Find out what 14 readers thought of the Pentax 50mm f/1.4 SMC P-FA in our review.
The Pentax smc FA 50mm F1.4 is something of an anomaly in the company's current lens lineup, as the last of their film-era primes featuring plastic construction and an aperture ring. This actually reflects the fact that Pentax are probably the leading proponents of modern-design fixed-focal length lenses, with their range of compact 'pancake' lenses and 'Limited' series high quality primes being the envy of users of other systems. Indeed we can probably presume that the 50mm F1.4 will itself be superseded by the recently-announced Pentax-DA* 55mm F1.4 SDM lens, but in the meantime it stands as the most obvious option for users seeking a fast prime for low light and portrait work.
The Pentax SMC FA 50mm F1.4 lens struggles to keep up with modern high-resolution cameras.
