Pentax HD Pentax-FA 43mm f/1.9 Limited (Silver) Review

The Pentax HD FA 43mm f/1.9 Limited is a premium pancake prime for Pentax K-mount full-frame shooters. Part of the storied Limited series, it pairs a compact, lightweight design with a classic focal length that sits between standard 35mm and 50mm primes, making it a natural fit for street photography, walkaround shooting, and everyday candids. The f/1.9 aperture offers solid low-light capability and subject separation without the bulk of faster glass.

Build quality is a hallmark here. The lens features Pentax's HD multi-layer coating for improved contrast and reduced flare, plus a Super Protect coating on the front element to resist fingerprints, moisture, and dust. The 8-blade diaphragm promises smooth bokeh, and the all-metal construction in silver gives it a refined, retro aesthetic that pairs nicely with Pentax's own heritage bodies. The pancake form factor keeps the package pocketable, though the 49mm filter thread is a less common size. At $617, it's priced at the upper end for a mid-speed prime, reflecting its Limited pedigree and specialty appeal within the Pentax ecosystem.
