I've been given a barrel lens - a No. 6 Ser II Dallmeyer Stigmatic F/6 lens that is marked as 10.7 or 27cm length. Can't seem to find much inf from these archives or google. It covers the 8x10 with some movements (no pics yet, just GG gazing). Any info would be appreciated. How does this design compare in practical usage from say, a Kodak anastigmat where the astigmatism is dealt with. Thank you for your insights.
