Works for me as a basic lens on my Pentax Full Frame K1 camera. Easy to use and totally awesome picture quality. Quality solidly built lens. This is not cheap plastic construction. Fine optics for a lens in this price point.

This is a very good lens for traveling. The zoom range allows for both wide-angle panoramas and close-ups on the go. At f8 - f11 apertures the sharpness is more than decent so it's basically a day lens, although on a tripod by night or when using a ND filter it also delivers.

This is a very good walk around all day lens. I use it constantly and the quality is good.

I bought this lens with the K-1 and have been very happy with the picture quality. Up until recently, kit lenses were of lower quality and people viewed them as good entry level purchases.

The zoom hangs up. After 4 months of very light use, something inside came loose and it stops it from turning.

This is a great lens. This is actually my 2nd lens my first one fell over on the tripod and hit head on. It still worked, the the zoom ring was a little stiff to rotate. It's nice and clear and a great all around lens.

Excellent walk-around lens for K1. Color rendition is great, small size, light weight and works well with my Nisi filter system. It just doesn't make sense to me people spends premium price on similar items on other brands. Go Pentax !

Superb walk around lens. I use it on a Pentax K1 and edge to edge sharpness at various focal lengths is good to excellent, although not quite in the class of prime lenses. Highly recommended, especially for travel photography.

Haven't used it much, but looking forward to some great shots of race cars at night!

Using this with Pentax K-1. There is plenty of reviews around of this lense, check them. My personal opinion: This is the best all-around and walk-around zoom choice for K-1 at this price. It is sharp "enough" from open to f16. The IQ is very good, the lens focuses fast, accurately and silently.
