• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

Interview About the EOS 5Ds & EOS 5Ds R with Mike Burnhill

The thing is you can get an adapted Sony that will offer a lot more dynamic range and only modestly less resolution for a ton less money.

DR difference = 21%

Resolution difference = 38%

Hmmm....

Well, you can also look at it this way:
21% is the difference in the number of stops. However, because DR is an exponential function, where each stop doubles the dynamic range, a difference of 2 stops essentially means 400% wider DR :).

A resolution increase from 36 to 50 mp, on the other hand, although it gives you 38% more pixels total, is only ~17% (=sqrt(1.38) ) increase in each dimension, not a whole lot.

That may be true in terms of the light energy striking the sensor, but it's not how the human eye interprets it. Most people would be hard pressed to even detect a 1 stop DR difference on the shadow side with two prints side by side. (Seriously.)

Well, well and yet then what of those who keep saying that Exmor is not worth it because, in a few cases, you give up 1/4 to 1/2 stop DR at high ISO to get the extra 3 stops at low ISO. ;D

They are being silly.

For the record even though I threw those percentages at you, I imagine the resolution difference between the A7r and new 50 MP 5D bodies will be close to inconsequential.

I'm glad they're focusing more on photography again and less on video for the 5Ds/5DSr.


I agree with you.
That makes 3 of us. Interesting interview and I'm fine with the DR in the current bodies, so I think the 5DsR is on my shopping list as a 5DIII replacement. I love that my L-plates and everything will still work.


+100 for me too , Dear Mr. Click
Canon 5DsR will be on my bag ASAP, when they on US. market on this June 2015 = $ 3899 + Canon Battery Grip BG-E 11 = $ 250 US Dollars.+ Kirk L. Plate.
Plus My New Toy EOS-M MK III too.
Have a great Sunday, Sir.

Don't forget that the EF 400mm f/4 DO IS II @ $7k isn't an L lens ;)
