Hasselblad / Zeiss Sonnar CFi 180mm f/4

A photographer lighting a face in a sunlit field wants fill flash and a wide aperture at the same time. With a focal-plane camera you typically cap flash sync somewhere between 1/90 and 1/250 depending on the body, and past that the strobe quits on you. With this lens you sync flash at 1/500, every shutter speed, because the leaf shutter sits between the elements in the barrel and opens fully no matter how fast it fires. Fashion and editorial shooters who worked 6x6 reached for that when the location had hard sun and a battery pack. A Nikon or Pentax tele simply cannot do it.

The optics are pure Zeiss Sonnar logic scaled up for the 6x6 frame: a long, gently telephoto draw that renders skin without the slightly clinical bite of a Planar. Wide open at f/4 it is already crisp across the center with a soft, even falloff toward the edges, and the out-of-focus background stays smooth rather than busy. Stop to f/8 and the corners snap into line, sharp across the whole frame, with the kind of microcontrast that makes detail read without looking harsh. Color is neutral and a touch cool. Flare is well controlled thanks to the T* coating, though a 180 with a large front group and a B60 filter mount still wants the dedicated shade against a low sun.

In the V system this is the portrait and detail lens. On 6x6 the 180mm gives you roughly the field of a 100mm on 35mm, long enough to flatten features and separate a subject from the background, short enough to handle indoors. Wedding and studio shooters loved the CFi version for exactly that. The CFi update (1998 onward) brought the improved ergonomics and the better light trap, but no Databus contacts; on a 203FE or 205 you meter it stopped down. If you want the four-pin electronic version that talks to those bodies, that is the CFE 180, not the CFi.

The catch is reach and speed for what it weighs. At f/4 and 180mm this is not a low-light lens, and the leaf-shutter design caps you at 1/500 where a focal-plane CF body would let the same composition run faster. It is also a big, front-heavy piece of glass to hand-hold on a 500 series. Most people put it on a tripod or a monopod and are happier for it. If you want a true long tele on V the 250 Sonnar exists, but it is slower still, and the 180 is the sharper, more useful length.

Today the CFi 180 sits in the upper-middle of the used V market, cheaper than the 110 f/2 or the 250 Superachromat but well above the kit 80. People cross-shop it against the older C and CF 180s, and the CFi earns the premium only if you value the ergonomics and the cleaner internals, since the glass itself is largely unchanged. For metering, the leaf shutter is the practical note: dial flash sync at any speed up to 1/500 in Zone Light Meter and trust the reading, because there is no focal-plane sync penalty to work around. That trait is why the 180 stayed in working bags long after digital took the studio.
