    The image circle of the 120mm f 5.6 Apo Symmar L is actually listed by Schneider as being 189mm (at f22) which is much greater than the 166mm suggested by Trevor. In addition, you will probably find that the image circle is closer to perhaps 194 or 195mm (possibly more); Schneider tends to be conservative in its estimates. As long as you can live within the image circle this will be a fine addition, superb performing, small, light, and compact package.

    Thanks for the correction on the 120's image circle Rich. I was quoting from Robert White's website.

    Yes, I had spotted that typo on the Robert White web site

    Thanks for your opinions of the ASL lens range and of the usefulness of the 120mm lenght of lens

    I believe that there are no modern duff lenses - just great or even better

    The image circle is a little tight - even at 189mm - but I have found I use less shift/rise/fall than I expected - a little bit seems to go a long way

    Thanks for the advice

    Martin
