... Compare drawn to the fixed focal lengths that have no red ring. here I do not know anything, but there are only 3 lenses I value certify very good in things, that would be the 35mm 2.0 IS USM, the 50mm plastic bomber and the 85er 1.8II 1.8. The lens is at maximum aperture sharp, absolutely fail, quickly and quietly. a true dream! unlike most objective it is already at full aperture sharp, rich in contrast, something is not always available and surprised me very positively, ..... but it has a shortcoming, these are the fringes, chromatic aberration, but also to to dismantle, at least weitgehenst.
