in all honesty, I have to agree with you on their IQ. it was my attempt to " skin the cat " lacking 10-15 mm fisheye.

Originally posted by texandrews Thank you for posting those, and your quick response. Much appreciated. But you misunderstood me: I meant, what were the specific models of the wide angle conversion lenses, the screw-ins. There are a number available, ranging from very inexpensive to ones over $1000.00. Although I rather agree with LA_Photographer above about the IQ of these specific examples.
mine are " el cheapo's ", I tried one of the more expensive ones with even worse results. I too await imput from someone with better results. a 10 or 15 mm would be nice, but seeing the prices of the newly made 645 lenses, we'd be talking $6000.00 or better.
