Pentax smc Pentax-FA 43mm F1.9 Limited Full-Frame Lens (2021)
Product Gallery
Product Overview
Pentax HD Pentax-FA 43mm F1.9 Limited is a normal prime lens for Pentax K-mount. It covers the full-frame image circle. Introduced by Pentax in 2021, it has 7 elements in 6 groups.
Unfortunately, Pentax has opted to omit weather sealing for this lens, so owners should pay extra attention when shooting in incremental weathers. On the lens barrel, one can find a physical aperture ring. Those who wish to focus manually can have the best of both worlds (with the usual caveats).
A normal prime lens, the HD Pentax-FA 43mm F1.9 Limited has the potential to be one of the most used and ultimately versatile option in a photographer's bag. Usually the easiest to design and to QC, it is a great option for landscape and street photography. Its bright maximum aperture also helps night and portrait works. Those who like sunstars (sun bursts) will be pleased by the lens' even-numbered aperture count, though conversely those who find sunstars distracting may have the opposite feeling.
