both a 5DII and a 7D.  What Canon did with the 5DIII was, IMO, huge.  They took a camera with already excellent IQ, and improved substantially on the overall performance. 

For 5DII tripod-only, ISO 100 shooters, I can see the incremental nature of the upgrade. But if that's you, the answer is simple - keep your 5DII.

You state, "If I pick up and use a 5D Mark III...," which I take to mean you haven't.

After a couple years shooting a 7D and a 5DII, when I tried out a 5DIII what I immediately noticed was that it felt 'fast'. For example, the difference between the ~200 ms shutter lag of the 5DII and the ~100 ms lag of the 5DIII is very apparent.  My overall impression of the 5DIII is that using it feels like using a 7D from a performance standpoint, and it delivers the IQ of the 5DII - that's a powerful combination, and whereas the 5DII was liked (almost exclusively) for its IQ, the 5DIII is, IMO, the best all-around dSLR on the market.
