Verdict

It may be a bit embarrassing for the original manufacturers, but the Samyang 24mm f/1.4 ED AS UMC manages to produce a quality similar to its roughly double-priced counterparts. Admittedly, the 24mm f/1.4 suffers from slightly lower contrast at large apertures, but the resolution is already pretty high here, and that's including the difficult outer image regions. The results get more snappy at f/2.8 and beyond the lens is very sharp indeed. Typical for such lenses, the Samyang produces a heavy amount of vignetting at large aperture settings so it's advisable to correct the issue during post-processing or by stopping down to at least f/4. The barrel distortion is a bit stronger than average, albeit not extreme. While we didn't really test the quality of the bokeh formally this time, the field results look pretty good - normally, ultra-wide lenses are somewhat on the rough side here. There is some visible bokeh fringing at large apertures, but this is, again, nothing out of the ordinary. The weakest aspect of the lens is possibly its rather limited protection against backlight, especially sided light. We have seen some higher-than-average glare and ghostings so you should always mount the supplied lens hood in difficult scenes, although this will not always help, of course.

The mechanical quality of the Samyang lens is on a very high level. It may not be a full-metal lens, but the body is made of high-quality materials, and it's a joy to use the damped focus ring. A limiting factor is certainly the lack of AF as well as the uncoupled aperture, which forces photographers into a rather classic style of shooting again. Magnified Live-View (or a split-image viewfinder screen) can help to overcome some of the focusing problems, but it will slow you down for sure. However, again, keep in mind that the lens costs just ~660EUR so similar to its 35mm f/1.4 and 85/1.4 stable mates, it's a fairly obvious choice for budget-oriented users with a desire for low-light photography and/or shallow depth-of-field potential.
