We finally didn’t have rain, snow or arctic winds to rival McMurdo Sound, so I finally took the 500mm Opteka mirror lens (with 2x TC!) outside for a few shots.
It’s about what I expected. Field of view and depth of field are pretty small, but it’s no worse than I remember my old Soligor being.
I’m looking forward to warmer weather and sunnier skies so I can take it up to the lake.
