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...

If your looking for a low light lens for photo or video look no further. I shoot in nightclubs and needed a 1.4 lens so I didn't have to use a LED light to catch all the details. This lens works great! The lens is super sharp and the low light performance is out of this world.

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...

This is a very well built very well designed very sharp lens. Ansel Adams would have wept with pleasure over this lens and I mean that. I use it in the field when I want to separate my subject from the background.

I use this lens on my Nikon D750. It's hard to tell whether you are 100% in focus. But when you are, amazing lens!

First off, this thing is hefty, but in a good way. You are getting 1.4 after all. For comparison, it's a little heaver than my DA 55-300. It's a joy to handle. The focus ring is smooth and nicely damped.

I am very happy so far with this lens. I have a few other Rokinon lenses that I use with my sony and minolta maxxum bodies. They are auto focus. This is a fast 1.4, manual focus lens. I like the idea of focusing myself, it gives me more control.

This is a fantastic lens for the price. Using it with my new full frame Pentax K-1. Nice for skin tones. Even focus.
