Sigma 17mm f/4 DG DN 'C' lens review 

The build quality of those I-series is gorgeous.

I would love to see a comparison with the samyang 18mm

Another win for the Sigma I-series! These lenses are just awesome.

I thought this could be perfectly suitable for Sony ZV-E1

A moment of silence for rf users like me with no 3rd party lens support

Bro choose to upload 3 videos at once. Thanks, Chris.

I love this lineup, but very disappointed they made this one an F4. And yet they kept the price just as the others in the i series. This sucks because I have been waiting for them to make a 17mm f2.

Is this really worth it over the Samyang 18mm given that its the same size, F2.8 and half the price. what do you think ?

Actually, I am planning to get this for an aps-c TL2! The beauty, size/weight, close focus and distinctly wide 25.5mm make for a nice casual kit.

I'd rather choose Tamron 17-28 f2.8, you get better aperture, a zoom lens, with the drawback of a bigger and heavier body. If you choose a nice second-hand one, it would probably be cheaper than this Sigma lens. Is anyone with me?

Much rather get the pz 16-35 f/4 or Samyang 18 2.8.

Great review - I would love to see a video where you go through the making of your reviews!

£500 for a 17mm f/4 pffft

I own one of this lens which came with the Lumix S5 when I bought it secondhand. Originally I intended to sell it to get a 35mm 1.4 DG DN instead for videography, then all of a sudden I started using it and man. I changed my mind on selling it. Even though it is not the fastest lens out there, the minimum focus distence is very tempting when it comes to versatile lens. I am very happy with it.

thank you very much for the illustrative review .. Whereas I doubt to have any issues with the parallelly released nifty-fifty, here my impressions and minus points about the 17 mm (translated on the go .. by< google, pardon for any imprecise wordings therefore...): A short focal length, packed relatively compactly, is a good idea. Although the image quality is very good, except for the strong distortion in RAW (which costs image quality when corrected!), I have two points of criticism - the lens is actually much "too small" - measured against the 20 mm 2.0, its size would have been okay and would have fitted in very well with the series, at least with a speed of 2.8 - Measured by the mechanical aspects and the low "speed", I find the price too high, actually it should be at least 100 € cheaper I don't understand why Sigma (like many or actually all photo manufacturers unfortunately) doesn't ask the users beforehand about their wishes. In any case, I would have said that I find so much compactness for so little speed problematic. A bit bigger, but F 3.5 or 2.8 would have been great! I now use it as a second lens next to, for example, the Canon TS - E 17 mm shift lens - at least the focal length and perspective match So, dear company Sigma: set up a customer advisory board, then everything will be better

Still a bit expensive for a rather limited use focal length with limited aperture and high correction needed for vignetting. Hmm I think 20mm f2 is probably worth saving up for.

I might opt for the Sigma 20 2.0 instead if the extra 3mm wider is not needed...

"This would be lovely on my EOS R5." Which is why Canon bans third-party lenses.

why cant the DC DN line be as sexy as the DG version :(((

Thanks for the review and for keeping reminding Canon what their customers wish :)

Did you perform the distortion and vignetting test on APS-C?

Man, that lens seems great optically, wish it was brigther, I have the Samyang 18mm f2.8 which is neat good little lens, and beside if anyone seriously need the aperture ring and the build quality I can't see who will choose that lens over the Samyang.

The lens I’ve been waiting for. Chris is definitely a premier reviewer, first of the lot to review this.

Can't think of anything attractive with this lens... size:aperture ratio, focal length... it's totally boring.

who’s asking for these focal lengths & apertures ??? i’m curious sigma is getting crazy 😂

I hate to say it, but I think we have to start to come to terms with the idea that $600 is just about as inexpensive as lenses are going to be from established third party companies now. For a lens much less than $600, I think we'll be looking at Samyang's budget line. I could be wrong, but major corporations seem to be fully embracing this moment as their time to permanently raise prices and blame "inflation" (despite them all showing record profits...".

