The Samyang 10mm 3.5 XP is a bit of an odd lens. It is still the widest lens for DSLRs, but it was announced at a time when no one really cared about DSLRs anymore. And it came out after the Voigtländer 10mm 5.6, which surely didn’t help the marketing department. And in the meantime we also got the Laowa 9mm 5.6, which is even wider, has great optics and is small at the same time. So is there still a reason to get the Samyang 10mm 3.5 XP in 2022? Let’s find out in this review.

- Field of view: 130° (diagonally)
- Length: 104 mm (+adapter)
- Weight: 730g (without caps, +adapter)
- Filter Diameter: –
- Number of Aperture Blades: 7 (straight)
- Elements/Groups: 18/11
- Close Focusing Distance: 0.26 m
- Maximum Magnification: 1:13.8
- Mount: Canon-EF

How wide is it?
At the wide end a millimeter makes a big difference, so the difference between this Samyang 10mm 3.5 XP and the Laowa 9mm 5.6 is actually quite staggering. The Samyang is also messing with the camera’s auto white balance and usually gives a very greenish teint overall which I corrected a bit here.
Handling / Build Quality
If you had a look at my Samyang 50mm 1.2 XP review before you will spot many similarities here.
The outer design of the XP series lenses resembles that of the Zeiss Otus, Milvus and Batis lenses and the big rubberized focus ring is the only manual control we have. It turns around ~110° from 0.26 m to infinity and has a nice, high resistance.
The lens features an EF-mount with electronic contacts, I tried the lens with a Sigma MC-11 and a metabones MK IV adapter and unlike the Samyang 50mm 1.2 XP it worked well with both of them.
The lens feels solidly made and I guess most of the internal parts are made from metal, but I did not take the lens apart so I cannot be sure.
The reason I was never personally interested in this Samyang lens can be seen in the picture above. The Laowa 9mm 5.6 is noticeably wider but significantly smaller and lighter. The difference between f/3.5 and f/5.6 doesn’t matter too much to me at these focal lengths and I am not using a DSLR camera anymore, so why would I bother with this significantly bigger lens?
The Samyang 10mm 3.5 XP doesn’t feature a filter thread but third party holders for 150mm filters are available.
Thanks to being this wide and not featuring a normal filter thread our usual method to measure the vignetting figures does not work here. I used a white ceiling instead but I cannot guarantee it was evenly lit in a perfect way.
These values look about right to me though, especially compared to the Laowa 9mm 5.6 which I shot side by side.
At the maximum aperture the Samyang is about 1 EV brighter in the corners, but the gap gets bigger as you stop down. So in this area the Samyang 10mm 3.5 XP has a clear advantage over the Laowa 9mm 5.6 and Voigtänder 10mm 5.6.
Until I used this Samyang 10mm 3.5 XP I thought that a strong color cast is usually associated with compact lens designs, but I have been proven wrong as this lens shows one of the strongest green color cast in the corners I have ever seen.
You can check out my article How to: Correcting Color Cast in Lightroom where I explain different methods to fix this and that I have used for most of the sample pictures in this review.
infinity (42mp Sony A7rII)
Most of the frame looks great from f/3.5 but the corners definitely profit from stopping down a bit. Compared to the Voigtländer 10mm 5.6 E the performance is significantly better still. Now after we saw how big the difference in field of view is compared to the Laowa 9mm 5.6 it warrants the question if a comparison is even useful here. Nevertheless I shot the Laowa 9mm 5.6 from the same position on the same day (you can see it here).
The cornes look better on the Laowa lens but it has a slight midzone dip which the Samyang lens doesn’t.
Stopped down to f/8.0 to f/11 both deliver fine results across frame which is impressive for lenses this wide.
Also keep in mind: with lenses this wide mount (and adapter) tolerances can have a noticeable influence on the across frame performance (especially in the midframe), therefore lens A may perform great on camera B but slightly worse on camera C.
close (0.26m, 1:13.8)
100% crops from center, A7rII
The lenses almost focuses close enough to touch your subject and the sharpness is as good as you would expect from a modern lens with a complex optical design and an internal focus mechanism.
The lens shows moderate distortion but it is a bit of the wavy type and at least in this architecture picture it is easily visible. Unfortunately there has never been a Lightroom profile for this lens, probably because it is rather exotic.
As always evaluating flare is a complex matter since you can get any lens to look bad if you push it hard enough – especially ultra wide angle lenses – and a slight change of scenario can affect results a lot.
Sun outside frame
Sony A7III | Samyang 10mm 3.5 XP | f/3.5
With the sun outside the frame you can catch some internal reflections and also some veiling flare which leads to reduced contrast in most parts of the frame.
Sun inside frame
With strong point light sources inside the frame I unfortunately found some ring flare issues which are unfortunately also a bit persistent as they don’t go away when stopping the lens down.
The performance is worse compared to the Laowa 9mm 5.6 and Voigtlander 10mm 5.6 E here, which isn’t overly surprising looking at this Samyang’s huge front element. But then this huge front element is probably also the reason for the lower vignetting figures. So you can pick the compromise here that fits your shooting style better.
100% crops from extreme corner
Not a surprise after having a look at the sharpness section: coma correction is very good.
Thanks to its wide angle of view this lens also allows for comparably long exposure times when taking pictures of the starry sky without the stars turning into streaks, so the owner has also been using it for this task:
Asymmetrical aperture diaphragms seem to be the norm when it comes to the Samyang XP series lenses, at least for me, as already the 50mm 1.2 XP had this issue.
The result of this wonky aperture diaphragm is that it is very hard to create sunstars at all and should you still manage to do so, they look rather distracing and unnatural thanks to frayed rays with uneven lengths.
If you want to learn more about sunstars have a look at this article.

