He certainly couldn't afford the best gear, though his cameras improved.
    Drew our off topic was about if AA's negatives are blurred or not. What I say ís that we cannot judge that from his 2x prints because even today regular enlarging glass is not good at 2x.

    IMHO he was using a Cooke Triple with wisdom. The Moonrise was taken at f/32, an aperture that was not to limit the performance of his lens while ensuring focus depth in the negative plane, and then he nailed the exposure having lost the photometer, so a perfect job.

    This is in the new market, but in the "not new" market we have the R 210 that covers well 810 at 2x, or the R 240, that would not be beaten by regular enlarging lenses at 2x. Another thing is that probably we would need a magnifier to see the difference.

    Sure a R is a pitfall for 35mm, for MF and even for 4x5, if not for duplicating slides, because greater than 2x is common. But IMHO for 8x10 an R can make sense for extraordinary 20x16 prints (2x) that would show a surprising amount of detail when inspected with a magnifier, with quality closer to contact print quality.
