Product Overview
Pentax smc Pentax-FA645 35mm F3.5 AL [IF] is an ultra wide-angle prime lens for the Pentax 645 KAF2 bayonet. It covers the 645 medium format image circle. Introduced by Pentax in 2015, it has 10 elements in 7 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).
As an ultra wide-angle prime lens that happens to have relatively small maximum aperture, it is best suited for landscape photography. Even though the lens is not stabilized, at this focal range it does not usually matter. In fact, some may be able to get cleaner corners without image stabilization.
