Description

A little more care is needed with the background and the noise reduction. I find the Samyang fully usable at f/2 when used with a crop sensor. I need two upgrades: One is the never-ending quest for better processing skills. And the other one is the mount!

Version B: I spend the afternoon processing the JPEG with Darktable 2.4.3 for Windows. I am quite happy with the software and the resulting image!
