I'm using a 65/6.8 Optar on a century graphic and
although I've only seen polaroids (I made my own pola
back for the 2x3)shot with this lens (I'm on
vacation), there is a definate vignetting around the
edges. Not black, but a darkening on the edges.
Judging from the polaroids it looks to be about a 1/2
stop to a stop difference between the edges and the
center. Anybody using this lens? Did I get a bad one
or is this vignetting common?
