Quote from: xoda on May 03, 2024, 07:51:21 PMI have the Pentax 67 400/4 ED-IF. It's optically fine at 100MP. It's just too heavy, so I never use it.Quote from: MGrayson on May 02, 2024, 06:44:14 AMThis, but it weighs 14 pounds. 800mm f/6.7
Less insane is this. Only 10 pounds. 600mm f/5.6
There's a mirror 1000mm f/8, if you don't care about the bokeh.
Curious if any one has any experience (even second-hand experience) with either of these lenses on a modern digital camera?
