Been thinking about getting a 305 G-Claron for 8x10 use and it seems a great lens-- nice and small, big image circle, and fairly cheap. But I've read that it's optimized for 1:1 and you have to stop down to f/22 to correct for optical problems when shooting at infinity. So my question is, assuming you shoot it at f/22 or a smaller aperture, is it JUST as sharp as a lens optimized for infinity?
And, what happens if you shoot it at infinity wide open-- how bad is the image compared to a lens optimized for infinity? Would if be a bad lens to get if I'm planning to do almost all of my shooting at infinity and virtually never closer than about 50 feet?
Do people have a recommendation for a better all-around landscape lens for 8x10 in the 300mm range?
