10.5 Lens Maintenance
Never touch the inner optics of the lens with your fingers. Keep the inner
optics perfectly clean with air, a lens brush or the dry cloth delivered with
the lens.
Do not touch the contacts. Keep the contacts clean with either a dry cloth
or by using a fiberglass brush. Do not use any other tools on the lens.
The lens is not waterproof. It should be immediately dried with a cloth
if it becomes wet. If it is exposed to salt, moisten a cloth, wring it and
carefully clean.
10.6 Back Maintenance
Cleaning the IR Filter
The Leaf Credo back must have the protection plate fitted when it is
not attached to a camera. Dust may accumulate on the IR filter, which
degrades the image quality if not removed. Follow the directions found at
http://www.mamiyaleaf.com/cleaning.asp.
10.7 IR Filter on the CCD
The IR filter (Infrared reduction filter) is permanently mounted on top of
the CCD. The filter may not be removed for several reasons:
• The focusing of the Leaf Credo back camera back can be altered.
• It is only possible to remount the filter without dust getting in between
the filter and the CCD if you have access to special clean room
facilities.
• The Mamiya Leaf Product Warranty is terminated.
