comment:A nice looking copy of this lens purchased from another Dyxum user. The original front lens cap, hood, and clear filter (rear) were included. The metal screw-on hood is flocked on the inside. "MADE IN JAPAN"

It is sharper than either copy of the Rokinon, but APS-C captures are noticeably soft even at 2 MP. The better x-300mm F5.6 zooms are sharper with more contrast when used on a 2X MC7 teleconverter, and this lens is only about a third stop brighter than those combinations. There is quite a bit of astigmatism and/or coma that makes it impossible to get a achieve consistent focus at all angles.

This version is chipped and Steady Shot works well on the A68. I find Steady Shot with Shutter is needed to be able to use focus magnification hand-held.It works much better on the A7II.
