This long-focus, wide aperture lens is perfect for portraits, and pretty good, although long, for a walking about lens. The only drawback is the weight, but if you carry a Nikon F3 with the motor drive, (as I do...) you should be used to weight!

I had done enough research to satisfy my curiosity about the product and was not disappointed in it at all. It does what it says it does and that's all there is to it. The lack of autofocus might be a problem for some but it is clearly labeled and marketed as manual focus so this shouldn't be a...

    Blurry Focus

I’ve read reviews and watched many youtube videos before purchasing this lens and it lives upto the hype. It is full frame but I’m using it on an apsc sensor. Look at my attached images and be the judge!

I wanted a 135mm equivalent lens for those times I can't zoom with my feet. The Fujifilm lens for too expensive for my limited use (I tend to shoot wide, not telephoto). I shoot landscapes, not portraits. Therefore manual focusing is not a problem.

I'm very satisfied with the performance of this lens. It's sharp wide open and contrast is pretty nice. <br /><br />As the DOF is very thin for a 85/1.4 lens, accurate focus is critical. I also have Zeiss Plannar T* 85/1.4 and Zeiss Sonnar T* 85/2.8 - all three lenses are wonderful.

    Manual focus only

I really love the built quality and the image quality as well. Professional result, but the only downfall is that it a manual focus only. So far serve me well. Thank Rokinon.

This is one of my favorite lenses, and it always stays in my bag for portraits. The sharpness and contrast are unreal. The huge focus ring is perfectly dampened with a long throw for precise focus. Also, the lens has some weight to it.

Great lens for the price. The manual focus forces you to take more time to take the picture and think more about composition and posing. It seems to be at it's best wide open to about f2.8. It would be nice to have it chipped so it relays aperture and focal length back to camera.

Great lens for the low price. Approx 100mm on an ASP-C camera Needs manual focusing using live view, best used on a tripod with remote shutter release.

The lens works perfectly with my Nikon D3200. The confirmation chip will trigger the green light in the view-finder when the object is in focus. A very nice shallow depth-of-field effect can be created with ease.
