Hi Guys,
I've recently bought a Nikon D80 with a 18-135 lens.
I've added the well praised Prime 50mm AF 1.8D lens.
With the D80 do I manually select the 1.8-22 settings?
What is the aperture lock?
I adjust the 0.45 to Infinity as required?
What do I need to do?
sorry, basic stuff but poor instructions with the lens for a novice.
