Picked up this lens after having owned the Sony Distagon previously. I was never happy with it, given its copy variations and the high price.
I must say, I am pleasantly surprised with Samyang's performance so far. Excellent value for the money (I bought it when the Samyang version had a $250 instant rebate).
I'll start by sharing a few images. If you have the lens, please share yours.
Both at f1.4 -
