Love this lens! I own a video production company and prior to this had the Canon 50mm f/1.8 STM and hated it. Pulling focus with a STM lens is the most terrible thing you can try to do. Pulling focus with this is super smooth and since it is longer as well it is very precise.

As usual, top optical quality from Samyang. I own the 12mm, 35mm, 50mm & 85mm and can say that I like them much better than my Canon 135mm f2 or 16-35 f4. None of the Samyang lenses have autofocus, and to me this is an advantage as it makes me a better photographer.

This manual focus standard lens, offers a fast f/1.4 maximum aperture for a price of around ￡379, which is a little surprising, as Samyang lenses are traditionally pitched in at the budget end of the market.

Decent sharpness; especially when stopped down; Smooth manual focus action; Good build; Low CA

Performance from this lens is on a par with manufacturers own lenses; but nothing special; Pronounced falloff at f/1.4; Seems like poor value for money at current price; Lower contrast than other modern lenses

The photographic version of that lens have recently found its way to our editorial office so now we can present its full test. We would like to thank the distributor of Samyang in Poland, Next77 company, for lending us one specimen of that lens for testing purposes.

very good image quality in the frame centre; sensibly corrected chromatic aberration; slight coma in the corners of the APS-C/DX; low astigmatism

image quality near the maximum relative aperture could have been better; too high distortion; unacceptable performance against bright light; noticeable vignetting

The Samyang 50mm T/1.5 AS UMC (Samyang 50mm f/1.4 AS UMC) didn't really thrill us although it is far from being a bad lens. Its optical qualities simply don't stand out enough to make a difference compared to other 50mm lenses. That being said - the image center is quite sharp at max.
