A very
nice features of Nikon F4 is the interchangeable battery packs. We call it
battery pack instead of motor drive because there are no motor inside other than
compartment for batteries.

introduce to the international market (except USA) in year 1991. This is the

MB-23 provides a firing rate of 5.7 fps and vertical firing button. There is a
switch on the MB-23 to choose between Alkaline and NiCd batteries. The strength

Note: Many photographers use AA
lithium batteries in their F4. This is not recommended by Nikon because the
original voltage of lithium batteries when new are quite high and their tendency
toward voltage fluctuations (more than 1.5 V). NiMh batteries are also not
recommend by the factory although many have no problem using them. It is
believed that using either lithium or NiMh batteries can greatly shorten the
life of the camera, and damage can occur in long run.
