Found 40.5mm filters for B&W photography

Hi

I'm looking for 40.5mm filters for B&W photography, e.g., yellow, deep yellow, orange, red, yellow green. Any good quality brands will do: Tiffen, Hoya, B+W, Heliopan.

I would like to use it on Pentax 17. Due to the small size of the camera, I don't feel it proper to use 52mm filters with step-up rings.

I'm located in Northern California. Thanks.

If no one offers some up here on the forum the go to guy for filters is Tim at filterfind.net. He has always had a great section, very reasonably priced as well. And he’s located in your neck of the woods too: Berkeley.

I concur; have a look at the filterfind.net website.

His upcoming presence at stores in the Bay area (and email works fine)-
Drop Tim a note about what you are looking for and he'll make sure to bring along the proper box(es).

I have a Hoya UV(0) new in original packaging. And a B+W 040 (Orange) unused in is original plastic case but without the outer paper box. Send me a note if interested and we can work out pricing.
