Re: 75MP+ Pro DSLR: for architecture and landscape?
In reply to Canonero, Jul 22, 2013

I didn't bother to do the calculations. My point was that this is a specialist camera. Or, that the old fogies like me need to update their 3 year old mid-level computers to genuine muscle machines...

From: Photography Bay...received word yesterday from a reliable source that a pre-production high resolution Canon DSLR is currently undergoing field testing. The camera is a pro-sized body like the 1D X. The resolution of the sensor is greater than 75MP.

Of course, Canon has tested cameras and technologies before that never made it to the market. And, this seems like such a massive jump in resolution from what is currently on the market.

The Canon EOS 1S has been in the rumor mill for some time as a high resolution pro DSLR, albeit prior rumored specs of 47MP-ish. Just because Canon is testing cameras with 75MP+ sensors doesn’t mean that a 47MP sensor won’t end up in the final model.

The rumour doesn't ring true. What jars is not the pixel count, but the idea that it has a new super resolution rear LCD - I think Canon's practice would be to put this new sensor in the stock 1D X body, they didn't enhance the 1D C with any special LCD or other gadgets.

Though, one thought, if they use the twin pixel architecture like the 70D then a 37.5MP sensor would end up with 75MP. The sensor plane PDAF could be pretty useful in a studio cam used for tethered shooting.

I would not think a Canon "rep" (aka salesman) would know what Canon Japan has inside their R&D shelter.

Those that ONLY shoot landscape want 75Mp. Why not? if you don´t want, don´t buy it, you has several cameras from cameras with less megapixels. Don´t speak by other photographers that need and want (like me) this camera. On the other hand with this camera yo can crop heavily if you need, which is fantastic. Think on all posibilities.

I think Marino is just being sarcastic here... Canon fanboys have been doing tests and proving how 36MP has no practical use over 22MP.. some even suggest that 36MP has negative impact to overall image quality.

Now Canon is going 75MP.. what say will they?

Probably the same thing the Nikon crowd said when they finally got FF and more than 12 MP :-).

Actually that concept might not be far off.

If Canon pre-combined 4 pixels into one full color pixel, the resulting file size would be similar to the current 18-22 that Canon seems to think is optimal.

I doubt that Canon would be willing to associate their name with the color artifacts that would be incurred by such a method.

I just hope the new sensor has much better DR

Well, it would have 1 stop more image DR, even with the same technology.

Canon's bottleneck to DR is pixel DR, so the only way to get more DR is to have more pixels.  A 1MP FF Canon DSLR would have horrendous image DR.

Is that a joke?  Lenses do not resolve sensors; there is no signal coming from the sensor.

The job of a sensor is to resolve the lens, and any good lens at its sweet spot will not be properly resolved by a FF 75MP sensor.  A lens is not properly resolved until the resulting pixel contrast is low, and to properly resolve the red and blue channels independently takes 4x as many pixels as it takes to resolve a B&W pattern.

Exactly, how would Canon using in camera Bayer demosaicing be any different than what a JPG engine does (except no lossy compression or 8 bit file size) or what Nikon does when they output to a demosaiced TIFF file?

I have no idea why you said this (the grammar is confusing), but hopefully I will address whatever it was that you said.

If you take each (non-overlapping) 2x2 tile from a Bayer capture, and turn that data into 1 output pixel, what you get is quite inferior to what you would have had if you had 1/4 as many full-RGB pixels.  There will be 1/2-pixel color shifts in the red and blue channels, because the center of green is in the center of the output pixel, but the center of red and blue are offset at diagonals.  So, high-contrast edges will have half-pixel red and blue color shifts.

The only way to avoid this is to do a normal demosaicing first, and then downsample or bin the image (but binning leads to aliasing, which can be avoided with a proper downsampling).  In this latter method, there is no such thing as an exclusive 2x2 tile; such a concept does not play a role in quality demosaicing.

I have a camera with sensor of that density
In reply to mailman88, Jul 23, 2013

I have a Nikon V1 that has the density of 73MP if sensor were FF size. I don't think many people used to the IQ of the current crop of FF sensors will like that at full res. I think the D800's at 36MP = 16MP in APS-C is about the limit I'd go for resolution. I'm not talking about noise or DR or anything, it's the looks of the image at full res that bothers me. Of course, for internet posting it's pretty decent, but then why would one need so many pixels?

BS.  Some people say that and they will probably stick to their opinion.  I and others here want a high mp camera, but I would still use my 1DX for 80% of my shooting.

Yes Canon lenses will work, but very few will stand up to the scrutiny of the such high resolution. That is what Nikon shooters have discovered.

I remember this stupids questions when rumors of the 1DsII.

Which is why lenses like the 15-35, 24-70 and 70-200 have since been upgraded.

75Mp is more or less the same pixel density that Olympus m43, what is the problem??

The [problem is that the Olympus m43 does not place nearly the same demands on teh lens that a FF sensor does.

Why would a Canon rep have any inside knowledge of future products ?

If she didn't know, then she would not have offered such a definitive answer to the question we posed.

Since the Nokia 808 41mp camera has the best image quality of all smartphones I don't see any reason why Canon would not come out with a high mp FF DSLR in the future.

I agree.
