To the NEWBIES out there:
I started with 120 when I was 16 (1966). I 'decided' that medium format was always better than mere 35mm. My Minolta Autocord CDS 'proved' that. Then ... I began to 'notice' that I could not get close shots, or shots in low light without a tripod. But, I was superior to all the inferior photographers (and don't you forget that!).
In 1978 I tried a Canon AE-1 and this experience blew my socks off. I simply could not believe how an industry dedicated to maximizing the performance of the miniature format could achieve such noble attributes. I never looked back.
'35' does not do everything, but it does do more than one would first fathom. Listen: using Tri-X in medium format will NOT produce a better picture (no matter how much you enlarge) than TMX (ISO 100) in 35mm. Why do I compare ISO 400 with ISO 100? Because, with 35mm you have the advantage of almost TWO STOPS when it comes to equating depth of field (i.e., f8 in medium format approximately equates to f4 in 35mm).
To me, 35mm is the very best overall choice for photography. I am not denigrating the 'Ansel Adamses' out there who have their weighty tripods and time to kill capturing enrapturing scenics. They are to be marveled at. But for a single, simple determinant possessing all the admirable traits, 35mm is the way to go. (And to capture an AA style scenic is not unheard of, either). And SLRs with their inherently more precise framing and shear adaptability, and with the give away prices for those yesteryear cameras, they are the way to go, but you had better learn to work: cleanly, precisely, and carefully, if you want to garner all that 35 has to offer. No excuses, no reprieve. (And if you already have an SLR and think that you are clean, get yourself a magnifying glass and look closely at all the crevices in your camera back and you will be back, in horror, with a damp cloth to clean up your filth!!!)
