Grinding for Quality. Samyang 100mm F2.8 Macro Review

I'll start this review by stating a significant fact: I seldom wanted to pick this lens up. Even for an experienced photographer and camera tester like me, the Samyang 100mm f2.8 Macro annoyed me. This version doesn't have AF/AE contacts. So focus confirmation is a lot more complicated. And if you didn't know so already, it's a manual focus lens. You'll work really hard for great photos. But when you get them, you'll be elated. However, I really am not sure that it's worth the grind.
