Summary: The lens seems fine but for some reason my Nikon D5300 "hunts" with it attached. None of my nikon lenses that do that. It doesn 't hunt when attached to my Nkon D90. Can you help me with this problem? Also, the zooming ring is fairly stiff R.
Summary: I've owned more than 50 dslr lenses over the past ten years and I've been disappointed only twice. I've never had the "bad copy" that you hear so much about. The first digital slr I ever owned was a Canon Rebel and I knew nothing when I bought it. Nothing about digital and nothing about modern lenses. I had owned many film cameras and lenses but it had been many years. So those first two lenses includeda real dud. That one was on me.
Summary: Overall this is a great walk around. I would recommend it. If you're searching for more of a wide and and more of a zoom then I'd highly recommend the Canon 15-85. That lens is 'L' quality. This lens won't give you that kind of quality but it is cheaper and it's great for the casual user. The bokeh on this lens is nice and color contrast is nice as well. I do wish it was a constant 2.8 but I knew it wasn't when I bought it so I can't complain.
Summary: Not a bad lens, not weather sealed like many Pentax k-mount lenses. Images aren't bad, and the range is pretty good, the biggest issue, is that it doesn't have internal focusing. As the lens isn't huge, it rested naturally in my palm but my pinky and ring fingers touched the manual focus ring, which moves when the lens is in auto-focus, make the motor emit a high pitch squeal. It was so annoying to me after a few days trying it out, that I returned it.
Summary: I expected this new lens to be business and tak sharp . Sadly after paying a hefty price I am left unimpressed. It looks good and well balanced feel on my K5. For a fast lens at f2.8 I did not find it any noticeably faster and had similar shutter speeds with much cheaper basic f3.5 lenses. I found myself reverting to manual focus in lower indoor lighting as the AF does not perform as good as I expected.
