Sign me up. Since I discovered the joys of being able to shoot on the m11 monochrom at f 5.6 at night with minimal noise at ISO 20k up to 40k, this lens will be perfect for nighttime walkabout and street photography.

Absolutely, exactly what I’m thinking. The M11M is awesome for 1) character lenses (pre ASPH luxs, old Crons, Summarons, etc) and 2) being able to use slower/lightweight lenses at high ISOs with very little impact to image quality. M11M is unreal

Minimal Focus Distance: Resolution and Contrast

The Voigtlander 50mm f/3.5 APO-Lanthar offers impressive versatility, focusing as close as 0.35 meters and providing a 1:4.8 magnification (0.21x), which edges into macro territory. It’s notable how the lens maintains high image quality with excellent aberration control at both its minimum focus distance using Live View and 0.7 meters, the closest focusing distance for the Leica M rangefinder. This is achieved despite the absence of a floating element design or aspherical elements.

For this review, I tested the lens at its minimum focusing distance of 0.35 meters and at 0.7 meters at apertures f/3.5,...Show more →

I’m so excited to use this lens. Not buying this one from Japan. Looks like my 50 2.2 isn’t going to be shipped until late September.

The macro reproduction ratio for the 50/3.5 APO is, by my calculations, 1:4.6 - due to the actual focal length being 51.3mm.

Leica's SL 50/2 APO is 1:4.8; and the Summicron-M APO 50/2 is 1:12, using actual focal lengths based on stated AOVs. The Voigtlander 50/2 APO (M) figure is 1:11.8, using the same method.

Flare Resistance


Usually, 50mm lenses with fewer elements and simpler designs offer great flare resistance, especially if they have modern multi-coated elements. However, this isn't always true for all symmetrical designs. For example, the Zeiss 50mm f/2 Planar and Leica 50mm f/2 Summicron aren't known for their flare resistance.

The Voigtlander 50mm f/3.5 APO-Lanthar has fewer elements than the Voigtlander 50mm f/2 APO-Lanthar and has an optical design reminiscent of the symmetrical "Planar." This made me wonder if it would perform as well as the f/2 version in terms of flare resistance. However, my tests show that both lenses have similar resistance to veiling and ghosting. This is great news for the 50mm f/3.5, as the f/2 version is known for its excellent flare resistance.

Cosina prioritizes flare resistance in their optical designs, along with excellent multi-coating. Given the small front element and simpler optical design of the Voigtlander 50mm f/3.5 APO-Lanthar, I expected it to perform well. After many days of testing against light at different times of the day, I can confidently say that this lens is indeed flare-resistant, especially compared to other 50mm M lenses. I found it challenging to produce significant veiling flare unless I pushed the lens to its limits (as shown in a sample below). For these tests, I didn't use the lens hood when comparing to the CV 50mm f/2 APO because I wanted to see if the hood was even necessary.

In the images below, we will analyze the flare resistance of the Voigtlander 50mm f/3.5 APO compared to the Voigtlander 50mm f/2 APO. I was unable to induce any ghosting with the f/3.5 lens, except in one instance where I noticed a ring flare, likely caused by the chrome ring of the lens. This issue probably won't happen with the black models or when the hood is attached, but I'll confirm it when I test the black versions.

Philip is likely quoting Australian retail prices that he got from a dealer there.

There are ways to buy from Japan for delivery to the US, but pretty much all the options will involve using a freight forwarding service because the vast majority of Japanese online shops don't ship internationally. Buyee through Map Camera used to be a good option but Map Camera stopped offering new stock from most brands through this service. If you plan to buy a lot of gear, it might be worth flying to Tokyo for a few days and shopping in person to take advantage of tax free shopping which will not be possible with online orders through a freight forwarder (because the retailer is shipping the product to the freight forwarder's domestic address, therefore 10% consumption tax applies). Whatever the case, you should carefully price shop because some things can be had for good savings from Japan, while other things are very similarly priced to here. For whatever reason, a lot of Voigtlander and Zeiss is, or has been, somewhat cheaper in Japan. But once you add freight forwarding costs, plus the hassles with returns or exchanges, if even possible, it might be worth spending a little more to buy domestically in exchange for better support if something is not right with your copy.

These lenses are not available anywhere as yet, so far as I know. People want to know the price level, so I gave the thread our firm prices from the CV distributor. Best to buy in your own country or jurisdiction, in fact Cosina polices this market separation pretty well from what I can see. Just wait a bit.

Above, the more distant parts from the flare source appear to settle down faster in the 50/3.5 images than in those from the 50/2 APO. The flare actually looks more like an integral and intended part of the image. These tests show that sound lenses open up avenues of shot-making that were otherwise off-limits, or required extensive work in post just to get back to square.

