Pros: | Sharpness, full correction | Cons: | A bit slow, fluorite elements seem to be brittle | | Fully corrected from 320nm to 850nm. Be careful : the front cap is dedicated to this lens and cannot be replaced with a 58mm metal one.
Visible : very sharp even at full aperture, with great color rendition. As the front element of mine is cracked, I don't know was is the best resistance to flare that the lens can give, but it seem to be very good (even in front of the sun I don't get crazy results). Pleasant bokeh.
UV (with B+W 403) : the lens shows some focus shift, not heavy, but enough to give a blurred image if you don't correct it. It seems to be as sharp as in the visible range on the test shots I've done.
IR (with Hoya R72) : I used it for two shots only yet, the comments would be the same as for UV
