I just picked up a Samyang 14mm 2.8 that I want to use on my a7r2. got it yesterday afternoon from Amazon and did some test shots. I just seem to have issues either getting focus or the lens is just soft. Have any of you had any dealings with this lens on your sony? If it’s a soft lens, I’d just send it back. If you all have a better recommendation for an economical lens for landscape (something wide), please let me know.
