[@Invisionaires]

if the sigma is a taller lens wouldn't that play a factor in it having that slightly having a slightly different result at 6:53 ? assuming you just kept the tri-pod in the same spot the position of the front of sigma's lens would be farther forward than the sony lens by the difference in comparative focal length?

[@MatthewGore]

Not at this distance, which is at least 150 meters to the opposite side. As a percentage, an inch (2.5cm) is nothing at all... and in fact, the optical opening of the lens is somewhere in the middle of the lens, so the actual difference in length would be less than an inch... maybe 1/2 inch.

[@marramraabe]

Awesome to see you back again, Matt! And although a somewhat truncated review, very interesting - thanks!

[@MatthewGore]

Glad you enjoyed it :-)

[@neohsoonsien4007]

Thanks for your review... A very fair comparison for both... I already owned 85mm f1.8.. Just thinking of getting the Sigma 24mm f1.4 in the future...

[@DTaylorYoutubeChannel]

The F4 issue mentioned in this video doesn't exist on my copy of the sigma art 24, maybe a firmware update has removed the problem

[@MatthewGore]

Awesome, thanks! Don't suppose you have a few RAW files I can look at? (Of the same scene at f/2.8, 4, and 5.6) I'd love to see what this looks like when there's no problem.

[@shaolin95]

Sony has really stepped up their lens design with the smaller GM beating the much larger Sigma. Same with the 135mm

[@MatthewGore]

Agreed. I've been really impressed with their lenses, recently... and it's especially impressive because the engineering is a little more tricky with the smaller mount and shorter flange-focal distance.

[@TheEryk03]

And much more expensive...

[@shaolin95]

@@TheEryk03 if you cant afford it buy something else .obviously quality does not come cheap

[@navpreetsingh8156]

The Sony is also much newer and designed for Sony, the Sigma is really a Canikon lens

[@fellowcitizen]

The shorter flange of the L+E mounts allow for far better size-to-performance values for wider and mid lenses (only slightly for longer lenses) so the new line of Sigmas designed for the fp, SL2 and S1/R/H will be smaller +/- sharper like this. As of OCT2019 Sigma has released a compact 800g 14-24mmF2.8, an even more compact 45mmF2.8 at 215g, and a large 1.1kg yet unique 35mmF1.2 (first ever with autofocus) which would have been impractically huge if built for reflex cameras. This particular Sigma is known to be the weakest in the ART series by a large margin, with some photographers preferring the ART28mm if they don't need as much range since it noticeably exceeds the Zeiss Otus ;) www.lensrentals.com/blog/2019/03/mtf-results-for-recent-sigma-art-lenses/

[@eccentricsmithy2746]

How can you shoot at 16 bit listed at 1:31 when the A7R3 highest bit rate is 14?

[@MatthewGore]

I shot as 14 bit RAW, processed as a 16-bit file in Camera Raw, rather than 8-bit.

[@RicardoEsteves]

Are these lenses compatible with my a6400?

[@MatthewGore]

Yes, they both are.

In the end we've chosen the Sony GM also thanks to this video. Going to use it as fast as we can.

[@i_am_pasha_shin]

Nice comprehensive review I've been using 24mm GM for a while and have never experienced that issue with the aperture ring on Sony

[@stefantotev]

Thank you very much for this great review and comparison! I have had the 24art and used it on a7r III but sold it after the GM came out. I wanted to get it due to the size and weight difference. And also the AF speed in video. If you have the 16-35 GM and 24-70 GM could you please make a comparison between them and the 24 GM at 24mm please? 🙏 Or if you don't have the time, can you respond here with your observations about it? It will be much appreciated! I am still deciding on whether I should get the 24 GM or not. It's very expensive in Europe and I already have 16-35 GM and 24-70 GM (which I've been trying to sell for a long time, because I also have the Tamron 28-75). But I really like a fast 24 and it is fantastic focal length for video, so I think I need one in my kit. It's just that I don't like to have lenses covering the same focal length... so I'm still debating.

