Re: 90 summicron and viso 2.

[Hal Robinson <sparky16@ix.netcom.com>]

Thanks for helping me with my viso and various lenses a few weeks ago.  I
have tried different lens and all seem to work fine.  I had excellent
results with my dr summicron set at 18 inches.  My only question is how many
stops do you lose when a lens is put on the viso in this way for close
focusing.  I have found this to be the case with my 90/2 and 502 after this
role I just got back.  I am guessing it is around 1-2 stops but not sure.  I
didn't even think about losing stops until after i shot the role, and i use
a hand held meter with my m4.  Thanks again, Hal
