Hi David, I guess you haven't tried it with Provia or Velvia locked on a solid tripod & head with mirror lockup?
If you got one great, sharp photo, then you will get more, since your technique may be at fault. It's very, very hard to get sharp, hand held tele photos, eben at high shutter speeds. I can't at all. Anyway, thanks again for this info. : ) Best Peter --- David Mann <[EMAIL PROTECTED]> wrote: > I wrote: > > > > My sample of the 400mm isn't quite as sharp as > I'd like, although > > > I may be expecting a bit much. > > and Doug Franklin replied: > > > You might be.
