Is this a new lens? It says 'new item' in the description. Whats the difference between this lens and previous FA 31mm f/1.8 lenses
Asked by: Mike
This is new release from Pentax: it is optically the same as the previous 31mm lens, but with a newly applied HD coating to produce clear, crisp images even under demanding conditions, and a completely round-shaped diaphragm, as well as an SP coating to the front optical element to improve the water/grease-repellent and scratch-resistant performance.

question

I recently purchased a B+W F-Pro Kaesemann circular MRC polarizer filter for the FA 31. I have read where some filters/brands, when screwed down on the FA 31, contact the front lens element...not good. Will it be safe for me to tighten this filter onto my FA 31? Thanks for any advice you can give.
Asked by: Anonymous
You will be safe to use the 58mm B+W XS-Pro Kaesemann Circular MRC Polarizer on the FA 31.
