Leaked Photos Appear to Show a Beastly Sigma 18-35mm f/1.8 Lens

Update: Sigma has officially announced the lens!


Could an f/1.8 fixed aperture appear inside an 18-35mm zoom lens? That’s what photographers on the web are now debating after the emergence of a pair of photos that appear to show a not-yet-announced Sigma 18-35mm f/1.8 lens.

Having a f/1.8 aperture on a zoom lens like this is unheard of, and Sigma would be breaking new ground if this lens does in fact materialize.

Officially, the lens is reportedly called the Sigma 18-35mm f/1.8 DC HSM. The photos and specs first appeared on Czech photo site Digiarena before being picked up by Photo Rumors.

Here’s the second photograph of the lens:


This lens would be unlike anything we’ve ever seen before. It’s said to be designed for crop factor APS-C DSLR cameras, and reportedly has 9 aperture blades, ultrasonic autofocus, a 72mm filter size, a minimum aperture of f/16.

Its weight is reportedly 810 grams, and it measures 121mm long. By comparison, Canon’s 24-70mm f/2.8 weighs 953 grams and measures 124mm long. This new lens would be both lighter and smaller than Canon’s lens, even though it opens up more than one full stop wider.

Sigma has been doing quite well with its lens lineup as of late. It’s new 35mm f/1.4 rivals the build and image quality of its big name competitors, yet costs hundreds of dollars less.

The brand has been developing quite a positive reputation for itself, and this new 18-35mm, if real, would do wonders for the company in that regard.

P.S. Does anyone know if it’s some kind of Czech April Fools’ Day today?


    Are those photographs? They always look like SolidWork type images

    For crop sensors? Fail.

  • Steve Stevenson

    Wow that would be great.

    Sigma really upped their game.

    I’ve been messing with their 35mm f1.4, and side by side with the Nikon 35mm f1.4 G, they are indistinguishable.

    Build quality is great on that lens too.

    i’m sure 7D owners won’t complain

    most product “photography” isn’t actually photographs anymore, more often than not it’s a rendering

  • Jamie A MacDonald

    What’s the big deal?
    Olympus has been making a 14-35mm f/2 AND a 35-100mm f/2 for years. Plus they are weather sealed…And not rumors.

    Just sayin’

  • C.K. Lee

    I’m not complaining :D

  • brandon

    they almost don’t even count. they are very expensive, and only work with sissy sized sensors.

  • Philip Han

    Neither am I :]

  • Mansgame

    This Siggy may actually hold its value for a few months before being sold on ebay for half price.

    Totally just had a Pavlov’s dog moment :p”’

  • G

    It’s easier to make an fast lens when it only needs to cover such a small sensor.

  • Peter Metzger

    first: whaaat? This seems stupendous.

    second: why would they compare it in size to the 24-70 instead of the much more comparable 16-35? That seems silly.

  • olafs_osh

    nottt me either!

  • Luc Renambot

    because it would be a lens from crop sensor. so approx. 18*1.5 to 35*1.5

  • Peter Metzger

    aha! I saw people mentioning it in the comments but must have skimmed over that bit of the article.

    ::edit:: still, for a size comparison it seems like they should look at similar-focal-length lenses

  • Oliver

    It is but making it telecentric isn’t.

  • ope

    Its Official !!!!!

    You really don’t know the definition of “Fail”, do you?

  • C.K. Lee

    This just gave me a flashback to The Princess Bride.
