- A review of the Sirui 1.25X Anamorphic Adapter.
I thought this was going to be a simple, fun review with some sample footage. Through many tests, on various lenses, I had mixed results and feelings. A very difficult review but a journey nonetheless!
It's worth watching for my final conclusion, it was the first time I had a plot twist that I wasn't expecting.
Some of the lenses tested with the Adapter:
Canon EF 1/2L / 50mm EF 1.8 / EF 80-200mm 2.8 / EF 100-300mm L 5.6 /
EF 85mm 1.8 / Sirui 35mm APS-C / Sigma 50mm 1.4 art / Sangyam EF 35 T1.5 / Meike 25mm T2.1

First I must commend you on the actual presentation and making of this review, very nicely done. The journey with a plot twist was a fun ride. I'm having a similar experience with the adapter where the results really depends on the taking lens. Appreciate the mention and looking forward to part II.
Thanks, I look forward to seeing your videos also!
Such a great review. As always. Informative and interesting. Love your channel!
Thanks, a really tricky one but I’m glad I stuck with it 👍.
Couple of things you need to realize when using adapters. It’s not always going to work the same in a lot of lenses and this has a lot to do with either one of a few things. How many lens elements the lenses has, how sharp the lens is and also what the front element of the lens looks like. Light has to pass from outside the lens and travel all the way through to hit the image sensor. Lenses themselves are design to try to keep that light bream as sharp as possible when traveling through the back of the lens, of course more expensive sharper lenses do it better. When you add an adapter like this you are adding and extra element that complicates things. Also adding another element to the element count also complicates things. For example telephoto lenses like 70-200mm 2.8 already have around 13 elements to go through, because of this they are also prone to side glare and bad flaring that can effect image quality, adding this adapter can just compound the effect. Also adding a Diopter is another issue. On most of them the quality and coating on the glass isn’t the greatest to that’s going to effect quality. Lastly in your issue with the sigma 50 also the way the front element is shaped can effect the light traveling from the adapter to the sensor, for example the curvature of the front element can throw things off.
Thanks, for the info. All good things to bear in mind for sure. Strange that the cost as I've seen isn't always a defining fact as much as the lens design itself. Either way, my experimentation continues!
Interesting review. While I am not a user of anamorphic lenses, I enjoy your presentation style and critical discussions. Thumbs up!
Thanks for watching 🎉
Great review! I had same mixed feelings, until I've tried it with my Tamron 45mm 1.8 SP. Boy, sharpness and out of focus background were beautiful. Some nice anamorphic image coming out of this combo. Yes, there's still some green tint halo at times, must be kept under control. The closest it can get to the taking lens, the better.
When I do my follow up I will mention that I did get another version and this seems sharper overall. But I've not yet had a chance to do more testing. Thanks for your comment!
Super helpful! Great job! Thank you!
Thanks! Btw I did a follow up video with more info.
Enjoyed watching your journey with this adapter ! Thanks for sharing
Thanks for watching 👍
I love this vid and I just wanted to say that this is really cool and I love this vid!
Thanks!
Really interesting watch and a very thorough and engaging review. I had high hopes for this adapter and it’s a shame to see that it doesn’t quite produce the same results on all lenses
Thanks for watching! Yes I feel the same defo needs to be tested on lenses before use, but when it does work it looks great 😀!
Very useful video with practical usage. Thanks for putting this out. Sounds like you'd want really sharp glass like Sigma Art to pair with this and get normal sharpness. Might work with my Meike Glass for a really artsy soft look.
Yes, I did try the 50mm sigma art which worked well and that’s what I used for the end vlog. Now that I’ve figured out what the lens is and isn’t I look forward ti using it more👍.
Thank you. Very informative. Subscribed.
Wonderful review, easy and simple to grasp!! Which diopters are you using? Been looking around but can’t seem to find trusted ones. Yours seems to be working very well with no artifscts, color shifts or softening.
Thanks for the feedback. I can't seem to find the purchase in my history, although I'm sure I bought it from Amazon for around £40. I've heard good things about K&F branded diopters via a video from DSLRguide (title of the video is - my favourite camera gear for under $30)
Any other questions, let me know! BTW I will a update for this video soon, I've just not been able to put it together yet.
