chiumeister: the Sigma 35 1.4 on the Sony A99 full frame will give you image stabilization. Although you cannot use the full 1.4 aperture for video.

In manual mode, you can.

BJL: How about calling this technology "X3", which is the jargon adopted as an industry-standard by CIPA? "Foveon" is just one approach to X3, and not the one that Canon is pursuing, and the "X3" tag is also well-known.

Or, "RS", as in EXMOR-RS? :D

Greynerd: I do love it when sigma bring out a new lens for m43. There is such a massive struggle for so many users with the concept that people would want to buy a cheap lens when they can just get a better lens for lots more money.
No macro. I mean really really mega slow at f2.8, no distance scale, no DOF indicator - it just makes you shudder with the horror of it.

Back in film days, rangefinders often came with a 90mm f/2.8 or f/4 lenses. This lens is technically an APS-C solution for the same effect. That it is available for M43 is merely a case of the option being thrown in.

On APS-C (Sony NEX), this lens, in terms of FoV and DoF, would compare to 45mm f/1.8 lens on M43 which isn't too shabby.

And no point really for distance scale or DOF indicator.

domina: no distance scale? no DoF scale? why? who will use a lens without a distance scale? I'd pay more to have a distance scale. Also, an aperture ring (in addition to electronic aperture control) would be very welcome even at higher price. Also, a lens hood is a must.

Neither is of much use (or accurate enough) in real world, and more so since Sony NEX system allows live DOF.

cprevost: They will sell tons of these. Nothing else like it close to this price range. Hoping it goes down just a bit in price when it actually hits the street. If it's as good optically as the other two they'll have a hit. For many of us 60mm on micro four thirds is a focal length that doesn't get a ton of use so paying hefty prices for one doesn't make sense. Hoping it makes a fine portrait lens.

I love the depth of field and subject isolation I can get on my oly 45mm. How would this lens compare? I know it doesn't open as wide but would the focal length make up the difference?

That is a good point Wally.

ZhanMInG12: No macro ability at this focal range? Making it to 0.5x wouldn't really hurt, right?

I'd rather see a 105mm macro than a 60mm. This is simply a completion of the traditional rangefinder trio, like Contax G (which was 28, 45 and 90mm). If a 90mm lens on film made sense back in the day, the 60mm on APS-C is that lens today.

Diopter: 10mm or 12 mm prime for the E is still deep in the woods.
So a macro in a useful focal lenght .... :-(

The Samyang AF possibility:

When we see inexpensive ultra wide primes, it will be time to raise our expectations. Until then, no. The best bet comes from Samyang, but it might not be a sub-$400 lens if you want quality (and they are pretty good).

That begs the question, which 10mm or 12mm lens do you carry for your street photography, at budget prices?

forpetessake: Hm, not sure what is this lens for. On m4/3, it's equivalent to 120mm/5.6, hard to think of a useful application. On APS-C, it's equivalent to 90mm/4.2 --good FL for portraits, but too slow for that; the existing SEL 50mm/1.8 though slightly short is much better in the other respect. Sigma for some reason releasing lenses, which add little to existing native lenses, how are they going to sell them?

I would say, pretty useless on MFT. On APS-C, not so much. 60mm f/2.8 on APS-C will create a good separation and if this Sigma is like the other two DNs (19mm and 30mm), or Sigma 70mm f/2.8 macro that I have, it will not need to be stopped down. Doing so will allow acceptable sharpness to co-exist with just enough DOF. Even if the lens were an f/2, chances are, most will stop it down to f/2.8.

Sony 10-18 f/4 is pretty good for UW lens. And for a prime, Zeiss is covering it with 12 f/2.8. Samyang is expected to announce its own line of AF lenses for E-mount this year (the decision to do so was put forth last year) and they have 10mm f/2.8 UW too. It won't surprise me if they develop an exclusively E-mount version of that lens as well (as they did for the 8mm fisheye).

smithore2: Where is the weight in the physical specifications?? 1kg???
Why 2.8, it's equivalent of 5.6 in dof on m43, that's too much.

M43 equivalent for this lens will be 45mm f/2.

I suspect the Sigma 60mm to be about 200g.

In reply to:

kimchiflower: It's a shame these Sigma lenses are unnecessarily large on a m43 body as the image circle will cover the larger APS-C sensor of Sony's NEX.

On the plus side, I assume this translates into better corner sharpness for m43 as the corners of the image circle will be further from the edge of the frame.

But they are designed for APS-C sensor, so they have to be necessarily larger. For smaller sensor (MFT), the same FOV and DOF would require a 45mm f/2 design.

Van Boxtel: Will there be a Fuji X mount in future?

Sigma should seriously consider X-mount as Fuji's lenses are priced high and offering low cost solution will be excellent marketing in the brand. OTOH, with Sony, this 60/2.8 will meet 50/1.8 OSS which is only about $50 more, has OSS, and is 1+ stop faster for low light photography, and is an excellent lens.

Stacey_K: I find it comical when a camera system has a slew of amazing zooms, people complain "where are the primes? All I want are prime lenses." So them a camera system comes out with a bunch of nice primes and people bitch "We want zooms" lol

While I won't mind f/2.8 zoom, I think faster primes are a better option, especially at 35mm and 50mm. So, instead of a 16-50/2.8 (which I have and can use on NEX, I would rather carry 20/2.8 (pancake), 35/1.8 (tiny) and 50mm/1.8 (could be smaller) and have a 1+ stop advantage at Focal Lengths where it matters.

DOF on APS-C with 60/2.8 will be practically the same as 45/1.8 on MFT (within an inch at about 8 ft).

tkpenalty: Sigma needs to basically release a full set of lenses for the NEX line... just because Sony isn't.

Well, Sony has:
16/2.8
20/2.8
24/1.8
30/3.5
35/1.8
50/1.8
And an 85mm prime scheduled for launch this year. That would practically cover a FF equivalent 24mm to 135mm.

Then add Zeiss (12/2.8, 32/1.8 and 50/2.8), Sigma (19/2.8, 30/2.8 and 60/2.8) and Samyang lenses (which is also expected to announce AF lenses for E-mount this year).

Zooms: 10-18, 16-50, 18-55, 55-200, 18-200.

peevee1: Olympus, Fuji and Samsung already have slow 60 mm primes, all macro to add. A product manager of Sigma who decided to make the FL for mirrorless should be fired.
All the systems lack cheap f/2.8 and faster ZOOMs though. m43 has a pair, but they are too expensive, others have nothing.

I picked up Sigma 70mm f/2.8 macro for $350. It is an excellent lens, however, for more serious macro, I would rather get 90mm+ focal length.

In that regard, this Sigma 60/2.8 is appealing as a portrait lens. For NEX, it will have to compete with a very good 50mm/1.8, however. The price on the Sigma is great. And if the optical qualities match the 19mm and 30mm lenses, we're looking at perhaps the best trio for value and quality.

As I grow into photography, I'm appreciating primes more. As a novice, I did favor zoom lenses more although they also make more sense to those with limited budget. However, this trio (19, 30 and 60) from Sigma is very impressive, more so for the relatively low price tag on all of them.
