Right on. Those are some nice leads. Thanks!

WOW. Thank you for personally weighing in Mr. Mullen. I greatly admire your work and thank you for responding to my humble c-mount lens question. It looks like despite my fear of ebay, I may have to go that route and hope I get some good c-mount glass. I found these, almost a complete set of Som Berthiot Cinor lenses that look really good. http://www.ebay.com/itm/Som-Berthiot-Cinor-20mm-f1-5-C-Mount-French-Cine-Lens-16mm-Camera-Bolex-Filmo-/131012350617 and http://www.ebay.com/itm/Som-Berthiot-Cinor-25mm-f1-9-C-Mount-French-Cine-Lens-16mm-Camera-Bolex-Filmo-/131012374752 and http://www.ebay.com/itm/Som-Berthiot-Cinor-75mm-f3-5-C-Mount-French-Cine-Lens-16mm-Camera-Bolex-Filmo-/131012332232 I wouldn't have a nice wide, but I'd almost have a nifty prime lens set if I snag these. Does anyone have any experience with the Cinor lenses from Som Berthiot? If so, will these go for a lot and simply break my heart drooling over them or could I win each for about $100? I can't seem to find these lenses in previous auctions so I don't have a reference point. Does Som Berthiot make a 10mm Cinor off hand? Then the kit would be complete! Thanks, Mr. Mullen and everybody else too. David

Wow. Did not know that. About the x-rays or the lenses doing it on their own. Thanks!

If this came off an x-ray machine I might steer clear. I have heard of some lenses being radioactive. This possibly could be how they get radioactive. Caution is advised.

Thanks everyone for weighing in so quickly. I guess my worry was what David Cunningham mentioned. With the 35mm lens you are using the center of the lens and zooming in and not using the full optical properties of the curvature of the glass so when doing that will the image go soft? I have a nice Switar but it is an odd 16mm focal length (not real wide but not normal for sure) and I'd like to use some Nikon glass with a c-mount adapter. So that brings me to the worry about which c-mount adapter to buy because Heikki Repo's comment has me worried I will get a bum adapter and have everything out of focus entirely. The parrellex viewfinder is fine for my intended framing but non-sharp images are not. SO I should hit "flea bay" and try and stock up on some c-mount glass? Ugh... I hate buying stuff from that site. And my local craigslist doesn't have the population to draw real filmmaking equipment. Me and simply one 16mm Switar is so depressing right now... David

Hello, I recently acquired a Bolex 16mm camera I would like to use with a c-mount adapter that will let me use 35mm still lenses on the camera. It is the single port Bolex. So it will not have the reflex prism in the light path. My question is, all things being equal, will I see a resolution loss when using 35mm still lenses as they are designed differently. Will a nice c-mount Switar prime give me sharper images over a Nikon 35mm still lens? Thanks. David
