Sigma’s New 35mm f/1.4 Costs $899 and Can Connect to a Computer via USB

Sigma has officially launched its new 35mm f/1.4 DG HSM lens for Canon-, Nikon-, Sony-, Pentax-, and Sigma-mount cameras. The Japanese-made lens features a sleek matte finish, low dispersion elements, multi-layer flare-reducing coating, a hyper-sonic motor for speedy and quiet AF, and a 9-blade diaphragm for smooth bokeh.

Priced at $899, it’s much more affordable than lenses with the same focal length and aperture offered by heavyweight camera companies. By comparison, Canon’s offering costs over $1,300, Nikon’s is over $1,600, and Sony’s is over $1,400.

What’s really interesting about the new Sigma 35mm f/1.4 is the new USB dock (sold separately) that will allow you to connect your lens to a computer:

Using a special program called SIGMA Optimization Pro, photographers can make adjustments and updates to their lenses themselves — things like upgrading the lens’ firmware, tweaking the focus to ensure that it’s tack-sharp, adjusting various parameters to suit their personal needs.

Some DSLRs already offer a micro-focus adjustment feature in the cameras themselves, but being able to tweak the focus on individual lenses is something that should be well received by photographers.

Sigma tells us that this lens is the first of its kind to offer this type of USB connectivity. All future lenses released under the new Global Vision line will have this feature.

    contrast and sharpness seem to be better then the canon EF 35mm f1.4 L.
    judging from the MTF chart.

    sigmas MTF chart shows performance @ f1.4.

    can´t wait to test this lens.

  • Ross Jukes

    Oh dear… I promised myself a new lens for Christmas, I wanted a 50mm Prime (but using a 650d with a cmos sensor I’ve been told to go for a 30mm) and wanted a fast focusing, f1.4 lens and was looking closely at Canon’s/Sigma’s offerings… Now this comes out and I’m completely confused!! Should I wait and see what this is like??

  • Dave White

    In other sources it says it will be compatible with both FF and APS-C bodies. Does this mean yes it will technically work but enjoy the crop?

  • ThePope2012

    well… which canon/nikon FF lens will not work on canon/nikon APS-C cameras?

    this is a FF lens and yes.. it will work on APS-C too.. for the people who don´t know much this (redundant) info is needed.

  • SpaceMan

    All of that is nice, especially connecting to computer for tweaks given Sigma’s quality control but can it beat the king – Samyang 35mm f/1.4 – for ultimate sharpness even at f/1.4?

  • Keith

    This is obviously a FF lens, 35mm is a medium wide-angle with an angle of view of 63 degrees. However, when fitted to an APS-C crop sensor, it turns into the equivalent of a 50mm lens with an angle of view of 47 degrees (it is actually 52mm equivalent but the difference in angle of view is very slight)

  • Ross Jukes

    I’ve been looking again and will hold out and see how the reviews go, the price is right at the upper end of my budget but if nothing else it looks amazing!

  • Jonathan Maniago


    I’ve heard that quality control tends to be a bit lax for 3rd party lenses with front focusing/back focusing issues and whatnot. If users could easily rectify these issues with a simple firmware calibration/update, then people wouldn’t worry as much about receiving defective copies. 3rd party lenses would become an even more viable alternative.

  • AW

    The USB idea is very innovative, it might well be worth waiting to see what this lens is like. But I don’t know why you are going with 30mm just because you’ve been told to. You should get the prime lens length that best matches your style. I have a 500D and a 50mm and the 35mm f/2 lens, and a 28mm manual lens, but after using them I think that on a crop camera the 28-35mm range is not really that useful. It’s not wide enough to be wide, and it’s not long enough to get much bokeh. People’s faces often show just a touch of distortion. I don’t know what other lenses you have, but I would do more testing about focal length before you decide. Use you current zoom lens at 30mm or 50mm and see which you like better, borrow lenses from a friend etc. If I had to choose just one prime lens for a crop camera, then I would choose a 50mm every time, it is more versatile. It can handle indoors and outdoors, take nice portraits and get nice bokeh. I can’t recommend Canon’s cheap 50mm 1.8 though, the autofocus is just too unreliable. Very good photos when it does focus right though.

  • Sam Agnew

    So Sigma want to give me the option — as an extra purchase and procedure — to do the quality control that they are supposed to do before selling me the lens? And people are excited by this?

  • David Portass

    maybe not as sharp but there are times when manual focusing all the time is not practical, such as weddings where a lens like this would be amazing

  • David Portass

    yes it will work on both, putting it on an aps-c body will give it (and i know some people hate the use of this next bit but I find it the best way to describe it) an equivalent of a 52.5mm f1.4

  • David Portass

    while it should be the case unfortunately even canon and nikon lenses are not always fully accurate, that can be down to their QC or just the bodies themselves which is why higher end bodies now have AF fine tune to help with this issue. Considering the lens is exactly the same for all bodies just with a different mount and processor they are usually spot on accurate. People should always try the lens they are buying in shop or as soon as it is shipped to them and send it back for another copy should it not be sharp

    This little device will be cool as it lets photographers change the focus speed and focus limit range on some lenses so it’s not just about the AF accuracy.

  • Alexander Petricca

    Great idea with the USB dock but does the cost of implementing it really benefit the user a sufficient amount to justify it’s inclusion?

    As for the lens itself, looks fantastic, I just hope it “feels” right and the image quality / build quality is as good as the aesthetics.

  • Mike Ermilio

    it’s not just about quality control out of the box. Even the best glass can go out of calibration over time. Being able to buy a device that allows me to recalibrate my lenses as I need to would save me the trouble and cost of mailing them back to the manufacturer.

  • Ross Jukes

    Thanks for the advice AW, I only have a standard kit lens (18-55mm) and really shoot a bit of street/landscape and will be looking to do more automotive/landscape work in the future.

    I tend to shoot somewhere between 18-35mm anyway from what I can tell but will look to add a 100mm+ lens at some point, but whilst I’m enjoying street/closer work, I am more in the market for something in the 28-50 range.

    The Bokeh is also quite important as I tend to try to get depth of field into most of my shots. The focusing speed and noise are all things that concern me as well with all of the lens that I have looked at…

    I will wait and see how this lens goes, this is a major investment to me so I will not rush into it, but again, thanks for your advice…

  • Jeff

    Agree. I had to get my Sigma 30mm 1.4 calibrated through the mail last month. All this does is put the “convenience” of quality control into the users’ hands and lets Sigma off the hook. Helps their efficiency and profit margins while doubling the price from my cropped-sensor glass.

  • e-jump

    This usb/fw update capability is a welcoming for Sony users, esp when theres examples of older Sigma HSM lens may not work properly on the SLTs. With this, if Sony made some changes to their future Alpha lineup, a fw update via usb just solves the hassle of seningd the lens back to Sigma for updates.
    And self calibration is welcoming

  • Dario Toledo

    Amazing… I shall see whether it is that good of a performer. Pity its size.

    Anyway, actually you can already fine tune F/B focus on single lenses, at least on Pentax semi-pro DSLRs. They support up to 20 different lenses.

  • Dave Stotzem

    there they go, the stupid “makes it a XXmm lens because for the crop. remarks” That is simply not true. 35mm is 35mm, no matter what crop factor, no matter what sensor. Crop factor affects the image size, and not the focal length.
