Surplus Shed lenses - image circle sizes/film coverage?
Just curious if anyone who has tried them has rough ideas about the image circle sizes or approximate film coverage of Surplus Shed's various lens types. I'm particularly interested in their meniscus, plano-convex, achromatic and bi-convex lenses in the 50-90mm range.
I asked Surplus Shed directly, they said they don't have any data on image circle sizes or approximate film coverage for any of their lenses.
Just a little DIY exploration :) Thanks!
