Special thanks to Rüdiger Neumann for providing this lens!
The Pentax SMC FA 77mm f/1.8 Limited is another representative of Pentax'
prestigious Limited lens lineup. The production of the lens seems
to fade out in favor of the new SMC-DA 70mm f/2.4 Limited but you should
still be able to find new ones for around 800€/US$. It is not a budget
item obviously - "normal" AF 85mm f/1.8 lenses sell for a lot less these days.
Typical for all FA lenses it supports the full 35mm format so it can be
used both on film and digital SLRs. On the Pentax K10D its field-of-view
is equivalent to about 120mm (full format).
The build quality of the lens is superb with all parts made of metal.
The small focus ring operates very smooth and slightly damped. Typical
for FA-type lenses there's a dedicated aperture ring on the lens.
The FA 77mm f/1.8 extends a little when focusing towards close distances.
A nice feature is the built-in telescope-style lens hood (not shown below).
The lens is/was available in a silver- and black-colored variant.
The FA 77mm f/1.8 has no internal AF motor and relies on a slotted drive screw operated
by the camera. As a result AF operation will generate a moderate degree of noise.
The AF speed is very fast on the K10D.
