I've been doing a little research on getting a lens for my Hassy, and everything seems a little fuzzy. For now, I'd like to use it mainly for landscapes but have the verstility to do some occasional portraits and still life (for photography class). I'd like to have the equivilant of about somewhere between 35-50mm on a 35mm SLR. So far I have my eye on the 80mm f2.8, and then possibly getting a teleconverter somewhere down the road. Would this lens be wide enough for general landscape photography? Any suggestion/opinions would be awesome.
