Rokinon 135mm F/2 lens review

The Rokinon 135mm F/2 was Built for Astrophotography

|Camera Lenses|3 Comments

In this post, I'll explain why I think the Rokinon 135mm F/2 is the perfect addition to an arsenal of astrophotography lenses.  Deep sky astrophotography is often associated with a camera and telescope, but the truth is there are a lot of great camera lenses for astrophotography out there.

The iPolar Electronic Polarscope The iPolar electronic polarscope uses a small camera to u…
