Optical Vignetting and Specular Highlights shape

When it comes to optical vignetting and the shape of specular highlights, the Voigtlander 35mm f/3.5 Color-Skopar performs quite well as expected for a lens with a modest f/3.5 maximum aperture. In my testing, the typical cat-eye bokeh shape near the edges of the frame stays fairly rounded compared to the center and mid-frame areas. For general use, you’re unlikely to find the optical vignetting or cat-eye bokeh distracting. Specular highlights tend to remain round, especially at close and mid distances, though the effect becomes more noticeable as subject distance increases, as shown in the samples below.

Despite having aspherical elements, this lens shows minimal onion ring patterns in specular highlights. There is some outlining, which might be a positive or a drawback depending on your taste in rendering.

Below are examples showing how the cat-eye bokeh shape changes at different distances:




Out-of-focus rendering near the edges when focusing on a close subject.






Specular highlights become less rounded at far focus.






Some outlining is visible in the bokeh.






Another sample showing bokeh in the mid-zone area.






Corners with subject focused at mid-distance






Corners with subject focused at long distance

Chromatic Aberration Control

Although the Voigtlander 35mm f/3.5 Color-Skopar is not technically an apochromatic design, meaning it does not fully correct for color fringing across all wavelengths, it performs at a level that could be considered APO by most standards. In my high-contrast images, I found only minor traces of color error, which is impressive for a 35mm lens. The f/3.5 maximum aperture helps keep chromatic aberrations under control, but given its extremely compact size, what Cosina has accomplished here is remarkable.

As the samples below demonstrate, it is difficult to detect any purple fringing in focused areas or green and magenta chromatic aberration in defocused zones in front of or behind the subject. In terms of axial chromatic aberration, this lens performs exceptionally well, further aided by its f/3.5 aperture, which naturally makes correcting color errors easier than in faster lenses.

Lateral chromatic aberration, which causes color misalignment at the edges of an image and does not improve by stopping down, is also very well controlled. It didn't even require correction in Lightroom (see 100% crop below)

Overall, while it is not officially labeled as an APO lens, those sensitive to color errors in their images will likely be very satisfied with the level of correction this lens provides.

Sample crops wide open at f/3.5:




Absense of purple fringing at the focused area.






Only traces of green fringing.






Only traces of green fringing.






APO-like correction.






Excellent Lateral CA performance.

Final Thoughts

The Voigtlander 35mm f/3.5 Color-Skopar immediately impressed me with its ultra-compact size, lightweight build, and a smart mix of vintage barrel design and modern performance. At just 14mm in length and weighing 99 grams, it’s the smallest Voigtlander lens ever made, even more portable than the 40mm f/2.8 Heliar and 28mm f/2.8 Color-Skopar. Despite its small size, the solid brass construction gives it a dense, premium feel. The precise aperture clicks and the innovative hood-based adjustment add a nice touch to the user experience. The included extras, like a matching 1mm UV filter and multiple lens caps, are a rare bonus for Cosina. While the lens elements extend into the camera body, it stays unobtrusive on a Leica M and works with E-mount cameras, though with some limitations.

Optically, the 4-group, 6-element design, featuring aspheric and anomalous dispersion glass, offers strong performance. The 10-blade aperture also creates beautiful sunstars from f/4 to f/16. For street photographers, the long 180-degree focus throw and infinity lock might not be ideal, but its compact size, strong performance, and minimal distortion make it a very practical option.

Resolution and contrast tests at infinity showed surprising strengths. When compared to the Voigtlander 35mm f/2 Ultron on a 60MP Leica M11, it holds its own in terms of center sharpness wide open, and it almost matches the Ultron’s overall performance by f/4. Both lenses show minimal field curvature. Compared to the 40mm f/2.8 Heliar, the Color-Skopar offers a flatter field, better center resolution, and stronger corners, outshining the Heliar. On a Sony A7R II (42MP) with a thicker sensor, it does show some increased outward field curvature, but refocusing on the corners restores sharpness, though at the cost of center resolution, unlike the more adaptable 50mm f/3.5 APO-Lanthar. At its 0.7m minimum focus distance, it performs excellently wide open with no noticeable focus shift, which is great for rangefinder shooters. Its mild pincushion distortion is easily corrected, and its flare resistance is impressive, with no ghosting or veiling, even when pointed directly at the sun.