Usually ultra wide angle lenses show a noticeable amount of lateral CA and this Samyang 10mm 3.5 XP is no exception. Still, the amount is not overly high and this is easily corrected in post by one click.

Colour fringing in the out of focus areas is not really an issue with lenses this wide, but purple fringing might be. Luckily it is well corrected and shouldn’t be something to worry about.
Laowa 9mm 5.6:
As I have shown you the Laowa is noticeably wider and at the same time noticeably smaller and doesn’t suffer from color cast issues nearly as much, so it is my clear choice in this focal length range. Even if you are a mirrorless user the Samyang can still be an interesting choice in case you need a lens this wide which is a bit faster and shows less vignetting though.

Voigtlander 10mm 5.6 E Hyper Wide Heliar:
The Samyang 10mm 3.5 XP is clearly a better performer than this one and so is the Laowa 9mm 5.6. Therefore I see little reason to still consider getting this lens.

Laowa 10-18mm 4.5-5.6 C-Dreamer FE:
If you value flexibility and compact size over image quality and you don’t know yet what focal length is the right one for you this may be worth a look.

Laowa 11mm 4.5 C-Dreamer:
The Samyang 10mm 3.5 XP is the better performer here as well, but this 11mm Laowa lens has a few advantages: it has a 62mm filter thread (widest lens with a normal filter thread), better flare resistance, is ligther and a bit cheaper.

The Samyang 10mm 3.5 XP is a very solid lens and most probably will hold the record for being the world’s widest rectilinear DSLR lens forever. As a mirrorless user I would rather get the Laowa 9mm 5.6 (which I did by the way), but I can still see someone who is less weight and size conscious as I am to prefer this Samyang instead for having the faster maximum aperture and showing noticeably less vignetting. Still, you certainly do need to spend some time in post processing to get rid of that horrible green color cast, at least when using it on a Sony camera.
The Samyang 10mm 3.5 XP is also one of the few lenses that can really benefit from combining it with the Laowa Magic Shift Adapter, turning it into a 14mm f/5.0 shift lens and thereby extending its application range quite a bit. You also need an adapter with electronics (or a Canon camera) to first set the desired aperture though.
This is the second XP series lens that I reviewed and my impression is they are actually pretty decent lenses. The optics are generally very good and the mechanics look solid, too (except for the aperture diaphragms). The problem is: they are DSLR lenses. And because of that they suffered the same fate as the Zeiss Milvus lenses: simply no one bought them because they were released at the end of the DSLR era, when many people already moved on to mirrorless systems.
I would love to see Samyang continuing this line with mirrorless designs so that there is some competition for Cosina/Voigtländer and someone to fill the gap the Zeiss Loxia lenses left, but I guess the dinky AF lenses simply generate more money. What a pity.

