It takes a while to adjust to manual only,,, but well worth it.. tR

very good lens for astrophotography and landscapes/ nightscapes. Sharp and little distortion.

The stream of interesting and sometimes unusual manual focus optics continues with the arrival of the Samyang 20mm f/1.8 ED AS UMC lens. The lens is available in a wide variety of mounts, so let's see how it performs with the Canon EOS 6D full frame DSLR used for this review.
