Quote:Just curious how does that work? (since you've likely seen it when testing old Sigma & Tamron long lenses). What does the aperture indicator read and what happens if you try to shoot at "f/5.6"?
Yes, I wonder about this actually too, how does it work? There are a number of lenses out there, e.g. Tamron 18-270 that are 6.3 at the long end.
