I agree with Barry's assessment.
I have a 1.5x 3 element (Soligor) and a 2x 7 element (Vivitar). I bought
these through B&HPhoto (used) and they are not matched multipliers. You can
buy them cheap on eBay or elsewhere for under $30.00. For these prices, you
can experiment with them. For my case(s), they have been a good buy. I have
tried the 1.5x and 2x on a 28-70 Vivitar Series 1 zoom with mixed results.
There was some loss of image quality using the 2x towards the higher end.
That's my $0.02