@@minutesback Ok, i will definitely check K&F up. Can’t wait for the update, i all of certain got interested in anamorphic glasses hahah, i mean I’ve always been, but prior the ones available were $10K+, so you just act like you don’t need them lol.
Thanks again, your time is really appreciated!
Perfect for the S5II or S5IIX, as the softness will help the almost too sharp image sensor.
Nice video, keep it up. Fun fact: While this adapter (or any for that matter) can be used on many different lenses; the distance from the outermost lens element of the taking lens will effect its performance… sharpness, chromatic aberration etc… I don’t believe there is an issue with your adapter, just the spacing is incorrect.
Do you think it might be the step up rings that might be causing the issue?
@@minutesback Its best to use a single step ring from adapter to taking lens. Stacking 2-3 separates the elements apart and will definitely make the image less sharp.
@@PatrickBishop1 I thought but it didn’t work that way with adapter, some lenses I mention with multiple worked better than some with single rings. Some single step rings didn’t work at all.
I noticed the stack of filters you had between the lens and adapter, does that not act like a macro tube , therefore effecting the focal range and dof? Did you test with and without and get the same results?
I tried various combinations and it was the same I only took photo of what was on at a particular time. I assume you mean step up rings and not filters I didn’t use filters. I only used some diopters and tested with and without.
In the end I got them to make me a custom one which is perfect and I really love it. I think Sirui have an early production problem as I’ve had 2 duds from them, both which they have corrected but their marketing team is awful now.
@@minutesback ah yes, step up rings! Appreciate the review, it's proper💪🏾
Perhaps the ability to get accurate infinity focus on the taking lenses is impacting sharpness? Some lenses focus just past infinity to allow for tolerences in different temperatures etc?
Yes, I have found tweaking the infinity focus on the taking lens to help on some lenses. However, I have since got a new adapter, and it is sharper. Also, Sirui has ghosted me on emails, so I think there are some issues they want to ignore.
Thank you - I have a new adaptor still in the box and was considering whether to sell it or keep it to put it on my Sirui 50mm 1.6x.
I hadn't really considered fitting it to the 4 Samyang lenses I use on a Canon C200. I think I'll keep it 😀
First tests are that it's horrible on the 24mm but good on the 35mm.
@@destinationnew from what I found it worked best from 35 up to about 85 or 100mm. How sirui told me it should be able to go up to a 135mm. Also, I sent mine back for a replacement and my new glass was sharper. I personally think they had manufacturing issues.
@@minutesback Thanks, I have the Sirui 50mm 1.6x, so I’m not too interested in that focal length, but I will try it on the 85mm tomorrow.
@@destinationnew I look forward to hearing your results!
Is the adapter the correct distance from the lens with all of those step down rings?
I did experiment with various step up rings I did get some single step ups but didn’t photograph everything
Please tell me how things are with the canon 24-70 2.8 lens, at a focal length of 24mm??? You have only touched 70mm. Very interesting other focal lengths on this lens with this adapter!
I did use on a 24-70 EF but I think I had to zoom into around 35 ish else there was a bit of vignette.
@@minutesback Thanks for the answer and for the review. In fact, is it possible to use this adapter starting from 35mm on this lens?
@@Edgar86 yes I bought 35mm prime which works great. The adapter I’d say works best from 35-135mm.
What causes the softness issue is actually simple: physics. The Sirui anamorphic adapter uses a variable diopter for focusing, and no manufacturer can make a diopter equially suitable for all lenses. Diopters are always optimized for a certain focal length, so for versatility, DIY anamorphic setups require several diopter-based single-focus solutions. In this case, I suspect the diopter to be optimized for 50mm taking lenses (would love to hear the accurate info from the manufacturer).
I sent the one I had back and the new one looks sharper so build quality makes a big difference. I will do an updated review at somepoint but waiting to hear back from Sirui. I defo think there was a bit of an issue with my last version.
I’ll probably buy one or two of their lenses for Fuji X. The adapter seems to suck.
A few days ago I cheated a little and put the Viltrox 13mm on the Fuji and cropped the image. Because of the f1.4 it does look like a 35mm f2 anamorphic, but without the anamorphic artefacts of course.
If I could just get a filter that would give me some of the artefacts (oval bokeh and horizontal flares), without destroying the image sharpness, it would look amazing.
