This lens works very nicely when shooting wildlife with a Pentax K-50. I am amazed how well very tightly cropped photos hold up with this combination. Autofocus is sometimes an issue in some situations for me, but I am able to switch easily to manual focus to get the shot.I normally shoot RAW+jpeg.
Was my first purchase for the K-5. Poor lens. Avoid! Avoid! Avoid! May be cheap but it's a false economy, as most of your shots will go in the bin. While contrast is ok, and CA and flare is not excessive, getting something sharp with this lens is rare to impossible, even stopped down.
WR, price, size, useful focal range
not fast, not sharp, poor bokeh
Buyers, please be aware, as per another review, 'Another Deal Site' are providing cheap kit versions of this lens and not as advertised. Where the advertised lens retails for $250, the other lens only retails at $100 (Though is only meant to come with a kit).
