Well, we finally find out whether Canon either can or cares to match Exmor and whether to live with a mish-mash of older Canon bodies plus new adapted Sony or go Nikon for some....

Hopefully it's not just the 7D2 sensor made FF size.
...

Yes, that's the million dollar question, isn't it?

I don't know if anyone else has suggested it and would solve this with a L-battery grip if it as produced. In this way you have all the nessarry mechanical and electrical connection points in place. The buttons on the vertical part of the grip are moved to the other side and an horizontal part is added with also controls on the top. The ports that are present have to be routed internally to and other location on the L-battery grip.

It is an U-shape contraption with the left had side detachable and for cameras who keep the battery in place it L-shaped.

Well if there is a viable market for such a thing then I can't see why it wouldn't have been made already.

I like the "left grip" idea. It could be done far more economically than a left hand camera. A lot of things you can work around or fumble through, but if you only have use of the left hand, you NEED! a shutter button on the left.

A cable release lets you have a shutter button anywhere you want.

Ok, she's left handed and can't use her right arm/hand.

But how many of us shoot with a DSLR using only one hand?

Could you pick up your 5D3 with 300/2.8 and use it with only your right hand?

How do you zoom the lens when you're holding the camera?

And so on.

I don't mean to pick on a disabled person but I'm sorry, I just don't feel that this is a genuine issue here and that someone is just looking for clicks or 15 seconds of fame.

Your lack of empathy and understanding is astounding.  Simply astounding.

In other news, have you ever seen the one-armed college/(pro?) baseball pitcher in action?  You would obviously be dumbfounded at what someone with talent and determination can do in order to accomplish and perform the things they wish to do, despite their limitations and your ignorant negativity.
...

Well it would seem that if she has enough talent and determination then the lack of Canon's support for left handed people won't get in her way, will it?

Definitely on the gimmick list is in-camera hdr as this is done better in real post with dedicated software.
By that logic, in-camera JPG conversion is also a 'gimmick'.  ;)

No, because you cannot "easily substitute" the reduction in card space and jpeg makes sense if you need sooc pictures asap.

But the general point is - I am in absolute agreement with you on this - that one's personal wishes are immaterial for Canon's big market and it's not really possible to separate "real features" and "gimmicks". Fortunately (unlike Sonikon) Canon doesn't concentrate on spec comparisons, i.e. their aim isn't to have the longest feature list.

Oh I don't know about that. Do you have some examples?

I fear that no one has pointed out the 'trap' of shooting LS's with a long zoom.
The 1st issue is that, the more air (distance) between camera and subject - especially out in the wide open LS type places, the greater the distortion from air / dust / environment.

I fear that you haven't used a long zoom for LS often enough to know whether or not to fear this problem.

As for poor dynamic range: For the a lot of people in the targeted audience (landscape and studio) ~11.5ev is fine, you only need higher dr if you cannot bracket and/or shoot movement. Otherwise higher dr is nice to have, but not essential - or there wouldn't be any Canon shooters left even now.

You obviously dont speak for the majority. The current 36MP Sony sensor also in the Nikon D800 is 14ev and in cinematography / video 14ev is still not enough. Plenty of situations in landscape where more DR would be useful particularly in strong sun situations with deep shade.

Nope.  He speaks or the MAJORITY.  Hence why Canon leads the market.

I know people that have bought Canon for gimmick features (WiFi) and people that have bought Nikon for IQ.

Don't know anyone personally that has recently bought Canon for IQ purposes.

The thing is, gimmicks will sell to the masses, more than IQ.

But concerning clean shadows: Your wish is granted instantly, because the 1dx/6d sensors are a *big* leap from the 5d2. I recently shot with a 5d2 from a friend of mine and was stunned how much banding it produced after postprocessing operations that I do with the 6d raw files all the time.

The 5D3 was released after the 1DX so just because a camera is a "later release" from Canon means nothing. The problem was the 5D3's sensor is more like they took the 5D2 sensor and just put it back in the oven to reheat. Will  Canon do that again? Wait and see.

What do you guys prefer? The IQ of a prime is hard to beat, but the flexibility of a zoom seems more practical, especially since it's harder to zoom in and out w/ just your feet in the wilderness. Is the IQ of a wideangle prime worth it vs the flexibility of a wideangle zoom?

The only good wide angle primes are from Zeiss/Leica. (I'm deliberately ignoring the TS/E lenses from Canon for various reasons.) All good wide angle primes are manual focus.

So once you accept that, you may as well get a zoom like the 16-35/f4.

How hard can it possibly be to use a non -Bayer pixel pattern like Fuji does?  My understanding is Fuji just made the pixel pattern less simple than the little repeating 4-pixel blocks in a Bayer pattern that give us this problem with screen doors/fabric/etc., and this makes the low pass filter unnecessary. 

It seems fairly straightforward and not subject to any patent issues vs. Fuji. How could anyone patent "any pattern in the world other than Bayer"?

Note that as a result of using a non-Bayer array, Fuji's cameras have more limited 3rd party support for raw image development than do Bayer array sensors.

That is a good point. I had not thought of it. 

HOWEVER, Fuji is Fuji.  Canon is Canon. Adobe always does the quickest updates for Canon cameras.

Probably because each Canon camera is so much like the previous one in terms of IQ, there is very little for Adobe to tune!

There are an awful lot of people here who did exactly what I laid out, owned a crop camera and then got a ff one and hardly touched the crop camera again afterwards, virtually every one of them will say they see the difference in their images, if you can't in yours then that is up to you.

The only benefit of APS-C over FF is increased pixel density.

If Canon bring out a FF DSLR with similar pixel density to the 7D2, I wouldn't be surprised to see a bunch of folks sell  their (FF, APS-C) combo and buy a single new camera. The only consideration then would be if the new camera has enough FPS.

EOS Bodies / Re: Global Shutter Coming to Canon DSLRs? [CR1]
« on: January 22, 2015, 05:02:18 PM »
What's the point of having 30fps when you have video shot at 30fps?  Doesn't the 1DC cover this?  Or is this basically what the mirrorless cameras have, just faster? they have very fast frame bursts..  slightly confused?

Video has two disadvantages.

its resolution is usually less than still frame modes/cameras

Except that resolution is measured differently.

For example, when 1080p is played back, there are 2,073,600 pixels but they're a combination of RGB.

Your 20MP DSLR counts each R, G and B (and G ;) as individual pixels (except if you're Foveon) and does some fancy math to get 20,000,000 combinations of RGB.

If they counted video pixels like they do DSLR pixels, 1080p would be 8MP and 4k would be 33MP.
