When I have the Tamron 18-200mm on, the Focus Mode is MF and Area Mode is in single point I cannot change them. However, when I replace it with a Nikon 18-55mm it works.
Is that a problem with the lens?
Thank you for your reply.
It seems that the early version of that lens has the screw type autofocus that relies on the built-in AF motor in the camera body. The Nikon D3xxx and D5xxx series cameras don't have the motor. The D7xxx series and above Nikons have the motor. I'm not sure which version you have. I don't know how the lens can alter the AF area mode though.
