Error maeesge and no auto focus

What message? if an FEE, perhaps you forgot to put the Diafragm marking to the greatest figure (22 or so) and forgot to put the lock on.
Next time, I think it could be very helpful you tell what error you see. Nobody needs to guess what you see.

I have a Nikon D80 that reads "ERR", won't take photos, but shutter still fires. I tried cleaning the contacts, and still I get the ER msg. Help?

Does your lens have a diafragm ring, A ring with numbers on it like 22 16 11 8 5.6 3.5. Set this ring to the maximum. I hope this helps.

Hello. I just bought a Pentax me super with 1.4 very cheap and in very good conditions. There's just one problem. The problem lies in the mount of the lens. I guess it's called aperture ring? When...

Take the lens to a repair facility. When you've recovered from the shock of the cost, look on Ebay for a replacement. FYI, it may be better to get an f1.7 lens instead - far far cheaper, and the f1.4 was notorious for less than optimum optics wide open. You'll only lose half a stop or so, which is negligible.

Does your lens have a diafragm ring? Set this one to the maximum, for instance 22. Maybe this will solve your problem.

The diafragm it´s closed not

I dropped the camera and got the same problem, until I read somewhere in this site that open the camera and then tapping on the ring around the lens while power on and off several times, it will work again. I did for me. I took it apart with phillips screwdriver and I used a hard rubber caulk spreader to tap it; it has some weight but will not damage the lens if its it by mistake. Try this and will be surprised. I am the 3rd person I have read that solved it doing this. Web ready Video is good in this camera. Good luck.