10 thoughts on “Review: Samyang 10mm 3.5 XP”
If I didn’t know better, I would think that all of the lenses you review are amazing because you take such excellent photos.
This lens is cool, though I would much rather have a lens that can make nice sun stars because that can be a big deal with ultra wide landscapes. Though, I do like the contrast and colors of the lens. Unfortunately the existence of Laowa and Voigtlander alternatives I think makes this $899 big DSLR lens obsolete. It’s really hard to justify spending more than $400 adapting a lens like that to mirrorless when you don’t even get nice sun stars from it.
I remember that Samyang advertised this lens as “widest (rectilinear) prime” and XP lineup as “suitable for 50MP still and 8K video”. I suspect their optical designs of XP 1.2 primes(35, 50, 85) are used in XEEN MEISTER T1.3 cine lenses. Maybe they were developing XP lenses for cine lens market.
Samyang is pretty small compared to Japanese lens companies. I found their annual sales(FY2020):
Samyang: $48.6 millions
Cosina: $66.2 millions
Sigma: $319.3 millions
Tamron: $360.0 millions
I’m a bit disappointed when they recently released revised version of AF FE lenses instead of new lens. But considering their company size, I guess for business focusing on AF lenses would be right decision. I might consider to buy 85 f1.4 I or 85 f1.4 II after reading some reviews. Those are optically same, but newer one has better AF and ergo.
I didn’t expect Cosina to have a bigger share.
Samyang has about 120 employee and Cosina has 450. I guess more aggressive PR makes the company bigger than what it actually is.
Hwang Chung-hyeon, CEO of Samyang, said “Though we have 85% of market share in US MF lenses sales, but its total share is only 5% in interchangeable lens market. … We wanted to chase after other 95% and released first AF lens in 2016. … ” in a interview. Yes, they will definitely make more dinky AF lenses in future 😉
I’m actually kinda impressed that you can run a company like that with 120 employees… And I rather like some of their dinky AF lenses, heh. Now I’m curious how small some of the other players like Laowa are…
I’d ignored E mount & FF MILCs for years because even tho I don’t mind MF I did want some AF options and it seemed like slim pickings for small ones beyond the 28/2 & 35/2.8. SY’s 75/1.8 was literally the lens that made me do a double take and start looking at what else had come out over the last 2-3 years.
I guess if that hadn’t done it, then the Sigma 90/2.8 would’ve, but there’s still few other AF short teles as small as those two. Aren’t Cosina still doing a lot of OEM work btw? Is that included in the 49mil?
Cosina has several branches, specialized in some area; developing and making optical glass, smoothing and polishing the glass, coating and inspecting the glass, assembling and making glass elements into lenses. I guess Samyang is outsourcing some of those, so they can keep the company small. I’ve heard Cosina-Zeiss OEM could be done because Cosina can control the whole process of making lenses by themselves. Yet, the last Zeiss lens Cosina made was Otus 100 f/1.4(for Canon EF and Nikon F) in 2019.
I also like the design scheme of Samyang, almost all of their lenses are lighter, smaller even cheaper than competitors, but none of them excels competitors either. They just don’t have wow factors like Sigma 35 f/1.2, Tamron 35-150, Sony 135 f/1.8. I hope in some day Samyang could release such lenses. And personally, I hope some good macro lens with AF, which they lack of.
I agree with the awkward timing of this lens, despite it being cool they managed f3.5 at this focal length, on DSLR flange distance.
I think it will continue to be a choice for astrophotography without anything equally fast that’s mirrorless. Not just about speed too, this is a premium-grade lens (although price point similar to Laowa).
I am not sure who has something comparable in the pipeline. Ultra-wide photography is more popular than ever- but popular enough for speed to become a priority <12mm?
There will be something like that next year but I am not at liberty to tell you more about it yet.
Laowa might redesign their 12/2.8 for mirrorless at some point (they did just redesign their 2x APO macro even tho it only shaved like 1.4″ & next to no weight)… I’m actually kinda surprised SY hasn’t made more UWAs lately, besides the 18/2.8, that seemed to be a successful niche for them in the past and it’s not like there’s that many fast options <15mm beyond the 14GM & Laowa's stuff.
I cannot stretch out enough how useful the bright (for an UWA) aperture of F3.5 combined with basically no coma is for astro purposes. F3.5 doesn’t sound great at first but due to the wide field of view there can still be gathered a lot of light which makes focussing quite easy. The low to moderate levels of distortion are also no problem for astrophotography. The lens profile of the Voigtländer 10mm F5.6 HWH may be used to correct the distortion a bit if I remember correctly. But the automatic correction of light fall off has to be lowered then as that profile tries to compensate the much higher fall off of the CV — otherwise you’ll get too bright corners which looks really odd.
The aperture diaphragm design is not the best out there, that’s true. But for beautiful sun stars I mostly use my Voigtländer or some legacy lenses. So that wasn’t a big problem for me either.
The only weakness that bothered me from time to time is the flare resistance in terms of the red ring-shaped halo. If pushed hard, this can also be produced at cityscape shots at night but is only a real problem with strong light sources inside the frame — reframing may help a lot but can’t solve this issue in all situations. I think it’s caused by reflections on surfaces (of supporting mechanical structures and maybe the glass-air-interfaces) between the enormous front element and the second element. Maybe Samyang did its best, but still has to obey the laws of physics.
Focussing has always been a pleasure, but as with most EF glass I would wish for a dedicated aperture ring — which Canon itself was never a fan of after the FD-era.
As someone who always puts optical performance over weight the weight was no problem for me, but the CV or Laowa lenses are of course lighter (haven’t tried either one of those myself so far).
One tip for all interested in this lens: get the plastic front lens cap of the XP 14/2.4 as a spare part. It fit’s well (only in a certain position though) and can be locked to the lens in contrast to the provided slip-on metal lens hood.
In general I like this lens a lot — even if you need to give the RAWs some love in post due to the color cast and white balance issue maybe caused by the first — as it is capable of producing very nice views and has great optics. As with all UWAs: image composition may be a bit tricky with such wide views without getting boring/empty looking images. But as always with Bastians reviews: this man simply knows how to take very fine (ultra wide) pictures.
Thanks for the review!