I mean when I got to work on a lens like the 35mm I really liked it plus since the video they changed it over and the adapter is sharper. Will do an update video but for now I’ve been busy. Wish you all the best with your cinematography!
Adapter normally doesn't work well with zoom lens, lens with large front element and telephoto lens. My copy works well even with a vintage lens Helios 44m with no flares at all and decent sharpness wide open. The adapter world is indeed more hassle to work with. I have used great joy 1.35x adapter which is a little bit sharper and more characteristics.
Really good to know! Thanks for sharing that information! I had to thought to go with Great Joy but decided on Sirui as I had bought from them before... Defo not clear cut now for purchases in the future 😇.
Thank you for this review! I was about to buy this adapter to use it for photography project with VarioElmarit 24-70 but it definitely will not suit my needs… looks like i will better buy Sirui 135mm .
I’m a little late on an update as I got a replacement which I will be talking about soon… however the 135mm I’m sure will be an excellent option either way.
Interesting video.. i just became a fan..
I do own Samyang Cine mk2... and i am looking to buy this adapter...
so.. With Samyang.. This Adapter will work perfectly??? according to "The Ending Of This Video" lol lol
Yes, it's a great, that lens with the adapter. I've got an update coming soon as I got my adapter replaced, and the new batch of adapters are much sharper but watch this space 😇😊
@@minutesback So.. This Adapter.. with My Samyang Cine Lens MK2... IS A REALLY AMAZING COMBO??
I was going to hold off and same more money to buy the "Moment 1.33x" Adapter...
@@tonysluna have you got it or are you still thinking about it?
@@minutesback i have not gotten it iyet.. but.. your video.. Convinced me...
it would work with my Samyang Cine mk2 Set...
this will be my 1st try into Anamorphic ...
Do you have any suggestions...?
@@tonysluna I bought the cine mk 1 35m and it worked great plus I bought it 2nd hand. Similar to the one I used in the video but the first version
Dear MinutesBack, excellent video and discussion regarding the Sirui 1.25X adapter. I also picked one and had the same difficulties that you described in your video. After some experimentation with it, I think I have found the explanation the variability in sharpness that you have experimented. My understanding is that two issues play into consideration, one is surly the sharpens of the taking lens, but this does not explain the variability, the second issue is critical and is the precision of the taking lens to focus at infinity. You see, this adapter demand that the taking lens be precisely focused at infinity and say put at the position. Even a minor deviation of 1mm will cause the type of image degradation that you have experienced. I tried this lens using some isco red projector lens and racked the focus at infinity as precisely as I could and the results were very good. See the video ruclips.net/video/pY3m8zO07Ks/видео.html
Says the video is private? Will you be doing a review?
@@minutesback Sorry about that, it is now live. This video is not a review, exactly, but some footage that I took with this adapter and some spherical projector lenses from ISCOs. Initially, I had tried it out with a Canon 24-105 and a 70-200 and my impressions were like yours. To be frank I was a bit disappointed with the performance that I was getting from this less. But it was when I decided to try it again and decided to use a projector lens e see your it worked that I understood how critical focus in infinity plays a critical role. Even a very slight deviation in the flange distance can be very detrimental to the image quality. I definitely intend to make a video trying to demonstrate that in the near future.
They are made for primes. The longer the barrel of elements the worse the performance.
Yes in the video I tested quite a few prime some performed better than others, if you watch my follow up video you’ll see that their was something wrong with this version which got replaced.
Intertesting. I will have another look. I have noticed that with my version, there to be only issues with instances in which I did not completely set infinity focus on the take in lens. I tested on Helios 44, Mamiya 645 80mm, Sirui nightwalker 24mm all pretty perfect. It was always important to as well check peaking to ensure focus was achieved. Really like the results for motion.@@minutesback
@@anthonyrock5039 with or 2 instances I noticed I had to move focus just before infinity and then sharpness increased. Obvious on that occasion it is the taking lens and not the adapter lens. 👍
I have seen with some other people, issues also came up with some lenses due to over extended step up rings.@@minutesback
Sirui is green, atlas is green, all the lenses has their own color signature... if you dont want it send it to me :)
In fact the other lenses I have of theirs all have blue streaks.
pretty annoying.
Which bit?
