Review: Samyang AF 24mm f/2.8 FE – Small lens, big compromise

In my review of the  Samyang AF 24mm f/2.8 FE I tell you why I think that Samyang has made a few compromises too many in order to keep it small.

Build Quality

The Samyang has a metal mount but I think it is of less durable aluminium. The rest of the lens is made from plastics. The focusing ring is wide enough but doesn’t feel as smooth as that of most Sony FE lenses.

The lens hood is a bit flimsy, rather thin and cheap plastic. It is the right size to protect the front element from most damages but too small to really have any effect on the flare resistance.

In general the Samyang 2.8/24 feels a little cheap. Not as cheap as your typical $99 kit lens but Sony’s more affordable lenses feel nicer.

Samyang lenses have a reputation for failing more often and having higher variance than any competitor’s lenses. According to a trusted source the newer AF lenses are no exception to that. This is one reason why Samyang can offer their lenses at very competitive prices and in part offset be rather generous warranties.

Size,Weight and Handling

The 93g Samyang is a very small lens which makes the small FE 2/28 look big. Only Smayang’s own 2.8/35 is smaller and lighter.

The size is the Samyang’s most important quality. If your focus is on a very light and small kit then there is no real alternative to the  tiny 2.8/24.

Manual Focus

As mentioned before the focusing ring feels ok with a little high resistance and a hard to describe lack of smoothness. I have used worse, but again every Sony lens has a nicer feeling focusing ring. As every other E-mount AF lens the focus is by wire but at least it does not depend on the speed with which you turn the focus ring. The focus throw is short at about 80 degrees. All in all a below average performance.


I used the Samyang 2.8/24 on the older a7II with a rather dated AF module. Usually it is a bit slow but reliable. Not so with the Samyang: I had higher number of misfocused images than I would have expected or had I used my FE 2/28 or FE 4/16-35. I didn’t investigate this further with another camera but it made me enjoy the Samyang even less.

AF is mostly quiet but at times you hear a scraping noise.

Optical performance

The Samyang has a narrower field of view than my other 24mm lenses so it is more like a true 25mm or 26 mm lens.


Out of focus highlights are rendered quite smoothly by the Samyang 2.8/24 but there are distinctive onion rings in some scenarios as well as significant bokeh fringing.

Scenario 1: Close Distance with demanding background

Scenario 2: Close focus, less demanding background

Scenario 3: Medium distance focus, demanding background

Scenario 4: long Distance with demanding Background

So for a wideangle bokeh is good in most scenarios but there are some scenarios where it gives less than ideal results.

Flare resistance

The Samyang’s flare resistance is below average by modern standards. There is very little ghosting but veiling flare is an issue in more demanding scenarios. I would rate it better than almost any legacy 24mm lens but on par with the FE 4/16-35. I took quite a few images where veiling flare resistance was a real issue and I find this to be pretty limiting for landscape photography.

not how veiling flare kills the contrast in the darker parts of the image


At 3.3 stops wide open the Samyang set a new record for any lens I have tested so far. This means that the extreme corners are basically at f/9 when the lens is used wide open. Numbers improve a little as you stop down but the remain close to two stops.

This is easily corrected but it costs some time and increases noise in the corners.

Aperture Vignetting
f/2.8 3.3 EV
f/4 2.5 EV
f/5.6 2.1 EV
f/8 1.9 EV
f/11 1.9 EV


The Samyang 2.8/24 displays pretty complex distortion which can’t be easily corrected by manual adjustments. -4 in LR gave the best results but visible distortion remains. At the time when I write this review (9/2018) the is no profile available in LR but this might change in the future.

before: no correction. after: -4 correction.


Since the Samyang has 9 rouneded aperture blades you get fuzzy 18-pointed stars at most apertures. At f/16 they are somewhat defined by won’t excite anyone.


f/2.8:Good sharpness in the center, okayish midframe and softish corners..

f/4: Very sharp in the center, good in the midframe area und still softish corners.

f/5.6: Very good across most of the frame but the corners remain somewhat soft.

f/8: Corners are okay now.

f/11: Corners improve a little while the center is a tad softer.

Not a very impressive performance. The Samyang 24/2.8 FE is sharp enough for many applications but almost any competing lens is sharper.

Compared to other lenses

The Sony FE 4/16-35 ZA is about five times as big and heavy and about three times as expensive. It is also a little sharper and much more versatile because of the larger zoom range.

Legacy 2.8/24 lenses. I compared the Samyang to the Minolta MD 2.8/24 (plan MD) which is one of the better classic 24mm lenses. I found the sharpness pretty similar (at f/8). The Samyang has better flare resistance, smoother bokeh and is much smaller AF while the Minolta is more affordable and more enjoyable to handle.

