I have TWO tele converters for the Minolta system. One is a Soligor brand and the other is Albinar. I haven't ever used these, as they came with a Minolta set that my Mom gave me.
Also, I have a set of Soligor 55mm close up filters (+1, +2 and +3) which I HAVE used.
How about $10 each plus shipping?
If you buy it all I will give it to you for $25 shipped! Woo-Hoo!
