An exhaustive list of the Zeiss Ikon cameras from the 20th century would be lengthy. The older Zeiss ikon cameras such as the Contax IIa were known for their quality build and using Zeiss' outstanding optics. These early rangefinders developed a reputation and a following the likes of which are matched only by Leica and Hasselblad. By the turn of the 21st, Carl Zeiss sought to introduce a camera that would compete with the more modern, electronic cameras with automatic exposure. The result of combining Zeiss' history of quality and up-to-date features was the Zeiss Ikon ZM and its simpler variant the Zeiss Ikon SW.
First hitting the shelves in 2005, the Zeiss Ikon ZM offers a full range of shutter speeds from 1 second to 1/2000th of a second. With its vertically travelling shutter made of thin metal blades, the ZM has a maximum flash synchronization speed of 1/125th of a second. This is faster than its contemporaries at Leica, which were 1/50th of a second. Mainly manufactured by the company Cosina, the Zeiss Ikon ZM shared a metering system with several other cameras, most notably the Bessa R viewfinder/rangefinders. This system meters off of an 18% gray shutter blade for the best accuracy.
The ergonomic design of the Zeiss Ikon ZM follows the comfort and usability of their 20th century cameras. The film wind lever has a much shorter "throw" than the Leicas of the same era and the shutter button is placed comfortably on the top cover within easy reach for most users. Several ounces lighter than its Leica counterparts, the handling of the ZM is a real pleasure.
Zeiss gave these cameras the same M-mount that Leica developed, so changing between Zeiss and Leitz glass is easy. With the exception of the 90mm and 135mm focal lengths, the same framelines that set themselves automatically on a Leica M camera appear in the Zeiss Ikon ZM viewfinder. Add to that the automatic parallax correction and the ZM is a fully capable camera that can hold its own with any rangefinder on the market.
The production of the Zeiss Ikon ZM ended in 2012 and during its eight year run only one other model of the ZM was made. The Zeiss Ikon SW camera was very similar to the ZM in its construction, but it did not have a built-in rangefinder or viewfinder. Designed primarily to use wider lenses that the ZM, the SW and its finders could easily accommodate shooting with lenses as wide as 15mm with the same lightweight build and excellent metering.
While not as well-known as its German cousin the Leica M-series, the Zeiss Ikon ZM is truly a workhorse of a camera that belongs in the same discussion with any other modern rangefinder. Becoming a Zeiss convert will introduce any photographer into the world of easy-to-use, well-built, and well-designed cameras.

TTArtisans 28mm f5.6 on a Zeiss Ikon ZM - Test # 5 - Wide Open
Shooting the TTArtisan 28mm f5.6 for Leica M-Mount wide open at f/5.6 is the only to achieve out-of-focus areas with this lens. While the slow maximum aperture of f/5.6 does not lend itself to indoor photography, it is possible with proper technique. This image was shot at f/5.6, 1/15th of a second.
Made with: Zeiss Ikon ZM, TTArtisan 28mm f5.6, Ilford XP2
TTArtisans 28mm f5.6 on a Zeiss Ikon ZM - Test # 4 - Stopped Down
Here we see the performance of the TTArtisan 28mm f5.6 for Leica M when stopped down to f/16. At f/16, everything from 3ft - ∞ is in focus.
TTArtisans 28mm f5.6 on a Zeiss Ikon ZM - Test #3 - Moment
One of the biggest advantages of wide-angle lenses is their expansive depth-of-field: at small apertures, almost everything will be in focus. Without having to worry about precise focus, a photographer can pre-frame a street scene and wait for the "decisive moment" to appear. This image was made at f8, and focused at 6ft.
TTArtisan 28mm f5.6 Lens on a Zeiss Ikon ZM - Test #2 - Backlight
The TTArtisan 28mm f5.6 Lens for Leica M-Mount has controlled flare admirably in our testing. This image, shot into bright backlighting without the lens hood (which doubles the size of the lens!) evidenced no visible ghosting. The front element of the TTA is quite recessed into the barrel, which likely aids flare performance without the hood.
TTArtisans 28mm f5.6 Lens on a Zeiss Ikon ZM - Test #1 - Interior
While the TTArtisan 28mm f5.6 M-Mount is limited to a maximum aperture of f5.6, ambient-light indoor shots are still possible. This image, taken at 1/30th and f5.6, shows how the 28mm wide-angle can create a sense of depth in space without distorting human subjects unnaturally.
It is usually a safe assumption that anything in the Leica M-mount system is going to be worth noticing, and the Zeiss Ikon ZM doesn't disappoint. It really is a fine rangefinder that holds its own in conversations with such cameras as the Leica M7, of which one could consider it a rival.
Is it objectively overall better than a Leica M7? Probably not. Is it better than an M6 or MP? We would say that it isn't. It is well built and, arguably, the best camera ever made by Cosina in this category. It does have a faster shutter, at 1/2000, than a Leica, though that shutter is metal and therefore a bit louder. It has an incredible viewfinder, it is the real selling point for this camera. The viewfinder is big and crystal clear. The other controls like shutter release and film advance are more subjective. You might like them more, you might like them less. As we said at the get-go, the Zeiss Ikon is a camera worth noticing. Don't compare it to the Leica for a few minutes and you'll appreciate how light but strong this camera feels. You'll marvel at the viewfinder and delight in the crispness of the shutter. It is a great companion as far as cameras go and we never even mentioned the Zeiss glass that is on the camera and all those superlative qualities.
