Digital Cameras Photo Reviews of Pentax 21870 DA 50-200mm F/4-5.6 AL Weather Resistant Lens

Customer Review: Great universal Pentax tele-lense
Summary: 5 Stars

Knowing that I needed an automatic focusing mid-range telephoto lens to augment my Tamron 55-210mm lens from my film based Pentax cameras, I looked very closely at the specs for lenses on the market in this category. As I do a lot of on the water yacht portaiture, having a waterproof lens to use with my Pentax DSLR cameras was a key consideration. The Pentax 50-210 handily filled this bill, and is the #2 lens in my optical inventory.
With a fast focus response time, excellent contrast and overall sharpness across the lens range, I find that this lens approaches the performance of my Pentax 105mm prime lens, but has the flexiblity of a great zoom range, along with full coupling to the auto/focus, auto/exposure systems of Pentax cameras. The big plus of course is that it leverages the body based auto-stabilization system in my Pentax K200D, allowing me to use every Pentax lens I have in my inventor(including the 50mm 1.4f lens I acquired in the 1970's) in autostabilization mode. Try that on a Nikon or Canon.
I have not needed to trust the waterproof feature of the Pentax K system and it's lenses, but after watching review of this capability of these cameras being used in a bathroom shower on You-tube, I believe that this capability puts this lens and the associated cameras in the league of the four figure priced competition.
