Thanks Todd! We appreciate the detailed overview. APS-C / M43 video shooters are typically big fans of this lens, and we're glad to hear you like it too!
I love sigma lenses. I am using art lenses like 35 and 85 on my 5d mark 3. Now I am planning to upgrade to R5. Thing is how can I use those sigma art lenses on my R5. Is there any adapter if I use adapter what about the image quality and focus options. Plz help
It's astonishingly good for filming. The weight and length are bonuses for hand held shooting. Right hand on camera, left hand on end of long lens. Stability and focus.
I use a Sigma Art 24-35mm F2 full frame lens with my Canon R5 in this crop mode but with a viltrox ef to rf speed booster (eliminating most of the crop) and a ninja V+ recorder. This essentially gives unlimited recording at a slightly tighter focal range but with 5k24p,30p, or even 60p in ProRes Raw at an aperture of F1.4 thanks to that speed booster. Absolutely love the results.
Just for information, cropping sensor is the same result than using crop sensor. So in fact on R familly if u crop, this lens is equivalent to 30-60mm F2.8. Juste a reminder ^^
Not really? Technically, it is as bright and has the same shallow depth of field as a full frame F/1.8. However, the smaller sensor size means that you have more noticeable noise and you're more zoomed in. That means that to have the same noise levels, you need to lower the ISO, making the image darker. Similarly, to get the same framing, you have to move further away from the subject and the further you are from the subject, the deeper the depth of field seems. However, the first point can be ignored because 4k video is such a small portion of the camera's sensor size and the second point, while you shouldn't ignore it, is actually negligible in the grand scheme of things. Comparing the price of this lens to Canon's other options like the 24-70 f/2.8, it is actually a really cheap and reliable option. However, if you spent ~$3,500 on the R5 and don't have enough for the 24-70, perhaps you should have purchased a less expensive camera a nicer lens.
@@ericlippe crop mod is using a part of the sensor. It's exactly an apsc field of view. Not 30-60 actually. Now we have muche better option because there is apsc on the R family.
There is a view that you also have to multiply the aperture by the crop factor when using such a lens on a full-frame body. Some tests with this mix have shown that the bokeh or background blur more closely resembles the multiplied aperture instead of the native aperture. So the "fast" argument for using this lens might not be completely valid if background blur is important.
It's true. The aperature must also be multiplied. That's why the lens is the same size as a 24-70 f/2.8. It is in practice a 30-60 f/2.8 because of the crop factor. That said, it is a great lens!

It’s a great lens on my R5 for video. The one other downside is the crunch crunch sound the lens makes from the autofocus motor. Other than that its pretty awesome.
@@ronr1094 I see all gear as a tool so while I’m not reckless it needs to hold up, and filters are always bearing the brunt of that use. My K&F NDs have stood up to that really well, as has my tripod from them. Very happy with both after 3 years of weekly use. I know other filters brands are very loved but I do think K&F should be in that conversation.
Almost one should buy this lens specifically for a FF camera. Like the author corrected in a comment and failed to mention in the vid, this is just a 27-53mm f2.8 when using crop mode. If you can use full width video without any obvious downsides, a 24-70 2.8 and shooting full width is just way better. Only two possible reasons I can think of are to avoid overheating or sometimes, to unlock higher feame rates in crop mode. If you have it already, its an option you can consider sometimes. But its certainly not "ideal" in any way shape or form. For APSC though this lens is still king, especially for the price! Works great on my R7, though needs to be said, with a slightly higher vudget, using EF f4L or 2.8L zooms + a speedbooster on it, you can often match or even surpass the overall performance of this lens, even on native APSC.
Hey Todd, thanks for the solid review! Got this for my R3 to replace the chunky 24-70 RF. Worth every penny and the autofocus and video quality is awesome.
Using the Sigma 18-35 with a viltrox speed booster on a Canon m6 mark ii is epic. Minor vignette on the 18 mm only (which i can easily manage by cropping in shooting from further away. Added benefit of Viltrox I t s now a f1.2 lense
It vignettes very heavily until 24mm. "Minor" vignette at 18mm is crazy to say lol, just not true. I own it too, it's great but no need to oversell it.
great review! i just purchased the film kit profile from your link on the m50 video last night! im glad i stumbled on your channel! great work as always!
