Customer Question
I recently purchased a Nikon...
I recently purchased a Nikon AF Nikkor 70-301:4-5.6 G lens for my D3300 DSLR. The first two days, I hadno trouble manually setting the f-stop in ALL modes of the camera. It took marvelous pictures in manual, effects, auto, portrait, every single mode as I was able to set f-stop and ISO value or the autoatic mode did it for me flawlessly. Today, when I attached the lense, it says "lens not attached in every mode exept manual and the apertur symbol shows fuly shut and won't udge if you try to set the f-stop. This isn't going to ork for me; what happened and what do I do?

it is.

One option that may work is to clean the contacts on both the camera body and lens with alcohol and a cotton swab. Try this and let me know what happens.

I cleaned all contacts and metal prts with alcohol and cotton swabs. no luck at first; trying again now.....
Camera and Video Technician: Rick, Camera and Video Technician replied 2 years ago

Do you have another lens to try on the body to see if you get the same result? This will narrow down the malfunction to either the 70-300 lens or the camera body itself.

I have another lens and it does not exhibit the same problem.
Camera and Video Technician: Rick, Camera and Video Technician replied 2 years ago

At least you know the problem is in te lens and not the camera body. These lenses are subject to flex cable failures which will need to be installed by a technician. On the other hand, it may just be a loose connection to the circuit board but it will need to be disassembled to troubleshoot and repair. This really isn’t a user serviceable problem and should be repaired by a qualified technician. You may want to check locally for a camera repair shop in your area, or, ifyou need assistance finding a shop, please let me know and I'll locate one for you.
