For those that believe they can reproduce similar latitude to the Image discussed in this thread from single exposures from a Canon Sensor, I would be hugely interested to see some evidence, and I mean this in a positive sense, I would like to know just what I'm continuing to do wrong with my Canon gear that in a single exposure generally doesn't produce as much latitude as a single exposure on either the D800 (owned one of these as well) or the a7r.
I should have clicked the link and read the description sooner. You have your evidence in the screenshot I just posted above. He used +0.65exp and +100 shadows. In my shot I used +1exp and +80 shadows. If I put in his numbers I get pretty much the same result. Just using the exp slider, either combination equates to roughly +2.5ev.He is praising Sony for, and we are debating, an image that could have been produced with a single frame from any modern camera including the just discontinued original 7D.
This is very much like the recent D750 review where the reviewer acted as if his wedding shots with +1 and +2ev pushes could not have been done on a 5D3 because in a +5ev bedroom shot the 5D3 didn't do well.
This just goes to show how difficult it is to produce a real world sample that lies between Canon's limit and Sony's limit. Erez's example and the wedding shots in the D750 review are within Canon's range. Jrista's interior shot, while showing that the Sony has more range, was still actually outside of the Sony's range.
Look, Sony FF Exmor sensors at base ISO can go to +5ev with hardly any NR and produce decent results. Basically your shadow detail can be pitch black in the original image and still be recoverable. No one denies this is impressive or occasionally useful.
Canon sensors cannot do this. But if you can make out the shadow detail, as you can in both my original and in his, then you can recover and use it with a little NR. Basically you can recover detail that is -2.5 to -3ev below where it should be. Any more then that and the noise is too great and the detail is too little / too rough.
But that's quite a bit, especially if you ETTR and remember that you've got 0.5ev on the highlight side. You are not going to run into very many situations where the scene is just beyond a single Canon frame, but safely within a single Sony frame.
