Pentax D FA* 22890 85mm

The Pentax D FA* 85mm f/1.4 is a heavy, weather-sealed portrait prime with stunning sharpness and gorgeous bokeh. It's the best 85mm Pentax has ever made, but the weight and middling autofocus speed hold it back. Street prices around $1,500 make it a solid value compared to mirrorless rivals. Only buy it if you're committed to the K-mount system and need the ultimate portrait lens.

Sharpness is where this lens earns its Star-series badge. The optical score lands in the 74th percentile, which translates to well above average performance. At f/1.4, the center is bitingly sharp, and the corners catch up nicely by f/2.8. The three Super ED elements do heavy lifting against chromatic aberration, so you won't see much purple fringing even in high-contrast backlit scenes. It's the kind of clarity that makes you want to pixel-peep, and you'll rarely be disappointed.

The autofocus is a mixed bag. The ring-type SDM motor is quiet and accurate, which is great for stills and even video work. But it's not blazing fast. Our data puts it right in the middle of the pack at the 55th percentile. For portraiture, it's perfectly adequate. You're not tracking a cheetah with an 85mm lens. But if you're coming from a modern mirrorless system with linear motors, the focus speed will feel a generation behind. It's reliable, not revolutionary.

The obvious competitors aren't really direct ones. The Sigma 16-300mm and Tamron 18-300mm are superzooms, totally different beasts designed for convenience, not optical perfection. They'll give you versatility at the cost of image quality and aperture speed. The Canon RF 28-70mm f/2.8 is a fantastic standard zoom, but it's two stops slower and can't touch the subject isolation this Pentax delivers. If you need one lens to do everything, look at those zooms. If you want a dedicated portrait lens that creates a distinct look, the Pentax is in a different league.

Within the Pentax ecosystem, there's no real alternative. This is the only modern, weather-sealed 85mm f/1.4 with autofocus. You could adapt older manual focus glass, but you'd lose the SDM and the modern coatings. For someone shooting with a K-1 or K-3 III, this lens is the endgame for portrait work. The Panasonic S-R28200 and Nikon 16-85mm are also zooms that prioritize range over speed, so they're not really in the same conversation. This is a specialist's tool.

Pricing on this lens is all over the map. We're seeing a spread from $1,499 to an absurd $331,580 across vendors, which tells you some sellers are just throwing numbers at the wall. The real street price hovers around that $1,500 to $2,000 mark, and at that level, it's a serious investment. For a Pentax shooter, there's nothing else like it in the system. You're paying for the best 85mm Pentax has ever made, and the image quality backs it up.

Compared to the Canon RF 85mm f/1.2 or the Nikon Z 85mm f/1.2, the Pentax is actually a bargain. Those lenses push well past $2,500. But they also offer faster, near-silent AF and are designed for modern mirrorless mounts. You're trading cutting-edge speed for optical character and that legendary Pentax build. If you find it closer to $1,500, it's a solid deal. At $2,000, you really need to love the Pentax ecosystem.

The Pentax D FA* 85mm f/1.4 is the kind of lens that reminds you why people stick with a system. It's a statement piece, a big, heavy chunk of glass and metal that says Pentax is still serious about top-tier optics. This is the Star-series lens for portrait shooters and anyone who needs a short telephoto with a razor-thin depth of field. It's built for the K-1 full-frame bodies but works just as well on APS-C DSLRs like the K-3 III, where it becomes a tight 127mm equivalent.

What you're getting here is a classic portrait prime with a modern twist. The f/1.4 aperture isn't just for low light, it's a creative tool for melting backgrounds away. Pentax packed this thing with three Super ED elements and an aspherical element to keep things sharp and clean, even wide open. Add in the HD and Super Protect coatings, and you've got a lens that fights flare and repels water and dust. It's an all-weather workhorse that doesn't need to hide when the conditions get rough.

But let's be real about the elephant in the room. This lens weighs 1250 grams, which is nearly three pounds. It's heavier than most 85mm f/1.4 options from other brands, and you'll feel it after a long shoot. The build quality is solid, but our database puts it in the 19th percentile for its category, which is a head-scratcher until you realize that weight and bulk count against it. If you're looking for a lightweight travel companion, this isn't it. If you want images that make people stop and stare, keep reading.

Travel and street photographers should look elsewhere. At 1250 grams with an 82mm filter thread, this lens is a commitment to carry. Our data shows travel is its weakest area, scoring just 32.9 out of 100. If you want a short telephoto for your Pentax that won't weigh down your bag, consider the older FA 77mm f/1.8 Limited. It's much smaller, lighter, and still delivers beautiful rendering, though you lose weather sealing and modern coatings.

Video shooters who rely on autofocus should also think twice. The SDM motor is quiet but not snappy, and the lack of stabilization means you'll need a tripod or a camera with IBIS to get steady footage. If video is your primary focus, a modern mirrorless system with a native 85mm will serve you better. This lens is for stills photographers who prioritize image character over speed and convenience.

If you're a Pentax portrait photographer, this is your lens. The combination of sharpness, bokeh, and weather sealing is unmatched in the K-mount lineup. It's the kind of glass that makes you want to book more shoots just to use it. The images have a three-dimensional pop that's hard to quantify but easy to see. You'll put up with the weight because the results are that good.

For everyone else, think carefully. If you shoot events or weddings where you're on your feet for hours, the weight will wear you down. If you need fast, silent autofocus for video, the SDM motor might frustrate you. And if you're not already invested in Pentax DSLRs, there's no reason to buy into the system just for this lens. It's a masterpiece for a specific audience, and that audience knows exactly who they are.
