Voigtländer VM 35mm f1.7 Ultron asph. review (for Leica M)


Image Property of Voigtländer

In the end of 2014 i did a review of the Zeiss 35mm ZM Distagon and it turned out that this was a great lens. Now, about 9 months later, i have the chance to write about another alternative for the M mount.

It took me quite a while before i first tested a non Leica lens on my M. There was little reason because i was always happy with Leica. Shure these lenses are pretty expensive but you get what you pay for and they hold up in value very well. Still there are good and more reasonable priced alternatives out there on the market.

While Zeiss was always known for quality glass with its own optical character Voigtländer seemed to be a bit behind, both in terms of build and optical performance. But like in the car industry times are changing and new products from less renowned companies surprise us. So after hearing good things about the new Voigtländer Ultron i thought it would be time to give it a try.

Build quality

Note that i can only speak about the chrome version of the lens which is made out of brass. There also exists a black version that is made of aluminum. I went for the chrome one because i thought it would look cool on my M and i loved how the latest edition of the 50mm Nokton looks like. In fact the Nokton and this lens are very comparable in look and feel.

The chrome version of the Ultron is noticable heavier (330g) than its black sibling (238g). Both are well made but maybe not on par with Leica glass (or Zeiss for that matter). The aperture ring is solid and smooth at the same time although the focus ring feels a bit harsh in comparison. There is nothing wrong with it, it is just how it feels to me after shooting Leica lenses almost exclusively. The filter thread has a size of 43mm which is uncommon for Leica mount. The lens is quite small with a length of 50.6mm and comes shipped with a (screw on) metal lens hood. It feels very dense and solid in the hands and works just fine.

Optical quality

Now the question is how well compares the 980 US dollar Voigtländer lens to the rivals from Zeiss and Leica ?

The new Voigtländer starts with a 1.7 aperture and wide open it is very compareable to the fantastic Zeiss in terms of sharpness. Overall performance is improved when stopping down and from 2.8 on it is as sharp as it gets, even on pixel level and even in the corners of the frame. Micro contrast is also on a high level but i usually like to add a bit clarity in post.

Colors look very true to life with this Voigtländer lens. I had my problems in the past with lenses from that company but this one is on a new level. Even better than the 50mm Nokton 1.5 asph. (which was already a step forward). The lens shows no visible focus shift also. Well done.

The lens has a good flare resistance when you shoot against the sun. At small apertures and in very contrasty scenes you can find color fringing occasionally. In most shooting situations you will see none. With its ten aperture blades it easily creates nice looking sunstars not only at f 16. The overall rendition is very organic with just the right contrast. Bokeh is also pleasing for a 35mm lens.

At f 1.7 there is visible vignetting. That is expected. It goes away when you stop the lens down. In actual photography it will not be an issue but when you shoot white walls this lens shows also a minor magenta color cast in the corners of the frame. I coded the lens as a 35mm Summicron asph. and it helped (see images below).

If you are sensible to distortion and want straight lines right out of the box, here is good news. Distortion is on a very low level and the little there is can easily be fixed in LR if you want perfection.

The bottom line

The Voigtländer VM 35mm f1.7 Ultron asph. is a strong performer. It is sharp, has good color and contrast, a nice bokeh and handles nicely. It is not a f 1.4 lens like its more expensive competitors but that does not matter much to me. With its compact size it feels very balanced on a Leica M and it also does not block the view finder much. It comes with a lens hood and a three years warranty (in Europe) for a very reasonable price. What is not to like ? Highly recommended.

  1. Hi Markus,

    Great write up on the 35mm Ultron! The photographs accompanying this review are excellent and definitely demonstrate this lens’ abilities. Thanks for sharing with us,

    Best regards,



  2. Hello Patrick,

    thanks for your feedback. It really is a capable lens. It is a small and compact solution for other mirrorless cameras, like the Fuji X-Series or the Sony A7-Series, too. Gives a different signature to the images compared with first party lenses.

  3. Nice write up! I had the lens , sold it and bought it again. I own a summarit 35 , great lens . But sometimes you just need the extra speed specially when you use an M9 where high ISO is not recommended . The colors need some tweak in LR but you get a wonderful rendering lens .
