Question about Nikon D70s Digital Camera
I have never been able to auto focus with my Nikon DX AF-S 18-70mm lens. Is there a cure for this?
Sure there's a cure! Auto focus on the 18-70 and a D70 has a few switches and menu settings that help to set it up. The switches are on the lens (I'm going to guess this is the one you're missing) and the side of the camera body. If you only have problems with this lens and other lenses auto focus fine, this is really the only thing that could make it not focus. The switch has two settings, M/A and M. It must be in M/A in order to auto focus. Older auto focus lenses don't have this switch.
The other switches and settings would result in auto focus not working with any lens you put on.
If you have problems with other lenses, or if the 18-70 is your only lens, drop a note here and I'll go into more detail on the other settings.

My Nikkor DX 18-70mm is a great little lens, but the thin cable at the front of the lens inside bends as the lens moves in and out, and eventually cracks along the bend- affecting the power/signal to the lens motor.
This flat cable has to be replaced in a dust-free environment by an expert, because there are other tiny brittle bits in a lens that will break if you don't know what you are doing.
I know this because I initially opened mine and forced a section that simply needed a tiny twist - and ended up replacing 3 parts...

I had a similar problem with one that I bought. and come to find out, the gears internally in the lens where broken. I would return the lens, and get another one. Also when you go to buy a lens for your camera make sure that you bring the camera with you to test the zoom before you buy it.
Just FYI you also need to remember that with a smaller zoom your focus time will be slower, and it will take getting use to, unlike the larger zooms, you are trying to focus on a large area but being very detailed at the same time.
