As I was sitting here debating on taking an old Tamron lens apart, I had an idea about camera/lens design. The idea is to put the aperture diaphragm inside the camera body near the lens mount, instead of the rear of the lens. Has there ever been a camera/lens system designed this way?
pros:
- diaphragm cost goes only once with the camera, not duplicated with every lens
- future-proof lens designs (think of Nikon's "G" lenses on manual-focus bodies)
- continued aperture control even when using lens adapters (ex: EOS->FD, EOS->Nikon, etc)
cons:
- with a diaphragm malfunction, you can no longer swap on a new lens and keep shooting (but I always have a backup body for critical shoots). I've never had this happen anyway.
- other?
Just wondering why they aren't designed this way from the beginning.