What is the weight, do you know? Sigma says 225grams on it's site, but resellers over in The Netherlands say 350 grams.

Thanks for the - as always - great review. I have a little bit off topic question: Are you going to review the new Samyang 35-150mm 2-2.8? That would be really great! I´m asking myself why there are hardly any reviews out on this quite exciting lens? I only found 4 reviews in total so far, the biggest channel having 24k subscribers, another english channel with 1150 (!) subscribers, a polish channel with 12k and an italian channel with as little as 326 (!) subscribers. I wonder why so few and so small channels seem to get review copies, while there is not a single review out from the bigger review channels like yours? Just to clarify: I´m not suposing any kind of conspiracy nore am I complaining and even less blaming anyone. I´m really thankful for your great reviews and just can´t wait to see your review on this lens. 😊

I really want this kind of lens

A small point of order: Sigma lenses marked with 'C' are the contemporary line. Art lenses are marked with 'A' and sport lenses with 'S'.

Waiting for Chris to review the new Nikon Z 85mm f1.2.

I may have to ad Panasonic mirroless in order to have this lenses Canon user no wonder what is their problem !!!

If it was F2.8, it would be better for vlogging. 🤍

I have a couple of this style lenses. Thanks for your recommendations.

when looking for lens review, i always go here, Great channel!!

LOVELY!!!! Thanks for your info!!!!! 🙏🙏

A perfect match for the new Sony ZV-E1

Funny, my conclusion was that Canon users are lucky they can get an RF 16mm f/2.8 for $300. It’s obviously not the same performance level as this lens, but it works extremely well - especially for video.

Canon, dump this stigma, get with Sigma. And Tamron, and Viltrox, and yadda yadda.

too expensive for the aperture

I would still pick up now getting very old voigtlander 15mm f4.5 III instead this one, especially for the price.

Pls compare it side by side with Samyang 18 2.8 🙂

I’ll stick with the Canon 16 f/2.8. Looks like a good option for Sony and L-mount shooters, though.

Worth pointing out that this is NOT a weather sealed lens. The lens mount has a rubber gasket and that's as far as the weather sealing goes.

The Samyang 18mm f/2.8 looks the better buy if you don't mind the worse build, from Chris' review it is much sharper in the corners at shared apertures.

The price is too high for this being an f/4. It is a gorgeous lens and the IQ looks wonderful, but it is overpriced for my taste.

Would prefer them to release an 18.5mm F2 for Sony APS-C which would equate to about 28mm in full frame terms...Also F4 is weird starting place. Sigma is creating alot of "unique" lenses lately but we still don't have the essential primes yet

This lens looks nice, but I keep on being happy with the RF 16mm 2.8.

I'm surprised Sigma didn't go with 10 straight aperture blades for excellent sunstars. It's not like you're going to be needing round bokeh highlights with a 17mm f4

The Samyang 18mm looks a lot better in the corners than this lens.

600$….overpriced

I do not understand "I Series" for what is?

Third party lenses have literally n ever functioned on Canon cameras correctly because of their anti-competitive behavior. How incredibly dumb does someone have to be to still be using Canon cameras after the last 20 years of their crap?

Sweet!

Maaan.... Canon RF 16 2.8 is lighter, brighter, smaller, and two times cheaper. Who would buy this Sigma over Canon

Lol Sigma thinks they are Leica with those prices.

As usual, you have a short memory Chris (perhaps not surprising when you have tested so many lenses)...This new Sigma 17mm f4 is actually a totally pointless lens, and Sigma have completely wasted their time and money on creating it because your also highly recommended Samyang AF 18mm f2.8 FE is just as sharp and contrasty as the Sigma when stopped down to f4, it has less distortion, it's a noticeable 75g lighter, and it's almost half the price! The only pros Sigma has are slightly better flare resistance and it can focus to half the distance the Samyang can, but the Sigma does need to be stopped down f5.6 to get the same close up image quality the Samyang has at f4, so it's not really much of an advantage.
