Leica Leicaflex SL

This is the heaviest 35mm SLR most people will ever pick up that still feels like it was machined out of a single billet. Leica built the Leicaflex SL the way it built rangefinders, with brass and steel and no apparent concern for what it cost, and the reputation that stuck is exactly that: a tank that happens to be a camera. Surviving bodies still feel dense and tight decades on, the kind of heft that reads as quality until you have carried it up a hill, at which point it reads as a decision you made.

The SL exists because the first Leicaflex had a meter that read the whole scene off the front of the prism and Leica knew it was a step behind the Japanese. So the SL went through the lens. A CdS cell reads a selective central area of the frame at full aperture, essentially a large spot confined to the middle circle, and you balance a needle in the finder against the aperture and shutter you have set. When it works it is a genuinely good match-needle system for its day. The catch is that those CdS cells and their wiring are now sixty years old, and a large share of surviving SLs meter sluggishly, read low, or do not read at all. On a body whose cell has drifted or died, an incident or spot reading from the Zone Light Meter app does the job the meter no longer can: place your shadows on the zone you want, set the dials by hand, and treat the SL as the fine mechanical instrument it still is rather than trusting a tired cell.

The viewfinder is the part that makes you forgive the weight. It is big and bright, and Leica fitted no split-image rangefinder spot, so the whole screen is a microprism field: coarse microprisms inside the central metering circle and finer microprisms across the rest, and focus snaps in and out of crispness across the whole frame. Fast Leica R glass wide open is easy to nail. The shutter is a cloth focal plane running from a full second to about 1/2000, with flash sync at 1/100, and it fires with a firm mechanical clunk and a real mirror slap. Nobody calls this a quiet camera. You feel the mirror in your hands, and across a silent room people look up.

The SL anchored the Leica R mount, the bayonet that carried the whole R single-lens-reflex line for the next thirty-odd years, and the glass is the reason people chase these bodies now. A Summicron-R or Elmarit-R holds its own against anything from that era, and an SL is one of the cheaper ways onto that mount, well below what an R6 or a later body costs. People cross-shop it against a Nikon F or an early F2 and usually decide based on the lenses they already own. The honest weakness is that meter, which is both the SL's headline feature and its most common point of failure, and a proper repair means finding someone who still services Leica electronics from the early seventies, which is neither easy nor cheap. Buy it for the build and the optics, meter the light yourself, and it will likely outlast you.
