Would you be able to give me the exact name & model of the lenses that you are using?
Do they happen to be "K" mount or are they "M42" etc?
All the old lenses that I have are "M42" aka "Screw mount" and when I attach them to the camera body I have to select the desired focal length, since the camera can not "read" that info from the lens.
So If I'm using a 55mm lens I would have to select 55mm for the focal length when it prompts me. If your using a zoom, you would select the longer focal length. So take 70-200mm, you would use the 200mm.
The way you should mount it should be:
- Turn the mode dial to M (Manual mode)
- Turn the camera off
- Take off the kit lens, or what ever lens your using
- Mount up the old lens
- Turn the camera on and within a few seconds on the back lcd screen, you should be prompted to set the desired focal length.
That should at least get the camera working with the lens.
Although, if my memory serves me right, there might have been a menu setting that needs to be tweaked. So I'll look into that for you.
