Thanks for having me on your channel Gerald!

I am Gerald Undone and, contrary to the Sony GM, I don't breathe.

I really like how you talk so fast and clean that makes every video like a high quality lecture.

Man i don't own any sigma lenses, sony lenses, or full frame cameras but I still end up watching your videos and learning so much from them because the basic principals and problems when it comes to lenses and cameras in photography and cinematography carry over across brands and models. I appreciate your in-depth reviews.

Thanks for another thorough and technical review Gerald! Considering here in Europe the Sony 1.4 GM retails for €1700, the Sony 1.8 for €700 and the Sigma will be priced at €849 and also considering I will be using the lens mainly for photography and not be close-focusing too often, the Sigma may still be the best option for me.

Hey, I'm Gerald Undone and I put a ND1000 Filter on my Camera and set the ISO to 64000.

I'm Gerald Undone and I put the bottle back in the genie.

my theory with the sigma 35 f 1.4 is that they designed it to be a competitor to the zeiss 35 f1.4. its nearly the exact same size and form with drastically better images. i dont think sigma counted on sony releasing a gmaster just weeks before they released their own. i expect this lens to have a version 2 in the near future.

I'd love to see you get your hands on industry standard cine lenses and compare them against the best offerings from photography companies to see the differences and benefits of each. Just an idea!

Your reviews are as good as Sony’s latest G Master lenses. I appreciate the different viewpoints from the colabs. For me, compact size (and light weight) is everything for street photography and travel, so yet another reason the two Sony 35’s win out for my personal style and use. Thank you for these excellent series of reviews!

How is it that you only have 285k subscribers? just getting into photography and you are my go-to creator as your videos are super in depth. I have bought any lenses because they are expensive but hoping eventually to afford one

A lot of these issues with this lens would be more prominent to photographers and not filmmakers, in my opinion. Watching a movie, I'm not going to "punch in" to look for chromatic aberration or focus bands. I guess that's one of the nicer aspects of filmmaking. Of course, the focus breathing would be an issue. And from what I've seen from this video, the bokeh is pretty clean...except when you "punch in". Thanks for another thorough Undone review. I don't know too many people that cover products with such detail, other than Philip Bloom and Jared Polin. I'm a grateful subscriber to be sure. 😀

That's interesting how different of results we have all seen. I just looked over my head to head results on the a1 between the Sigma and the GM and found that Sigma was equally sharp (a hair better, actually), with the GM having the edge in the outer third of the image circle. I did see the CA you mention in a few shots, but not persistently like you encountered. Did your copy seem properly centered? I've had lenses damaged in transit that underperformed.

Best in-depth review! On my copy of the lens I also did notice a bit of aberrations especially in the catchlight of the model eyes, when using strobe! I’ve been using A7R4, and it was quite sharp, but it was detailed enough to see that aberrations! Cheers from Japan!

Sony f1.8 is still the winner in my book. Had the lens since release and don’t see the need to upgrade 🤙

the "all right, I'm done" had my mind completely undone.

Wow I paniced when i saw all the reviews popping up after purchasing the GM version 3 weeks prior. Glad with my purchase though and reassuring with your review. :)

that hazy diffused look is called spherical aberration. it only shows at close focus distances (~ half a meter or less) and usually goes away by stopping the lens down by one or two stops. my guess is that sigma intentionally left this aberration partially uncorrection in favor of smoother out-of-focus rendering

I watched this to the end too... . Not sure why, really, as my camera is a Z6ii. But, the chromatic aberration demos were interesting. I use DXO and they claim their lens correction modules help a lot. I wonder if they help the Sigma to any significant amount. Assuming there is a module a available... . Well done, again, Undone!

Superb work. I'll very very happily stick with my 1.8 Sony. Booyah xxx

Very perceptive review, thanks for all the details! I do think though that the Sigma is a slam dunk choice over the Sony f/1.8, because it does everything the Sony does plus it offers the option of f/1.4. The f/1.4 is flawed in some situations but in others it shines. Certainly worth the slight increment in price over the Sony f/1.8 unless size and weight are very critical or strong preference.

