Minolta AF 500mm Reflex Lens

Finally got a hold of a Minolta 500mm Reflex Lens, which is a catadioptric photographic lens. This lens, and the repackaged but optically identical Sony Version (SAL–500F8), are the only production mirror lenses designed to have its focus controlled by the camera’s autofocus motor in conjunction with TTL autofocus sensing. In terms of the Minolta AF and subsequent Sony α DSLR systems, these lenses are an anomaly, being the only lenses guaranteed to auto focus at f/8.

This lens will, by default, set the focusing to spot and cannot be changed. This restriction is because of the lens design using mirrors. Since using spot focusing, one must make sure to place the spot focusing square on the subject so it focuses properly. Doing this, focusing is very good, however the depth of field is super slim up close.

This set contains the first test photos I have taken over the last two days. Impressive! BTW, you can compare the Water tower and foothill photos against the less zoomed photos I posted earlier today.
