Verdict
The Pentax SMC-FA 77mm f/1.8 Limited is undoubtedly a special lens thanks to its
very small dimensions combined with an exceptional build quality.
Optically it doesn't offer much beyond the mainstream in this class but don't
misunderstand this as something negative because moderate fix-focal length tele lenses
tend to be great performers. The center resolution is very fine to great throughout the
tested aperture range whereas the borders leave a little to be desired at f/1.8.
Stopping down resolves the border weakness and the quality is extremely high and even
between f/4 and f/8. Distortions and CAs are basically non-existent and vignetting is
pretty well controlled. In extreme contrast situations you can push the lens into purple
fringing (color blooming) problems at large aperture settings but stopping down a little
usually helps in such situations. A very positive aspect
of the lens is its bokeh (out-of-focus blur). It is very smooth and buttery making the
lens an obvious choice for portrait photography.
The biggest "problem" is not performance but the price tag. At around 750-800€/US$
the lens is about twice as expensive as competing products on the other side of the
fence (namely the Canon EF 85mm f/1.8 USM, Nikkor AF 85mm f/1.8D). Even regarding its
lovely build quality and compact design this is stretching things a little in my opinion.
Obviously Pentax came to the same conclusion - the successor, the SMC-DA 70mm f/2.4 Limited,
is quite a bit more affordable (although also one stop slower).
