    Somewhere I have a Vivitar 24-70 Series 1 in Minolta MD mount. It needs some work or I would have tested already. Has anyone here used that lens?

    All of the Series 1 24-70's, were made by Cosina. Sadly, when Cosina began maunufacturing Viv S-1 lenses , the quality usually suffered. No fault of Cosina. They make it to the designers price point, and are very capable of making fine, well made lenses. In this case, it's a decent lens, nothing special, nothing crappy. The Cosina made Viv S-1 200mm f/3.5AF (also made by Komine) lens is very good, and even beats out the legendary Nikon 180mm f/2.8 lens. What kind of work does it need? You may actually be quite pleased with it's performance.

    I guess I've been spoiled by the fact that most of my lenses for 35mm format are the new type Canon FD ones that have plastic barrels, and are much lighter.

    Yes, but they can't take the abuse, wear and tear of the older models...

    Not so; many, many years of use, abuse, accidents, etc.

    I sort of got the impression that some of the later products weren't as well made and that the brand got diluted by slapping "Series 1" on point and shoot cameras and other decidedly low-level gear.

    Sadly, there is some truth to that statement.

    I'm not sure about that, to say the barrels are plastic is an over simplification they are a specially developed plastic that Canon said at the time they were convinced was a better material and about half the weight of the metal barrels and it enabled them to embed the lens elements in the molten plastic to make them less subject to shock damage, and Teflon coat the focusing helicoids to make them very smooth. Most of my lenses with the exception of two are the new type, and after around twenty years regular use are still as good as the day I bought them, I know that what you say is the accepted wisdom but it's not borne out by my experience, or anyone I know who uses them.

    Plastic is just a single term which can be used to describe a variety of materials which have a variety of properties - some of which are suited to mass production of precision pieces and some are not.

    It's a bit like saying that a hammer is only any good if it's made out of metal - but which metal? Steel, lead, copper, mercury?

    I agree with Benjiboy's comment from Canon that there are some engineering plastics that can be a better choice for some precision parts than machined metal.

    Vivitar Series 1 lens opinions

    Kiron Kid, you state that

    "The Cosina made Viv S-1 200mm f/3.5AF (also made by Komine) lens is very good, and even beats out the legendary Nikon 180mm f/2.8 lens"

    I just looked at my 200/3 Vivitar Series 1 in Konica AR mount. It has the Komine 28XXX... serial number. What I've read is that the 200/3.5 AF has the same optical design as the 200/3 but has a beam splitter built in and that this reduces the amount of light striking the film. Did Komine supply the lens elements to Cosina for this lens?

    I find the close focusing of the 200/3 very handy in situations where I can't get any closer to the subject.
