hi
new around here, thought i'd ask for advice.

i'm looking at getting into LF mostly for shooting buildings, inside and out. before i make a shopping list i need to research a little, on pretty much every aspect of your format/approach, and for now i'd like to concentrate on optics. i'll be looking at wides, probably a 65 or a 75, and later(?) a 120/135, but i need to be able to compare the various models in terms of max aperture, coverage, physical size/weight, and - ehhh... price.

i've done some searches on the matter, and though i usually get plenty of sites, few of them have much, if any, info on lenses this wide.

if anyone could direct me to a good source of info, i'd be very thankful. if not online, then a book recommendation perhaps..??

thanks in advance.
