Nikon D3100 and Non-cpu lens?

Guest

I've noticed that when I use non-cpu lens on my Nikon D3100, the exif data shows up as 0.0 mm".
I'm using a Promaster 80-200mm 4.5. I was wondering if there was anyway to display or change the exif data so that it displays the correct aperture and focal length?

Sorry if it's a noob question, still learning my camera!

Nope, being non-CPU means that information is not collected.

Without a CPU, the body just can't see the lens, this is also why your meter won't work.

The D7xxx series get around this, but the D3xxx and D5xxx can't.

The CPU in the lens is what collects the information from the lens and sends it to your camera which is then written to your image file.

Some cameras have a "non-CPU" feature in the menu where you can enter the data of each non-CPU lens you use.

Look on pages 167 to 169 of your user manual for a list of compatible lenses for your D3100
