Mamiya 105-210mm f/4.5 ULD: medium format telephoto zoom for serious work

Medium format telephoto zooms live and die by their optical construction, and Mamiya built this one with ULD (Ultra Low Dispersion) glass elements specifically to address chromatic aberration at longer focal lengths. That matters when you're working at 210mm on a medium format body, fringing and color artifacts that a lesser lens hides in a small sensor become immediately obvious when your files are this large. The ULD glass keeps color rendering tight where it counts.

The 105-210mm range covers classic portrait focal lengths through medium telephoto compression, and the 645AF mount integration means full compatibility with Phase One digital backs. At 58mm filter thread, standard circular polarizers and ND filters drop right in without stepping rings. For photographers already in the Mamiya 645AF ecosystem, this lens fills the telephoto gap without requiring a switch to primes.

Who It's For

Portrait photographers shooting with Mamiya 645AF bodies benefit from the 105-210mm focal range, which gives working distances that flatter subjects while the ULD glass keeps skin tones accurate. Phase One digital back users get native mount compatibility without adapters or compromises. Commercial and product photographers who need telephoto compression on medium format will find the optical construction handles the demands of large-file scrutiny. Travel photographers working within the 645AF system gain a single lens that spans from moderate to medium telephoto reach.
