Zeiss's M-mount wide — same as ID 1344/1450, possible duplicate of Biogon 25mm f/2.8 ZM.
The Zeiss 25mm f/2.8 Biogon ZM T* is a compact wide-angle prime for Leica M-mount using the classic Biogon optical formula with Zeiss T* multi-coating — an affordable alternative to Leica's own wide-angle M primes.
Optically good with the Biogon formula providing characteristically low distortion at 25mm — well-suited to the rangefinder camera format. T* coating controls flare effectively. Sharp from f/5.6 with good centre performance. Rangefinder coupled.
Leica M mount with 46mm filter thread — compact and lightweight at approximately 230g. No electronic contacts — fully manual operation without EXIF communication. All-metal construction with quality Zeiss manufacturing throughout.
Available used at mid-range prices — significantly more affordable than Leica's own 24mm or 28mm options for M-mount. The Biogon formula is well-suited to rangefinder cameras. For budget M-mount wide-angle shooters wanting Zeiss quality.
