Everything good can be said about this lens. It is compact and great for hiking and the outdoors. The focus ( Pulse Motor ) is very fast and completely silent...and can be used for video also. The lens has the latest Pentax Coatings.

Works perfectly with my K-50 after the firmware update. This lens is noticeably sharper than the 18-135mm kit lens and has fantastic auto focus speed, especially if not using live view.

This is the fastest focusing lens in the Pentax lineup and also the quietest. I bought this little gem on April 9th and have shot it many times. It has breathed new life into my K-3 with super fast auto focus which is very precise. Continuous AF is excellent, the tracking is quick and precise.

Bought this lens along with the K-3ii about two weeks ago. Didn't work until I did the firmware update. Had to use the autofocus micro adjustment to get decent results. Even looked into returning the entire purchase.

I bought this lens reluctantly. The reviews available indicated it might not be as good as I thought I needed, but the better choice was four times the price.Now that I have it, I know that this lens is well suited to my needs. Birds in flight were beyond my old lens because of slow auto focus.

Very happy with this lens choice. Havn't taken it off since I got it a few weeks ago. Even able to take some "Macro" type shots (from about 3 ft. away @ max zoom). My only issue so far is my RAW converter of choice dosn't cover it for corrections (yet, I assume).

I needed a long lens for a trip to Africa which I took in Feb-Mar of 2018 and my wife was sweet enough to buy me this lens for my K-5. The lens was great. It is compact when you are not using it and it is very sturdy and sharp.

This is a great lens. The best thing about this lens for me is that it works with my Pentax K-S2 that has aperture block. The camera is out of warranty so that I could not get it fixed. It works great on general landscape photos and on sunsets!

Finally, I had the opportunity to bring the lens into action, taking beautiful pictures of Old San Juan in Puerto Rico, including the San Juan Bay. I am very pleased with the lens, the colors and not very heavy. An excellent product from Pentax, as always.
