Good lens. If you don't have a super precision focusing screen (i.e Eg-S for the 5DII), the MF can be rather difficult. Swapping the screen made a huge improvement in accuracy
I think this is the main problem that many have. Stock screens are generally not good for MF and will not show accurate focus changes when the lens is wider than ~ f/2.8. This is a huge problem with this type of lens. A good screen is an absolute necessity IMO. After that it takes some practice and patience.
I have this lens and I regard it as one of my "art" lenses. In other words, when I want to take my time and get the composition just right this is a “go to” lens. When I want to take shots of my kids, then the 135L comes out with it's fast AF.
This lens is a good buy at the new price, but and insane deal with the price you paid. Very sharp and great bokeh.
