Samyang AF 50mm f/1.4 Sony FE

Weighing in at 585 grams and measuring 9.77cm in length, the Samyang AF 50mm f/1.4 FE is a big lens given its focal length, and significantly larger and heavier than both the Sony FE 50mm F1/8 and the Carl Zeiss Sonnar T* FE 55mm F1.8 ZA. As seen in the photos below, it rather dwarves the full-frame Sony A7R II camera, especially with the lens hood attached.

Focusing

The Samyang AF 50mm f/1.4 FE lens has a wide focus ring. There are no hard stops at the ends of the range, making it more difficult to set focus at infinity. Polariser users should be pleased that the 67mm filter thread doesn't rotate on focus.

When it comes to auto-focusing, the Samyang AF 50mm f/1.4 FE is a fairly quick performer, taking about 0.25 seconds to lock onto the subject when mounted on the Sony A7R II that we tested it with.

We didn't experience too much "hunting", either in good or bad light, with the lens accurately focusing almost all of the time. It has quite a noisy focusing mechanism, though, which makes this lens less well-suited to video recording.
Chromatic Aberrations

Chromatic aberrations, typically seen as purple or blue fringes along contrasty edges, were quite prevalent in our test shots, as shown in the examples below.
