Auto Focus Nikkor AI-S: 24mm f/2.8, 28mm f/2.8, 35mm f/2.0, 50mm f/1.4, 60mm f/2.8 Micro, 85mm f/1.8, 80-200mm f/2.8

Auto Focus Nikkor AF-S/G and AF-S/G DX: 10.2mm f/2.8, 12-24mm f/4.0, 17-55mm f/2.8, 18-70mm f/3.5, 18-200mm f/3.5, 24-85mm f/3.5, 28-70mm f/2.8

I use the 17-55mm f/2.8, 12-24mm f/4.0, 28-70mm f/2.8, 85mm f/1.8, and 28mm f/3.5 PC the most.

The D40 [just now replacing a D50] with the 18-70 or 18-200 make up my small travel kit when I am not going to be doing any critical work.

The 18-200 is optically superior to the 18-135 so I personally would put up with the extra length of the 18-200. If you don't need a long telephoto then the 18-70 is also superior to the 18-135 and smaller still.

The 18-135 is still a very good lens but the others are better especially at the 18mm end. In fact, the primary drawback to the 18-135 is that it is not as robust in terms of construction as some of the other 'consumer' grade Nikkors.

90% of the population would be just fine with the 18-135. Decide for yourself how critical your work needs to be.