10,000 views in 4 hours....you've come a long way baby! Ok now I'll watch the video and get undone.

Hahaha I was JUST binge watching your sigma 35’s, g master 35 AND your sigma 40 and suddenly this pops up!

SOOO many 35mm lenses for Sony E and they all have various drawbacks. It's almost funny that this focal length keeps having trouble while they pull off everything else really well like the 14/1.8

Loving the reviews and the guests. Good job guys

Great review Gerald! I can understand your frustration with sigma's productions lately.... The fact is they are doing good yet but the recent sony products are acting like a "game changer" leading the quality in the whole industry! Now comparing this good sigma lens with the Sony GM we can confidently say the GM is the best ever made autofocus 35mm f1.4 in any brands! Yes it's not perfect but is the perfect possible option available!

Good to see the A1 made its way off the shelf!

The Dream Team for lens review. It was entertaining, did not have to press on the play back speed.

I miss your old classic educational geeky videos of Photography and Videography basics. I know why you are doing more product videos. Thanks to your well explanation, buyers can make the right decisions, also, Product reviews give views, it pays well. It is not a critic. Someone has to pay for the hard works. Right? And man needs to pay bills. Because, wedding photography is currently dead, event photography is in the same way, may be, we could use your help to refresh our memory of Basics in Photography and Videography. Because, lot of us (not all) currently can not afford anymore new gears and selling our businesses. Ps, hope this comment is not taken negatively.

It is the Q2 35mm lens :-) I wonder if Tamron will release a Q3 35mm lens. Thinking of it Zeiss too are lagging behind on new 35mm lenses. Sony offers 4 of them while Sigma and Samyang each have 3 models. Tamron and Zeiss drag their feet with only one 35mm lens per brand

Love the close-up wide open tests. I shoot like this as well. Have found that the Sony 35mm 1.8 makes most lenses look very soft in comparison when used this way. It's the first lens I ever used on mirrorless and never realized how spoiled I was until I tried lots of others and found that they can't even compare when used this way. Every Fuji lens I've tried is soft close and wide open; I assume they don't optimize for it.

It's hard to describe, how much I appreciate your work, no bs just straight to the point! Thank you Gerald!

It's a great day when you upload ❤

You should review the Sigma 35mm 1.2

great review, but would have been a bit better if you showed us more outdoor images. I feel like most of the tests and comparisons were taken at very close focusing distances, which not everyone uses realistically all the time

I'm Gerald Undone and today I feel dizzy because my eyes have terrible rolling shutter.

Phew. I just finally received my Sony 35GM the day the Sigma 35 leaked and was shook. Thankfully the Sigma disappoints a bit. Which, however, is pretty unfortunate. Always great to have competition and options for everyone! Great work, as always, Gerald!

Hey Gerald, could you do a round up of cheaper Chinese manual focus lenses for video use? They look pretty decent. For eg: 7artisans, meike, kamlan, ttartisan etc

The only question I need answered is, is it worth the upgrade over the original sigma 35mm 1.4? I'm pretty sure many have those same concerns cause my sigma 35 1.4 getting nervous 😬

I just watched Dustin Abbots video and it's like he's reviewing a completely different lens. Do you think your poor results might be down to sample variation?

I was thinking about getting this lens. Thanks so much for the review, Gerald. It helps me a lot to make my final decision.

Ugh, I really want a 35mm for L mount and I was hoping this would be the ticket. I don't want the sigma contemporary and the 1.2 Art is massive and expensive. I wish Panasonic would release the rest of their 1.8 primes so I could see if the 35mm was sufficient for my needs. Anyway, fantastic review and definitely helped me save some money lol.

