I'm asking this for a friend, who, has a Nikon D70. I use Canon so know nothing about Nikon.

He knows very little about the camera etc and cannot get his 70-300mm to auto-focus until f32. It will not auto-focus at any aperture bigger than f32.

Not sure which lens it is exactly but it's a silver 70-300mm with macro and pretty new....kit type lens.
 
If it's got a macro feature it's not a Nikon lens, also I've never heard of a lens that will only autofocus when there is only a tiny amount of light through - it's usually the other way round. Normally the more light getting to the camera the easier it will be for the autofocus to work....

The lens has to have the aperture ring set and locked at its smallest aperture, in this case f32, then the aperture is set on the camera body.
 
If it's this lens, then that could be correct. You have to leave it at f32 and change the aperture with the front scroll wheel on the camera, otherwise you will get an error message on the top LCD (I think).

It is a Nikon lens in a Nikon box...with a Macro feature.

Sounds good. How do you lock the ring

Iirc it does give an error. Not sure if it's that particular lens.

He told me today that he has bought two more lenses, don't know which ones, and they also act the same way.

I'm ringing him later so will know more then.

Thank's.....
 
Thinking about it....it was'nt the 70-300mm that I was playing with:) it was a smaller lens but it did have a Macro/Micro feature.

Both lenses acted the same way though.
 
Just rang him and all is working fine now. Setting the aperture ring and locking it seemed to do the trick.

Had to laugh though as he's had the body 4 years and has never used the scroll wheel on the front and did'nt really know it was there.:)

The lens I was on about was this one so I got it all wrong...was a while ago though. It does have a Macro feature.

He's just bought the 80-400mm and a sigma 150mm Macro.

Thank's all......

Glad to help Mick, in future tell him to read the manual :D
 
I was going to suggest cleaning the contacts. Ive never had to on my own camera but a friend recently had his camera stop auto-focusing. We cleaned the contacts gently and hey presto all working again!
