Interesting just how international this forum is - of four replies to the "location" thread, I'm the first from the US (Vermont, as it now says in my profile )... I wonder what the percentages are as a whole? Location also matters in terms of how easy it is to test and compare equipment. While someone who lives in New York City (or, probably, London, Tokyo, Shanghai,Los Angeles, etc...) can walk or take the subway to dealers for ANY camera or back brand, there is not a single medium format dealer in Vermont (apart from one used-equipment store that sometimes gets a few older bodies and lenses). Boston is a four-hour drive away, and has two dealers that carry some MF gear... I'm probably going down there this weekend.
