This is an uncommon lens, with about 4700 non-AI samples and 3000 K or AI samples. I think this lens is a much better choice than the 16mm f/2.8, since it is actually cheaper and includes 4 built-in filters, neutral, yellow, orange, and red, which is perfect for black and white film photography. The f/2.8 takes bayonet mount rear filters and I've never seen one come with a full set of filters.
