For Me:
1. Larger buffer. I shoot Raw and hate to switch to Jpeg to keep up with action.
2. Improved GPS.  Current GPS takes some time to lock in.
3. Removal of AA filter
4. Faster Memory Card support.
5. Tilt screen.
6. Touch Screen

I totally don't get the anti-AA filter fetish -- I'd much rather have microscopic softness than moiré.  Unacceptable softness is much more likely to be caused by poor AF or DoF than the AA filter.  For landscape I can almost see removing the AA filter because AF and DoF error can usually be removed by proper technique; even there, though, unless you're printing YUGE you're not going to notice slight softness on 20+ MP images.  And, BTW, the 7D-series is marketed more for action than landscape

As an aside, I'd love to see side-by-side shots of 5DS and 5DSr of the same scene for comparison.

I'm with you. I strongly suspect the anti-AA filter fetish is one of those Internet forum infatuations that is driven by a desire to be cool and sophisticated. Somebody comes up with the idea and everybody jumps on it based on some assumptions that aren't necessarily reflected in real world use.

It is interesting to see how the 7D2 does handle moire better than competing bodies, but apparently no-one cares and the vast majority of images do not have moire problems.

And then we have the principle that extremely high resolution sensors don't suffer from moire because it has enough resolution to out resolve the patterns that are a problem at lower resolution.
With the right fabric at the right distance there will always be moire at some point, but it would be true to say that a 40MP sensor will not suffer the same level of moire as a 20MP sensor with the same framing.

Here's a thought experiment about flip screens. How would a flip-out screen fit on the 7DIII, if implemented? I see the challenge not just in the weathersealing/durability as Canon have always claimed, but in the displacement of no less than 5 buttons on the left hand side. They could make the screen up/down tilt only, such as the Nikon D850.

I think they would have to either rearrange the buttons to be more like the 6D (and killing the control continuity with the 5D line) Or they would need to create a VERY thin bezel on the flippy screen, and put the buttons above and below the hinge mechanism on the left. I also see space to move the trash button below the dial.



I think the can put the 5 buttons part of the interface that you will see in the tilt screen. The dimension will remain more or less the same. But users will not have the feel of the button anymore instead get used to the touch screen. :D

Keep in  mind that there are two classes of buttons... you have the buttons and dials that you use when shooting, that you use by feel in "the excitement of the moment", and you don't want to do anything to obstruct those buttons....

You have the other class of buttons, the ones that you use when you are not shooting.... to review pictures, skip through menus, etc.... those buttons could easily be relocated or replaced with touch screen functionality.

2. Spot metering linked to AF points.

Already present on the 80D, so it would be very surprising if it was omitted on the 7D3.

Hi Grekko,

I have a very bad habit of forgetting about posts I've comented on and I forget to come back to them hence the late reply!

The original post (not by you) that I replyed to was specifically talking about Spot metering linked to AF points.
I don't think the 80D or 7D2 has that from the table (I don't have a either so happy to be corrected!)

What I didn't realise was that metering is linked in other modes though, really cool and as you say that functionality won't go back the way!

Regards

Yeah, I'm with you.  Moiré will totally ruin a shot; softness you'll never see, won't.  Plus, post-processing sharpening will completely eliminate the softness 99.999% of the time, and provide an acceptable result to most human beings 100% of the time; but if you get hit with moiré on something that matters, that you don't catch in the moment, you're screwed.

Plus, very few people really need 20+ megapixel files in the finished product.  Once you reduce it, any softness will be gone, but you'll still be stuck with moiré.

Interesting that everyone seems locked in on the 24 mp.  I hope for at least that and possible a little more (up to 30 mp).  Reason being, with bird or wildlife photography I will take all the MPs and cropping/reach I can get.  I use the 5DSR and appreciate the ability to crop images and still maintain resolution of feathers, eye detail, etc. 

It would be great to have the equivalent resolution (considering crop sensor) with all the additional reach, speed, focusing ability, etc.  If I get that as well as better low light handling (better handling up to 4-5000 iso) and dynamic range (1-1.5 stops). 

Not sure if I will get all of that, but it would drastically improve all of the deficiencies I deal with in the 5DSR today and keep most of the benefits of the higher resolution.

Yes, but the gear-heads want a camera with the MOST MPs, the MOST fps, the MOST DR, the MOST sharpness.  Otherwise they feel that the camera is crippled.  Doesn't matter if too much sharpness is actually a negative in MOST photographs.

My wish list includes

- Low light/High ISO better than 1Dx M2 by 1-2 stops


Anyone else care to share their "realistic" thoughts on what you hope to see in the 7D M3.
Ha-ha-ha! With a crop sensor, too! Chortle!

good point.  Perhaps 1-2 stops better than current?

Not going to happen

Readout noise is sufficently low now that I'd challenge anyone to notice the difference between current state of the art and absolute perfection in that regard.

One way forward is to improve quantum efficiency.

Raw sensor QE with micro-lenses is around 70% peak at the moment, less in red and blue.  Add in the bayer matrix and we're down to about 25%.

So you need to change the matrix to an on chip dichroric style prism microlens array (not yet invented), or go with three sensors and a BIG interference filter based beam spitter to efficently split the colours and you'd need back illumination to get the raw quantum efficiny of the sensors up to ~90% across the entire optical band.

Otherwise you're stuck at around 25% QE.

here's an excellent write up done in the era of the 5DII and 50D, things have improved a little since then: http://www.astrosurf.com/buil/50d/test.htm

I strongly suspect that Canon has surveyed photographers and found that most pros will say "don't mess with my buttons" as people who use their cameras daily are creatures of habit and don't take kindly to having the cheese moved around.

Can someone tell microsoft please!

Wouldn't do any good to tell them, they don't listen.

For routine use, not ultra high MP, the AA filter does not hurt much, if at all, and can save problems.
