This was an impulse purchase some time ago, and I'm never going to use it. It's really for the 6x9 format, and I use a 100mm WF Ektar on my 4x5 when I want something this wide. The single-coated glass is decent, though there are some minor cleaning marks and a couple of very fine scratches on the front element. The shutter works on all speeds and the progression sounds correct; I have no idea as to their accuracy. You can see some kind of discoloration or mild corrosion on the blades which doesn't seem to affect anything. The retaining ring and very nice brushed aluminum rear cap are included, but no front cap. No dents or dings. The shutter still has the annoying anti-rotation screw, you'll probably want to remove that before mounting this on a lensboard. This fits a Copal 0 hole. FINE PRINT: This is not the original shutter, but came from a 127mm or 135mm f/4.7 lens. I have a jpeg of the correct shutter face that I never got around to transferring. $70 plus shipping, which is what I've got into it.
