Pentax HD FA 150-450mm f/4.5-5.6 ED DC AW Review

This 3x super-telephoto zoom lens covers an interesting zoom range which fills a long established gap in the Pentax line-up, as telephoto zoom lenses have been thin on the ground, with many Pentax camera owners relying on offering from third-party lens manufacturers. Another point of interest is the fact this lens sports an image circle large enough to cover a full frame sensor and provides a focal length roughly equivalent to a 230mm - 690mm range when used with Pentax APS-C DSLRs. It's interesting that Pentax/Ricoh have chosen to release this lens with full frame coverage, as all of their current DSLRs are fitted with APS-C size sensors. This means there may be truth in the announcements that a full frame Pentax DSLR will be available by the end of this year. It sports silent focusing, weather sealing and HD anti-reflective lens coatings and a price at launch of around £2000. In this review, we'll take a look at how this lens performs on an APS-C Pentax DSLR, it will be interesting to see how the lens performs in the future on a full frame camera, when one is finally released.
