About Zeiss

Biogon T* 2/35 ZM The powerful all-rounder... The lens of choice when a single lens has to do it all. This 9-element lens based on the Carl Zeiss Biogon design features outstanding image quality, high speed at a small size, stunning resolving power and next to zero distortion a unique combination for an M-bayonet camera. Ideal for travel, photojournalism, human interest reportage, outdoors and indoors photography, and documentation.

Why M-mount?
• For more than 50 years now, passionate 35 mm photographers have been embracing the M-mount rangefinder camera system. From the lens designer's perspective, a rangefinder camera offers an exciting advantage over single lens reflex (SLR) cameras: more space. After all, there is no moving reflex mirror and drive mechanism. This allows for a short distance between the last lens element and the film meaning more opportunities for designing of superior lens types, including high performing wide-angle lenses.

A passion ready for the challenge
• For our lens designers, the chance to develop the Carl Zeiss family of T* ZM-mount lenses was a dream come true. They were free to follow their passion in pursuit of perfection in lens performance, taking full advantage of our uncompromising symmetric lens designs. The only limitation was to reserve 15 mm in front of the film for the TTL exposure metering, commonplace in M-mount cameras. The result is a complete range of the most advanced M-mount lenses ever made.

Superior in every way
• The Carl Zeiss range of T* ZM-mount lenses offers the highest possible standards in terms of performance, reliability and, of course, image quality. Quite simply, they are superior in every way. You can count on highly advanced flare control for crisp and brilliant images, for example. And virtually zero geometric distortion, ensuring precise accuracy when reproducing shapes especially useful when photographing products and architecture.

• Carl Zeiss T* ZM-mount lenses are specifically designed to minimize focus shift with aperture changes an important innovation withbig benefits for rangefinder photography. As a result, you can expect improved accuracy of the rangefinder-defined focus. While the precise 10-blade aperture with 1/3 stop interval click stops ensures exact exposure. For reliable performance, Carl Zeiss T* ZM-mount lenses are designed with a wear resistant filter mount and an extremely accurate rangefinder coupling mechanism.

Very Good


from Rhode Island  -  Photo Enthusiast

From the rolls I've developed so far, the negs look on par with the Leica 35mm f/2 asph that I owned. Not bad for 1/3 of the price. The build quality is probably just below the Leica, but certainly above some of the CV lenses that I have owned.

Sharp and contrasty, right to the corner


from Philly  -  Photo Enthusiast

My last camera had a 35mm lens that was a poor performer, so this lens is a real treat. Check the MTF charts on the Zeiss site for the fuller story, but basically the lens is superb. I use it mostly at f2.8 and f4 where the lens really shines, with excellent out of focus rendition. It's nice to be able to go to f2 in a pinch, but that's rare for me. The lens has essentially no distortion, making architectural photography (or any photography with straight lines near the edges of the frame) easier. The only gripe I have is the abysmal lens cap which is an embarrassing afterthought of a design for such a nice lens. It's so frustratingly bad I don't use it at all; instead I use the combination of the lens hood and a filter, which actually works surprisingly well. It's a great lens, which I highly recommend.

The best lens I own


from Pittsburgh, PA  -  Photo Enthusiast

I recently bought a used Leica M8 and wanted a 35mm lens for my standard lens as they are roughly normal on a 1.3 factor camera. I evaluated this lens and the Voigtlander 35mm f/1.2 Nokton and chose this lens because 1.) it was sharper from f/2 to f/4, 2.) it weighs half as much, and 3.) it's build quality was superior (specifically, the aperture ring and focus tab). If you are considering both lenses, I think that ultimately the weight and whether you really need apertures below f/2 (the Nokton is soft here) are the main factors to think about; they are both fantastic lenses. Bottom line -- this is my favorite lens and I highly recommend it. Sharpness This lens is very sharp even at f/2 with improvement until around f/4. By f/2.8 it is extremely good, and even at f/2 you will be hard pressed to find fault with the sharpness unless you are doing a controlled test. A friend of mine described my photos with this lens as "scary sharp". This lens will let you see extremely fine details throughout the entire frame at f/8. I've read some reports that this lens is softer than the Nokton at f/2, but not my copies. Color and Contrast Zeiss lenses are famous for their contrasty look that makes colors pop, and this lens is no exception. Subjects tend to take on a 3D look due to how this lens transitions between in and out of focus. This lens has noticeably more contrast than the Nokton (of course you can tweak this when post-processing if you want more or less). Construction, Size and Weight This is a small, lightweight lens, though not quite as small as the Leica 35mm Type 4 Pre-ASPH. It's 1/2 the weight of the Nokton which is really huge and protrudes into the viewfinder. It is made out of metal with no plastic to be found, except for the lens cap (see Cons below). The aperture ring has a very nice resistance to it where each click represents 1/3 of a stop. You can easily select the aperture you want without looking if you count clicks. It focuses quickly and accurately; I swear I take more in focus pictures now than with my Canon 20D and autofocus lenses. The Nokton was slightly off at infinity (a common problem, apparently), but not this lens. The focus ring is nice and smooth with a focus tab (a bump on the focus ring) which lets you feel roughly where you are focusing (e.g. 6 o'clock is roughly 6 feet away). This greatly aids pre-focusing (guessing the focus before you look through the viewfinder). I don't ever want to shoot a rangefinder lens that lacks a focus tab from now on. Bokeh The bokeh is excellent. Out of focus lights are nearly perfectly circular. It's hard to get a lot of background blur due to the 35mm length and the short focusing distance, but given enough distance between your subject and the background you will get some very pleasing blur. Chromatic Aberration I haven't noticed any significant chromatic aberration with this lens. When shooting subjects outside on bright days, no purple fringes have reared their ugly heads yet. Distortion None -- this lens has 4x less distortion than the current Leica 35mm Summicron! Flare I'm not a real stickler for flare, but this lens has the best flare resistance I've ever seen. I've shot directly into the sun with a UV/IR filter and still didn't get any flare. I've only taken one picture with any flare so far which was a night shot directed at a bright light (also with filter). If you care about minimizing flare, this is the lens for you. Cons * The focus ring is slightly harder to turn when the camera is held vertically. In practice I haven't found this to be a problem and have taken plenty of great portrait orientation photos. * The lens cap is pretty bad. It's made of plastic and is hard to secure properly. It does fit when the lens hood is in place, which is a plus. * The lens hood is expensive. As a Canon shooter, I'm used to paying extra for lens hoods. I'm also used to them being plastic, which is not the case here. The lens hood is metal and vented. It works well and it looks very nice. It feels like less of a rip off than the Canon lens hoods due to its high quality construction.

Peng W  I lost the front cap. Which one would be a fit for replacement?
NORMAN R  I think I needed a 43mm to 46 mm adapter and then I prefer screw on lens caps - I used 46 mm to match my other leica lenses
