Pentax 67 Interchangeable Lenses User manual

Careful reading of this operating manual
will help you take advantages of all the
photographic capacities this equipment
has to offer.

Since accessories made by other manufac-
turers are not produced to the precise
Pentax specifications, they may cause
difficulties (inferior image quality, vignet-
ting, etc.) or actual damage.
Therefore, we suggest that you use only
genuine Pentax accessories on your Pentax
cameras and lenses.




Photographs and/or illustrations of the
products in this operating manual may
differ from the actual product in its details.

Dismounted lenses should be handled carefully.
Place them on a level surface to prevent falling
over or rolling away.
Generally, smaller lenses should be stood on
their front end, with the mount capped like the
three lenses in the center of the photo. The SMC
Pentax Fish-Eye 35mm lens must stand on its
rear end with mount cap to avoid scratching the
protruding front element. Long telephoto lenses
with tripod should be placed lengthwise on their
side as shown in the photo.
