I wanted to get a prime portrait lens but simply could not afford the Nikon lenses for my D7000. When I saw the Rokinon 85 mmf/1.4 with the AE chip on sale, I had a hard time saying no to this lens after reading the excellent reviews online.First, the construction is solid and offers metal...

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.

Have Nikon D80 and I could not set shutter speed in manual mode with this lens. Great lense but a constant shutter speed severely limits my ability to take varied pictures.

3-stars, maybe 2-stars for this one. Based on the Samyang/Rokinon wide variance in lens quality, I assume I did not get one of the good ones. I purchased this lens for one thing, astrophotography. This makes for a severe test for a lens.

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.
