there are, um, three sides to the coin here. which means it's not a coin at all, but whatever.
first, there are the internet trollers who just spit out shit about canon's sensors ad nauseum simply because that's what they do. these folks are usually identified by their photographs of things like brick walls and other things you'd never actually bother printing out and hanging on your wall.
second, there are the actual photographers who need the ability to push shadows like this. this is not 100% of photographers, but certain folks like chez who just posted would definitely take advantage of better DR because they have a real, identifiable application of the technology. folks who are using tripods and iso 100 and would get the most out of the sensor, you know?
third, there are the people who have a low-level anxiety about whether or not this "lack of dynamic range" is actually hindering their photography. i suspect this is the majority of photographers, myself included. do i see instances where i would benefit from being able to push shadows a bit more with clean results? absolutely. would i take the extra DR? absolutely. is it a chronic issue? no.
oh, i guess there are four groups. the fourth group is photographers who are just out there working and couldn't care less.
i think there is also something else that needs to be considered here: let's not forsake the way that light and dark can have an effect on emotion, on positive and negative space, on composition, on balance, on silhouette, on atmosphere, and so on. you know how everybody makes fun of HDR because it looks like shit 99% of the time? well, all the same people laughing at HDR are here begging for a sensor that allows them to basically make HDR shots in camera. push the shadows 300%, NOTHING CAN CLIP TO BLACK !!!!
i'm not saying hdr is crap, or dr is crap, or it's unnecessary. i'm not saying this at all. i'm just saying that you, as an individual photographer with individual needs, need to decide for yourself if you're getting hung up on some technical "limitation" that has been imposed upon you by The Internet, and in this quest for the dynamic holy grail how many photographic/compositional tools are you leaving on the cutting room floor?
