The ESM motor which fits onto all H16 cameras equipped with the 1:1 spindle is designed for filming with synchronous sound recording. This electronically regulated auxiliary motor drives the film at the perfectly stabilized speeds of 10, 18, 24, 25 and 50 f.p.s. It is used with the same crystal/sync pulse accessory as the H16 EL camera. It is provided with an automatic clapper device which fogs a few frames at the beginning of each take.

This grip, fitted with a quick attachment device, has a compartment for the power pack 12V / 1Ah, (code 261110), as well as a start button and a button for the diaphragm preselection of the Kern Vario-Switar 100 POE lens. Designed to fit the contours of the hand, the grip can be swivelled to the most convenient position, and the length of its strap adjusted, thus ensuring excellent control over the camera. Code: 261001.

Crystal/sync pulse (PQM accessory)
For H16 EBM + H16 EL cameras as well as for H16 RX-5 + H16 SBM cameras equipped with ESM motor.
This basic equipment gives the following possibilities:
Synchronisation of the camera mechanism on the frequency of y crystal, making it possible to guarantee the precision of the filming speeds of 24 and 25 f.p.s. to within a margin of error of less than 0.002%, from -20°C to + 50°C (less than 1/4 of a frame out in 400 feet of film).
Transmission of a sync pulse proportional to the camera speed (60 cycles at 24 f.p.s. or 50 cycles at 25 f.p.s, 50 cycles at 24 f.p.s. on the special model).
Transmission of a 12V DC clapper signal (3 different standards of automatic clapper).
Dimensions: 135 x 57 x 35mm.
  Two version are avavailable:
Unit for setting to 24 f.p.s. 60 cycles or 25 f.p.s. 50 cycles, with 1m connecting cable and protective cover. Code: 262221.
Unit for 24 f.p.s. 50 cycles only, with 1m connecting cable and protective cover. Code 262331.

Supplied with a set of masks and acetate sheets.
Code: 266220.

FORMER KERN VARIO-SWITAR 100 PTL              1:2/f = 12.5 - 100MM f/2 MC WITH ASPHERON 6.5MM
With an 8x zoom, a useful wide angle setting of 12.5mm and the Aspheron 6.5mm optical attachment, this is a multi-purpose lens. It has a built-in TTL exposure meter and power zoom with variable speeds.
The lens has 19 elements and is multicoated (MC), so that an overall increase in contrast has been achieved, resulting in better shots particularly when filming against the light.

The most important technical features:
Horizontal field angle from 41° (752 ‰) to 5 1/2° (96 ‰). With the Aspheron 72° (1450 ‰).
Geometric apertures from f/2 to f/16, with
mark for photometric apertures (T-stop).
Focusing from 1.2m to infinity. A special control makes it possible to focus sharply at very short distances, particularly necessary when using the aspheron wide-angle attachment.
The Aspheron was designed specially for use with the Kern Vario-Switar 100 PTL and, even with the diaphragm fully open, has a focusing range from 1m to infinity and is practically distortion free.
Two-blade automatic diaphragm - can also be set manually - with CdS photo-electric cell in the lens behind the zoom variator and centre-weighted measuring field over 2/3rds of the image area. This lens can still be serviced today.


Available in C-mount version or equipped with bayonet adapter.

Kern lenses incorporate an exclusive automatic depth-of-field scale (Visifocus - orange dots).
