Other Features
Non-rotating Front Barrel.
Your Kiron 105mm f2.8 lens is equipped with a non-rotating front
barrel, which means that the front barrel of the lens does not rotate as the lens is
focused. Position-sensitive filters, such as polarizers, and special effects filters, or filter masks
retain their orientation as the lens is focused.
Built-in Lens Hood.
The Kiron 105mm f2.8 has a built-in, retractable lens hood which, when
extended, will help to control stray light. All Kiron lenses feature full multicoating, with lens
element edges that are hand-blackened to prevent lens flare, and assure high contrast and
excellent color rendition.
General Information
Choose optical accessories, such as filters, with the same regard to quality you used when
buying this lens. Low quality accessories will compromise the high quality results you
expect from your Kiron lens.
Take normal care to protect your lens from fingerprints, dirt, sand, and water. Remove dust with
a soft lens brush, or gentle puff of compressed air. Remove fingerprints or other marks with
photographic lens tissue moistened with photographic lens cleaner. Never rub the lens with
dry tissue or any other material, since this can scratch the coatings.
When your lens is being stored, keep it in a cool, dry place with front and rear caps
attached.
NOTE: If you live in a humid climate, it is important that your lens be stored with a small package
of silica gel (such as the one supplied) at all times. This will help to prevent fungus, a result of
high humidity, from forming in the lens.
