AF Nikkor 50mm f/1.8D and D40x

By: jagmohan 4670 days ago

Isnt the lense an autofocus? Does the autofocus work with D40x?


By: jagmohan 4669 days ago
Well I got the answer for this. However, the other question I have is as follows: Whenever I use it with my D40x, it asks me to lock the f to the minimum i.e. to 22. How do I use other f? Or in case of D40x it is controlled through the body?

Quite possibly, but the info must be in the instruction book?

No, the 1.8 50 mm works on an D40(X), but does not autofocus. You will have to focus manually.

Hi everybody,
The 40Dx is a new 'ultrasonic focusing only' body: it connects electrically ONLY to the AF lenses where the focusing motor is installed.
The old AF lenses depend on a motor in the camera body that links using a mechanical handle (the screw that protrudes from the camera at 7'oclock' in the lens mount); it turns, 'driving' the lens focusing 'rings'.
Pro bodies retain both methods.

Regarding f/stop: the minimum f number position is the practical Nikon for AI-S lenses to pass iris control to the body (as old as the FG100 model). New G lens models do not have the f/ ring control. Adjustment of f/ is then by body settings: example: pass on M(anual) or A(perture) and the f/ choice is by thumb or index discs.
