The Nikon FM3A comes with a new group of interchangeable focusing screens. Different types of focusing screens can be used with this camera. The K3-type Spliprism-image Rangefinder Microprism screen comes with the camera as a standard accessory. Similarly to the older versions for the FM2n/FE2 and FA where three types of screens are available; the new screen comprised of an addition choice of Matte system and an Etched system with horizontal and vertical lines option as optional accessories.

In comparison with the previous Nikon FM2n, there is a noticeable difference in contrast and brightness. My first experience using the screen is, it is very 'clear' which I think has a lot to do with the overall improvement done on the fine matte/fresnel outter field. Although personally, I would like to see an additional screen with 45° cross split image rangefinder add to screen's selection but looked like Nikon has firmly decided sticking to old selection of only three screen types for the midrange bodies. Anyway, compatibility issues will be addressed in other section and we will just focus on the new screen type for the Nikon FM3A.

Changing the Focusing Screen Other than the K3-type Spliprism-image Rangefinder Microprism screen, two types of screen are available for optional replacement: B3 type (Clear Matte IIa) and E3 type (Etched screen with horizontal and vertical lines). Select the one that matches your particular requirements and/or personal preferences. When you buy a new screen, it will come with a casing containing the focusing screen with a special tweezer that is used for screen changing. However, since most seasoned photographers may, in one way or another experience changing a screen before and may often use hand as substitute You can do that - as long as you know how to do it carefully (and what to expect... with a dirty screen when it is wrongly done). A dirty screen will not affect image output, but it is very irritating and uncomfortable to view through the lens. Anyway, here are some illustrations for those careful user:

Pull the focusing screen release latch towards you using the special tweezers. The focusing screen should drop down. The special tweezers are supplied with a focusing screen for replacement.

Grip the screen by pinching the tab of the screen and remove it.

Place another screen on the screen holder.

Be sure to place the screen in the right position on the holder

Push the front edge of the holder upward to secure the screen.
Push up on the holder until it snaps into place.

Spliprism-image Rangefinder Microprism Screen
Suitable for general photography. it has a microprism collar around the central splitprism-image rangefinder spot. With a PC lenses or lenses having a maximum aperture less than f4.5, the splitprism-image rangefinder or microprism collar is dim. In this case, focus on the surrounding matte area.

Clear Matte Screen IIa
Works well for general photography, close-up photography, and duplication work. Especially useful for people who prefer to focus on the matte focusing spot at the center of the screen, or when it is inconvenient to use the splitprism-image rangefinder for focusing, as is the case with super telephoto lenses and/or slower speed zoom lenses.

Etched system with horizontal
and vertical lines
Extremely useful in pictorial composition. It consists of a B3-type matte field with etched horizontal and vertical lines. A good choice to register positioning during architectural, multiple exposure operation and also useful with PC (Perspective Control) lenses.

NOTE: Good news is - When you use a new K3, B3, or E3 screen type specially designed for FM3A camera with an Nikon FA, FE2 or Nikon FM2(n) camera, NO exposure compensation is required.

How to distinguish the applicable types.
