Thank you for that great link you developed. I like the Geoali site, too. Thanks! Your Infinitys are beautiful. I don't think I am up to doing the tone generator proceedure. 'Wish you lived closer....lol...
By the way; do you know anyone interested in a Nikon F2 w/F1.4 and hard leather case? Not used in 20 years(yes, I took the battery out). I think I have a couple of "telextenders", too.
