    Cons: once you get use to the silver color, all is good !

    Pros: Lightweight...... and this copy (version 1) seems to have good very optics, this unit is unexpectedly SHARP

    Summary: I have seen A LOT of modern plastic junk out there (as we actually do lens repair) where the plastics are breaking all the time, This lenses build is plastic, but maybe to a different standard. This unit we got is silver and it is the first generation of this lens. When it first arrived in it was kind like a like a joke, well lets toss it on a SONY and see if it even focuses. Well, I have tested 1000+ lenses and I was shocked to see the images off of this lens ! Maybe a rare find, who knows. This lens was a COSINA, i.e.: 09 or 9 in the serial number = Cosina. but they have been making lenses for a long time and I would imagine they took all their past experience and put it towards a lens like this. Although plastic and aimed at a lower cost market, they seem to somehow get this design right. We have not tested it with a hood but flare does not seem to be an issue, an the coatings do look strange in color. In the end, Im glad to add this lens into a 500 + collection, its still hanging out on a SONY A99.. for now at least.

    Cons: All plastic, mount included. Small glass diameter. Inexpensive coatings. Very poor quality and performing clutch mechanism

    Pros: It\'s dirt cheap and Made in Japan. The last attempt by Cosina to do AF lenses...

    Summary: There are 2 versions of this; a first edition with a rotating zoom and second edition in Silver or Black with push-pull zoom. This was by the Vivitar group of employees, investors, and interested parties who took ownership operation and contracted with Cosina to build lenses. This first edition weighs 430 G and the second 500 G. This ownership group folded and sold out in 1998, manufacturing was Korean following
