Which is correct? Looks like a great lens. ===================================================================================================== I have this lens on a shelf at the office, so I'll investigate on Monday. When I last looked under room lighting, it read f/5. I'm guessing that possibly there is a faint f/3.5 engraving there that only showed up under the studio conditions. Maybe the same size ring was used for various lenses, and they blacked out whichever f number didn't apply. I was only able to make two exposures with this lens. Years ago I borrowed an 8x10 camera and shot two sheets of RC paper just to get an idea of its rendering (I couldn't afford to buy a box of 8x10 film). Your testing of that old lens got me motivated to shoot some 4x5 with some of my odd-ball lenses. This weekend I'm going to take some shots with a 12.5 cm. f/2 Xenon on my Speed Graphic. I always wondered what this came from, and Thursday found out via google: <http://www.novacon.com.br/odditycameras/GXN.htm>. The lens alone is a real heavyweight; that camera must have been a handful.
