I have a 305 and a 210 G-Claron. They both do 8x10 pretty easily. The 210 ;does need to be stopped down past f 22 to get the corners covered but it is a passable wide lens for 8x10. The 305 as mentioned above covers 11x14 and handles 8x10 easily. I like both. They are not multi coated but are single coated lenses. Both the 305 and the 210 screw directly into a Copal #1 shutter without any spacing issues.
