This is a fine piece of glass, sharp enough to rival primes at 300mm. Good choice for aircraft, birds, and other odds and ends in flight. Some birders will want a bit more reach but 300mm on a APS-C camera works rather well in many cases.

Very good sharpness and IQ at f/4 and only improves from there. Easy to handle given its heft.

Size and weight are considerable but those attributes are very subjective. I'm certainly not carrying it around on my neck all day but I am investigating the BlackRapid system. That may be fine way to handle two bodies - one with a whacking great telezoom.

Please note that the Pentax version does NOT support HSM, in spite of the Amazon title and listing.

I submitted to Amazon a request for correction that included the URL for the Sigma Web site page that noted the Pentax exception for HSM. Amazon rejected my correction, indicating that Sigma's Web site did not substantiate my submission.

You all can check Sigma's site for yourself. No point in arguing. Perhaps Amazon has a model no other retailer does? Ummmm. You decide.

Now I understand that I must research Amazon's product descriptions for myself. I've no interest in asking my bank to reverse credit card charges.

The lens, though, is fine. The fifth star is removed owing to the lack of HSM.

I use it with a 1.4X teleconverter and it still give me a very good image quality
