Product Description

Style: Pentax

Product Description

The Rokinon 85mm f/1.4 Manual Focus Lens for Pentax is an ultra-bright lens with a maximum aperture of f/1.4. Although you can only use this lens in manual focus mode, it is fully compatible with the automated features available with digital SLR cameras. It is compact and lightweight, and offers the ideal focal length and bright aperture for use as a portrait lens.

From the Manufacturer

The Rokinon 85mm F1.4 Aspherical Lens is razor sharp and crystal clear for photo and video.  It is widely used as a portrait lens to shoot ultra-bright & vivid portrait pictures.  Rokinon’s 85mm lens stacks up extremely well against the Canon EF 85mm f/1.2 and against the Nikon 85mm f/1.4.  It is also the least expensive lens of its kind in the market!  The lens is manual focus and the aperture needs to be controlled directly from the lens, but at a cost of less than $300, how can you go wrong? 

The Rokinon 85mm lens is made with mostly glass and aluminum components and the build quality is superb.   Its focusing is silky smooth with an internal focusing (IF) mechanism so that the physical size remains constant during focusing.  There are little or no chromatic aberrations and Bokeh is just about perfect.  The lens comes complete with a removable lens hood, lens caps, lens pouch, instruction manual and one year warranty.   The lens is available in the following mounts:  Canon, Nikon, Pentax, Sony & Olympus 4/3.  There is also a slightly more expensive version (Model # 85MAF-N) for Nikon that features a built-in focus confirm chip.

Customer Reviews

The bokeh is beautiful and it creates very sharp images.
T. K. kim
The Manual focusing ring is well damped and smooth as silk, making accurate focusing easy.
Rocco Y.
The manual focus with confirmation is easy to get used to but does take some practice.

Style Name: Pentax
Image quality from wide open
Construction quality
Video use

Image quality doesn't improve a lot stopping down the aperture
Included 72mm lens cap is junk
Hood not positive feeling
Focusing at 85mm f/1.4 is difficult
About 1/3rd stop darker than my other 85mm lenses

Bottom Line:
Buy this lens now if you want a superb manual focus long portrait lens of modern design and don't want to empty your pocket book. It performs like a name brand 85mm f/1.4 at a fraction the price. You must be proficient with manual focus to use this lens at f/1.4 (or be willing to learn).

The lens produces nice usable portraits from wide open. There is a pleasing softness too it, but the eyes appear nice and sharp and the bokeh transitions are smooth. Specular highlights in the bokeh are smooth and fairly uniform with minimal rings or donuts. The modern aspherical lens design takes care of most spherical aberration. I bought this lens solely for f/1.4-f/5.6 usage. If I want to use the f/4+ range I will use my f/4 zoom, so wide open performance of the 85mm was critical too me, otherwise it added nothing over my slower zoom. I would not be afraid to use this lens at f/1.4 for portraits.

Wide open it does show a small amount of purple fringing around very high contrast subjects, but it almost has to be blown out next to a darker object for it to be noticeable. The lens also has your typical green/red chromatic aberrations (CA) visible in the bokeh, which I think is longitudinal CA. This is actually fairly typical of large aperture lenses, even good lenses. It is generally not intrusive. The lens is also a tad darker than my other 85mm lenses, maybe 1/3rd f/stop.

Style Name: Nikon
I had really never heard of this company or their lens until I happened upon a few web threads from various forums, specifically fredmiranda and dpreview.

After seeing some amazing images posted from owners of pretty much every camera brand and seeing great bokeh and sharpness comparison shots, I knew I had to get one.

Just got it today (April 13) and it's awesome, awesome, awesome, especially given the price.
I'm using my lens on a D700.


OPTICS - Outstanding. Seriously. I started shooting this thing wide open at f/1.4 and it's just great. Before this lens, one of my more enjoyable lenses was the outstanding Nikon 105mm f/2.5 AI-S. I think this lens, though, beats it. It's a more comfortable length for me, and the build quality is pretty high - and the bokeh is just amazing.

Did I say amazing? How about just delicious. Creamy, smooth, great transitions from focus to unfocused areas. It's great after some initial testing and already I have a shot of my young daughter that is frame-worthy (straight from the D700 using RAW and "normal" profile).

BUILD QUALITY - Well, you don't get something for nothing, but you can come very close with this lens. It looks like it's a combination of heavy plastic and metal. The focus ring is of adequate size and mine has absolutely no play in it - damping is pretty good. And hurray for Nikon, Rokinon made the lens focus the "right" way, so that AF confirmation in your camera is going to match which way you actually need to turn the lens.

The lens hood is probably the weakest part - it's pretty flimsy, cheap, falls off too easy and is hard to line up to reverse for storage. But hey, this thing is dirt cheap and gives amazing, inspiring results.

Style Name: Nikon Verified Purchase
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.

When I used the Nikon AF version, I found myself having to manually focus to get the plane of focus just where I wanted it and so decided I really didn't need to pay extra (almost a $1k more) for the AF feature. So the only thing that would make sense for paying more was if the Nikon's Image Quality was significantly better... it wasn't. In fact, at f/1.4 (which is where you will be shooting this lens 99% of the time, else why buy an f/1.4 lens) I found the Rokinon/Opteka to be sharper and have more contrast than the Nikon.

There are a lot of reviews to be found on the inter-net for this lens. Some express concern for obtaining a good "copy". I am sure this lens is not as consistent in its build quality as Nikon is, but I got lucky right out of the chute with my first one. It is amazingly sharp, mechanically sound, and the IQ is just what I needed it to be (bokeh is wonderful).

Bought mine through Amazon from Cameta Camera. Great store with quality customer service.

For the price, you really can't go wrong.

Style Name: Canon
First of all, there is no point to compare this manual lens that has really fast F/1.4 aperture with autofocus lens or Canon F/1.8 lens. Depth of field is so narrow at F/1.4 that focusing is almost impossible without Live View and tripod. Another very simple and cheap solution is to glue a focus-confirm chip to the lens to get a reliable focus confirmation (light and beep). It's a shame that Rokinon didn't do that from the start. Taking into account the only use of this lens as a portrait lens, manual focus is not an issue due to steep price of Canon 85/1.2 and lack of 85 F/1.4 Canon lens. Nikon do have such 85 F/1.4 beauty at price 5 times that much. I was waiting for Sigma 85 F/1.4 but there still no reviews and you have to wait 6 months more to be able to buy it at a real, not introductory price.

I based my choice on professional reviews and Flickr sample photos of all comparable lenses. I was convinced when checked the bokeh quality of Rokinon comparing to Canon 85 F/1.8 and read favorable review of Ken Rockwell who generally doesn't even touch third-party lens. Don't have much personal experience with other 85mm lens (besides venerable and considered good Minolta MD Rokkor 85mm F/1.7 lens that is priced slightly above Rokinon. Please note that Rokkor requires some skills(and money) to be permanently converted to EOS).

Other brands of the same glass (afaik): Vivitar, Bower and more!

Focus: it's easy to achieve by using Live View with magnification and tripod or focus-confirm chip. You could stop a lens down to 2.0 to achieve more DOF to ease the task.

Metering: Camera should be in Av to auto-meter. My Rebel XTi do not meter correctly with any manual lens when stopped down to more than 5.6. Not an issue as I need f/1.4 - f/4.0 only.
