Introduction

The Samyang 35mm f/1.4 ED AS UMC is a moderate wide-angle prime lens for full-frame and APS-C DSLRs. The Samyang 35mm f/1.4 is a much more affordable alternative to the Nikon and Canon equivalents thanks largely to being manual-focus only. Read our in-depth Samyang 35mm f/1.4 ED AS UMC review complete with full-size sample images.

Announced last year, the Samyang 35mm f/1.4 ED AS UMC is a very fast moderate-wideangle lens for Canon, Nikon, Four-thirds, Pentax and Sony full-frame and APS-C DSLRs and Samsung NX compact system cameras. The Samyang 35mm f/1.4 is a manual focus lens constructed of 12 lenses arranged in 10 groups, with multi-layered and anti-reflexive UMC coatings to help prevent ghosting and flare. The Samyang 35mm f/1.4 ED AS UMC is available now priced at 379 EUR.

For such a fast wideangle prime, the Samyang 35mm f/1.4 ED AS UMC is predictably big and bulky, measuring 11cms in length and wighing in at 660g. While you can use it on a smaller APS-C body or even Samsung NX body, it won't balance very well - as demonstrated by the images above, it's a much better match for a professional-grade, full-frame camera like the 5D Mark III.

Build quality is very good, despite Samyang being a relative newcomer to the lens market. The Samyang 35mm f/1.4 ED AS UMC feels very solid in your hand, even if the outer barrel and the filter thread appear to be made from plastic.

The focusing ring is generously wide and has a ridged, rubberised grip band. As this is a manual focus lens only, there's a distance scale that runs from the closest distance of 30cm to infinity, with a handy depth of field scale for f/2.8, f/5.6, f/11, f/16 and f/22. There's also a small white dot that appears to be an infrared focus index.

At the base of the lens is an aperture ring, adjustable in 1 stop (1 EV) intervals, which has a definite clicking action. An uncoupled (de-clicked) manual aperture version of the lens is available on special order if your main interest is shooting movies rather than stills.

The lens is supplied with a detachable petal shaped lens hood, lens caps and soft lens bag. The filter size is 77mm. Focusing is performed internally so the Samyang 35mm doesn't change length and the filter thread doesn't rotate, good news for filter users.

Note that the Canon version that we tested doens't have any electronic contacts for transferring exposure information to the camera body - there is a Nikon AE version available that can do this.

Chromatic Aberrations

Chromatic aberrations, typically seen as purple or blue fringes along contrasty edges, are impressively well controlled with this lens - the examples below show the worst-case scenario.

Light Fall-off

With the lens wide open at f/1.4, you can see some noticeable light fall-off in the corners. Stopping down helps, although to completely get rid of this phenomenon, you will need to use an f-stop of f/4 or smaller.

Macro

The Samyang 35mm f/1.4 ED AS UMC is not a macro lens. The close-focus point is at 30cm from the film/sensor plane. The following example illustrates how close you can get to the subject, in this case a CompactFlash card.

Bokeh Examples

Bokeh is a word used for the out-of-focus areas of a photograph, and is usually described in qualitative terms, such as smooth / creamy / harsh etc. One of the reason to buy a fast lens is to be able to isolate the subject from the background, which is normally very hard to do with an ultrawide lens. Samyang was apparently very much aware of this requirement, as they employed an iris diaphragm with 8 rounded blades for a pleasing rendering of the out-of-focus highlights. Based on what we have seen, we can say that they largely succeeded. Below you'll find some examples, but you are also encouraged to check out our sample images.
