Unlike the later F90x/SB-26 combination, the F4/SB-24 is smart enough to automatically switch from balanced fill flash to full TTL flash when ambient light is insufficient. Still, when combined with the concurrent SB-24 or newer dedicated flash units, the Nikon F4, without D technology, still has great flash performance in its own right.
AF-D technology, which only appears on future generations of Nikon SLRs, transmits distance information from AF-D lenses and permits better flash and fill-flash performance. The F4 does not yet support AF-D technology.
Nikon f90x batterys manual#
As indicated above, the F4’s program and Tv modes cannot be used with manual focus Nikkor Ai lenses (you need a Nikon FA for that). The major disadvantages of the F4 compared with its predecessor F3HP are almost 50% greater weight, and increased size and decreased battery life due to the motor drive. When I bought my F4, it was only available in a package with the larger MB-21, which I immediately replaced with the MB-20 to cut down on weight. Unfortunately, the Nikon F4 was not designed to work with light-weight lithium AA batteries, which are not recommended by Nikon. The MB-21 grip uses 6 x AA alkaline batteries compared with 4 batteries in the MB-20 and provides slightly faster motor drive. The F4 system includes the F4s, which is the basic F4 body with the enhanced MB-21 battery grip instead of the basic MB-20 grip. Finally, the F4 system has an amazingly broad system of accessories of all types. It also has a built-in diopter control in the viewfinder. Significantly, for those with a collection of manual focus Nikon lenses, the F4 provides matrix metering, but not Program or Tv modes, with Ai manual focus lenses. All controls are presented as traditional knobs or switches, although they control sophisticated electronic functions, internally. In fact, there are no external digital readouts or multi-function dials on this camera. Although the camera is fully electronic, it maintains the façade of mechanical camera controls. The F4 has autofocus, motorized film advance, program and shutter priority exposure modes (in addition to aperture priority and manual), multi-segment (Matrix) exposure metering, and advanced fill-flash capabilities.
Nikon f90x batterys upgrade#
The Nikon F4, technologically speaking, is a major upgrade from the F3HP.
