For Practical Bolex H16 Filming
Iris Type Fader
Bolex Product Code :- IRIPA
Before
the introduction of the variable shutter on the H16 the only way a fade
in or fade out could be accomplished in camera was with the use of this
accessory.
Paillard Bolex sold it as the totally closing iris assembly (also known as the Iris Vignette). This device screwed into the front thread of the early versions of the following Kern lenses.
25mm f1.4 Switar
25mm f1.5 Switar
26mm f1.9 Pizar
25mm Genevar
It cannot be fitted into the normal front filter mount (32mm) found on the later Kern lenses. More a curiosity than something that useful today
The
unit gives the effect of defocused brackets coming in from the left and
right side of the picture.
It does not do a circular iris fade and certainly
not the fade to black of the later variable shutter
.
