I'm usually not in discussions when it comes to brands and specs comparison. Reason? Specs are dead. Subjects are live and different people got different tastes. Photography is an art. For the merit of comparing hardware and specs and functionalities, it's down to a matter of hardware lust and geek-o-meter ratings.
Why am I posting? Because I think what EOW did was great. To strip the EXIF info out and getting the above group of people to rethink what high ISO means, what brand means, what different resolution, sensors, processors, blah blah blah means.
In the hands of an inept, even a 1ds3 would be only be as useful as producing a A0 poster size piece of ****. For the master of light, an iphone could put a worthy picture on as a postcard picture. Granted, you can't blow up a 2mp picture from an iphone. But hey, why would anyone want a large format bland boring picture for a 21mp FF sensor?
Every camera has its merit, its use. Its purpose. Its weakness. Its shortcoming. Use them as it is. For what they are worth.
