Sigma E-Mount 30mm f/2.8 EX DN Lens – Now avalilable for Pre-Order and Sample Pics, And Other News!!

Sigma E-Mount 30mm f/2.8 EX DN Lens

The Sigma E-Mount 30mm f/2.8 EX DN Lens  is a prime lens designed specifically for mirrorless interchangeable lens cameras. This 30mm lens is equivalent to a 45mm lens in 35mm format and provides a 50.7° angle of view. A very nice fixed focal length to work with on a crop factor sensor I might add 😉

Featuring a newly developed linear AF motor, the Sigma 30mm is ideal for use with video and still photography. The linear motor helps to guide the lens elements directly without the need for gears or other noisy mechanical parts, providing quiet and accurate focusing. It’s not as quite as the Sony lenses I’ve heard though.

An aspherical lens design across 2 glass elements provides correction for distortion, field curvature, and color aberration while Sigma’s super multi-layer coating helps to reduce ghosting and flare. With a minimum focusing distance of 11.81″ (30cm), there is room for selective focus and creative depth of field applications, featuring an attractive bokeh due to the rounded 7 blade diaphragm. Sharp and high contrast results are available throughout the aperture range, even with the wide f/2.8 opening.

Weighing in at a mild 4.76 oz (135 g) it’s pretty light and the filter thread is a bit smaller than most other Nex E-Mount lenses at 46mm as apposed to 49mm.

Features Worth Noting:

  • Standard focal length lens, designed specifically for mirrorless cameras.
  • Aspherical lens design provides correction for image distortion, field curvature, and color aberration.
  • Multi-layer coating reduces ghosting and flare and provides greater contrast and color fidelity.
  • Rounded 7-blade diaphragm produces an attractive quality to out-of-focus areas in your photos.
  • Equally sharp results are available from minimum to maximum aperture.
  • Linear AF motor directly guides lens elements for quick, quiet auto focusing
  • Very Affordable at ~$200 US

Sample Photos:

Courtesy of, I found a link to some excellent sample photos by German Photographer Marco Schwinning. Here is the link to the Google Translate page (Click Here), and here is the link to the original page if you can read German or just want to look quick. (Click Here)

The sample pics look very sharp to me and although taken in jpeg mode it’s very good news to see sharp primes being re-leased at only ~$200 US. In fact you can Pre-order this lens already at BHPhotovideo (Click Here) or at Amazon (Click Here)

Upcoming Articles and News:

I’ll get this Sigma 30mm lens and review it myself very shortly, so look out for that article! I Also have the LA-EA2 A-Mount Lens adapter coming along with the A-Mount 70-400mm lens Today, and I can’t wait to try it out on the Nex-5n!!

I’m also planning on reviewing the Fuji X-Pro 1 which comes out tomorrow, and then the Olympus OM-D E-M5 which comes out in about 2 weeks. Let me know what you think as I don’t have to review those cameras, but they look awesome and compete directly with the Nex-7 and Nex-5n so it makes sense to me?

  1. Given ‘s recent tests that show most of Sony’s E mount lenses are woefully inadequate for the NEX-7 – something I expected to come out sooner or later – it’s nice to see that the shots with this lens were taken with the NEX-7 and seem quite okay. I’m hoping to see some more in-depth testing on this lens. We need more quality E mount lenses for the NEX-7!!!!

    Hey Spike,

    Thanks for your comments.
    I don’t think their as woefully inadequate as is being let opn. I have the Nex-7 and have done extensive shooting with it using a variety of E-Mount lenses and my Pro Canon Glass. The Canon Glass is obviously way better, but the Standard E-mount lenses performed pretty solid in the real world on the Nex-7. In the Lab is another story where they can get picked apart. The 24mp sensor is going to find some flaws that would not show up other wise. The D800 36mp sensor camera is going to have the same issue when people start using sub-par lenses on it. Can you imagine how hard that 36MP Sony sensor is going to push the lenses!!


    • Jay, I know what you’re saying. I have the NEX-7 with 2 Sony lenses. I also shoot with the Nikon D700 with several lenses. Of course I don’t expect the same results from the D700 and NEX-7 and I have gotten some shots with the NEX-7 that I’m proud of. That being said, I’m hoping for better glass (keeping in mind that the presumably wonderful Zeiss 24mm is out of my price range at the moment).

      • Jay


        If the Zeiss is out of your price range (Can’t blame you) then your best bet for quality is to get some adapters and Legacy glass (Nikon in your case) You will lose the small size unfortunately, but it’s nice to have the option to use all sorts of killer optics on the one camera body.

        Which lenses you have?? Just curious 😉


  3. I already had a few shots with the Sigma. I really love it on my Nex-7. It is not as sharp as the 50mm f/1.8 but the performance is better than the 18-55mm. I am already looking forward on how you like the glass.
    i hope Sigma or Sony release a Macro pretty soon.

    • Jay


      Thanks for the comments!! It looks significantly better than the 18-55mm in the sample shots I think. Sony does have the 30mm Macro lens which is pretty god for the money, but I think I higher focal length lens is a must for the E-Mount Line-up!!

    I too am suffering from the not so good lens options of nex. (Nex 5n owner) zeiss 24 is pricey.

    One of the best lenses ever reviewed on the photo zone website is 31mm Pentax. And I saw it also exists in gray finish. Price range $600-$800.

    What do you guys think about using it on Nex?–test-report

  5. Mike Stern

    I think I was dreaming on the price. $1100

  6. Mike Stern

    Seems like you skipped my first comment. My comment above was an add on to my own comment. Can you fix this do you think?

    My comment was about potentially using a Pentax 31mm lens on nex. Hope you can find it.
