Excerpt: Optically I think this lens is good. However, I really don't like it when it comes to ergonomics. The focus ring will turn when focusing (it is not suppose to but this happens sometimes). The focusing motor is so noisy and vibrates. I feel like I am using a lens from the 90s. For me, the worse is that the AF is not really usable for me when I use it with a7R and LAEA4. The center focus point works fine after af micro adjustment. However, the outer points never works.
Summary: The Good: It's a Zeiss lens with autofocus for Sony. Us Alpha shooters take this for granted, but having autofocus with Zeiss optics is a rare treat. The lens has a very nice look, feel, and weight to it. It feels more like a Carl Zeiss product and less like a Sony. The glass is recessed enough that the front element is not as exposed, leaving you feeling protected from accidental damage.
Summary: I bought the Rokinon 85mm f1.4 for portraits and family pictures. It fit perfectly on my Nikon D5100. I got the one with the chip so the camera was able to communicate with the lens. The camera actually prompted me to set the lens aperture to its smallest f stop (f22). Once I did that, the camera was able to adjust the lens aperture automatically. All I had to do is just dial in the desired f stop on camera settings and the camera did the rest.
Summary: Extremely sharp. Some CA wide open but stopping down fixes that. Heavy. Built like a tank. Nice bokeh. Takes skill to use effectively because the depth of field is so shallow at wider apertures. It takes beautiful portraits and does well when an 85 mm zoom is appropriate. I took it to a market and had fun with it. My only complaint is the focus mechanism is a bit clunky compared to more modern systems. Attached photo taken indoors without flash and no preparation.
Summary: I was all set to pull the trigger on a used Nikon 85 1.8 AF Nikkor, but of course, the one that I had been looking at on KEH just happened to sell before I could snag it myself. I had been researching this Rokinon lens as an alternative, and seeing that Amazon had a deal on the shipping, pulled the trigger. I really liked the idea and challenge of going old school and focusing manually. I got the lens today and did some testing, and it performed as expected.
Summary: I bought this for use as a portrait lens and I have been very pleased. The aperture is controlled through the camera on the Nikon D3100. The lens has a nice feel and operates smoothly. Focusing is a bit of a challenge at low F-stops but that is to be expected. The chip in the lens allows the autofocus sensor to signal when it thinks the subject is in focus.
Summary: From all the brands I shoot and all the lenses I have every shot with, this is by far the best image quality I have ever had. Rent it, borrow it, just look at picture other photographers have taken with this lens and decide for yourself.
Summary: I have the Rokinon version of this lens. It is great! I use it on a Nikon D700 and have compared it with the Nikon AF 85mm f/1.4 (which I had rented for a weekend to test) and I much prefer this lens to the Nikon.
Summary: Tack sharp lense. It takes some getting used to since its a manual focus lense. Having said that the collar to adjust the Focus is really nice. It has just enough friction to make tight focusing easier. Also make sure once you get it on your camera ( mine is a Nikon D610) change the aperture all the way to where the red number is and leave it there. Your camera can then adjust the aperature.