For the member asking about reasons to replace his APO-Summicron-M Asph, Diglloyd's 2020 page has a remarkable demonstration of how bad flare can be, even after the maker tried to fix it years earlier:

I've owned the Voigtlander 50mm f/3.5 Heliar for a couple of years but haven't done a serious review on it. In my experience, here’s how the Voigtlander 50mm f/3.5 APO-Lanthar compares optically to the Voigtlander 50mm f/3.5 Heliar:

Minimum focus distance: The APO-Lanthar Type II focuses at 0.35m, significantly closer than the Heliar’s 0.7m. This closer focus distance makes the APO-Lanthar more versatile when using LiveView.

Rendering: The APO-Lanthar provides a smoother transition zone compared to the Heliar. While this is largely a matter of personal taste, the Heliar is known for its distinctive character, including more noticeable bokeh outlining and higher optical vignetting (swirling).

Resolution/Contrast: Both lenses perform well in resolution and contrast, but the APO-Lanthar has the edge in overall performance wide open.

Field Curvature: The APO-Lanthar has a flatter field curvature, whereas the Heliar shows a wavier curvature.

Flare Resistance: Both lenses handle flare effectively.

Distortion: The APO-Lanthar shows no distortion, while the Heliar also performs well in this regard.

Both the 50mm f/3.5 Heliar and the 50mm f/3.5 APO Type II have their aperture and focus controls on the same ring. However, the Heliar features a clickless aperture.

The Voigtlander 50mm f/3.5 Heliar has been discontinued, likely because Voigtlander now offers a superior 50mm f/3.5 lens. I may compare them side by side in the future, though I can’t guarantee it at this time.

These images were captured at high noon to achieve vivid and high-contrast results, with a few slightly cropped. I used my Sony A7R II UT, relying solely on natural lighting for all shots.

As anticipated, there is noticeable vignetting when shooting wide open at f/3.5, which significantly reduces by f/5.6. Vignetting was left uncorrected to showcase the worst-case scenario.

The Voigtlander 50mm f/3.5 APO-Lanthar is available in two versions. Type I has a minimum focusing distance of 0.45m, while Type II can focus as close as 0.35m. This difference is quite significant, and to illustrate it, I've included a quick test showing how much closer 0.35m is compared to 0.45m.

While this may not be critical for everyone, especially those focusing with the rangefinder, both 0.35m and 0.45m provide a considerable improvement in distance and subject magnification compared to the standard 0.7m.

the minimum focus distance of type II is especially what I want. My only complaint with the steel rim reissue and other lenses is the 1m min focus distance.

And the vignetting at f3.5 is fine with me, I'm one of the oddballs who actually likes vignetting.

Infinity Resolution and Contrast compared to Voigtlander 50mm f/2 APO-Lanthar on Leica M11 (60MP)

After comparing the resolution between the Voigtlander 50mm f/2 and the 50mm f/3.5 APO-Lanthar lenses at infinity distance on the 40MP Leica M10-R, some of you observed that the real-world performance of the CV 50/3.5 APO-Lanthar appears to surpass its simulated MTF graph, especially when compared to the CV 50/2 APO. There was speculation that a higher MP sensor might reveal a more noticeable advantage for the CV 50/2 APO, given its stronger MTF.

Today, I had the opportunity to test these lenses on a Leica M11. I focused both lenses exactly as I did when using the M10-R. I was reminded of how much I dislike the M11's color rendering with its noticeable magenta tint, but that's beside the point.

The results of this comparison were somewhat surprising to me, so I repeated the test several times, also comparing with the M10-R. The lenses were focused identically at their hard stops on both cameras, eliminating the possibility of focusing errors. My analysis shows that on the M11, the center area resolution remains very similar, with perhaps a slight improvement on the M11. However, in the mid-field, the M11 resolves high-frequency detail better, while in the corners, I give a slight edge to the Voigtlander 50mm f/3.5 APO-Lanthar, particularly at f/3.5 and f/4. At f/5.6, both lenses produce very similar results. Overall, the findings are mixed, but I suspect that sample variation between lens copies could reveal more differences than actually exist between these two APO-Lanthar lenses.










  1. Distance: Infinity
  2. Focus: Center - Best of three shots at maximum magnification
  3. White Balance: Daylight
  4. Both lenses are perfectly centered, as verified with my decentering test.
  5. Software used: Lightroom with FM Default Landscape Sharpening; all other settings are at default.

    PS: Vignetting, Chromatic Aberration (CA), and distortion were not corrected either in post-processing or in-camera.
