MASSIVELY overrated. What do you think? Everyone's so hung up on this. I spent COUNTLESS hours trying to figure out which lenses had the biggest coverage - even to the point of considering a 150 grandagon for my normal lens on 4x5. I'm an architectural photographer, too - so you'd think it would be important to me. When I do lens rises - they tend to be pretty subtle - rarely more than 10-20mm. And QUITE often I use 5mm or less. I even think it's quite refreshing not to use ANY. More than 10mm on 4x5 just starts to look kind of silly IMHO. Others' opinions?
