Kodak Retina Reflex - The Retina Reflex IV, III and S Lenses; Wide-Angle Lenses

approximately 10 sec., giving the operator time to take his place in the picture. Once the lever has been
set to "V", the position cannot be altered any more. On releasing, the lever will automatically move back
to the X position.
FLASH SETTINGS. For X- or M-synchronization, set the lever at the right of the shutter (on the lower part
of the shutter on earlier Reflex models) to X or M, at the same time depressing the small protruding lock,
as for the self-timer setting.
THE RETINA REFLEX IV, III AND S LENSES
The Retina Reflex IV, III and S lenses are interchangeable, being held in place by quick-change bayonet fitting.
The shutter is situated behind the lens, and any lens inserted can be accurately focused by both the split-image
rangefinder and the ground glass focusing screen. As the taking lens is at the same time the finder lens, you
always see the correct view in the finder with any lens used.
The iris diaphragm of all lenses couples up automatically with the aperture-speed controls on the shutter, and
with the pre-selector mechanism that stops down the lens on releasing the shutter.
Wide-Angle Lenses
The 1 1/8 in. (28 mm.) Retina Curtagon f4 covers an angle of 76° as compared with the standard lens of 47°,
and is an ultra-wide angle lens.
The 1 1/8 in. (30 mm.) Retina Eurygon f2.8 has a slightly smaller angle of view than the 28 mm. lens, but is
intended for the same applications.
The 1 3/8 in. (35 mm.) Retina Curtagon f2.8 and Retina Eurygon f4 cover an angle of 64° and are normal wide-
angle lenses. The focusing range of the wide-angle lenses extends from infinity down to 3 ft.
The 28 mm. and 30 mm. lenses take 60 mm. filters; no lens hood is required, the lens being sufficiently
recessed in the mount.
The 35 mm. lens takes 32 mm. filters and a special rectangular bayonet lens hood.
Tele Lenses
The 3 3/8 in. (85 mm.) Retina Tele-Arton and Retina Rotelar f4 cover an angle of 28° as compared with the
standard lens of 47°. The focusing range of the 85 mm. lenses extends from infinity to 6 ft.
The 5 3/8 in. (135 mm.) Retina Tele-Xenar and Retina Rotelar f4 cover an angle of 19°.
The focusing range of the 135 mm. lenses extends from infinity to 14 ft. For close-ups with this lens, see below.
The 7 7/8 in. (200 mm.) Tele-Xenar focuses from infinity to 25 ft. and covers an angle of 12°.
The 85 mm. lens accepts 32 mm. filters and uses the rectangular bayonet hood (as used for the 35 mm. lens)
with a supplementary attachment.
The 135 mm. lens accepts 60 mm. filters and uses a round slip-on lens hood.
