Rated 5 out of 5

Punches well above it's weight class

Picked this up with the very basic requirement of "fast" and "cheap enough that if my kid obliterates it I won't be too bummed." The attached photo was the very first I took with it, and it was shot one step outside the Adorama shop in NYC... at F1.8 and blind from the hip. Positive first impression? Check. I snapped a few more shots (all wide open) and then went about my business. When I pulled them up the next day, I was honestly shocked. Sharpness is great, distortion is very minimal, and it's full of character and vibrancy. I expected default kid photos around the house... I did not expect a completely solid walkabout lens. Still have to test the autofocus more thoroughly, but it grabbed people on the street walking at NYC pace no problem. I could lock onto faces and track them through intersections amongst other people no problem. It seems very fast to acquire focus in AF-C... easily grabbing people some 40+ feet away (catty corner busy city intersection) and rifling off shots at 10 frames per second without missing focus. It weighs nothing and it's built like a toy... but man, this thing is out for blood.

Pleasantly surprised!

I don't know if Rokinon has stepped up their game or what, but this was a sharp lens even wide open. If Rokinon keeps this up, I don't see the need for bigger heavier lenses. One reason I went mirrorless was to use lighter lenses. I might have looked away from Rokinon before, but I'm glad I gave them another shot and look forward to the future.

Rokinon 45mm 1.8: great value lens.

Good value. Fast and quiet auto focus. Close focus distance isn't the best. Wish it had a AF/MF switch on the lens. Overall very pleased with the lens.
