Kodak Retina Reflex - The Convertible Lenses; The Wide-Angle Units; The Tele Units; Lens Changing

The Wide-Angle Units
If the Retina Reflex is equipped with the standard Xenon C lens, only the 1 3/8 in. (35 mm.) Curtar-Xenon f4 or
f5.6 can be used as wide-angle unit. If the camera has a standard Heligon C lens, only the 1 3/8 in. (35 mm.)
Heligon C f4 or f5.6 can be fitted. These 35mm. lenses increase the angle of view to 64º compared with the 47º
of the standard lens.
The 35 mm. f5.6 lenses accept 32 mm. filters and the standard lens hood with supplementary rectangular
bayonet attachment.
The 35 mm. f4 lenses take 60 mm. filters and a round 60 mm. slip-on lens hood.
The Tele Units
If the Retina Reflex is equipped with the Xenon C as the standard lens, only the 3 1/8 in. (80 mm.) Longar
Xenon C f4 can be used as telephoto unit. Cameras with a Heligon C standard lens take the 3 1/8 in. (80 mm.)
Heligon C f4.
These 80 mm. lenses decrease the angle of view to 30º as compared with the 47º of the standard lens. They are
fully corrected.
The 80 mm. lenses take 60 mm. filters. The lens hood required forms part of the plastic container in which the
lens is supplied.
Lens Changing
To remove the interchangeable front component of the standard Retina Reflex lens, press the safety catch
inwards (towards the lens) and turn the front part of the lens in an anti-clockwise direction as far as it will go,
that is, until its red dot is opposite the red dot on the black outer rim of the lens mount. The lens can now be
lifted out. For easy removal and safe storage of the standard lens, the special container available for it should be
used. . .
To insert an alternative lens unit into the camera, place it in position over the mount so that the red dot on the
lens lies opposite to the red dot on the shutter rim. When the lens is seated, turn it firmly in a clockwise
direction as far as it will go to engage the bayonet lock. A slight click is usually audible.
The standard lens of the Retina Reflex must not be changed against a standard lens from another Retina Reflex
or from a Retina IIC or IIIC camera. Therefore, make sure that the serial number engraved on the lens itself is
the same as the serial number engraved on the bayonet mount front plate of the camera.
THE CONVERTIBLE LENSES
To change the lenses of the original Retina Reflex remove the front component by pressing the catch inwards
and turn the lens anticlockwise (left), then lift out (centre). When inserting a lens line up the red dot on the lens
component with the red dot on the front of the shutter. then turn clockwise to engage the bayonet lock.
