Hi,
can anybody explain the differences between these (and other?) 500-series
lenses.
I can buy a 250mm sonnar C, but the seller doesn't seem much acquainted with
Hassy equipment.
I'd like to know in particular:
- does it have DOF preview?
- does it have "X" flash sync?
- does it have EV locking?
Anything else I should pay attention to?
(I want to use it with a 503CW)
TIA

Steven
