HD PENTAX-DA 55-300mm F4.5-6.3 ED PLM WR RE chosen as the best budget telephoto-zoom lens in 2018 by Digital Camera World!
Clever design and a quality build
“For a budget lens, the build quality of this Pentax lens feels particularly good, and it’s the only lens in the whole group to feature weather seals. It’s big on zoom range, equating to 82.5-450mm on a Pentax APS-C-format body in 35mm terms, yet its build is physically small when stowed away; this is thanks to a clever retractable design that enables the lens to collapse down to just 89mm in length. It also features a stepping motor autofocus system, the near-silence of which is an improvement over some of Pentax’s notably noisy lenses. There’s no optical image stabilisation, with the lens instead relying on in-camera stabilisation, which is present in all modern Pentax DSLRs. The autofocus system is quick and highly accurate, and testing the lens on a K-70 body, we found stabilisation to work well, with a four-stop effectiveness. Despite having the outright biggest zoom range of any lens in the test group, image quality is excellent.”
