Reviewer Consensus

Good

The Pentax HD Pentax-D FA Macro 100mm f/2.8 ED AW delivers impressive sharpness and durable weather resistance, making it the premier macro choice for Pentax shooters. Its dated mechanical design relies on a telescoping barrel and noisy screw-driven autofocus that lacks modern internal motor refinements.

  • PetaPixel 7/10

    While it may not be perfect by modern and mirrorless standards, for Pentax users, this is the best macro option you can get.

  • PCMag

    The Pentax HD D FA Macro 100mm F2.8 ED AW lens benefits from a refreshed optical formula that works better with high-pixel digital cameras, but Pentax didn't bother to make other changes to an outdated design.

  • Pentax Forums 8.8/10

    Screw-drive AF is a disappointment, and prevents us from seeing this lens as a true modern offering, but there is no arguing that its improvements are real and notable. It is another good product from Pentax, worthy of consideration.
