Carl Zeiss Planar T* 80mm f/2 (645)

Kyocera launched the Contax 645 in 1999, late in the film era, and built the whole system around Zeiss optics with autofocus and a body that handled like an oversized 35mm SLR. The 80mm f/2 was the normal lens that came in the kit, the one Zeiss clearly designed first. On a 6x4.5 frame an 80mm gives you a normal-to-slightly-long field of view, roughly where a 50mm sits on full-frame, but f/2 on that format buys you a slice of focus most medium format shooters never get near. That speed is a big part of why it still sells for real money two decades after the system died.

The rendering is the Planar signature scaled up. Wide open it renders sharp at the plane of focus and falls off quickly, with a focus transition that wraps around a face instead of snapping. Skin gets that smooth Zeiss gradation, gentle micro-contrast that holds detail without going clinical. Stop to f/4 or f/5.6 and the whole frame tightens up; by f/8 it is biting across the field with the flat, even contrast Zeiss tuned the T* coating for. Bokeh is round and clean, no harsh edges, no nervous double-lines in foliage. Out-of-focus highlights stay circular near center and only start to lemon toward the corners.

Wedding and portrait shooters are who actually bought this thing, and a lot of them never sold it. Pair it with Portra 400 in 120 and you get the soft, shallow look that a generation of film wedding photographers leaned on. The autofocus and the f/2 maximum mean you can shoot a dim reception on ceiling-bounce and still nail focus, which most manual-focus medium format setups can't promise.

The honest weakness is mechanical, not optical. There is no leaf shutter in this lens. The Contax 645 ran a focal-plane shutter in the body, so flash sync tops out around 1/125, and if you want full-power strobe at f/2 in daylight you are reaching for ND. The Hasselblad and Mamiya leaf-shutter systems sync flash at every speed. That tradeoff matters at a noon wedding.

It cross-shops against the Mamiya 80mm f/1.9 and the Pentax 645 75mm, but neither carries the Zeiss coating or the build, and Contax 645 body and lens prices keep climbing as the system stays unrepairable. People buy it anyway because of how it draws skin on 120. Practical note: f/2 on this format is a thin plane, and a meter reading half a stop off shows up immediately as a missed eye, so meter for the highlight you care about in Zone Light Meter and place your focus deliberately. The 72mm front takes standard filters if you want a grad or ND for that wide-open daylight work.
