Sigma Adds the 15mm F1.4 DC | Contemporary to the RF Catalog

[Richard-CN]

The Sigma 15mm f/1.4 DC Contemporary is a new large-aperture wide-angle prime lens, specifically designed for APS-C mirrorless cameras. This replaces the Sigma 16mm f/1.4 DC DN. Which, to be honest, I never liked the 16mm F1.4 DC DN, so I'm very curious about how this Sigma 15mm f/1.4 DC Contemporary stacks up to the lineup.

Sounds cool!
I am not into the Sigma primes yet, but I am very pleased with size, built and quality of my 18-50/2.8.
And if they can keep the IQ while reducing size and weight, that'll be always aprechiated.

That was my beef with the 16mm. it was gigantic.

 

[Bob Howland]

I would have expected the 16mm to become a 17mm, to center it between the 12mm and the 23mm. Maybe Sigma is rethinking their whole APS-C prime lineup, emphasizing their use in video. Does the 23mm become a 20mm and a 25mm? I do think they need a 40mm APS-C prime.

After the 17-40 f1.8, was spected they start renewing the 16 and 56 primes.

Can you add an MTF comparison 16 vs. 15 to this article?
A quick look tells me the 15 mm MTFs look even better...

What size is the image circle?

 

[John Wilde]

"no word yet on an L-mount or Nikon Z-mount version of this lens."

(Sarcasm) If Nikon is blocking this third-party lens, everyone should get mad and quit buying Nikon cameras.

What size is the image circle?

Oh, man -- that's a can of worms...

 

[GirlsAreBeautiful]

I wish they'do a 28mm equivalent, but nobody wants that

 

[Planterz]

This is an APS-C lens, there will be no L mount version.

What size is the image circle?

Small. Check Dustin Abbott's review. Used in on a full frame there's tons of space that's blocked, and cropping it away leaves only a slight tad more than the APS-C crop. He's using a Sony though, so a Canon 1.6x crop sensor will crop a slight bit more.

You have a point. Don't you reckon they refresh the 30mm f/1.4 first, since it released 2 years earlier than the 56 f/1.4? I have been eyeing that 56mm prime for a while as a cheap APS-C portrait lens with decent bokeh, but now I am unsure whether to get it or wait for a much improved MkII. My hope is that it releases before June...

added, quite a better when you consider the difference in size between the two lenses. Also added in the size comparison and cleaned up the starting paragraph. not sure where my brain was yesterday.

I know this lens is for APS-C, but if you mounted this on an R5, would the R5 go into APS-C mode automatically with a third party lens and would the AF still work? (I know it works properly with Canon EF-S/RF-S lenses)

apparently it auto switches to APS-C. if you use APS-C lenses without any electronic interconnects though, you'd have to switch the camera to APS_C crop manually.

The 30mm was decent, but it didn't reach the quality level of the Canon 32mm for the EF-M, so there's certainly room for improvement. It was also a very basic design, unlike what we've seen in more modern Sigma lenses. So it wouldn't surprise me if the 30mm is up before the 56mm, which was a stellar lens.

As far as the 56 itself? you really can't go wrong in getting that lens now. I had it for the EF-M mount, and absolutely loved it. A new lens would certainly have better corners, but that's not really as important for a portrait lens. When we were looking at doing some review stuff for CR, and I would be focusing on APS-C it was one of the first lenses I wanted to get again.

Sigma has the 17-40/1.8 so a bit more separation from that makes it more attractive to a wider range of people. Also while 16x1.5=24mm FOV on Sony, to get to 24mm FOV on Canon it, needs to be 15mm.

While the 12mm is still quite new (and is in their new design language) when it is eventually replaced in some years I would expect they'll make it a 10mm lens (or maybe 11mm) to get an even wider angle FOV on both 1.5x and 1.6x APS-C.

I have the 16, 23, 30 and 56mm RF-S lenses. Actually, the only Sigma RF-S lens I didn't yet have was the 12mm. Now the 15mm F1.4.

The refresh of the 16mm is welcome. Like Richard, my main problem with the 16mm was its size. Otherwise I'm quite happy with it. The new 15mm looks very enticing for the size/weight improvement for portability. I might end up getting it.

I really like the 56mm F1.4 and don't feel a need for an update at all, honestly. I'd be more interested in updates to the 23mm and the 30mm. If canon were to release an RF-S 22mm F2, then I'd skip any 23mm update from Sigma .

I own the 16 and use it with an R7 and with an R50V on a tripod. What does the 16 f/1.4 not allow you to do that the 15 f/1.4 will do, ignoring for a moment the added control ring? Mostly I use the 10-18 f/2.8 instead.
