Mounting And Removing Lenses; Incompatible Lenses; Mounting An M-Mount Lens - Epson R-D1s User Manual

Mounting and Removing Lenses

The camera accepts a wide variety of M-type bayonet mount
(M-mount) lenses. You can also use L-type screw mount (L-mount)
lenses by attaching a third-party adapter ring.

Incompatible Lenses

Certain lenses are not compatible with the camera due to physical
constraints:
❏ Lenses that project more than 20.5 mm into the camera body.
These lenses cannot be used because they may touch the inner
parts of the camera. Some models known to be incompatible
include:
❏ Hologon 15 mm F8
❏ Super Angulon 21 mm F3.4
❏ Super Angulon 21 mm F4
❏ Elmarit 28 mm F2.8 (earliest model)
❏ Summicron 50 mm (Dual Range Summicron)
❏ Collapsible lenses.
However collapsible lenses such as the Hektor 50 mm F2.5 or the
Elmar 50 mm F3.5 can be used with the camera as long as the lens
barrel is not pushed into the camera body. Be very careful if using
these types of lenses.
❏ Lenses that have an auxiliary viewfinder lens.
These lenses cannot be used effectively because the baseline length
is different from the one used for this camera.

Mounting an M-mount Lens

1. Align the dot on the lens with the red dot on the lens release button.
Caution:
c
❏ Do not touch the inner parts of the camera.
❏ Beware of dust particles entering the camera body.
2. Insert the lens into the camera body, then turn the lens clockwise
until it clicks.
