Lens help.

[beautifulfreak]

I purchase 2 lenses at a thrift today(the were cheap and i am the curious sort) and I am not sure exactly what they are for, they have no branding on them other than the word Japan. One is a tele converter lens x1.5 and the other is a wide converter lens x0.6. They came with 3 rings that make the lenses fit a variety of different lenses. They fit my old Konica and old Pentax but I don't know what they do other than make the camera very heavy. I tried google but gave up finding something useful on search result page 11. I don't know much about lenses other than zoom, macro, and micro. Any explanation or links to useful info as to their use is appreciated. thanks

The teleconverter makes everything seem closer - like a fixed zoom lens.

The Wide converter makes the angle of the view wider - you can fit more into the frame.

I have virtually the same set (although not unbranded) for my old Yashica rangefinder. Back in the day alot of cameras only had one fixed lens, so they made these adaptors to fit on the lens and allow a little more flexibility. They were extremely expensive when they were released!

The easiest way to get the feel of them is to go out and use them. Are you using them on a SLR or a rangefinder? If they're on a rangefinder then you'll need an adaptor that fits on the hotshoe to tell you what you'll actually be seeing through the lens, since it will make it different to the usual viewfinder.
