Explain how you are using this lens. Unless you have done a Leitax or similar conversion, the rules for an adapted Nikon F lens are the same as for an adapted M42 lens.

When using a lens without the "A" contacts on the mount, all auto exposure modes (P, Av, Tv, Sv, and TAv) fail over to Av mode. Pressing the green button will not do anything in Av mode. If you want to control the shutter speed, you must be in M mode. The green button in M mode will match shutter speed to the metered light coming through the lens.

i understand that I must "short the contacts" using aluminium foil in order to use cif. am I correct?
Only if the adapter or lens flange is made of a non-conductive material.
Originally posted by zzzxtreme question three:
can I use continuous shooting with cif? if yes, during the continuous shooting, is the exposure fixed? I mean let's say I compose+pressing green button, then activate continuous cif, and suddenly the subject gets dark. since it is not possible to press green button during a continuous shooting, that behaviour is expected I assume
The answer is yes, as long as the PDAF system does not register loss of focus. Exposure is fixed in M mode, but will vary in Av mode.