In summary, the Voigtlander 35mm f/3.5 Color-Skopar is an outstanding lens that masterfully combines compactness with excellent optics. It nearly matches the 35mm f/2 Ultron in resolution and contrast, while being far lighter and smaller. The rendering is pleasant, with smooth yet characterful bokeh due to some outlining, negligible chromatic aberration, and pleasingly rounded specular highlights near the corners. While the Ultron is slightly better in focus transitions at f/3.5, the Color-Skopar shines with defined sunstars almost from wide open, and vignetting, which is most noticeable at f/3.5, improves by f/5.6. For hikers or street photographers who value portability without compromise, this lens is a fantastic choice. Its few limitations, like field curvature on thicker sensors and the rare 34mm filter thread, are minor compared to its overall performance. Cosina has delivered on their promise of a retro-inspired lens with modern optics, making it an excellent option for Leica M users and mirrorless shooters seeking quality in a tiny package.


Pros:

  1. The smallest high-performance 35mm lens ever made!
  2. Constructed with Leica-like build quality, featuring a brass barrel and distinctive aperture clicks.
  3. Excellent resolution and contrast, even wide open, from minimal focus distance to infinity.
  4. Low distortion.
  5. The rendering is mostly smooth with a distinctive character.
  6. Flat-field curvature, offering even sharpness across the frame.
  7. Compact design that doesn’t block the 35mm framelines.
  8. Sunstars are sharp and defined from f/4 to f/16.
  9. Excellent flare resistance.
  10. Negligible lateral chromatic aberration.
  11. Negligible purple fringing and axial chromatic aberration.

Cons:

  1. The f/3.5 aperture may limit low-light performance and offers less subject separation compared to faster lenses.
  2. Image quality can suffer from increased field curvature when used on mirrorless cameras with thicker sensor stacks, though this isn’t an issue when mounted on a Leica M.

BTW, I just tested the actual minimum focus distance, and it’s indeed close to 0.7m...slightly shorter at around 0.67m.

An ultron by any other name... what an exciting review. I'm bummed that my 3/30 order is still backordered. Perhaps the word is getting out about this little gem.

Thank you – great review!
How would you compare it in terms of contrast and sharpness to the Heliar 40/2.8 Asph? I find it almost a bit too sharp and contrasty for my taste.

Does the focus lever make the lens incompatible with the Techart LM-EA9?

Thanks for asking! I just tested it, and unfortunately, the lens isn't compatible with the LM-EA9 adapter. The focus lever hits the adapter, so it can’t rotate properly.

Yes, they could have definitely labeled this lens APO-Skopar. Color transmission across reflections is stellar as well.

So is this a 35/3.5 Summaron knock off?

There may be some resemblance in barrel aesthetics, FL, and maximum aperture, but the similarities end there. The Voigtlander 35mm f/3.5 Color-Skopar isn't based on a double Gauss design, and its superior performance and color-error correction don't really match that classic formula.

It's also noticeably smaller and lighter, though that might not make a big difference in practice since both lenses are already quite compact.

Despite the incredibly compact design of the CV 35mm f/3.5, it delivers excellent resolution and contrast, even on today's high-MP sensors. In my tests, including scenes with extreme contrast, its performance is so well-corrected that it feels nearly apochromatic. While the f/3.5 maximum aperture limits its versatility in low light, it remains one of my favorite lenses Cosina has ever made.

Any advice on six bit coding lenses that have a black mount like this one?

Just 'paint' the white code since the black code is already painted.

Just a few things I noticed while watching the review...there's no need to 'lock' the focus ring to infinity when changing the aperture. You can simply hold the ring in place, and this linked design has been used before on lenses like the CV 40/2.8 and 28/2.8 Color Skopar, so it's not unusual or really an issue for street use. Also, the lens isn't made of aluminum; both black and silver versions are brass.

Since the review was done on a Sigma BF body, it would've been helpful to see how the lens performs on a Leica M, which is the system it was really made for. In my own tests, image quality dropped when adapted to the Sony.

I'm wondering what would be a good 6-bit code for the CV 35mm f/3.5 Color-Skopar. Since there’s no Leica 35mm f/3.5 that's already coded, the closest match might be one of the Summarits.
