| Viewfinder |
|
| Viewfinder principle |
Large, bright, combined bright-line viewfinder with automatic parallax compensation |
| Eyepiece |
Adjusted to –0.5 dioptres; correction lenses available for –3 to +3 dioptres |
| Image field framing |
By projection of pairs of bright-line frames for 28 and 90 mm, 35 and 135 mm, 50 and 75 mm lenses; automatic display of corresponding frames when lenses are locked into the bayonet mount |
| Frame selector |
Lever enabling alternative frame pairs to be displayed in the viewfinder without changing lenses (e.g. for framing comparisons) |
| Parallax compensation |
The horizontal and vertical differences between the viewfinder and lens axes are automatically compensated for in relation to the focusing distance |
| Concordance of viewfinder and film image |
The bright-line frame size corresponds to an image size of approx. 23 × 35 mm at the minimum focusing distance for all focal lengths; focused at infinity, and depending on the focal length, approx. 9% (28 mm) to 23% (135 mm) more will be captured on the film than is shown in the corresponding brightline frame |
| Magnification |
0.72× (for all lenses) |
| Long-base rangefinder |
Coincident and superimposed image rangefinder, shown as a bright field at the centre of the viewfinder image |
| Effective rangefinder base |
49.9 mm (mechanical rangefinder base 69.25 mm × viewfinder magnification 0.72×) |
