Olympus F.Zuiko 35mm f/2.8 (XA fixed)

Stop this lens down to f/5.6 and the corners snap into a kind of sharpness that feels out of proportion to the camera it lives in. The XA is barely larger than a pack of cigarettes, and yet Yoshihisa Maitani built a six-element F.Zuiko 35mm f/2.8 behind a clamshell cover and coupled it to a real rangefinder patch. That combination is why people kept shooting the thing for forty years instead of filing it under gimmick.

The rendering is high-contrast and a little punchy, biased toward microcontrast over smoothness. Wide open at f/2.8 the center is already crisp and the corners are soft, which barely matters because almost nobody bought an XA to shoot landscapes at f/2.8. By f/8 it is uniformly sharp across the frame and out-resolves most consumer film. Color is neutral and slightly cool, and flare is restrained for a lens with no proper hood: shoot into a low sun and you get a faint veiling haze rather than dramatic ghosts. Backgrounds are honest and unremarkable, neither swirly nor creamy, because a 35mm f/2.8 simply does not separate a subject from its surroundings by much.

It is a documentary and street camera before anything else. You focus with a small front lever and the rangefinder patch, it is nearly silent, and the leaf shutter has no mirror slap, so you can hand-hold it slower than its size suggests. Plenty of photographers who shoot a Leica for paid work have kept an XA in a coat pocket for the moments the bigger body is at home. It gets cross-shopped against the Rollei 35 and the Minox 35, and it wins on the one feature both of those lack: a true coupled rangefinder instead of guess-the-distance scale focus. That alone explains why used prices have crept up.

The honest weakness is the automation. The XA gives you no manual shutter speed at all. It does have a flush lever on the baseplate that adds roughly 1.5 stops for backlit or snowy scenes, so the common "subject is a silhouette against a bright sky" failure has a built-in fix. Beyond that single correction you are at the mercy of a 1979 CdS cell metering the whole frame, so anything trickier means metering the subject yourself rather than trusting the average. Flash is the other catch: clip on the A11 and switch to flash mode and the body locks to about f/4 and roughly 1/30 second, with no aperture or shutter choice left to you. This is where Zone Light Meter earns its place. Read the ambient before you commit, decide whether the scene actually needs the A11 at all, and more often than not you expose for the subject in available light and leave the flash in your bag.

The f/2.8 maximum is conservative for the size, and that was a deliberate trade. Maitani could have crammed faster glass into a bigger body, but the entire point was the clamshell pocket camera. What he delivered instead is a lens that punches above its dimensions once stopped down and asks for almost nothing in return. Four decades on, the XA still makes negatives sharp enough to embarrass cameras several times its weight, and the little F.Zuiko is the reason.
