Sigma 50-500mm "Bigma" Review
A unique lens offering amazing sharpness
By PF Staff in Review Announcements on Mar 18, 2011
We're happy to unveil our review of the new Sigma 50-500mm F4.5-6.3 OS HSM lens!
Using it in the field was certainly a new experience for us, as no other lens for Pentax is as compact while offering such a long zoom range. In fact, it's got 200mm more reach than the longest telephoto zoom from Pentax, the 55-300mm. We found it to be razor-sharp at all apertures and focal lengths, although its bokeh and distortion control was not as commendable. Check our the review for more details!
