Review Summary
2018-01-25T15:42:36
Zeiss's Biogons are fantastic and are my choice for M mount super and ultra wides. I had previously owned a Contax RTS III system and was wowed with its Zeiss optics such as the Distagon 28mm f/2.8 (which I later adapted to Canon bodies as well). Fast forward ten or so years when I started building up a Leica system and Zeiss just happened to (re-?)launch the Ikon system and the ZM lenses. For a short time I owned an older 2nd version Leica 28mm f/2.8 that was a nice introduction to M mount wides but it was quite soft in the corners and I always felt like 28 perhaps wasn't as wide as I'd like so I sold it and bought the Zeiss 25/2.8. Initially I used it on my M6 and then dedicated an M2 to it and its VF. I also used it on a NEX-5 body before I got a FF Leica body. In all situations and mediums it never ceased to impress me with its sharpness, contrast, and color fidelity. Now I also use it on an M-D 262 body and it really shines. I just added the 21/2.8 Biogon and it, too, is an inspiring and impressive lens. I've auditioned the various Leica super wides and while they are also naturally very impressive, the gap in performance vs. the gap in price leaves me very happy with my decision to use Zeiss and I'm left not wanting in the slightest. Close up performance is superb and the bokeh is smooth and creamy. Hyperfocal shooting is also excellent. At f/11 everything from 3 feet to infinity is tack sharp. Especially in super and ultra wides for M mount, the Zeiss Biogons, in my opinion, are right up there with the best. They give the Leica equivalents some serious, serious competition.

Be captivated by the exceptional quality of the 25mm f/2.8 Biogon T* ZM Lens for Leica M, Silver. This lens is a specialist in architecture and landscape photography, offering unparalleled brilliance and resolution at all apertures. As a powerful companion to the 35mm "standard wide-angle" lens, this 9-element lens is based on the symmetric Carl Zeiss Biogon design.
Experience the stunningly high image quality and virtually invisible distortion that make this lens an indispensable tool for capturing wide vistas, breathtaking landscapes, dynamic cityscapes, and intricate architecture. The M-mount design, embraced by passionate 35mm photographers for over 50 years, offers a unique advantage for lens designers: more space. Without the need for a moving reflex mirror and drive mechanism, the distance between the last lens element and the film can be shortened, allowing for superior lens designs, including high-performing wide-angle lenses.
Our lens designers relished the opportunity to develop the Carl Zeiss family of T* ZM-mount lenses, pursuing perfection in lens performance and taking full advantage of our uncompromising symmetric lens designs. The result is a complete range of the most advanced M-mount lenses ever made, offering the highest possible standards in terms of performance, reliability, and, of course, image quality.
Expect highly advanced flare control for crisp and brilliant images, and virtually zero geometric distortion, ensuring precise accuracy when reproducing shapes - a feature 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 with significant benefits for rangefinder photography.
The precise 10-blade aperture with 1/3 stop interval click stops ensures exact exposure, while the wear-resistant filter mount and an extremely accurate rangefinder coupling mechanism guarantee reliable performance. Experience the superior quality of the 25mm f/2.8 Biogon T* ZM Lens for Leica M, Silver, and elevate your photography to new heights.
