Thanks everyone. I did some more tests last night (albeit brief). Comparing the 18-150 to at the long end to my 55-200 was an open and shut case. The 18-150 is pretty lousy by comparison - though not as bad as the first copy I had. Even things that are supposedly in the plane of focus are blurred when I look critically, and there's noticeable chromatic aberration. I've compared these two before though, and this was no surprise.

What shocked me though is when I compared the short end to my 18-55. The 18-150 was better! And by quite a margin. I wasn't expecting that at all. I don't think I'd run that comparison before.

If the 18-150 behaved like that through the range, I'd be very happy. However mine seem to fall apart around about 70mm, and over 100mm it's useless for critical shots, or where any cropping is needed. I am now wondering if it's worth buying a third copy (third time lucky?). I'd be grateful if someone can post an example of their 18-150 at or near 150mm with no post processing (by which I mean no contrast or chromatic distortion correction). That should help me judge if mine's a lemon.

If your 18-150 isn't very good at the long end, then definitely look for a better copy.
