Pentax D FA 90mm f/2.8 ED AW SR 90mm

The Pentax D FA 90mm f/2.8 is a portrait specialist with some of the creamiest bokeh we've tested. Built-in stabilization and weather sealing are great, but autofocus is just okay and it's heavy. Buy it for the look, not for all-around performance.

Sharpness is solid here, landing right around average for its class in our optical testing, but the real star is the bokeh. That f/2.8 aperture combined with a 9-blade diaphragm puts it in the top 15% of lenses we've tested for rendering out-of-focus areas, and it shows. Portraits have a creamy, three-dimensional pop that's hard to fault. The built-in Shake Reduction is a genuine lifesaver on a medium format body, keeping things crisp when you're shooting handheld. The weak spot is the autofocus, it's functional but not snappy, sitting at the 55th percentile. For slow, deliberate portrait sessions it's fine, but don't expect it to track anything moving quickly.

Stacked against the competition, the Pentax is a specialist in a sea of generalists. A lens like the Sony 70-200mm f/2.8 GM II is more versatile, faster to focus, and optically superior, but it doesn't give you that medium format depth of field. The Canon RF 28-70mm f/2.8 is a fantastic standard zoom, but it can't touch the Pentax for bokeh quality. Even compared to something like the Tamron 17-70mm f/2.8 for APS-C, you're trading all-around usefulness for a singular, beautiful portrait look. The Pentax isn't trying to do everything, it's trying to do one thing exceptionally well, and for the right shooter, that's enough.

At $4,497, this lens is a serious investment. You're paying for the medium format look, the best-in-class bokeh, and the rugged, weather-sealed build. If you're a working pro who bills for portrait sessions, the image quality can justify the cost. But if you're a hobbyist or someone who shoots a bit of everything, the value proposition gets shaky. The optical sharpness isn't chart-topping, and you can find faster, more versatile glass on other systems for less money. You really have to want that specific Pentax 645 rendering to make the math work.

The Pentax D FA 90mm f/2.8 ED AW SR is a medium format portrait lens that knows exactly what it wants to be. It's built for the 645 system, giving you a roughly 71mm equivalent field of view with a bright f/2.8 aperture that melts backgrounds into butter. If you're deep in the Pentax medium format ecosystem and need a dedicated portrait or studio workhorse, this lens makes a strong case for itself.

But let's be real, this is a specialized piece of kit. It weighs over a kilo, it's not exactly versatile, and the autofocus is just middle of the pack. This isn't a lens you toss in your bag for a casual walkaround. It's a purpose-built tool for photographers who prioritize bokeh and sharpness above all else, and are willing to pay a premium for it.

If you need a fast, flexible telephoto for events or wildlife, look elsewhere. The autofocus isn't snappy enough for action, and the fixed 90mm focal length will leave you frustrated when you can't zoom. Hybrid shooters who split time between photo and video should also steer clear, the video scores are mediocre and the focus breathing will likely be an issue.

This is a lens for the dedicated Pentax 645 portrait photographer who values bokeh and build over speed and versatility. If you live in the studio or shoot environmental portraits in rough weather, you'll love the images this thing produces. It's a niche tool, but within that niche, it's a standout.
