    Certain lenses from companies like Vivitar were on a par with the manufacturers own. Vivitar are a design house, their top range of lenses the S1's were built by various manufacturers for them including Kiron, to Vivitar's specifications and quality controls. The S1 range was the first that achieved a quality both optically and mechanically that rivalled the major camera makers own lenses, Tamron brought out there SP range to compete.

    Some of Kiron's own lenses were equally as good optically and so shouldn't be dismissed lightly.

    Look at the prices for a Kiron 28mm f2 on ebay....unless you think they are all idiots to pay so much....then there is the Kiron/lester a dine 105mm (f2.8) macro, these are snapped up for £100-£200 each.

    The suggestion of "oil on the blades" is correct. The solution from Phenix is correct although I would disagree with the statement that this happens every two or three years. If the lens is correctly serviced it would include relubrication with a proper lube.
    This is also a relatively common problem with the Zuiko lenses in several focal lengths.
    for pancho-press The Kiron lenses have been sold under many names including the early Vivitar Series Ones that had a great reputation.
    Heavily sedated for your protection.

    The suggestion that you carefully consider dismissing Kiron is a valid idea. The company was founded by some engineers who left Nikon and Nikkor. They made some good lenses, although admittedly, they did not make their own glass as Nikon and Minolta did.

    And, yes, the modern lubricants will really help with that migrating lubricant contaminated aperture blade problem.

    When they ask you; "How many Mega Pixels you got in your camera?"
    just tell them; "I use activated silver bromide crystals tor my image storage media."

    The lubricant has broken down and migrated onto the appy blades. It's quite a good lens, and worth repairing. I believe we have the repair manual in the Kiron Klub files.

    KK is the subject matter expert.

    Every Kiron lens he has ever recommended I purchase has out-performed the Nikkor equivalents that I own.

    If he says it's worth getting fixed, then you should do what he says.

    KK is da man for Kiron.
    Get the right tools,lots of information and have a go at repairing it yourself.
    S.K Grimes spanners are the best.Lighter fluid will remove to oil.
    This is a Canadian perspective.Sending a lens to my nearest Can. repair center cost $100.00 (just to open the box).Then +++ depending on what they do.

    So nothing ventured - nothing gained. Go look at Kiron Kids Yahoo Group, he indicated that there were repair manuals there.

    It might be relatively easy to clean the diaphragm your self, I've fixed 3 or 3 lenses over the years and it wasn't difficult at all.

    I've taken a breech lock canon fd 50mm lens apart to clean the elements with no problem, and the blades were exposed, maybe drops of lighter fuel would free them on yours......then a piece of cotton (or similar) to dry up any mess.
    As Ian Grant said..you have nothing to lose, but you might get a reasonable price on ebay for the lens, if you didn't want to attempt it yourself.
