Sigma May Be Building a Groundbreaking 24-70mm f/2 Lens for Full Frame Cameras


Sigma has been on a tear as of late. Since late 2012, the company has put out a highly regarded 35mm f/1.4 lens, a novel USB dock that lets you calibrate lenses at home, and a revolutionary 18-35mm lens with a constant f/1.8 aperture (shown above).

It appears Sigma is only just getting warmed up: new rumors suggest that Sigma may be building a 24-70mm zoom lens for full frame cameras that boasts a constant f/2.0 aperture.

Canon Rumors is hearing from a new source that Sigma is developing a 24-70mm f/2.0 OS HSM lens for full frame cameras (the 18-35mm f/1.8 was designed for crop sensors). This would be huge news; do a search for “24-70mm” on any online gear store and you’ll see that the largest fixed aperture currently available for this range is currently f/2.8.

This new Sigma lens — if it indeed exists — would offer an additional stop of light over its highly acclaimed (and pricey) competitors.

The Olympus Olympus 35-100mm f/2.0 ED is another zoom lens with a constant f/2 aperture

The Olympus Olympus 35-100mm f/2.0 ED is another zoom lens with a constant f/2 aperture, but it’s made for smaller 4/3 sensors

What would be even more amazing would be if Sigma manages to keep the lens (relatively) small, light, and affordable. The Olympus 35-100mm f/2.0 for 4/3 sensor cameras costs $2,499, is over 8 inches long, and weighs nearly 3.3 pounds.

According to the rumor mill, the price tag may be as crazy as the f/2.0 aperture. CR says it would “definitely come in under the Canon EF 24-70mm f/2.8L II,” which currently costs $2,299.

Sigma's new lens will likely compete against (and be cheaper than) the Canon 24-70mm f/2.8 II

As for availability and announcement date, the Sigma 24-70mm f/2 may not be very far off: Sigma is said to be preparing to announce the lens at Photokina in September 2014. Stay tuned — this could be a big one!

    My pants are tight….

  • Jacqui Dee

    It great to see a Sigma pushing lens technology like this! I’ve been very impressed with the new Art series lenses so far.

  • Killroyâ„¢

    Shut up and take my money!!!!

  • Syuaip

    Please be sharp wide open. Amen.

  • David Portass

    If this is true then FOR THE LOVE OF GOD PUT SOME WEATHER SEALING ON IT or at least just a gasket on the mount!!!

  • Trythe1

    Time to put up the old 24-70 for sale

  • faloc

    Im still keeping my first version 24-70 2.8L it has never let me down! Also it just went through renovation at canon

  • faloc

    well lets just hope their AF is better…. it used to be horrible! Though they should add a rubber gasket for weather protection… that’s always missing from sigma

  • Sarah BK

    Would be awesome if the price was too! That focal range is still awesome for a crop sensor dSLR… at least for me.

  • waterengineer

    Build it and we will come. I will be close to first in line if this lens actually materializes in Nikon mount. To be able to isolate at f/2…….sweet.

  • waterengineer

    Totally agree.

  • IU

    With OS!

  • markz

    Still keeping my 28-75 2.8L.

    fallen off an elephant (“only” a small Thai elephant though) about 13 years ago

    been hit by a car in 2006

    been drowned (and I mean drowned) in monsoon rain many times

    just had it serviced and the focus motor replaced (had to track down NoS parts on eBay) as it was actually in pieces but still working, probably from being hit by the car 8 years ago.

    Still works, still helps me get great images, can’t see need to “upgrade”
    though I do admit sometimes the range is awkward on a crop sensor camera.

  • Colin Peddle

    Honestly…. have I said my pants are tight yet?

  • Peter

    I agree having OS would knee cap the Nikon and Canon equivalents.

  • Alan Klughammer

    sigma have generally been very good optics with ok build quality. This could become a must have lens if the price is right.

  • Scott M.

    Wouldn’t it be huge? Like the super chub, 200mm Nikkor 2.0?

  • Brian C

    My body is ready.

  • alex micu

    actually this is the way of sigma to make sharp f/2.8 lens :D

  • JoeNoName

    Lately the Sigma has proven to be top quality, even Zeiss or better in some areas and at a relatively low price. The 18-35 f/1.8 is amazing wide open, the 35mm was beautiful, if indeed this rumor turns out to be right I would expect a great piece of glass worked.

  • Mike

    I don’t see what the big problem is, just use a condom.

  • Mike

    Mine are somewhat wet

  • Melka


    Now if you could bring that 18-35 for Nikon, that would be great.

  • Seb

    Hopefully they finally ditched their horrible camera bodies and invest the spare money into lens development. Otherwise im looking forward to that lens, but lets wait for the price tag :)

  • bmassao

    I had a 28-75 2.8L. It was robbed with my Canon A2E back in 2007. I miss this piece of glass a lot. :(

  • Stan

    This. I owned a Sigma 24mm 1.8 lens and it was a jack of all trades (macro, wide aperture, wide angle) but the autofocus was horrible, the focus ring, too. The edges were horribly soft even when stopped down. This prime had worse picture quality than my compact zoom camera or the Canon kit lens. I sold it within 6 months and bought a Canon 85mm 1.8. A whole different ball game.

  • Scott

    I’m eventually going to want a 24-70, if this thing is as well regarded as their other offerings lately then it will be right up my alley. Better subject isolation and low light performance? Yes please.

    And yes a stop does matter to some of us who shoot on the edges of current ISO possibilities ;)

  • Valentina

    who wants subject isolation? i want unlimited dof.

  • Scott

    Crazy town LOL

    I shoot sports and music. :D This lens doesn’t at all sound any good for yourself then. What do you shoot primarily?

  • Mike

    Is 2014 a typo?

  • powerslave12r

    I hope they dump money from lens profits into developing their camera bodies around the awesome Foveon sensors.

    Sigma is already disrupting the dinosaur lens industry.

    About time they got started with camera bodies as well.

  • Judith

    Who wants subject isolation? Editors – and it also allows maximum possible shutter speeds for sports etc. Ever see a life-size print in which every hair is in razor-sharp focus – but the next person is blurred?

  • TPB

    I hope so

  • Kurnia Lim

    I just get the new sigma 35mm 1.4, if this is true then this will be my next lens

  • Andy

    I’m having trouble believing that such a lens is even possible. Look at the 18-35mm 1.8 lens – it has smaller range than other aps-c zooms and no OS.

  • foukographer

    Well, that could be said of the past but recent Sigma offerings definitely show that the company is into a whole different range now.
    Their 35 F1.4 is a real jewel.
    I expect no less from their future products.

  • Gerhard Korts

    Indeed, to compare a 24 and a 85 is the same like comparing tennis and golf

  • E-Nonymouse A

    I am definitely moving away from zooms in terms of lense preferences but a good lense in this range would not hurt my feelings at all if ended up in my collection. It’s the range of focal lengths I use the most.
    Totally agree with the weather sealing, if it isn’t there it should be. I also hope they are tightening quality control a lot more, I still see a fair number of complaints from Art lense owners who have bad copies or poorly calibrated lenses that AF correction couldn’t fix. I hope my 35mm 1.4 that arrives today will not be one of those.
