The thing I'm really interested in is whether Canon has made any improvements in DR.

If they can match the A7r and D810, then Canon will have a very competitive body.

If they can't, and simply scaled up the 7D2 sensor, then the A9 (and rumoured A7rII - currently a SR4 rumour on SonyAlphaRumours) will be a lot more attractive to many potential buyers of a 50+MP sensor.

If you don't get it, then don't get it. It's that simple.

It will be better than the native 20MP sensor. By downsizing, you get rid of most of the artifacts, colour fringing and other aberrations associated with a full-resolution (whether 'full' is 20MP or 53MP) Bayer-sensor image.

That's rather hopeful - it has been proven previously on this forum that sraw and mraw are poor substitutes for using the original image and properly downsampling it in post

Not as good as properly downsampling it.

But still better than a native lower-resolution sensor.

And that's only if Canon continues with the same downsampling algorithm for mRAW and sRAW. A Phase One-style pixel binning technique produces a file every bit as good as one properly downsampled in post-processing.

Yep, it'd be great if Canon used a proper pixel binning technique. They haven't shown over the past 5 years or so any inclination to change though

Why in the heck do we need a 53 MP camera.

The latest in a long-running series. Historians date this back to around 2005, when Mickymouse (suspected of being an alias) first complained when he upgraded from 2 MP to a massively wasteful 3.2 MP! LINK (external link)

Rather amazingly, my reply to Mickeymouse could, with just a few amendments, form the basis of a reply to this post.


Plus ca change.....

LOL that was fun reading
around 2005 i was struggling to up-sample a heavily cropped 4.3mp to 6MP which was the acceptable lowest commercial standard at the time and still is according alamy
now i am at 18mp and back where i started with super macro ,struggling to shoot a subject at 1.5mm hand held in the field and fill the frame in post

Canon needs a high resolution answer to Nikon and Sony, but if they provide it, then it won't be a great general purpose camera. I'm not sure if mraw or sraw is a good answer. The D810 can shoot small, but it only outputs 12 bit raw files. And is there a hit on the dynamic range as well? That's why the D750 makes sense to me in Nikon's lineup.

It would be ideal if Canon would make the 5D IV in two or three versions. I like that Sony developed an a7, a7R, and a7S to better zero-in on each photographer's resolution and AF needs.

That would make more sense to me. Even 2 versions would help. Have a 25MP FF with all the latest bells & whistles & high ISO, etc., and then those same features with a 53MP camera for the people like Shadowblade who need that for the large printouts.

Here's my take after following all the high MP talk and DR Mafia beat downs across various forums on the internet:

-People **** and moan about Canon sensors being old tech, are garbage and their lack of DR. Also complain they dont offer a high MP body to compete with Nikon/Sony.

-Rumors say that Canon will introduce a high MP body, possibly with sensors jointly developed between themselves and Sony.

-People **** about the rumored 53MP being too high and that they hope Canon stays in the sensor business to maintain competition.

I see it only goes up to native ISO 6400.I bet it's amazing at ISO 100 but noisy as sin at 6400.

I'm guessing it produces great quality all the way to ISO 3200 or so, then starts to taper off - hence, they set the cutoff at 6400. Also, Canon being Canon, they'd want to avoid treading on the toes of their own action-oriented 5D4 and 1Dx2...

Since the 50MP sensor will be only slightly lower in res than the 7DII equiv on FF do not expect miracles at ISo6400, just take a look at a Nikon D800 RAW at ISO6400... ;) but what it will give you is the possibility to resize that file down to 20MP and it will clean up quite alot... even more if you do it in stages with some light NR between.

So do we need a 50MP camera... well some of us do, some of us don't. It is funny, we have a 1Dx doing 12fps, do we question it... DO WE NEED 12fps? :|

I only question the diffraction limit on such a small sensor with so many pickles? Yes the micro mirrors help but that is alot of pickles. I am sure however as a landscape or studio camera... with a T&S lens at lower ISOs it will be great!
