Great reasons! Didn’t realize it was parfocal. And completely agree with sharpness. You can always make a sharp lens not sharp. But a not sharp lens can’t really be made sharp!
Thank you so much for your kind words and support! Yeah, I was surprised to find out that it is par focal too! And yes, that’s why I prefer a sharper lens to begin with unless you want a specific softer look like on vintage lenses.
Hi Henry, Thanks for the parafocal tip! I’m using the Canon R5 but using a metabones speedbooster for my EF primes, 35 and 85/1.4. I am debating between Canon’s 24-70/2.8 USM ii vs Sigma’s for both stills and videos. Have you done a comparison between the two and what the tradeoffs are?
Just use your crop factor multiplied by focal length. Doesn't matter the model. All APS-C cameras are 1.5x (apart from Canon 1.6x). So in 4k30 you have 36-105mm f/4.2 equivalent. If you shoot in 4k60 which is a 1.18 x 1.5 = 1.77x crop, it becomes 42-124mm f/4.9 equivalent. If you use 1.29x crop fix, 1.29 x 1.5 = 1.94x. It almost behaves like a micro four thirds, so 47-136mm f/5.4. The equivalent apertures are for depth of field relative to full frame. The exposure will still be f/2.8.
The Sigma 24-70mm for Sony doesn't have Stabilization, I wonder if I got the EF version and then used an adapter, would it retain all the AF features + Stabilization?
i want the sigma 24mm 1.4 and the 18-35 and the 24-70 and the 70-200 all from sigma i love what i'm hearing from them so i want to start getting these camera lenses. i really like what i see so i want to know how good sigma art series is. henry can you help me with a good flash to go with my camera?
Hi bro, great video! Last year I bought the same lens Sigma 24-70mm, seriously good lens and also, I have the same BMPCC 6K, but I do not know how to use that parfocal thing, cause any time when I zoom out or zoom in it's not AF and stays out of focus. Can you please advise me? Just upgraded my BMPCC to a new version 7.9. Cheers and thanks! ;)
Every source I can find says that this is not a parafocal lens. What is your source that it is? In your test it looks like you have AF on for the zoom...
This was VERY helpful. As a (total) beginner who never used cinema cameras before, I was wondering what lens to get first for the BMPCC6k, for both indoor and outdoor use. Looks like the 24-70mm f/2.8 is a no-brainer here. The only nagging doubt I still have is if it will be good enough for night scenes, e.g. in dimly lit streets... or if a f/1.8 or f/1.4 lens would be unavoidable. Not sure yet about high ISO performance of the BMPCC6k. Will have to try it our once the 24-70mm arrives. Keeping my hopes high.
That’s a great question! We have never used the Metabones speed booster before, but since this is a full frame lens, it should be better when it comes to vignetting. Hope it helps! Thank you so much for your support on the video!
That’s a great question! The focus ring is stiffer than the Sigma 18-35, definitely not as light, but still smooth. Hope it helps! Thank you so much for your support on the video!
@@henrymediagroup That is actually great to hear! I am really thinking about grabbing this lens but wasn't sure if it felt really mushy compared to the canon 24-70
I contacted B&H and I asked them what's a good lens for use on a BMPCC 6K in a podcast where the camera is about 3 to 8ft away. How do you feel about that?
You are very welcome! We have been adapting the lens to the BMPCC4K and the GH5 using the Viltrox speed booster. So far everything works except if we update the speed booster the BMPCC4K cannot display or control the aperture of the lens. Hope it helps! Thank you so much for your support on the video!
So, I have this lens with a Pocket 4k and MB .64 and it is not even close to par focal. Any advise on whether this can be fixed? The lens is cool for the most part but that is a huge gripe I have.
That's a great question! I have never adjusted a Metabones speed booster before, but Gerald Undone has a great video on how to adjust the speed booster to help making the lens parfocal, you should check it out! I adjusted my Viltrox speed booster and it works fine. Hope it helps! Thank you so much for your support on the video!
That’s a great question! If you do a lot of spontaneous filming that doesn’t allow you to have time to setup, and you usually film in a bigger open space, the 24-70 is a great choice because of its range and image stabilization. If you usually have time to set things up and you are always filming in a tight space, 18-35 will be better because of its wider angle. Hope it helps! Thank you so much for your support on the video!
Yeah, I was surprised that it is parfocal too! If you are using a speed booster, you can adjust it to help making your lenses parfocal. Thank you so much for your support on the video!
Thank you so much for your kind words and support! That’s a great question! We have never used the Metabones speed booster, but I remember Gerald Undone has done a video showing how to make the Metabones speed booster par focal. With our Viltrox speed booster, we just need to carefully turn the glass, mount it back onto the camera and keep repeating the process until it is par focal with the lens. Hope it helps!