This is strange, dustin abbott says at F1.4 it's incredibly sharp! I wonder if there is differences between copies, another great review 📷🙏

I recently bought the Sigma 50mm f/1.4 'Art' and I was confused b/w the 50mm, 85m, and 35mm. When comparing them with Zeiss Batis and Sony Lenses, the price makes a huge impact because of that 1.4 aperture. Also! It's built like a tank as compared to cheaper Samyang/Rokinon offerings. I tried my hands on both G-Master and Zeiss, if the price wasn't an issue, Zeiss Batis all the way. While as far as G-Master goes, both 35mm and 50mm but not the 85mm, I would rather take either the 1.8 version or the Sigma.

That's interesting. That hazy look is exactly like a problem I have with an older A-mount Sigma 70-200 2.8 I ended up getting rid of. Never been able to figure out what the problem was exactly.

So glad I watched this video, as I originally planned on getting this Sigma, but was unaware of these problems he mentioned. I went back and watched his video on the best 35mm for Sony. In the beginning he mentioned why he didn't include the Samyang 35mm 1.4 I hope he looks into the version II of that lens! Apparently fixed some of those issues? Could be the best 35mm for the money?

Hey Gerald, love your lens reviews, but could you please start testing vignetting? I imagine Sigma's larger lenses may have quite a bit less vignetting than Sony's, especially wide open, which is quite important for low light shots where we're already cranking ISOs for the center.

So crazy. I recently got the 35mm 1.2, because it out performed the Zeiss 35mm 1.4. Now there are like 5 more 35mm focal length options. How long can Canon and Nikon continue to prevent Sigma and Tamron from making lenses? There is little enough reason to buy a Nikon already, but since neither of them can ship the few lenses they make, Sony is just that much more attractive to the remaining dslr shooters looking to jump.

Great review, Gerald. Loved the final Gordon kick😉. Anyway, I am Gerald Undone and I put the Pi before Sigma.😜👍

Love that you don't put brand preference ahead of objectivity. That specular blooming and lack of contrast is a bit reminiscent of some of the super fast manual primes on the market, my M43 & E-Mount Mitakon's show this quite distinctly at f/0.95, my Voigtlander less so (still not what you'd call a sharp lens. 35mm is one of my favourite focal lengths too, though for Sony FE my favourite overall to date is the Samyang Tiny Prime. I recently lost mine for a few days as I had inadvertently put it away on my M43 lens shelf. It is just that small. Sigma are one of my favourite lens manufacturers too, so a bit of a shame they didn't completely nail this. I recently picked up the new Sony FE version of their 85mm f/1.4 and that thing is ridiculously good.

Sigma 35mm f2 has the same strange fuzzy haziness in close-up shots and it drives me mad. In normal distances it's an exellent lens.

I’m Gerald Undone and chiggi chiggi bonga bonga

Even if it's 2x cheaper than the Sigma 35mm f1.2, it would have been nice to see a comparaison between the members in the family!

sigma 35mm 1.4 dg dn or sony 35mm 1.8 ?

What about the sigma 35mm 1.2. I think if you are not tight in the budget and your biceps，go for the sigma 1.2😂

I enjoy the cross-over videos, very fun!

I'm Gerald Undone and the mysterious camera is the friends we made along the way

Thank you so much! Getting up close to wildflowers is super important for me and you saved me from an expensive mistake!

Any update on this with production models?

Not even mad that I spent $$$ on the GM. I thought I’d regret it, when the sigma came out, but nah. Thanks Gerald!!

Killer review, in more ways than one. Gotta love Gordon ^^

I can't hear any construction noise, and I am listening to my Bluetooth speaker. All good. Nice rev Gerald!

Great Review. Nice you consider unconscious bias in your reviews too, not many youtubers do that I think.

Hey Gerald! what kind of camera was Jarod using... also an a7sIII or ??

Always breaking it down as always. Love your videos 📹 man

I hope Sony does a new 1.8 version where they house it in their new G/GM style with the aperture ring, hold button, and the 67mm thread size. They basically don't have to change anything else about that lens, just rehouse it and I'm a buyer.

