Murray@uptowngallery said:There are apparently 3 varieties/vintages of lenses on the folding pocket 3-A's. I used ths following instinct to decide which ones to bid on.
Based on other Autographic's I've seen, the meniscus ones have a small sloping 'lens' front and a hole, no glass visible in front of the shutter.
The Rapid Rectilinear-equipped ones have a more massive lens visible with the distinctive black-painted lens cell.
There is an Anastigmat variety I have not seen yet to visually recognize in an auction listing...I imagine that would be the most refined lens.
150/9 Apo Ronar?Ole said:Among basic Anastigmats, the Tessar-type lenses have the least coverage of only a few percent over the focal length. So you can safely assume that any anastigmat with a focal length of 150mm or more will cover 4x5".
Repro lenses are an obvious, and well known, exception to the rule. Anything older with "APO" in the name has a ihgh likelyhood of being a repro lens. The only exception I know of is the APO-Lanthar, which has more coverage than the basic Tessar. But that's not a repro lens, unlike the APO-Tessar...Dan Fromm said:150/9 Apo Ronar?

wclavey said:I don't actually have a Speed Graphic or I would have done surgery to remove the blades and used the focal plane shutter... my 4x5 is actually a homemade camera cobbled together from various parts, including a crown graphic bellows, front standard and lensboard, with a graphloc back, all mounted on a rigid wooden frame... not ideal but it works...
Murray@uptowngallery said:Steve - While your Tessar is likely older, being from a plate camera, my Xenar 135, as best I recall, has a spec sheet image circle of 161 mm...barely adequate for , what is it 153-154 mm for a 4x5 filmholder openeing diagonal?