Thanks! I just got a Tamron 17-28 f/2.8 for Sony, which I'll be testing against the Sigma 14-24 f/2.8, as soon as it arrives. I'm also curious about the new Tamron 20, 24, and 35mm primes... I'd like to see how they compare to the Zeiss Batis 25mm, for example. And the Tamron 70-180mm f/2.8 for Sony is at the top of my list.

[@dlee13]

Matthew Gore I look forward to seeing those reviews! If only Tamron he released f/1.8 primes, I’d love the 24mm in that case. I got the FE 35mm and always used 35mm but been curious about the 24MM Gm ever since I tried it 😅

[@frankfeng2701]

24GM = best-value all-round wide angle prime of all time?

[@tallaganda83]

Maybe the best prime, but I wouldn't call it value, its super expensive.

Hi my purpose to buy lense is video....... mainly short films.....which one will be best?

[@rcquinn1]

I'm not sure what you mean about being able to inadvertently move the aperture ring off "A" to the f 16 spot. Mine is stiff to move from the "A" into the manual part of the ring. I don't know if you had an older or maybe a damaged model but accidentally moving if off the auto position is not an issue.

[@MatthewGore]

Ahh, well... I'm glad that it's not a problem for you. The ones that I've used have all been about the same... it was a pretty light touch to move it out of the "A" position, or to any other position... about the same as my other lenses with manual rings. It's an easy fix, at worst... but unfortunately it was not an uncommon occurrence for me.

[@rcquinn1]

Thanks for the reply. Yes mine is a pretty positive click to move it out of that position even with the click switch set to off. I got mine yesterday after about 6 weeks of waiting. Maybe Sony addressed the issue on the newer lenses. Thanks for the review.

[@patryklason3108]

Hello, Can you get any information about what software was used in this lens when the test was performed? Now is firmware version Ver.02 2019.07.18, is the problem still at F / 4.0?

[@backyardjunkie]

First time here Matt, excellent review and comparison. Those river shots at beginning looked awesome. I'm still undecided on the 24mm or 35mm .... Only so much cash to available. Have subbed and liked.

[@FreddyGMedia]

any word back on the f4 issue for the sigma lens? I'm contemplating which 24 to buy next and this is def a deal breaker if there is/was no fix. Although I don't shoot at f4 much, a lens should not be that blurry at that aperture.

[@MatthewGore]

Sigma USA told me that they had escalated their investigation to Japan, but I haven't heard anything beyond that. If you've seen my video about the Sony and Sigma 135mm f/1.8 lenses, you'll see that I ran into the same f/4 issue with that Sigma. In both cases, I asked people to check THEIR lenses and see if it was a problem with my Sony A7RIII or something (though, obviously it's not a problem when I use Sony lenses...), and nobody ever responded (except for one guy who said his Sigma was fine, but wouldn't give me any example files to check for myself). So, I just don't know. That said, Sigma is sending me a couple of lenses next week. It seems pretty clear that if it's an issue with the Sigma lenses, it's a firmware issue... so this should give me an idea of whether this is something that they've addressed in the past year.

[@FreddyGMedia]

@@MatthewGore yea, I saw that video as well because I eventually want the 135 also but I do more video work and find myself using my 16-35 gm at 24 A LOT so it's more practical for now to purchase a 24mm. I still find 2.8 not to be fast enough for my needs although for certain shoots it's more than fine. I would love an update once you get those lenses, I wish I had them to test as well because I would. Are you planning on a video when you receive them?

[@MatthewGore]

@@FreddyGMedia I will be doing videos on both of the lenses, yes.... but I like to give my lenses a good, long, thorough testing before making a review, so don't expect the videos for at least 6 weeks... probably longer, since I also have an upcoming trip to Japan that will be taking up a lot of my time. Sorry! But I will at least know whether there's an f/4 issue with the two lenses within the first few days of testing them... so I'll try to come back here and update you. Remind me in a couple weeks if you haven't heard from me.

[@marchonore]

It would be helpful if there was a table of contents.

[@MatthewGore]

Done.

