Re: TTL Flash for Macros

[Peter J. Alling]

Lon recommended the Macro focusing version, (7 element), it's available 
in K or KA mount, I'd get the KA version if I bought
another one.

I should look into the Vivitar 2x TC.  Which one would you recommend?  I think they 
have a 7 element version that's supposed to be optically pretty good.
My Sigma 2X doesn't work due to the rear-element of my vivitar 105/2.5 Macro hitting 
the front element of the TC.  I have used both the 2x and 1.4x sigmas on my sigma 
300mm Macro with good results.  But the 300  with a 2x TC is hard to focus and being 
pretty heavy is hard to chase bugs with.

Christian, have you tried a 2x TC on a fast macro
for such shots?  I've used the Vivitar Macro 2x TC
on both a Kiron 100mm f2.8 macro and the K 135mm f2.5
with surprisingly good results.

For extra magnification (2x and beyond) I use stacked lenses but my results
haven't been great, but that's a user problem....