Hey! Thanks for the great information. btw, I'm a canon crop mirrorless user(m6 mark2) and I'm thinking to get this lens. (also I was considering maybe get a sigma 50mm/85mm art. If I don't buy 24-70 lens) Would you still recommend me to get this or...is there a better option? I little worry about the weight. I'm not quite sure if my camera can hold this lens.
You are very welcome! I’m glad that you found the video informative! If you are planning to stay with APSC Canon cameras, this lens will definitely be very heavy for your setup. Sigma does have many lens options for APSC cameras, but unfortunately we have never tried them ourselves. Hope it helps! Thank you so much for your support on the video!
This lens isn’t focus by wire but to answer part of your question, focus pulls on a focus by wire lens is very difficult and unpredictable. Hence why I’m selling my 24-70 canon RF for this lens.
That’s a great question! We haven’t had any dust issues with the lens maybe because we use it mainly indoors. Hope it helps! Thank you so much for your support on the video!
That’s a great question! We have never tried the Tamron 24-70mm but we heard good things about the lens too. The only thing is that someone did mention the lens not working well with the BMPCC4K or 6K. Hope it helps! Thank you so much for your support on the video!
Thank you for the suggestion! We will try to get our hands on the GM lens, stay tuned! The image quality of Sigma Art zoom lenses are almost as sharp as primes! Hope it helps! Thank you so much for your support!
You are very welcome! Unfortunately we don’t have a Fuji body at this moment to test out the lens, but hopefully we will get our hands on the Fuji system soon! Thank you so much for your support!
Is that a sigma art ? I have heard that sigma lenses looses it’s sharpness with 1-3 years of use (I’m really afraid of that), and other horrible things about it lol what has been your experience with sigma?

Love how you started this video right off the bat with it being parafocal. I've never seen a non cine lens have that!
Great reasons! Didn’t realize it was parfocal. And completely agree with sharpness. You can always make a sharp lens not sharp. But a not sharp lens can’t really be made sharp!
Thank you so much for your kind words and support! Yeah, I was surprised to find out that it is par focal too! And yes, that’s why I prefer a sharper lens to begin with unless you want a specific softer look like on vintage lenses.
I literally just sold 3 of my lenses to buy this one , I use it 90% of the time, Great Lens
Thank you so much for sharing your experience and supporting the video!
Great job
Thank you so much for your kind words!
Hi Henry,
Thanks for the parafocal tip!
I’m using the Canon R5 but using a metabones speedbooster for my EF primes, 35 and 85/1.4.
I am debating between Canon’s 24-70/2.8 USM ii vs Sigma’s for both stills and videos. Have you done a comparison between the two and what the tradeoffs are?
Great vid !!
Thank you for supporting the video!
Great video Henry! Question, if I use it with my Fujifilm x-t4 (w/ fringer adapter) what will be the focal range equivalent?
Just use your crop factor multiplied by focal length. Doesn't matter the model. All APS-C cameras are 1.5x (apart from Canon 1.6x).
So in 4k30 you have 36-105mm f/4.2 equivalent. If you shoot in 4k60 which is a 1.18 x 1.5 = 1.77x crop, it becomes 42-124mm f/4.9 equivalent. If you use 1.29x crop fix, 1.29 x 1.5 = 1.94x. It almost behaves like a micro four thirds, so 47-136mm f/5.4. The equivalent apertures are for depth of field relative to full frame. The exposure will still be f/2.8.
Have you ever compared the OS against the tamron G2 perhaps?
I'm very glad I found this video and this lens. I preordered the BMPCC6k PRO and I was looking for my first lens.
That’s awesome! I’m excited for you too! Thank you so much for your support on the video!
It was really helpful.. I was just looking forward to get this. thanx.. 🙂👍👍
You are very welcome! I’m happy that you found the video helpful! Thank you so much for supporting the video!
Thanks for the video. Can you tell me what is the brand of the focus ring that are attached to your lenses. Can it be used for any lenses ?
Great work!
Thank you so much for your kind words and support!
The Sigma 24-70mm for Sony doesn't have Stabilization, I wonder if I got the EF version and then used an adapter, would it retain all the AF features + Stabilization?
Great video mate. Do you have a video showing more examples of the OS on different focal lengths/subjects/movements?
Thank you so much for your kind words and support! Thank you so much for your suggestion as well! We will try to make a video on that!
@@henrymediagroupdid you ever make a video on this? Trying to figure out whether the OS will be OK for follow/tracking shots.

Can i somehow use it with canon m50,? till i get my sony a7iii
Is lense compatible with black magic pocket cinema 4K ?
What’s your opinions of this lens paired with the bmpcc4k and metabones… you think there will be any vignetting on the wide end?
That’s a great question! We have never used the Metabones speed booster before, but since this is a full frame lens, it should be better when it comes to vignetting. Hope it helps! Thank you so much for your support on the video!
the .71x meta bones won't vignette
How is the focus throw on this lens? Is it fairly similar to the sigma 18-35 in terms of stiffness?
That’s a great question! The focus ring is stiffer than the Sigma 18-35, definitely not as light, but still smooth. Hope it helps! Thank you so much for your support on the video!
@@henrymediagroup That is actually great to hear! I am really thinking about grabbing this lens but wasn't sure if it felt really mushy compared to the canon 24-70

@@henrymediagroup thinking about getting this for my GH5. What's the equivalent focal length when speedboosted? 12-50?
which zoom and focus ring did you use?

@zakkbeaty Did you solve this issue? I’m considering this lens for use with the MB .71 on Pocket 4K. Thanks!
even though it's a crop sensor lens i can still use this 24-70 on my canon 80d right
Hey, Henry would you recommend this lens for a documentary shooting with the Blackmagic Pocket 6k? I already had the 18-35mm sigma lens in mind.

whaaaaat i had no idea it was parfocal! thats why i love the 18-35 because its ALMOST parfocal😂 i think that alone just sold me on the 24-70😍