[@davey1321]

Is it possible that the sony is slightly wider because it is shorter in length, and thus the edge of the lens barrel sits a few inches further back than the sigma?

[@MatthewGore]

Hi Dave. In this case, not really. There are a couple of reasons, but the most important one is that the distance to the opposite side of the waterfall was 600-700 feet, so the difference of 1" difference would be insignificant in the overall distance. I could probably have stepped back a several paces and, at that distance, the angle of view would would not have changed noticeably (though, of course it would make a distance on closer objects). Also important is the fact that the angle of view doesn't begin at the front element of a lens, it begins somewhere in the middle of the lens (depending on the lens design) where the image is focused down to a point and then flipped over. The measurement point is called the "optical opening", and this may be towards the back of the lens or in the middle... and may be exactly the same for these two lenses, or it could be even greater than the inch difference in lens length. If we were measuring angle of view on a closer object (a wall in the same room as the lens, for example), then it would be much more important to find the exact location of the optical opening of the lens and measure from there.

[@tomasturis8909]

@@MatthewGore it's some weird kind of decentering or something like that, this is not exclusive to your Sigma. was it on whole image area the same? try comparing also sides etc possibly

[@MatthewGore]

@@tomasturis8909 Remember that this was only at one aperture setting; decentering would affect the lens beyond f/4. You can download the RAW images and look at them yourself, if you're curious, but the blur is across the entire frame. When I returned the lens to Sigma after testing and told them about the problem, the techs started trying to figure out what the problem was, and I gave them about 25 RAW images to check, with f/4 being bad in each case. They still haven't come up with a definitive answer yet. I still suspect a problem with the electronics in the lens and the IBIS system in the camera.

[@DTaylorYoutubeChannel]

I own this lens I own this lens also and I've never had any focusing issues on any aperture. No problem at f4 on my copy either

[@wow.fotoschool]

Вы считаете Sigma намного хуже ? Стоит переплачивать? Или разница не так уж велика?

[@Ktb_Contract0r]

Couldn't the difference in angle of view be accounted for with the difference in the length of the lenses?

[@MatthewGore]

A good question, but no... I don't think so; the distance in the length of the lenses is insignificant compared with the distances involved to the subject here. The subject (well, focal plane) was at least 150 meters away... so the difference in lens length of the lenses ( 1" or 0.025 meters) is not a significant (0.00016%)

[@ousi00]

One interesting difference that might matter to videographer is focus breathing. Sony has quite a bit of focus breathing while the Sigma is much less. It looks like Sigma at f/4 is strange. Electronics I would say...

[@Sentimentmedia234]

One thing that you've missed is video AF, on the Sony it tracks well and smooth while on the Sigma (like all Sigma lenses on Sony emount), the focus transition and tracking not smooth at all and is prone to abrupt stop.

It all depends on your needs. They're both excellent lenses, optically, but you'll get more zoom range, more weight, and more cost with the 16-35m. It depends on which of those factors is most important to you :-)

[@zollieuncle9647]

Ever since your review, I guess Sony paid attention to your concern of unintentionally shifting aperture settings and slightly adjusted the manufacturing process and hence my piece I bought in 2019 has a definite and fairly firm auto (A) position which never caused accidental rotation of the aperture ring. Indeed an aperture lock would have been a likely better solution, however Sony has been obviously pushing the size and weight as low as possible without compromising image quality and autofocus performance.

These examples were very ineffective in determining which lens was best. Image examples were shot landscape...not showing any detail, bokeh, background separation, or night shots....which are some of the main reasons anyone buys a 1.4 lens.

Pro review!!!👍👍👍👍👍

Sigma is 75% heavier than Sony, but Sony is 43% (not 75%) lighter than Sigma. A great comparison, but f/4 on Sigma looks like something went wrong. Are you sure that it didn't blow stronger then? Because it looks like a movement.

