I disagree with Francesco.
The only reason I use a 4x5 is for the movements. Most of the time I shoot rollfilm in it anyway. I have no desire to move in the direction of even larger formats. I love shooting with old, manual everything, 35mm SLRs. That' not to say that I don't enjoy viewing the astounding images produced by Francesco and those who are dedicated to shooting the big stuff, it just shows that people can follow their own interests in completely different directions and still fall under the great common umbrella that is analog photography.