How do you use a speedbooster with a crop-sensor camera on a full-frame camera? The crop-sensor camera should only fit with the 1.6x mode, but then with the speedbooster, its an extra crop.
I’m coming from a canon 7d mark 2. I want to keep my sigma 18-35 and 50-100. Which canon camera is best for video? I don’t want to buy new mounts. I’ll keep my canon 7d for portraits. Ty
I'm still debating if I should sell my sigma 18-35 and get 35mm f1.8 RF to retain full frame factor and more noticeable circle of confusion. I am using R6 btw, this video made me doubt like crazy, Maybe I should just have both I guess.
Just depends on what you use the lenses for. Honestly imo, that Sigma 1.8 18-35mm is good for 80% of non professional uses even on full frame so I'd only sell it if you REALLY need different capabilities and you aren't doing the typical workloads 😂 but whatever works for you is great
@@jbrowse09 I do not think the crop factor equivalent increases the aperture (i.e from f1.8 to f2.88), but it will give you the depth of field characteristics of a full frame lens with f2.8. You will still achieve the desired f1.8 low light on the camera compared with f2.8.
The "depth of field" will be less shallow but not because the 1.8 magically turns into 2.8, but because after crop you have to move the camera further away from the object to capture the same object, which makes it look somewhat similar to a smaller aputure, but it is simply how an 1.8 aperture would look like when the camera is further away from the object.
@@ericv4701 Exactly what you said. Plus the crop means that the individual pixels are bigger, which amplifies noise. That means to get the same noise level, you have to decrease ISO, meaning that it isn't actually as bright as a F/1.8
Yikes. I have a 90D and this lens and they are the most wholesome bread and butter!!! But I’m interested in jumping to mirrorless and selling my 90D at some point. Really sucks that this lens doesn’t adapt well for photos. Especially on a 24mp camera.
Good video. After seeing your video I am almost convinced, but I would like to know if the sensor stabilizer works with this lens. Thank you very much!!
Couple of important updates to this video: 1) I mistakenly assumed f/1.8 on this lens was equal to f/1.8 full frame. In terms of light gathering capabilities, the Sigma performs more like f/2.8 full frame. Still large, but not quite as big as f/1.8 full frame. 2) A viewer asked about autofocus noise when using an onboard mic. Tested noise with a Deity V-Mic mounted on top of the R5. Compared noise between the Sigma 18-35, the Sigma 24mm EF, and the Canon 24-70mm. All produced the same amount of "clicking" in recorded audio. I did have to crank the gain on the R5 all the way up to really hear it, but when comparing autofocus noise on the 18-35mm to other lenses, my copy of the lens was the same.
DXO Mark has it as an accurate T stop of F1.8, so it's a T 1.8, but depth of field eqiv of 2.8. www.dxomark.com/Lenses/Sigma/Sigma-18-35mm-F18-DC-HSM-A-Canon-mounted-on-Canon-EOS-760D---Measurements__1011

@@woohooproductions8741 That's good to know! It's such as great lens that it would be a shame not to continue using it on a new body (I guess I could give it to my gf to use on her A6400 if it was no good for the R6).

@@3VAudioVideo czcams.com/video/j8RfEuaKyfo/video.html EF-EOS R 0.71x -I found it on Amazon for $450. I updated the Firmware when I got it and works perfect!
Very persuasive... I'm a video guy shooting on a Blackmagic 6k pro and just got a Canon R6 for photos and videos. I was dead set on the Canon 24-70, so I can use it on both systems. After watching this, I'm back on the fence.
The R6 can't shoot 4k video in cropped sensor mode. Meaning that if you use this lens on that camera, you can only shoot 1080p video. Also, at a 1.6x crop, the r6's 20MP becomes 12.5MP when shooting stills, meaning that it is much lower resolution. I would recommend the Sigma 24-70 EF for a cheaper, yet more versatile option
Have you really stress tested the 4K crop mode in 24p with regards to overheating? I know Canon states that it doesn't overheat but I haven't seen any real tests online. The image looks so beautiful I'm even thinking about buying the Canon 0.71x adapter and use the 4K crop mode all the time.