[@MatthewGore]

Yes, true about the weight... maybe I was a little sloppy there :-) Re: the f/4 blur, that was my first thought, too... that I touched the tripod, or there was a gust of wind, etc. But I had the same result at f/4 in four different shots at the same location, and also at f/4 at two nearby locations. In each case, I shot two shots each as I went up from 1.4 to f/8 or f/16, and then down to f/1.4 again, re-focusing between each shot, so they were taken minutes apart at least, and much longer than that in some cases. Also, the shutter speed was still around 1/1000th of a second, which is generally beyond the range that vibrations play a significant role, though it's not out of the question.

Matt, I think you have done a fantastic job showcasing the low light capabilities of the new Sony 24mm F.14 GM. I liked the video and subscribed to your channel. Do you think the low light capabilities of the 24mm F.14 GM outweigh the 16-35mm F2.8 GM for outdoor low light video conditions drastically? I do a lot of low light virtual walk tours with the 16-35mm F2.8 GM right now (Using A7iii body + Zhiyun Crane 2 Stabilizer). I usually set the focal length to around 17mm or 18mm to compensate for the Sony 4K video crop and Adobe Premiere software stabilization crop while still providing a true virtual wide angle experience. Despite being absolutely blown away by the 24mm F1.4, I am concerned it is simply not wide enough for my style of videos. I definitely welcome your opinion if you know any better alternative. Anyway I would greatly appreciate if you could check out my recent videos and provide HONEST feedback. Subscribe if you enjoy :)

The F4 Sigma may have the same Problem like on the APS-C lenses 16mm and 30mm, which only have this defocussing problem at one specific F- Stop, with Viewfinder and AF-S. Sounds weird? It is weird. Same F-Stop and Display --> No problem. Same F-Stop, Viewfinder and AF-C. No problem. Any other F-Stop no problem. Just Viewfinder, AF-S and I think it was F2.0 at the 30mm and F2.8 at the 16mm??

@@Offbeat_Universe As a rule, I don't shoot "reviews", mostly because pretty much all modern lenses are so good that if you don't have something to compare them to, they all just look good... which isn't very helpful. Since the EOS R system only has a few lenses, and no 3rd party lenses, it would mean using an R lens compared to an adapted lens... and that starts to get tricky, since adapted lenses tend to have poor AF performance, and there's some slop introduced that can potentially affect image quality. I'm also not much of a fan of the EOS R system yet... so far I prefer the Nikon Z7, though I hear Canon may make an R model with IBIS soon. So, I'm more likely to do Nikon Z than Canon R, but who knows :-)

@@jmanjr Thanks Jon :-) I understand that a lot of people subscribed to my channel during the time that I was reviewing Canon lenses, so it's understandable for them to wonder if I'm still going to be making Canon videos.

54 тыс и 129 тыс рублей конечно сони лучше :)

[@MatthewGore]

Yes; the question was really only whether the Sony was significantly better; better enough to justify the difference in cost. :-)

Thanks a lot! The video is very helpful for me. Dead bodies )))). Everything is like in Russia)))))

Sony wins.

this is a stupid test. why do not you try to test under more harsh sunlight? or i mean harsh condition. All lens will work well on an ideal lighting condition, even an iPhone ! how about distortion? colour reproduction and micro contrast? most of the lens can easily get 30-40mega pixel but they are not the same! those are the reasons that people need to buy GM or CZ. you are just like a Sigma like want to own a cheap lens

Lol that really cool

This problem about the locking of the aperture ring is the dumbest thing I've heard seriously. Do you check your setting after the fact or what's up with that, if you can't find the 2 sec time to check your aperture and setting just before shooting then the problem is really elsewhere imo... not the lens. I mean what the hell do you do with that lens to have the aperture ring move without touching it, this just sounds childish and not professional at all.

I just have to say, your channel is brilliant, I came across it today looking for reviews of the Sony 24 1.4 G master that I have just ordered and your reviews are so in-depth, I love your sharpness tests, corner to corner, just so good, thanks for taking the time, it beats all the other channels I have seen!! followed and subscribed!! www.louisamore.com

Thanks, Louis. I'm glad people are still finding it useful :-) I just checked out your website, incidentally, and your work is wonderful.