If you want to focus close on a 35mm, get the Tamron, super sharp and 6” close focus. A 1:2 Macro.

thanks for the review Gerald. I''ll stay with the Sony 1.8

Thanks Gerald for such detailed comparison review, i am comparing Sony 35gm and Sony 35 1.8 If I am a video maker and don’t really mind focus breathing issue. Wondering the video images quality gonna make any noticeable difference on FX3 ‘s 4K 10bit ? Consider the resolution is very low on 4K. My key consideration is image quality on video.

Thanks for a very comprehensive and clear review! Seeing this trend with more and more lenses these days .. close focussing compromised to get closer to GM infinity performance (and size/weight) at a lower price point. I guess it makes sense looking at typical usage, but I really like to shoot 24 & 35 focal lengths up quite close. Other case being the new Samyang 24/1.8 close focus compared to GM24 .. However that one did less worse compared the GM at an even lower size & price. Not sure what went wrong with the Sigma. Oh well .. luxury of choice is a good thing. Edit: Kinda loving the slightly outlined bokeh from the Sigma. Very nice aesthetic!

I just bought the old Sigma 35mm F1.4 Art DG HSM for Sony E. I wonder how it compares?

Wow those details at 12:28!! Insane!

Awesome video as usual. Love the second opinion sections you have been doing lately.

Hi, Gerald! A bit confused I couldn't find your review of Sigma USB DOCK for lens calibration. Is it much of a value for a Sigma lens owner? Pretty sure lots of subscribers would be happy to get it UNDONE!

Do you have a review for sigma 85mm 1.4 DG DN?

I'm glad to hear all of this about the sigma. I just got my G Master, and WOW worth every penny. Great video Gerald!

You are amazing, I was just about to buy this lens, I hope their 50mm for Sony E mount is better. Manny loves this lens, the 35mm that you are reviewing, but it was how he was using it.

This is how my rf 35mm macro felt.. never fully in focus

I stay with the Sigma 35mm f1.2 I love that lens

So you’re saying the Sony is optically way better for the money ? Also most people don’t use a 35 1.4 for macro .

Bought the GM, just because of this review after selling the DG HSM.

Great crossover!

Hopefully, this brings the DG DN 30mm price down further :). Seems like quite a few people may be trading theirs in for one of these. Hand me downs are me.

I notice that you haven't reviewed the Zeiss Batis 40mm ... I would be interested in the Gerald Undone treatment and how it compares to your favourite 35 mm 1.8 lens from Sony...

You couldn't have said it better. I am on the hunt for a new 35mm and am so torn! Sigma 1.4, sigma 1.2, sony 1.4GM (pricey) or the old sony 1.8... too many choices!

Orange and Teal in lens... Sick

Thanks for this video. I had the sigma 35 on order and cancelled it to go with the GM instead!

Next intro I'm Gerald Undone and that's how the cookie crumbles

I'm Gerald Undone and my bokeh balls bring the boys to the yard.

I too love the 35mm focal length. I have to say, the best I've ever used is the Tamron 35mm f/1.4. Granted it was made for DSLRs, but even adapted to mirrorless, I find it's sharper right to the corners than native equivalents. Probably not your best choice for your system and what you do. With all the great improvement in optics in the last few years, it's great to have such an amazing option for my D850.

Hi Gerald. Great as always, thanks! I own the older 35mm f1.4 Sigma art e-mount. I use it on the fx6 and fx9, so video work it is mostly used for. I guess the upgrade isn´tHow'sadvance, cheers, Matthias

Fantastic review Sir Love it 💯

I'm Gerald Undone, and I'm not crazy.

I got my 35mm GM last week and it rocks!

Hi Gerald Do you recommend to upgrade from the older sigma 1.4 version to this brand new?

Thank Gerald ! 35mm is perfect for full-frame, but I used APSC might be get some else lens, could you advise best lens for eos 90d for my youtube works.

I’m Gerald Undone, and I find that grabbing a lens by its glas increases my grip, which is good

so basicly you stop it down to 2.8 to match performance of sigma 24-70 2.8 ...so what is the reason of buying prime lens than ?

Your best lens review to date.

I feel like this Sigma shows how good the Samyang f1.4 AF is
