At short focal lengths (below approximately 35 mm) the barrel distortion is quite noticeable

There is slight barrel distortion at 200mm

There's a little bit of barrel distortion, but it's easy to auto-correct in Lightroom or the photo editing software of your choice

As I say, you can quibble over a few items, but many of these are addressed with simple software adjustments (sharpness, barrel distortion, etc.), and so I can't say that the average photographer should worry about these too much

Yes, you can quibble about barrel distortion at certain zoom levels, can probably find some image softness at certain points, and, yes, there is a bit of lens creep once you get the lens broken in, but if what you are looking for is a single lens that lets you walk around and concentrate on learning how to compose and shoot photos, this one is hard to beat

I love this lens as it takes great close ups or long distance shots with out changing the lens.

Not as sharp as my primes (but sharpness is controlled mostly by me, not the lens)
