Owner reviews: Samyang 85 mm f/ 1.4 Aspherical IF

Period of use: 1 year


Smooth bokeh, smooth focus ring.

Very fast lens (f/1.4).

Very affordable for portraiture (for example).


Missing focus chip, aperture is handled manually.

All made of plastic, feels cheap in hand.

A bit soft wide open.


A nice cheap 85mm fast prime lense.

I use it mainly for portraits, but I tried to use it in sports and landscape photography.

Wide open, the lens has a very nice and smooth bokeh, but lacks a bit of contrast and sharpness in center, closing it two stops (f/2.8) helps to improve center sharpness.

As the DOF is very thin at f/1.4 I recommend to use lifeview or having installed a high precission focusing screen in the camera, or you will missfocus a lot of photos.

If you cannot get a prime with autofocus this is a nice option.
