| Latest Review Posted | Carl Zeiss Jena Sonnar MC - Zebra 135mm F3.5
A solid, heavy Warsaw Pact monster of a lens. You're not going to forget that you have this on your camera. Aberrations and sharpness are great, even wide open.
Biggest issue is the aperture mechanism itself, which is prone to problems. Mine has issues returning snapping back to wide-open after being triggered, which is not a problem when shooting. (It will adjust properly if the ring is turned to f3.5, but will only open back to f4-4.8 or so if set smaller and then triggered.)
Far bigger problem, at least with my copy, is that the A/M switch isn't really a switch so much as a DOF preview, and needs to be manually held in place if the camera doesn't automatically stop the lens down to the shooting aperture. (e.g. When used on any Pentax K-mount or pre-Spotmatic camera.) |
