RE: Opinions Wanted: Vivitar 2x Macro Focussing Teleconverter

[J. C. O'Connell]

Here's my opinion on TC's:

They Suck compared to real primes at the desired
focal length. Especially for 35mm use. I have
one for 6X7 that degrades quality just like the
35mm ones do but at least with 6X7 the quality
level is still acceptable. 35mm Lenses are cheap,
why not just buy the focal lengths you want ( hint,
for 35mm I have everything from 15 to 1000mm ).
