This was shot on a Rodenstock Xenar 135/4.7, single coated, from 1957. I'm sure it's not "the best" lens, but it is a Tessar-type, I think it is probably pretty standard for the Graphic, it's got its own look and it must be cheap. The shot was using a 23 roll-film back, so I can't comment on vignetting or edge quality at 4x5 as I haven't got results from that size yet.
