Another interesting solution is the Macro Focusing Teleconverter. They
were marketed by Vivitar, Soligor, Tamron and others. Most of them look
identical and probably are. A list member has suggested that the Tamron
may be different. In any case, they convert a lens to twice it's focal
length at 2 stops less speed like regular converters, but they add an
additional helical focusing mechanism for focusing closer. A standard 50mm
lens that focuses to about 18in. becomes a 100mm (f1.4=>f2.8, f1.8=>f3.6)
lens that focuses to 1:1.
Hi DM,
Here's a picture of a trout lily that I shot last week with the 50mm, f1.8
and a Vivitar 2x Macro Teleconverter -

I think the image sharpness is acceptable with this combination but the
bokeh isn't nearly as pleasing (to me) as what I get with the Kiron
105mm. I was thinking of replacing the Kiron in my kit with the
teleconverter since I always carry the 50mm anyway but I think I've changed
my mind again, for about the 10th time. I'm back to carrying the Kiron in
my pack unless I really want to cut down on the weight for some reason -
like a several day trip by plane where the primary subjects will be other
than macros.
Later,
Johnny
