Hunts in AF
MF is touchy
|comment:||I use this almost exclusively on a tripod with manual focusing. Like most macros it is close to perfect optically. Functionally it has a couple of problems. |
1. The manual focus ring is geared too high - very small movements make fairly large changes in focus. In addition, the ring doesn't move smoothly.
2. To switch from AF to MF on a Sony body requires two steps. The camera body first has to be switched to MF and then a ring on the lens has to be pushed out to release a clutch. I believe the lens was designed for Canikon cameras where only the clutch release needs to be changed to switch from AF to MF.
