Pentax's acclaimed 100mm macro prime, a sharp and affordable choice for K-mount shooters.
The Pentax SMC FA 100mm f/2.8 Macro is a true 1:1 macro prime for the Pentax K-mount, originally launched around 1991. With its 100mm focal length providing comfortable working distance and sharp optics throughout the range, it has been a favourite of Pentax macro photographers for decades.
Optical quality is excellent with outstanding sharpness at the focus plane and good performance as a portrait lens at f/2.8. SMC multi-coating reduces flare and ghosting effectively. Build is solid with a metal barrel and smooth focus ring. The lens provides a full 1:1 reproduction ratio at minimum focus distance.
Pentax K mount only, 49mm filter thread. Compatible with all Pentax K-mount DSLRs. The HD D FA 100mm f/2.8 ED AW Macro is the modern successor with weather sealing and improved coatings. The original FA version remains popular for its optical quality and value.
Moderate value used. Check the AF motor operation and focus ring smoothness. Inspect the front element for scratches common on macro lenses. The 100mm working distance is practical for most macro subjects. An excellent and affordable macro option for Pentax shooters.
