One of the most interesting aspect in the design of Nikon F4 is its ability to adapt to various power sources. Unlike any of the previous Nikon F3 which essentially being the first Nikon professional F-class model to go all-electronic. The tiny button cell powered Nikon is easily regarded one of the most power efficient Nikon professional F ever, even with its motor drive powered design (one of Nikon F3's most appealing design is, once it is mounted with its dedicated super-power-efficient Nikon MD-4 motor drive, all power will be drawn from the drive) and it even ensure the camera still operational as it has a back-up mechanical shutter speed in case all its power fails to function and/or depleted.

A controversial issue relating to the Nikon F4's basic configuration was Nikon's decision to remove the backup mechanical shutter speed from its impressive feature lists. This has made Nikon F4 entirely depends on battery to operate - such very un-Nikon's approach was something that has made many professional users and Nikon faithful felt a little uncomfortable over such 'drastic' decision. Especially at the time of its introduction, other than a Nikon FM2(n), virtually entire Nikon line of SLR models were electronic cameras.

Realistically, to support the enormous computing power requires more than just a button cell as used by the F3. Besides, there are more operational tasks to handle as the Nikon F4 has a built-in film transport for automatic film advance and rewinding as well as complexity in the Matrix Metering - ALL take battery power to function ! However, among all the power-eating elements, the real demanding task is actually the decision to adopt a camera driven autofocus concept as opposed to camera/lens driven system used in the prototype Nikon F3AF back in 1983/4. There are four coreless motors built into the Nikon F4 camera and all sucks powers even though they are designed to be power efficient. So, the use of multiple power cells for the Nikon is inevitable and become very logical. Designed as a professional camera, probably everyone would expect a basic Nikon F4 body should be small enough to perform like a professional class SLR one would expect it to be but I think the real challenge was, it is something like merging a "MD-5" inside the Nikon F4. The highly acclaimed MD-4 for the F3 takes 8 penlight batteries, the Nikon 4 halved that number down to just four cells to power all it needs to enable it to function which eventually boils down to one fact - how many film rolls can it take ? Not many...

So, using similar concept of attaching a additional power support, the modular system concept is back - Nikon designed a series a power sources to ensure the Nikon F4 will never has its user worrying it may be lying dead - The bare basic Nikon F4 camera consists of a Battery Pack MB-20 Powered by four AA-type alkaline batteries, it also serves as the F4's grip.

Changing battery with the F4 is a fast and quick process. There is battery pack removal switch at the bottom and its design is so easy that you can actually change it with one hand. One of the advantage offers in the F4 is the choice of battery source. AA-type alkaline batteries are readily available every where. Although early indication by Nikon that AA size Lithium cells are not advisable to use with F4 but many users have actually been happy using it without any significant disastrously results. However, as a matter of guideline, I would not like to challenge such official user's guidelines issued and neither I intend to misled nor encourage such unauthorized usage. The bursting rate in continuous AF servo mode for Nikon F4 (with MB-20) is slower than using other combination(s) of Power Packs such as MB-21, MB-22 and MB-23. See bottom of this page for comparison.

NOTE: As most problems from electronic cameras are usually battery related. If your camera is inoperative (in particularly inactive for a long period of time), check the battery contacts inside the power pack as well as the camera sections for corrosive contacts. Use eraser to scrub off any possible deposits and see if it works. ALWAYS remove the batteries if you are not going to use the camera for a long period of time.

One page summary for installation of a MB-20 onto the Nikon F4, scanned from Manual (144k Jpeg)

Battery current consumption (using battery pack MB-20 with Multi-photomic finder DP-20 at room temperature (20 degrees C). Also take note: Batteries with a "+" terminal exceeding 5.5mm in diameter
CANNOT be used.

NOTE: When the battery pack MB-20 (AA-type battery x 4) is mounted, the battery can be checked by opeating the shutter pre-release timer located on the body. 1. Battery can be used when the shutter pre-release timer operates for 16 seconds. 2. If the timer does not respond when the shutter pre-release is operated, the battery is exhausted. 3. The battery can not be used when indicators do not light up and shutter release is locked. One of the main reason why Nikon resists users to use other batteries is, as it is very difficult to carry out a battery check when NiCd or Lithium batttery pack are used with the MB-20, please be reminded that both will give an incorrect display.

1. Less than 5 powersymbolB.gif when power switch is off.
2. Approx. 10 powersymbolB.gif when power switch is on (shutter pre-release switch is off). (Approx. 100 powersymbolB.gif when R
2 lever is on.)
3. Approx. 180 when illuminator is off while shutter pre-release timer is on; Approx. 220powersymbolA.gif when illuminator is on while shutter pre-release timer is on. See

High Speed Battery Pack MB-21 which makes a Nikon F4s

The more common combination for a Nikon F4 is using it with a High Speed Battery Pack MB-21 which consists of a base with battery holder and a grip unit, each of which contains three AA-type alkaline or NiCd batteries. Shutter release button with lock function is provided at the bottom of the grip - convenient when shooting with the camera held vertically. Also included are battery checker LEDs and a remote terminal. In additional to that, there is a Nikon External Power Regulator MB-22, powered by an external constant-current power supply, consists of a grip, in common with the MB-21, and a main unit. The External Power Cord MC-11 plugs into the external power terminal of the MB-22.

An interesting note in relation to
changes of these Power Packs with a basic Nikon F4 camera body will also change the respective model name for the F4: i.e. A high speed power pack equipped Nikon F4 is termed as a Nikon F4s, a Multi-Power Pack MB-23 mounted camera is referred as Nikon F4e. However, the less popular MB-22 is essentially a power regulator and there is specific designation if such combination is used.

One important aspect of the MB-21 is a secondary shutter release button provided to facilitate vertical format shooting -as finally, Nikon listens ...this feature was missed out on the Nikon F3/MD-4 combination.

Specification for High Speed Battery Pack MB-21

Usable Nikon camera(s): Nikon F4 Series, a standard equipment for F4s
Power source: Six AA alkaline-manganese batteries or Ni-Cd batteries (Battery selector SW provided)

mb21vertical.jpg
Remote terminal: Located at the front side. Remote cord MC-12A, Connecting cord MC-17, Terminal shutter MR-3 and other older type cords are usable.
Vertical shot: Shutter release button is provided at the bottom of grip. (Power SW and Prerelease SW also available.)

Battery checker: Battery checker LED's provided

* Alkaline-manganese batteries: When push button is pushed - LED 1&2 light up - Battery power sufficient; Only LED2 lights up - Battery power insufficient, but batteries can be used when one LED indicator lights up, even though the film does not advance at regular high film advance rates.

**Ni-Cd batteries: When push button is pushed - LED2 light up - Battery power sufficient; LED2 not light up - Battery power insufficient. In both power sources used, it is recommended to change the battery when no LED indicator lights up, even if the shutter release operation is not locked.

W A R N I N G: The New G-SERIES Nikkor lenses have no aperture ring on the lense, they cannot adjust aperture(s) when operating in manual exposure control even with certain earlier AF Nikon SLR camera models. Similarly, not ALL features provide in a modern AF-S series AF-Nikkor lenses can be utilized fully with a Nikon F4. Please refer to your local distributor for compatibility issue(s).
