I lifted shadows from files taken with an Exmor sensor camera and frankly, I didn't like the results. They looked flat like half baked HDR images. So, I ended up putting in darker tones back to make it look "normal" again. I did shadow lifting at approximately the same amount from files of the 5D Mark III and I didn't see any ill effect. And yes, the images look pretty much the same. I am not denying the presence of better shadow details of the Exmor files but I didn't see the advantage of that in my workflow. Again, under real life shooting conditions. BTW, I got the impression that the files of the 5D Mark III can tolerate highlights a tad better than those of the other camera. Take your poison. ...Show more →
The key is "in your workflow". If you don't shot high dynamic range scenes, then obviously you won't need the capabilities of a sensor that provides high dynamic range abilities. Your point about "real world" conditions again needs to be prefixed by your shooting conditions. I shoot in "real world" conditions and I constantly run up against not having enough dynamic range in my sensor so I constantly need to tame the dynamic range using techniques such ad GND filters or merging multiple exposed images...neither technique is without it issues and problems.

Well, the Sony A7r is available and is up for "grab". This is the first camera that you can use your Canon lenses with without having to worry about the shortcoming of DR in your files. Until another sensor comes about with a DR of 16 or so then we will start our whining again .

I'm getting a little tired of people calling it whining every time we talk about the abilities of other cameras than Canon on this forum. Just seems like such Immaturity by people jumping in with such statements. Can't we just discuss the abilities of other cameras and the needs of other photographers and Joshua, I suggest that if dynamic range is of no interest to you, just stop visiting the threads on such topics.

But Harry, please re-read the title of this thread. We didn't discuss any DR that we know of until somebody brought it up later. Am I mistaken? I am not mocking you at all and I stressed the word "our", too. Did you notice that?

Ok what's this image supposed to prove. Please don't tell me only a 14 stop sensor could have taken this photo?
Any cam can takes these images but not all data can be retained during I/O processes so the final results won't be the same. Some mixes with junks, some has less junks. The closer to simulate to our eyes the better recorder, and latest sensor is still in long way compared to human vision border.

Matter of fact, I don't mind to trade everything I have for 4MP, 24 stops DR sensor so I can shoot 24 hrs a day without any (lights vs h/w) constraints. Who said DR is only good for landscape application. Imo, the better DR the smoother IQ you can get from a cam and this IQ can be easily seen from most tricky lights shots between cams.
mttran,
What lens is this shot with? There is some pretty strong vignetting in the corners which I have seen with A7R sky containing images. I'm wondering to what extent this is unique to the lens or is more characteristic of the camera/lens combination? I know that some lenses like the Zeiss 21/2.8 have vignetting, but its much more gradual effect.

Of course I didn't compared with a7r using first electronic curtain or mlu, I can't. But I compared with 10seconds or more same shots and I can say there is no less sharpness when using shutter time where vibrations normally show. For me this is a non problem. I will redo the test on far objects at hundred meters but actually I didn't see any vibration effects.

Sorry, it said M35/2II and I don't know what does that mean.
Michael, I believe that image was taken using a Leica-M 35mm f/2.0 Version II. In other words, it was not taken with a Canon camera and nor with a Canon lens. No offense and I am not telling you not what to do but if you don't get the permission from the photographer, posting a link of images is a practice that is frowned upon; not quite kosher, in other words. If you hover the cursor on the image you posted, your copyright info shows up.
FYI, the FM Alternative Board has tons, literally tons of images taken with the Sony A7/A7r with a huge variety of lenses from vintage rangefinder to modern lenses, vintage SLR lenses to modern DSLR lenses, including Canon EF lenses. I am sure you know that, but just in case...

Many of the 'anti-Canon extremists' he goes after have been using Canon for 5, 10, 20, 25 years. But yes, in his mind they are all anti-Canon, out to get Canon extremists.

For all the rhetoric I can't tell jack from all the images posted. I'd have to be correcting some RAW files shot in harsh sunlight before I'd believe the claimed Sony superiority. I'm feeling cranky after having three days of shooting in garbage light - midday athletics. You know, I want to see it for myself, that's all. That being said, the A7 isn't a replacement for the 5D3 in my general shooting.

Totally understandable. I was in same boat, and using A7R for more than a week now, I'm really amazed by the superiority of sony sensors. You can find some a7r raws on the web and test by yourself. But developing your own raw is just jaw dropping after so many years using Canon sensors. Their next pro body will really have to be a big jump in sensor tech to make me come back to Canon bodies ... And god, I love 1 series bodies, but sony sensors are too far better for me, plain and simple. Sure A7R have its drawbacks and limitations but the files are just wow ...

Cheers. I'd want to play with RAW images I have shot and mangled. Totally agree on Canon really needing to stop playing games at risk of pissing off huge amounts of punters.

The only posters I've seen him/her "go after" are the ones spouting the "Canon is doomed hyperbole". I don't think years of use has anything to do with it.

Over 100 000 hits of this post about a non-Canon based camera....unthinkable a few years ago when I was criticizing here that Canon has no high MP/high DR sensor present in their cameras compared to Nikon's D800(E). Guess a lot of people are missing new sensor technology in Canon's camera line. Canon better gets moving....quickly with an affordable 5D series camera equipped with competitive FF sensor.
A friend of mine received last week his A7 camera and showed it to me - I can only say: amazing. A bit small in my hands and a bit cumbersome menu buttons, but the IQ.....simply amazing. And this was not even the A7R.
