About this photographic site.

F3 without finder.jpg (14k)

* GO TO the newly revised Nikon F3 website

Type K screen: Combination of Type A and J screens. Matte/Fresnel field with 3 mm split image rangefinder spot surrounded by 1 mm-wide microprism doughnut. Rapid and accurate focusing for subjects with both straight lines and ill-defined contours. Suitable for general photography, which came in as the standard creen for F3. The 12mm circle also define and outlined the exact 80/20 metering area.

There are * not less than 20 types of focusing screens that you can used with the Nikon F3. Each provides you with the various functions that you think can best suit your kind of assignment or preferences. Other than the F3AF which you need to take out the focusing screen before you can mount your DX-1 Finder, each screen can work in conjunction with all the interchangeable viewfinders developed for the F3. Some screens can actualy be used on the F4 as well. So does the F4 screens can also be interchange and used on the F3. The advantage of the metering cells that housed underneath the main mirror box shows its potential here - virtually ALL interchangeable viewfinders and focusing screens need not to adjust or do any exposure compensation on its metering.

* In later stages, where some of the variation of the F3 like the F3AF, F3H came wihout or different from the standard K type screen. For example, the F3 High Speed used the Type B as standard.

Typo A: Mane/Fnesnel field wnh 3mmo circular spliMimage rangefinder spot and 12mmo reference circle. Rapid and accurate focusing. Excellent for general photography.

Type C: Fine-ground matte field with 4 mm clear spot and cross hair: For photomicrography - work especially well with the DW-4 finder, astrophotography and other high magnification applications, using parallax focusing on aeriai images.

Type J: Matte/Fresnel field with central microprism focusing spot and 12mmo circle. Good for general photography.

Type M: Fine-ground Fresnel field wnh 5.5 mm clear spot and double cross hair for use in parallax focusing on aerial image, plus millimeter scales for calculation of individual magnification of objects or for measuring objects. Brilliant image in dim light. Suitabe for close-ups, photomicrognaphy and other high-magnification applications. Another good companion with the DW-4 high magnification finder..
Type L: Same as Type A screen but with split-image rangefinder line at a 45° angle. Best work with subjects with horizontal lines.

Type G: Clear Fnesnel field with extra-bright 12mm microprism focusing spot for viewing and focusing in poor light. Four models (G1-G4) are available corresponding to specific focal length lenses.
* Depth of field cannot be observed

Type P: Same as Type K but with split-image rangefinder line at a 45° angle and etched horizontal and vertical lines as an aid to composition. Rapid and accurate focusing for subject with horizontal or vertical lines or ill-defined contours suitable for general photography.

Type H: Clear Fresnel field with microprism focusing panern over the entire screen area. Permits rapid focusing on any part of the screen with optimum edge-to-edge brightness in poor light. Available in 4 models (H1-H4) corresponding to particular focal length lenses.

Type B: Mane/Fresnel field with 3mm fine-ground matte focusing spot and 12mm reference circle. Good for general photography, especially with long lenses.

Type U: Matte/Fresne field wnh 3mm fine-ground matte focusing spot and 12mm refenence circle. Utilizes the same matte field as Type B, but with lenses longer than 100mm the image in the viewfinder is easier to see. * With shorter focal length lenses, this screen is not suitable because of light fall-off in the corners.

Type R: Same as Type A but with rangefindbr prisms of sloping surfaces at a smaller angle and horizontal and vertical lines to aid proper composition. Works best with lenses having maximum apertures from f 3.5 to f /5 6.
Type D: Overall fine-ground matte field. For specialized close-up photography and for use with long lenses.

Type S: Same with Type K, except at the left corner, there is a provision with used in conjunction with the 250 back and the MF-17 dadaback to register data imprint.

Type E: Matte/Fresnel field with 3mm fine ground matte spot, 12mm reference and etched horizontal and vertical lines. Ideal hr architectural photography, copying works etc .

Typo T: Mane/Fresnel field with split-image rangefinder, 12mm reference circle, and horizontal and vertical lines. Used when preparing slides for TV broadcasting. Dotted lines indicate standard TV screen format. Solid outline shows "safe action" area, whereas broken lines indicate "safe title" area.
How to change the screens in the F3, first , just use the finder to slide the finder release levers (on both sides), and lift the finder up.
Just use your finder and lift the screen up, replaced with the screen with of your choice.
