Flash Photography
In infrared photography, some adjustment must be made in the focus in order to retain sharpness on the film, because the
invisible infrared rays are longer in wave length than the visible rays used for focusing.
For infrared photography1. Use a R
filter or equivalent
with an infrared (black-and
white) film.
2. The red-colored line, next to the orange-colored distance index, is the infrared index.
3. After focusing in the normal manner, re-set the distance indicated by the orangecolored distance index to the infrared index, by
shifting the distance ring.
4. Follow instructions enclosed with the infrared film and filter and, to be on the safe side, make several bracketing shots. In
general, more exposure rather than less seems to be a safe guide.
A. Always use flash cords with a standard PC type plug. When detaching the flash cord, grip the plug firmly and pull it out straight,
instead of using a twisting action.
B. The lens shutter of the Zenzanon-S lens has a X-setting for flash synchronization, which means that electronic flash units will
synchronize at all shutter speed settings, up to the fastest 1/500 second.
This means, of course, that flash fill-in for daylight shots can also be made very easily.
A. To make multiple exposures, turn the multiple exposure lever in the arrow-indicated direction before exposing the first shot.
When the shutter release button is depressed, in this condition, the shutter will be released any number of times without advancing
the film.
