Hasselblad / Zeiss Sonnar F 150mm f/2.8

Put this next to the leaf-shutter 150mm f/4 that most Hasselblad shooters actually own and the trade is obvious within one frame. The f/4 CF gives you flash sync at every speed up to 1/500 and a smaller, lighter barrel. This F-series Sonnar gives you a full stop more light and a genuinely shallow plane of focus on 6x6, which on a 150mm lens covering medium format is a different look entirely. It is the portrait lens for people who decided the slower 150 was too safe.

The catch is the body it bolts to. The F lenses were built for the focal-plane 2000-series bodies (the 2000 FC through the 2003 FCW), not the leaf-shutter 500 cameras, which is why this one has no shutter of its own. No between-the-lens leaf means no high-speed flash sync; you are stuck with the body's slow X-sync, usually 1/90 or slower, so studio strobe work loses the thing Hasselblad was famous for. Plenty of people consider that disqualifying. The reward is wide-open speed and a focal-plane shutter that runs to 1/2000, fast enough to shoot f/2.8 in daylight without a stack of ND.

Rendering is classic Zeiss Sonnar in the medium-format idiom. Contrast is high, color is saturated and slightly warm, and behind a head shot at f/2.8 the background goes to an undifferentiated wash with no hard edges to the discs. Wide open it is sharp at the center with a soft, glowing edge to the falloff; stop to f/5.6 and the whole frame snaps clinical. Flare resistance is good but not bulletproof, since the front element is large and the 70mm filter ring sits deep. Shoot into a window and you can pull veiling glare, so a proper hood earns its keep.

Who reaches for it: studio and editorial portrait shooters on the 2000-series who wanted the shallowest 150 in the system, and a smaller crowd of available-light medium-format people who needed f/2.8 indoors. It is a specialist tool inside an already specialist mount. Most V-system portraits in books were shot on the 150 f/4 or the 180 CFE, simply because far more of those bodies existed.

Today it trades as a collector and niche-user lens rather than a workhorse. Prices run higher than the common f/4 because production was small and the focal-plane bodies were never the big sellers, so good copies are scarce. The honest weakness, beyond the sync limitation, is heft and the temptation to live wide open where field curvature and edge softness are real on a flat subject. For people, none of that matters. For a copy chart, it does.

One field note. At f/2.8 on 6x6 in dim light, this lens is bright enough to meter and focus by, but your depth of field is paper thin, so nail the plane on the eyes. Drop your reading into Zone Light Meter and place the skin tone deliberately rather than trusting an average; a stop of misplacement at f/2.8 shows up as a soft eyelash and a sharp ear.
