Asahi Pentax's vintage M42 kit — SL body with Super Takumar 55mm f/1.8 in the screw-mount era.
The Asahi Pentax SL with Super Takumar 55mm f/1.8 is a vintage M42 screw-mount SLR kit from the late 1960s. The SL provided match-needle metering with the excellent Super Takumar 55mm f/1.8 — one of the finest M42 standard primes.
The Super Takumar 55mm f/1.8 is an outstanding lens — sharp with the 55mm providing a slightly-longer-than-normal perspective. Super Multi Coating on later versions. The SL body provides CdS metering.
M42 screw mount — universal. The Super Takumar 55mm f/1.8 adapts to all mirrorless cameras. CdS metering in the SL body. Mechanical shutter. The Asahi Pentax name predates just 'Pentax'.
Available used very cheaply. The Super Takumar 55mm f/1.8 is one of the most popular adapted vintage lenses — excellent on mirrorless. Check for radioactive thorium yellowing on some versions. A classic film SLR kit.
