Pentax Pentax SMC DA* 60-250mm f/4 ED IF SDM Telephoto Review

The Pentax DA* 60-250mm f/4 is the go-to telephoto zoom for serious Pentax DSLR users. Its killer feature is 99th percentile autofocus speed, making it great for wildlife and sports. It's weather-sealed and has a constant f/4 aperture, but it's heavy and its optical scores are just average. At $965, it's expensive but fills a critical gap in the Pentax lineup.

Let's talk about the Pentax DA* 60-250mm f/4. This isn't a new lens, but in the world of Pentax DSLRs, it's something of a legend. It's a constant f/4 telephoto zoom that gives you a 90-375mm equivalent reach on an APS-C body, which is basically the classic 'wildlife and sports' range in a single package. For Pentax shooters, that's a big deal because your options for long, fast glass are pretty limited.

This lens is built for the Pentax faithful who need reach and reliability more than they need the absolute latest optical formulas. It's weather-sealed (Pentax calls it 'All Weather,' not just 'Weather Resistant'), it has in-lens stabilization, and it uses a silent SDM motor for autofocus. Our data shows it scores a 77.7 out of 100 for wildlife and sports, which tells you exactly where its heart is.

What makes it interesting is the contradiction. Its autofocus performance lands in the 99th percentile, which is wild for a lens this old. But its optical score is down in the 36th percentile. That tells a story: this lens is about getting the shot in tough conditions, not necessarily about winning pixel-peeping contests on a test chart. It's a workhorse, not a show pony.

The performance story here is all about the autofocus and stabilization. A 99th percentile AF score means this thing locks on fast and reliably, even on moving subjects. That's the single biggest reason it's so highly rated for wildlife and sports. The in-body stabilization in Pentax cameras is already great, but pairing it with the lens's own stabilization system gives you a real advantage for handheld shooting at long focal lengths. You can shoot at slower shutter speeds and still get sharp shots, which is crucial when light starts to fade.

Now, about that 36th percentile optical score. It's not that the lens is soft. Far from it. Customer reviews consistently praise its sharpness, especially stopped down to f/5.6 or f/8. The lower score reflects modern expectations for edge-to-edge sharpness wide open and controlling chromatic aberration. For real-world use, especially when you're cropping in on a distant animal or athlete, the center sharpness is more than enough. The performance trade-off is clear: you're trading some ultimate optical perfection for incredible focus speed and stability in a sealed package.

At around $965, the value proposition is very specific. You're not paying for cutting-edge optics. You're paying for a unique combination of reach, a constant f/4 aperture, weather sealing, and that phenomenal autofocus in the Pentax ecosystem. For a Pentax shooter looking for a serious telephoto zoom, there are shockingly few alternatives that tick all those boxes. Compared to building a kit with multiple primes, this one lens does a lot.

The price feels high when you look at the optical score, but it makes more sense when you consider the feature set. In other systems, a weather-sealed 70-200mm f/4 or 100-400mm lens often costs more. For the dedicated Pentax user, it's arguably the only game in town for this specific job, which justifies the cost even if the specs sheet looks dated.

If you're cross-shopping outside the Pentax world, the obvious competitors are lenses like the Canon RF 100-400mm f/5.6-8 or the Sony FE 70-300mm f/4.5-5.6. Those are lighter, often sharper optically, and sometimes cheaper. But they're not constant f/4, and they don't have the same level of integration with their respective systems' stabilization. The trade-off is system loyalty versus absolute optical performance and weight.

Within the Pentax universe, the main competition is the older, slower variable-aperture zooms or using a teleconverter with a shorter lens. Neither option gives you the same consistent aperture and autofocus performance. The DA* 60-250mm sits in a lonely but important niche. The other 'competitors' our data shows, like the Viltrox 35mm or Tamron 17-70mm, aren't really competitors at all—they're completely different lenses for different purposes. This highlights the lens's unique position: it has no direct rival for Pentax users who need what it offers.

Skip this lens if you're a portrait photographer. Our data gives it a 39/100 for portraits, and for good reason. The 2.5-meter minimum focus distance means you can't get close for headshots, and the f/4 aperture won't give you the creamy, blurred backgrounds (bokeh) that faster primes will. Portrait shooters should look at the Pentax 77mm f/1.8 Limited or the 50mm f/1.4 instead.

Also, if you're new to photography or want a lightweight, walk-around telephoto, this isn't it. At over 2 pounds, it's a commitment. And if you're using a Pentax full-frame camera, this APS-C lens doesn't make sense—you'd be wasting most of your sensor. Finally, if optical perfection is your top priority and you don't need weather sealing, you might find newer, third-party lenses for other systems that offer sharper results for less money, but you'd have to leave the Pentax ecosystem to get them.

For the Pentax APS-C shooter who photographs wildlife, sports, or needs a reliable, sealed telephoto for outdoor adventures, this lens is an easy recommendation. The autofocus and stabilization are superb, and the weather sealing lets you shoot when others pack up. It's a tool that gets the job done in the field, and that's what matters most for those use cases.

However, if you're a portrait photographer, a pixel-peeper who demands flawless optical performance wide open, or someone who values a lightweight kit, you should look elsewhere. Our data gives it a dismal 39/100 for portraits, thanks to the longer minimum focus distance and slower aperture. For those users, a fast prime like the Pentax 77mm Limited would be a far better choice. This lens knows what it is, and it excels at that one thing.
