The first Rokinon lens to feature autofocus, the AF 50mm f/1.4 FE Lens is a fast standard prime designed for full-frame Sony E-mount mirrorless digital cameras. The bright f/1.4 maximum aperture is well suited to controlling depth of field for selective focus imagery, and also suits working in low-light conditions. The optical design incorporates three aspherical elements to minimize spherical aberrations for cleaner, clearer image quality and an Ultra Multi-Coating has also been applied to limit flare and ghosting when working in strong lighting conditions. The lens' autofocus motor works in conjunction with Sony cameras' AF systems for quick and precise focusing performance, and manual focus override is also available for more refined control. A versatile normal-length lens, this lens mixes a fast, bright design with autofocus to present an ideal all-around optic.

Rokinon 50mm f/1.4 AF Overview
A standard prime designed for full-frame Sony E-mount mirrorless digital cameras, this lens can also be used on APS-C models where it will provide a 75mm equivalent focal length.
Bright, fast f/1.4 maximum aperture excels in low-light conditions and also affords increased control over depth of field for working with selective focus techniques.
Three aspherical elements are incorporated in the optical design to control spherical aberrations for increased clarity and resolution from edge to edge.
An Ultra Multi-Coating has been applied to individual elements in order to reduce flare and ghosting for increased contrast and a neutral color balance.
The integrated autofocus motor works in conjunction with Sony cameras' focusing systems for quick, accurate, and precise AF control. Manual focus override is also available for refining your focus position.
Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.

Rokinon 50mm f/1.4 AF Reviews
Beautiful look
By Thomas
Rated 5 out of 5
Date: 2021-11-24
This older version of the lens is definitely showing it's age in the electronics area. But I gave 5 stars because it was on sale, and for the $ it's a beautiful lens that is very fast. The autofocus is probably the main issue. Compared to more modern designs, it's very noisy, and not super fast. So sports would be out. I do mostly live concert shooting, and some interview work, and even with live mics, it doesn't seem loud enough to cause me audio issues. I use all external mics, so if you use the camera mic it would probably cause some issues. The look, clarity and sharpness are all amazing. (For video at least - I cant comment on how pixel peeping photographers would find it.)
Great lens with firmware v33
By Eric
Rated 5 out of 5
Date: 2020-10-03
A good lens made better with firmware v33. Increases speed of AF significantly on A7III. Older AF motors are not silent but are not noisy for stills. Good colors, sharpness, and focus fall off.

question
Has anyone used this for video? I shoot in manual but have used the native sony lenses in the past with AF and Face Detection, wondering how this compares.
This lens will work well for video. It will work with the AF and face detection on the Sony.

question
Can someone with this lens tell me if the recent firmware update that was supposed to help the low light AF also helps the loud AF noise at all? Is that loud AF on all copies or just some? Thanks!
Manufacturers do not indicate to B&H which firmware version is in their product and we unfortunately do not have the ability to check. Please consider that new firmware could be introduced at anytime and it could change even during the time it takes to ship from us to you. We recommend when you receive your lens, check with the Rokinion website to see if you are running the latest version. If not, you can at that time do an update.

question
whats the difference between the Rokina 50mm f 1.4 and samyang 50mm f 1.4?
Samyang manufacturers Rokinon lenses and normally their lenses that match in focal length and f/stop are the same quality. However, the Rokinon AF 50mm f/1.4 FE Lens for Sony E B&H # RO5014AFSE is auto focus and auto aperture while the Samyang 50mm f/1.4 AS UMC Lens for Sony E B&H # SA50F14LSE is all manual. That is the reason for the price differential.

question
Does it come with a Lens hood?
Yes, it does.
Date published: 2018-08-27
question
Does it have face detection/eye AF capabilities?
This lens is a Sony E mount and will fit all Sony E mount cameras. As for the face detection and eye autofocus? If your camera has those functions the lens supports them. I use the Sony A7RII and face detection and eye auto focus work perfectly. I do not know if the A6000 supports Eye Autofocus. I believe it supports face detection.

question
Does the lens that B7H has in stock have the latest firmware update as of 1-25-18 to resolve af in low light issue?
From what I understand, it does not have a firmware update, but as Rokinon herself can help in this quest, I only have more difficulties regarding the agility of the focus.
Date published: 2018-08-26
question
How fast is the AF in low light for moving subjects?
Its fast, maybe not as fast as high end lenses but you pay double to get fractions of a second. Definitely have no issues with the speed for our use. A6300, work camera used to capture conferences, many low light situations but the action isn't as fast either.
Date published: 2018-08-26
question
Will this lens be compatible with Sony A6000, title says E-Mount full frame, just curious to know what will happen if I attempt to use it on a sony a6000?
Google Crop Factor to learn about that.