Zeiss Loxia 2.4/25The half a stop faster, four times as heavy and much more expensive Loxia is of course the technically better lens. It is a lot sharper. From f/2.4 it is sharper across the frame than the Samyang ever gets. In regards to CA, contrast, flare resistance and sunstars the Loxia is also superior. So if you take your landscape photography serious go for the Loxia.

Zeiss Batis 2/25: A tiny little bit little weaker than the Loxia but bulkier and with AF it also runs circles around the Samyang.

Sony FE 2/28: The not much more expensive Sony weights 200g which is twice as much but very little overall. It outperforms the Samyang in any aspect but distortion and is a stop faster. Unlike with the Samyang I found the AF to be very reliable. So unless you put a lot of emphasis on small size I would always recommend the Sony over the Samyang.



  • Small Size
  • Price
  • Bokeh (most of the time)

  • Build Quality
  • Sharpness

  • Unreliable AF
  • Flare resistance
  • Complex Distortion
  • Very strong Vignetting

Every lens is a compromise between performance, price and size. The Samyang AF 2.8/24 FE puts a very small size and relatively low price over performance. If you don’t push it too hard it delivers good results but in more demanding scenarios I often found it lacking. If a small size is really important to you it might be a good fit for you but to most users I can’t recommend it.

  1. I got the lens when it ‘s released.During the days,I used it a lot.In my opion,the flare resistance is a big problem for me.So,I wanna know if it works better when i choose a bigger lens hood ?

    1. Before I sold mine (and I don’t miss it!) I bought a JJC screw-in hood. It improved flare dramatically, but by no means eliminated it.

  2. I’ve been using this lens from its launch, but the AF performance is quite excellent in my A7m3. I’ve been using this lens for the video(with -x2 digital zoom in 4K) and reportage snap pictures. AF speed and accuracy was fine for both works, except AF-A, which was somewhat laggy.

    l like this lens for its weight, almost identical or even lighter than my lens hoods. The Sharpness is okay-ish, but not quite comparable for other Sony primes and the contrast is somewhat undesirable. Overall it was my best option for my non-pro wide angle needs. I’m quite happy with that, I’d say it is not recommended for serious wide angle works.

  3. Cheap,tiny,light lenses offer medium performance. The only lens i have tried in this category that is an exception is the canon ef 40 2.8 pancake which offers good performance. Bought the samyang 35 2.8 and sent it back after 2 weeks. The best compromise for lightness but twice as expensive is still the sony/zeiss 35 2.8. Better at infinite than the samyang,better corners for landscape and better colors.More robust too. Didn’t like the sony 28 f2 either.Distortion makes it poor for landscapes. This is my experience.Maybe it helps.Happy everything.

      1. I bought the 24mm and 35mm for a trip to Sicily, as I wasn’t sure what I’d need. The 35mm is definitely the better of the two, but suffers from similarly poor flare resistance, average corner performance and poor af-c performance above f7.1 or outside the PDAF area. I’ve owned two copies of the Zeiss before and from memory AF was significantly better, as was corner sharpness. For the money it’s a great lens, but again the 28mm is the better lens for everything except distortion.

  4. Interesting review, thank you!
    Because of the price I was quite interested in its performance, but the compromises made to keep the size down are too much.
    I have had bad experience with the durability of Samyang lenses as well, the first sample of my 14mm had a scratch at one of the inner glass elements at the moment i bought it. The replacement’s corner sharpness degraded quickly over time (<2 years) so I brought it away for repair which costed almost as much as a new lens (no regrets of my insurance yet haha). I wonder if this bad reliability is still an issue in their newer lenses..

  5. Wish you would have ran it against better vintage glass the Leica rokkor 24 comes to mind….. unless it’s really wide I think the old primes follow the 90 10 rule 90 percent of the performance for 10 percent of the price.i would be surprised if the Loxia is much better than the Minolta I reference…

    1. Well that depends a lot on your needs but the Loxia is a lot sharper, has higher contrast, much much better flare resistance and nicer sunstars. For me personally that is way more than 10 percent since I like to include the sun in many compositions.

    2. I have the Leica Rokkor 24 and still use it quite a bit. One thing I will say for it is that it’s so much better on my A7RII than it was on my A7. Specifically shooting into the sun and other bright lights. IMO it was pretty much useless on the A7 because of sensor reflection (especially night city shots).

      I will also add that it still doesn’t compare to the modern Loxias in this regard. However, if you’re pointing it away from bright light, it’s stellar.

  6. Hey Philipp, very nice review. I sign everything you said here because I made the exact same experience.
    I ended up returning my copy and bought the 28 f2 Sony. It’s in my eyes way better and still not that big or expensive.
    The only thing is that I would like something wider than 28 or even 24 with af and a filter tread but I don’t know any cheap lens in this category.
