    Cons: Only cons I can think of: not weather sealed build in hood prevents mounting filter holders for lee or cokin.....although this is easily corrected by adding some extender rings

    Pros: Oustanding build quality, relatively small size, but feels substantial in hand. Build in metal hood. Fast AF. Aesthetics - premium design. Optics - great bokeh for wide angle. Very sharp and plenty of microcontrast. Small chromatic aberations for an old lens. F1.8 aperture. 58mm filter thread.

    Summary: Truly premium lens - etalon of Pentax limited lenses. Bokeh rendering + sharpness at low apertures gives photos special interesting look, that is unique.

    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.
