I can imagine the skateboard community will be very happy with this. Fish eye is the go to lens for skateboard films

Kudos to Sigma. This is a fantastic unique lens.

6:40 Have you ever seen the incredible Hubble Deep Field? Thousands of galaxies visible from one tiny patch of the night sky. Simply breathtaking to consider all of that exists in that tiny region of the sky.

Not sure I 100% agree with people saying it's the first native fisheye AF lens for Sony E. It kinda is since it's a single lens but it's also true that the 28mm with adapter has been available for years. That combo (SEL057FEC + SEL28F20) has worked decently for me though I have always wished Sony would come out with their own proper fisheye. I was hoping the Sigma would be smaller and replace the Sony combo when I first heard the news but...alas. For those saying you don't need a fisheye, you are missing the point. They make interesting images and, when you run across a subject that would look cool shot with a fisheye, it's nice to have one in your bag. Some of my favorite shots over the years were made with fisheyes, so I have carried one for every system I have owned (Nikon, Oly/Pany, Sony).

The price isn't too bad. The Canon EF 8-15 is £1300+ (and out of stock) on WEX, the Nikon F 8-15 is £1450. Nothing much native for RF or Z except much cheaper and inferior lenses or manual focus ones. It's the kind of lens, if you need it, you'll know it. Great for 360 panorama work and super wide sky shots amongst other things. It's a wonderful new lens for Sony shooters who otherwise would need to adapt other lenses and the quality looks fantastic for a fisheye. Thanks as always for your excellent reviews.

Happy to see three uploads within the day 🙏

This is one of the most interesting lenses released in the last year and there have been a lot of intersting lenses.

Wow what a lens and build quality. Expensive but you can clearly see why 😍

Oh wow, thats an incredibly performing lens! Sigma outdid themselves here. Great test as always. Fantastic to see those companies trusting you with testing those unreleased products! Let me just add, that nikons 6mm fisheye had a tripod collar too, but I'm not sure if you would want to count that.

The rare "Hi/hey, it's me" is my absolute favorite intro by Chris

This is one impressive lens! Definitely one of the most interesting E-mount lens in the last 2yrs. Can't wait to see what Sigma cooks up next

The price reminds me of when Sigma released the 28mm and 40mm ART lenses. They were niche and crazy expensive for their first few years and then they came down in price (and are the best ART lenses ever made)

8:10 love the music from The Sims!

"This lens does come with one of Sigma's excellent bags, but it is not image stabilized." - What I would do for an image stabilized bag.

Coma is really well controlled here, excellent

Going on a tour to old industrial places in North Rhine-Westphalia in a couple of weeks. This might come in very handy in tight places, when the 12-24 GM is not enough. Thanks for the review! 😊👍

Gorgeous and sharp lens! Shame Canon still has not opened RF for other companies

Wow, that's impressive! Now that Sigma has brought out the new f/1.4 in 14mm and now this 15mm fisheye lens I am seriously thinking of selling my Canon Ra camera and switching over to Sony just for these and the rest of the fantastic 3rd party lenses on offer to Sony. Getting really tired of waiting for Canon to wake up with their dismal lens selection and 3rd party RF choice. It's really tough to keep holding on trying to be loyal to Canon. Fantastic review as always ✨😉 If you are ever up or fancy a trip up to Aberdeenshire/Grampian Mountains then look us up for a meet up 👍😊

Holy fishcakes!!! Was just dreaming of this seeing lens, and you already have a video of it up!!! While flabbergasted, I have to say, thank you for your wonderful reviews!!! 🙏

If this wasn't fisheye then I think this would be a great companion to my Sigma 20MM f/1.4 Art, which you tested and know how excellent that lens is. But if I did need a fisheye then I think this is the way I would go. You can't beat that wide aperture. Thanks for the review!

1:13 Beautiful shot

I love your work Christopher, but have a slight criticism. The corner sharpness test struck me as a bit inaccurate as the focal distance in the center of the frame was very different from the focal distance to the corner of the frame. I would have expected the corner to be out of focus in comparison to the center and stopping down increases the depth of field, bringing it into focus. But it is obviously hard to find a scene to photograph with a uniform focal distance at such a wide angle.

The lack of coma is probably the most impressive thing about this lens, and there are quite a few things like that as it would seem.

I absolutely love what Sigma is doing. They're filling that spot Sony refuses to. We NEED more unique glass on the market. I just may pick this up.

1800 is pretty cheap for a 1.4 fisheye AF lens of this quality. It's a niche lens alright but for specific types of photography/ers it will be a holly grail.

what a funky lens

Thank you.

Between the lack of warping in the corners and very poor close up performance, I wonder if this is a unit focus lens. Not an issue, just would be surprising for such an ambitious lens.

The OG Sony FF e mount 28mm f2 ziess lens had a fisheye and 20mm adapter for it really good and dropped only a stop of light

This looks interesting.

I wish Sigma would go into charity for just one day for me personally. What a cool lens.

Regarding how this lens was born, perhaps a side product of the new 14/1.4 development?

Lens like this would be so nice to get one day, but sadly the price is way too much.

Can use cpl filter for this lens and for sigma 105mm f1.4 ?

Do Sigma provide the correction files to get rectilinear image in post?

while the IQ and overall quality is highly appreciated, it is funny how Sigma is consolidating their lens size recently: while wide lenses build large, they make "small" the long telephoto one (500/5.6) 😅

Bummer, that Sigma seems to have become an E-Mount only brand in recent years. They make some really cool stuff.

2 Reviews at the same time! What a treat ! (or an accident ?)

Such a fun lens! And my goodness - Christopher is certainly among the most lovely hearted fellow on KZfaq. Thanks for sharing that photo showing some of the glory of Gods creation :)

VS Sigma 14mm f1.4?

I love astro photography, this will create new possibilities. I have a Canon camera. Canon is making me sad. Great review

Not to belittle Sigma's achievments I find it strange that it's hard to come by a lens which has some quality compromises in favour of weight advantage, am I wrong? I bought an old Sigma 15mm fisheye recently, it's 2.8 and it's very light, why is there nothing like it today?

Salvadore Dali would love a fishye lens

This 15mm f/1.4 is extraordinary, but who needs a fisheye?

maybe... what's next? f/1.4 circular fisheye?

I hate it when my carry case isn't image stabilized.

If they had a Z mount I’d buy it in a hot second.

impressive...

what!! 15 mm 1.4 😳

6:37 Sorry, that's not what I believe. But we can agree that it's humbling either way.

I don’t get why they release a 15 and a 14mm.

Yes you only live once Mr Bond..

"Just look at the glory of God's creation." Amen brother. I've been looking forward to your review of this lens. Thank you.

Sigma's autofocus is always lacking.

Hi Chris please do review on fuji 8-16 f2.8. i am keep on asking but no reply from you. please we are waiting for that review. Thanks.

Pls retest the image quality with your standard method

What a great Job sigma! Making canon, Fuji, Nican shooters jealous 😂. Sigh…

Too bad they didn't release a Sigma 14mm f1.8 mkII :/

Too expensive

Glory of god's creation? Which god exactly? Must make sure we're not talking about false gods here.

Fish eye lenses are just the most useless lens ! Over $1000 dollars . Buy rectilinear wide angles because they are useful .
