DR. EMIL MAYER’S
Automatic Exposure-Meters

Patent —June 8, 1926

‘These meters are small photometers, which measure expo-
sure automatically with scientific precision under all con-
ditions of illumination, They do so without necessitating
assumption of conditions and computations as with tables,
‘without perishable sensitized paper, without personal element
in the definition of image detail, subject to extinetion,

‘They are independent of altitude, climate, hour, season and
geographic position,

Permanently adjustable to individual eyesight.

Correct exposures for sun and twilight, studios, interiors,
reproductions, mountain scenes and seascapes, daylight or
artificial illumination,

Direct reading for Extra Rapid material (ER), like roll
film, film pack, par-speed cut film, regular Ciné film, ete.

Sole leather cases, hand sewn, are supplied with every
instrument. ‘These cases are provided with means to carry
the meter on the belt, attached to a button, or alongside the
camera case; they permit the meter to remain adjusted for
instant use at whatever focal extension corresponds to the
user's eyesight.

Models, marked I, are for nearsighted persons, and
models, marked II, are for farsighted users: normal or
almost normal eyesight permits the use of either model.
