Samyang AF 14mm f2.8 FE

Samyang AF 14mm f2.8 FE


Having already tested, reviewed and supplied sample images for several of Samyang’s lenses including both AF 50mm f1.4 FE and the brand new AF 35mm f2.8 FE lenses, Samyang sent me a copy of their other AF lens recently to test out during my trip to New York. I had in the past also tested their 14mm f2.4 XP lens (which was simply superb – review HERE) so I had previous experience using such wide focal lengths.

The AF 14mm f2.8 FE follows suit with the other AF lenses and is built for use on full frame Sony A7/A9 series camera systems but can also be used on APS-C (cropped sensor) Sony bodies such as the A6500 or A6300 but would give a 21mm relative focal distance.

Design and construction is similar to the 50mm f1.4 with a high quality metal alloy build. However, whereas the 50mm has a detachable lens hood, the 14mm does not. This helps to protect the bulbous glass front element but prevents the ability to use standard filters as there is no filter thread. Maybe a filter manufacturer such as Gobe could someday produce a filter adapter to be used with this lens so that landscape photographers can use their array of filters when out in the field.


Size in hand (I don't have the biggest of hands)
Specs
The lens has 14 elements in 10 groups (3 of which are aspherical) to minimise aberration and unnecessary light dispersion, delivering high resolution from the centre to the corners of the frame. Angle of view is a very wide 113.9° on full frame cameras and 89.8° on APS-C cameras. Aperture ranges from f2.8 at its widest all the way to f22 - pretty standard range. Minimum focus distance is 20cm. Size-wise the lens is fairly compact and weighs in at 505g so during my New York visit while mounted to my A7R it wasn’t at all cumbersome compared to other lenses in my bag.


The Competition
Looking at the other full frame rectilinear lenses which feature a similar focal distance for Sony E-mount cameras it's easy to see that this lens is capable of producing stunning images while offering great value for money. Although not an exact match, the new ultra-wide zoom that Sony has released themselves not so long ago - Sony 12-24mm f4 G lens costs around £1650 compared to this Samyang AF which costs around £600. There's also the older, manual focus Samyang 14mm f2.8 which can be bought for around £375 brand new but isn't as good as this updated AF version. There's also the even wider Voigtlander 10mm f5.6 which is available at around £800 and the Laowa 12mm f2.8 Zero D lens also available for around £1000.

Conclusion
Autofocus on this lens seems to be the fastest out of the three autofocus lenses that I’ve tested for Samyang with very little AF motor noise. Looking at the test images that I've shot below it's easy to see that this lens performs well giving high quality, sharp images throughout the frame. The lens copes well when shooting directly into the sun with little flare (as seen below) which will be great news for landscape photographers. Images are crisp with the optimum aperture around f8 -f11. It offers a great ultra-wide option and is a welcome addition in the range for any shooter with a Sony A7/A9 series FE mount camera or even the cropped sensor A5000/A6000 series cameras.

Thanks for reading. I hope that you enjoyed my short review and test images.I kind of left it quite short to leave the images do the talking.

I'd like to thank Jane at Intro 2020 for sending the lens out to me for testing, Karin and all involved at Samyang Korea for the top quality work going into making these fantastic lenses.

Samyang & Me



My obsession with Samyang lenses first started in early 2013 when I rented a Samyang 8mm f3.5 Fisheye lens after reading good reviews detailing how good the optics were. I was fairly new to photography at that time and wanted to have the lens for a trip to Miami and New York with my wife. I had great fun with this lens while on this holiday. So much so that I immediately bought my own copy when I returned to the UK. I still to this day use this lens for quirky shots. Take a look at one of my favourite images taken with the fisheye (also one of my most viewed images on Flickr) HERE. Also check out some more images shot with the lens below.

Since becoming a Samyang Passionate photographer I have added the AF 50mm f1.4 and 24mm f3.5 tilt shift lenses to my arsenal and both come in very handy. I’m looking forward to using the tilt shift more as this is a fairly new lens for me. I have had extensive use with the AF 50mm f1.4 which has speedy autofocus and produces images with stunning bokeh when shot wide open yet sharp throughout the aperture range. I have in recent months worked with Samyang and tested out some truly amazing lenses. The build and image quality provided by both 14mm f2.4 and the 85mm f1.2 from the XP line of lenses is undoubtedly the best I have shot with. Samyang continue to be at the forefront of optical lens technology with the XEEN range of lenses which I’ve heard nothing but amazing things about. I don’t shoot video but would love the chance to test out some of these lenses to see what I could capture with them. The Samyang brand in the last year has really blown up and produced game-changing lenses for photography and videography professionals both in terms of value for money and quality of imagery. I’m excited to see what this innovative company comes out with next.
