Samyang 21mm F/1.4 ED AS UMC CS Sony E

I really wanted to like this one. The built quality and size is good, fast f/1.4 aperture and the focal lenght is interesting since it sits nicely between the 18mm and 23mm from Fuji. But the results I got at wide apertures were really bad. Even with careful magnified focusing the photos were very soft. I had to return it. I've read that this lens suffers a lot of sample variation, so maybe I just got a bad copy. But after this bad experience I'm not willing to try another one, will just go with a safer native brand.

Fantastic build quality and great results! It is my first manual exposure lens and I really enjoying using it on my GH4.
