38. DIOPTRIC LENSES
The viewfinder eyepiece has a built-in -1 correction (suitable for most normal vision).
If a dioptric lens is fitted, you do not have to wear eye-glasses when taking pictures. Slip the lens in the
groove in the finder eyepiece.
Dioptric lenses are available in 7 types: -4, -3, -2, -1, +1, +2 and +3 (Diopters)
Note: Some forms of astigmatism etc. may make dioptric eyepiece correction impossible. Please
check with your vision specialist for a recommendation based on your prescription.
39. SUPER DATA BACK 4
One of the most versatile databacks offered anywhere, the
Super Data Back 4 allows you to imprint a choice of date,
time, or date plus time, and up to 10 characters from a
choice of a full alphabet, a set of symbols and digits 0 - 9 in
two lines. So, for example, you can record the date, time and
place of a photograph when traveling, or make a note of
birthdays and other special events.
It also incorporates a release timer, interval timer and very
long exposure time controller, and gives you control over the
number of exposures in a sequence to be made. (Fig. 108)
40. DATA BACK 3
When the Back Cover of the camera is replaced by the Data Back 3, "year, month and date", or "hour,
minute" can be printed on your film.
The automatic dating mechanism is incorporated into the Data Back 3. Once the date is set, no
adjustment is necessary until 2019, because leap years and months with 31 or less days are
automatically adjusted. When the switch is turned OFF, it can be used as digital watch. (Fig 109)
