scottburgess replied to the thread Head Turning Canon Tilt-Shift Optical Designs.
I'm thinking the 24mm TS-R may not be out until 2027. I don't expect a 180mm-ish macro until late 2026 at the earliest. Canon's...

Do you think we should complain to Canon that our well-used 200-800s haven't broken in two?
AlanF replied to the thread Lens Design?.

AlanF replied to the thread Lens Design?.
One important point about signal to noise and extenders that is not widely known is that if you increase the iso to compensate for the...