Nice informational video. However I still use this lens on my SonyA1 and Sony A7iii for stills in non-crop mode. It's still usable at 29-35mm. I've had this lens since 2013 on my 70D and still use for both stills and video. I've found that updated firmware will cause the camera to automatically put it in Crop mode. Have gotten great stills out of this bad boy as a 35mm.
@@CrunchGaming for photo -> Canon L For video, go for 16-35 If u can save some money, wait a but and buy an 16-35 2.8, better in photo and very good on vidéo.
I've seen reviews from other BMPCC users talking about how well this lens performs as well. Crossing fingers Sigma releases a new RF mount version of this someday.
@@dominey Thing is, with EF, you can adapt it to almost anything. So you don't keep getting new lenses when you change your camera. With RF or E or any other short flange distance mount, you get very limited options, if any.
I wonder if this is all true on the R6... ?? If I could get around overheating in video crop mode on r6 and also not loss any video quality, that would be a game changer for me.
I have a Canon R5 and also the Sigma F1.8 18-35mm zoom lens. What you should know that taking a photo with a 45 megapixel Canon R5 in crop mode with an APSC lens will give you a file of approximately 18 to 20 megapixels and not 45 megapixels. So if you have a 20 megapixel R6 then I imagine the photo or video file will be much smaller so I imagine this is going to have a huge impact on the quality of the file given its low weight. Would have to try it because I don't have an R6, I have an R5.
First, the RF 35mm has the same aperture and low light performance, but is a prime lens, so you'd have to "zoom with your feet", unlike the Sigma 18-35mm which has variable focal lengths. Second, you can shoot full frame images with the RF 35mm (the Sigma creates 1.6x cropped images equaling 18 megapixels). Third, you can shoot 8K video with the RF 35mm (the Sigma cannot because "Movie Cropping" is enabled). Those are the main differences I can think of. As for adapters, I think they're definitely worth it, especially since there are far more EF lenses than RF (right now anyway), and EF lenses are typically cheaper.
@@dominey Thanks, I have both just still have no adapter and Sig is still new in the box as it was sold out everywhere. Dont plan on going in too deep into the EF line as there's only like 2 Zeiss Milvus lenses i want. Saving up towards the RF 70-200 f2.8
Technically? Yes. It will mount. However the lower resolution sensor of the R6 will even lower resolution images, and the video quality won't be quite as good because it doesn't oversample 8K when creating 4K.
Will the loud auto focus sound be heard in the video if you are using a rode mic attached to your camera ? And I know it’s manual focus so how would that work if you are doing a vlogging type of video, would you constantly have to adjust to focus ?
Don't have an EOS R to test this with, unfortunately. Assuming the R recognizes the lens as being a crop sensor lens, it sounds like Movie Cropping may be enabled automatically. www.manualslib.com/manual/1499201/Canon-Eos-R.html?page=219
i was test on my eosr good works but you must forget to shot on 60fps you must shot always 30fps video 😞.İ am wondering we can shot r5 with this lens 60fps?
I have an R- the crop is already 1.73x, meaning that it is more than cropped enough for the 18-35mm. It is a wonderful lens for that camera. Just make sure that you have an EF-RF adapter.
@@lvrvisuals7800 You're wrong. Sensor size only affects depth of field, not how much light is gathered. So this lens is in terms of how much light it gathers is 1.8 used in all cameras, but the equivalent depth of field changes depending on what you use it on.

So if you have a 20 megapixel R6 then I imagine the photo or video file will be much smaller so I imagine this is going to have a huge impact on the quality of the file given its low weight. Would have to try it because I don't have an R6, I have an R5.
Denis is right. The R5's higher resolution sensor is what makes this lens usable.
Does it work the same way with the R6?
has 10 bit 244 in cropped mode?
Hello I have a question, are you able to shoot 4k 120 in crop mode using the sigma 18-35 with R5
120fps is possible with Movie Cropping enabled, but the resolution is 1920x1080.
@@dominey We can shot 4k 60f0s with this lens?
Why use APS C lens on full frame R5
does your r5, overheat on 1080p 60fps cropped mode?
