Hi Moose!
Viv 2x eh? AG seems to love it as well. Having just gone slightly overboard
with the 18 and 35 shift (hey, I sold two N*kkor shift lenses to finance
that exchange...) I will have to wait a bit before another purchase. What's
something like that worth?
I'm really enjoying the F280, by the way.
As well as your lengthy and informative OM posts!
Much appreciated,
Rob
