Summary: I would like it better but for some reason the Auto Focus sometimes hangs up and the camera will not take a picture. Could be something I am doing wrong I don't know. I do know I don't have this problem with anymore of my other lenses.
Summary: This 18-135mm lens is nice enough, but seems overpriced for what it is. It works perfectly on every Nikon DSLR: D1, D1X, D1H, D2X, D2Xs, D2H/s, D50, D70, D70s, D80, D100 and D200. It's sharp and agile, but I suggest saving your money for the spectacular Nikon 18-200mm VR (Vibration Reduction) which you know you really want. VR is important at longer focal lengths like 135mm. See Why VR Matters for examples.
Summary: I bought this lens in a hurry as my wife accidentally broke my 18-105mm with VR. My caution to anyone looking at this lens is to be sure you have a steady hand as you will see a difference in the clarity of your pictures. The reason I gave it 4 stars is because there is noticable dust inside the lens on both ends. Unfortunately, you can see speckles in some of the images depending on the background and exposure.
Summary: I picked up a used 18-135 in July 2013 for a good price for the D300. I was using the 18-70 and it's a sweet lens, but I wanted the extra telephoto focal length of the 18-135. Yes it's known for pincushion distortion from 28-70mm range. It's worse than the 18-70 but usually not a problem if you're not shooting architecture. It has vignetting at the extreme ends worse than most zooms, but it's not THAT bad.
Summary: Years ago when I first got serious about SLR Photography I was steered to the 18-135mm zoom and I used it quite extensively. I was using a different brand of camera (Minolta) but the facility of this particular lens combination was always perfect. I have been a photographer over 60 years and have learned to be particular about my equipment.
Summary: I've been using this lens for about 10 months. I use it on my D60. I mostly use primes because they are so much faster (better for low light) and they are far sharper than any zoom that I can afford. So for any camera I own, I usually have one zoom that will do the job when no primes can. This lens fits that role nicely. This lens has what many negative reviewers say: Pincushion distortion at the extreme wide end and vigneting at the extreme tele end.