My r6 overheat at 45minutes of recording
Hey Todd, does the R5 allow slomo when working with the 18-35mm? I have an EOS R and with that lens it does not allow me to shoot in slow motion.
The maximum Frame Rate for the R is 30fps in 4k. Thats not lens dependant.
what is the maximum frame rate on full hd for canon r?
Tue sigma art 40mm is significantly better. Probably the sharpest lens on the market and almost perfect in every aspect except for the weight
Great video the filter is fire
how much?
How does it compare to the RF 35mm, want to know if its worth getting the adapter?
First, the RF 35mm has the same aperture and low light performance, but is a prime lens, so you'd have to "zoom with your feet", unlike the Sigma 18-35mm which has variable focal lengths. Second, you can shoot full frame images with the RF 35mm (the Sigma creates 1.6x cropped images equaling 18 megapixels). Third, you can shoot 8K video with the RF 35mm (the Sigma cannot because "Movie Cropping" is enabled). Those are the main differences I can think of.
As for adapters, I think they're definitely worth it, especially since there are far more EF lenses than RF (right now anyway), and EF lenses are typically cheaper.
@@dominey Thanks, I have both just still have no adapter and Sig is still new in the box as it was sold out everywhere. Dont plan on going in too deep into the EF line as there's only like 2 Zeiss Milvus lenses i want. Saving up towards the RF 70-200 f2.8
Great Sigma Vlog, thanks for sharing
How much focal length on r5 with lens
Does this work on the R6? Thanks for the video!
Technically? Yes. It will mount. However the lower resolution sensor of the R6 will even lower resolution images, and the video quality won't be quite as good because it doesn't oversample 8K when creating 4K.
Will the loud auto focus sound be heard in the video if you are using a rode mic attached to your camera ? And I know it’s manual focus so how would that work if you are doing a vlogging type of video, would you constantly have to adjust to focus ?
Interesting question. I’ll give it a shot and see.
Follow-up - check my pinned comment at the top of the thread.
Hi, can I ask how this would work on the EOS R? The 4K is already heavily cropped on that. How would that work with this lens?
Don't have an EOS R to test this with, unfortunately. Assuming the R recognizes the lens as being a crop sensor lens, it sounds like Movie Cropping may be enabled automatically. www.manualslib.com/manual/1499201/Canon-Eos-R.html?page=219
i was test on my eosr good works but you must forget to shot on 60fps you must shot always 30fps video 😞.İ am wondering we can shot r5 with this lens 60fps?
I have an R- the crop is already 1.73x, meaning that it is more than cropped enough for the 18-35mm. It is a wonderful lens for that camera. Just make sure that you have an EF-RF adapter.
How would this lens work on a m 50 with a speed booster?
It’s not ment to be used with the speedbooster because it’s an APSC lens, so if you put it on the speedbooster, you’ll get huge vignette till 24mm.
As a downside you also forgot to say that Sigma 18-35 f1.8 it has no Image Stabilisation .
R5,this lens is good for still photography?
I don’t think so. I mention this in the video, but this creates cropped, lower resolution photos on the R5. Works well for video tho.
have you tried this with a m50 speedbooster with it?
an m50 already has a 1.6x crop, so you can't stack a speedbooster on top of that.
You can use it as 35 full frame. When it’s at 35 it covers full frame
I have it,
on my 5dmkIII, i have vignette even at 35mm
It should be noted that an f1.8 crop is roughly equivalent to a f2.8 full frame when it comes to depth of field/Bokeh, but otherwise a great video 😃
No. The incoming light does equal around F2.8 but the bokeh and DOF does not change. Only exposure wise it changes.
@@lvrvisuals7800 You're wrong. Sensor size only affects depth of field, not how much light is gathered. So this lens is in terms of how much light it gathers is 1.8 used in all cameras, but the equivalent depth of field changes depending on what you use it on.
IBIS working on R5 with this Lens?
Internal IS, yes. The lens itself doesn’t have optical IS but you can use the R5’s.
👍🏾🙏🏾
As MUCH as I loved this lens on my APS-C cameras I didn't pay $4k for my R5 to use it in crop mode LOL.
Lol - I know what you mean.
It’s a good lens but why waste sensor space and use a crop lens on a full frame sensor
