Hi Ralph, I wasn't trying to insinuate that you thought that a Kiron zoom would be as sharp as a prime lens. I was just agreeing with you that Kiron were indeed good lenses. I was just using my friends opinion as an example. I'm sorry that you misunderstood me.
I'm a small time Ebay seller to help afford my photography hobby. I have noticed that aftermarket lenses such as Kiron, Tamron SP, Tokina ATX and Vivitar Series I (although fine performers) just don't bring any money if you try to sell them. It seems the demand is just not there anymore.
