Voigtlander Ultron 21mm f/1.8 Reviews

Superior quality at a great price

I use this lens on my sl2, and it renders images beautifully. It handles the extra mega pixels of the sl2 very well, and produces great colors and contrasts.

I love this lens so much.

I shoot with this and an A7. It handles like it was made for this camera body. For people shots, f/1.8 is highly usable and in the context of street photography it's sharp enough for low-light work. Its distortion is negligible and I feel comfortable using it for interior architecture as well. It's not a perfect 5 because it does have a pretty strong vignette until it's stopped down f/8 and sometimes displays color fringing. Both of these are easy to correct in post or by using the Lens Correction App in camera, but it's an extra step either way. It makes up for this in its rich and contrasty color rendition. Also, because this is a rangefinder lens, it bears note that the extreme corners are not as sharp on an A7 body due to the thicker filter stack. But, honestly, unless your primary use for this lens is fine art landscapes, you won't be disappointed. It's a beautiful, compact, and sharp tool. I recommend using it with the Voigtlander Close Focus Adapter if you're using it on an A7 series camera.

Substantial Lens. Very Good Optics.

Although I already have a Voightlander 21mm f/4.0 lens purchased several years ago, the excellent review by Sean Reid (Reid Reviews) and my desire for a larger and faster lens prompted me to make this purchase ... that and a sale going on at the time! The first thing I did was to set up my camera indoors on a tripod and compare their optics. The f/1.8 lens, while acceptably sharp fully open, improves at f/2.8 and especially at the same f/4.0 aperture as the smaller lens. I believe, however, that at f/4.0 the edges are sharper with the larger lens. Color and contrast with both are very good. Focus is maintained with change of aperture from its f/1.8 maximum, allowing sharp focus wide open then stopping down for desired depth of field. This is a very substantial lens, much larger and heavier compared with the 15mm f/4.5 and 35mm f/1.7 Voightlander lenses also now in my collection. I don't mind that, because it fits my large hands better than the smaller lens, with control rings more distinct and more widely separated than those crowded in the f/4.0 lens. The aperture ring's half-stops are more positive and the focusing ring is broad and operates smoothly, I also much prefer the abbreviated built-in lens hood, as opposed to a screw-on or clamp-on hood that takes up more room. The question to be answered is whether its increased bulk, weight and additional cost can be justified in light of the very good optics of the smaller 21mm f/4.0 lens. For low light conditions and street shooting the more precise focusing and faster shutter speed favor the larger lens. With the 1.5 crop factor of my Fujiflm X Pro2 with M-adapter, this lens' 35mm equivalence is 33mm, which means it will be used often. For me, all of the above factors make the choice of the f/1.8 very sensible and preferred over its smaller sibling. For others, the smaller size and cost might lead them to choose otherwise. The good thing is that there is no wrong choice here. I gave this lens a 5 star rating for its very good optics, top notch construction and excellent control ring function.

I bought this lens as an alternative to the equivalent Leica lens and I am very happy with the decission. When set in the Leica camera as a 21 or even 28 mm lens it works flawlesly. A great lens for its price for the Leica M system

Perfect for interiors

I bought this lens mostly for interesting interiors--it's fast enough to use indoors even with slow film (the attached was taken with TMax 100, handheld at, I think, 1/30 and f/1.8). It pairs well with the Bessa R4M, which has frame lines at 21mm. Really remarkable, unique lens. It also has an extremely close minimum focus, but note that the focus range actually extends beyond the minimum point of the rangefinder coupling. In my experiments so far I haven't found this to be a problem--it's just about a foot between the rangefinder limit and the lens limit, so that's easy to estimate.

I bought this lens for use with Fujifilm XT-3. ...

I bought this lens for use with Fujifilm XT-3. Focus peaking is very hard to do unlike other lenses like Voigtlander 58 1.4. The distance scale seems off by 1 or 2 meters! For example, if I want to focus at 3 meters, I must set the distance on the lens at about 1.2 meters. Why is this happening? Could it be because of the adapter? I am using K&F Concept Leica M to Fuji X adapter.
Asked by: Andrey
Yes, the K&F Concept Leica M to Fuji X adapter, is causing the "distance Scale" on the Voigtlander Ultron 21mm f/1.8 Lens to be inaccurate.

I had a 21mm voigtlander color skopar lens which when mounted on a m10 had bad purple color vignetting. Does this lens have the same or similar problems?
Asked by: David
The Voigtlander Ultron 21mm f/1.8 Lens has some lateral color fringes (secondary lateral chromatic aberration), visible if you look for this sort of thing when shot digitally, but otherwise it's invisible for normal use.

Is it coupled with the Leica M10 range finder?
Asked by: Anonymous
Wrong answer above. The widest FOV of the built in VF is 28mm, but you could use that if you want, even though the image will show more than is indicated in the VF. You would need to use an external 21mm VF in order to be accurate, and the Ultron will be accurately coupled to it, subject to the parallax inherent in all rangefinders.

I read most reviews for this lens, and lot of people using this lens with SONY A7 body.So, I had SONY A7 also. Do I need some adapter for A7 body or just fit in with A7 body without converter or adapter?
Asked by: SOON Y.
Yes, you do need an adapter for the Sony A7. I use it with my Sony A7R with an adapter I got online. This lens fits M-Mount and this is the reason for the adapter.
