Small size, low profile. Works pretty good in low light siturations, surprisingly so.


Cause some overblown shots in bright ligh if a lens hood is not used. The small diameter ( 33mm ) makes finding filters and such tricky.


A very good lens. A lens hood can be kitbashed, if you are unable to obtain one. If you prefer protective filters on your lens that might be a bit tricky. Your best bet in that case is to look up Kodak Series Filters to the appropriate size.
