Cons: Its front heavy and large compared to its peers the 43 and 77
Pros: Build quality is superb. Image quality is draw dropping, its difficult to describe until you use it to take an image yourself, images just seem more alive, could be micro contrast or the vividness of light transmission but it is doing something special.
Summary: Not a lens to be judged purely on benchmarks, it needs to be judged on the image you receive. Price wise, can be expensive but don't forget you are buying a lens aristocrat :-) I got mine 2nd hand and it equated to €675 which to me is a bargain for what it delivers.

Cons: Relatively large, heavy, and expensive.
Pros: Outstanding image and build quality.
Summary: My standard normal lens on the K20D. My standard wide-angle on the LX. Near to perfect image quality. However, when size and weight matter, I sometimes replace it with the A28/2.
