Re: What is your favorite camera brand and why?
Nicely revived thread, so I'll throw my 2cents in..
While I have shot Nikon for decades now, my favorite is my Mamiya 645DF with the Credo 80 back. It is far and away the best system I've ever used.
Until you've shot medium format you'll never know how much you've been missing. It is like someone going from taking pictures with their phone to a dslr, that is how much of difference it is once you go medium.
Now it is not an every day camera by any stretch of the imagination. The frame rate is low, the usable iso range is small, and it might be considered a tad expensive for some. For my work photos, this is my go to, and I've never been happier.
