Hi all,

I know the lens has to be set to infinity and hood/filter removed before closing the camera, but can anyone confirm or refute whether the camera can be closed with one of the special B+W filters that lack a front thread? These are only 3mm thick which I assume includes the lens thread so they shouldn't take up much room. I read elsewhere in these forums where someone ground (?) the ring of a Hoya filter until it fitted but I'd prefer not to take power tools near optical glass!

Thanks,
Scott

p.s. in case you're wondering why I ask, it's because if I ever bought one of these cameras I would almost exclusively shoot B&W which for me means an orange or green filter for outdoor use. Taking it off and finding somewhere to put it is every time the camera is closed is something I think would drive me nuts in short order... I know the filter can fit into the hood which clips on and off but then I have to find somewhere to put that (and a couple of lens caps to keep dust, fingerprints and crap off the filter)

No you can't. The best option is the filter (40,5mm size) in the hood. This combination you can put in a small box. It's very easily to put the hood on and off.
With the actual panchromatic films the use of a maybe Yellow/Orange filter is neglectible. For the C.V. Bessa III 667 a N.D. 0,6 can be usefull (1/500s fastest shutter time) and if you're doing IR , an IR filter too.

It's a pain. I shoot B&W, too -- with a yellow or orange filter outside. I've become pretty adept at screwing them on and off, then placing them in their original cases, which easily fit into my pocket. I could've gone the hood/filter route, but didn't have the patience to order the set-up.

Thanks for the replies! I'm glad I was able to get a definitive answer - this has been bugging me for a while.

Maybe I'll take a closer look at the fixed-lens wide version after all - I need some sort of excuse to justify the extra $, even if it is just to myself!

Regards,
Scott

Justify away...the image quality of both seems striking.

I have the screw in filters. Works fine and a good investment.

The only company that makes the requisite 40.5mm filters in thin mounts, with all the extras, that I found was Rodenstock. However, I cannot locate a Rodenstock dealer. I did locate a Heliopan on Amazon.com in a UV, so that is what I use so far.

I keep the combined filter+hood in a plastic bag inside its cloth bag that came with the hood.
