Hi Boris,
I've tested the Sigma 50/2.8 EX Macro with a
Tokina Doubler and have posted a picture here:

Make of it what you will.
It's Rob Studdert's printable version of the
USAF test chart and I personally don't know
what to make of it either. The print starts
off being lousy because my printer is crap.
The chart is 146cm from the sensor plane and
I used a flash.
This is not the way one usually employs these
charts, but it may give you some useful
information.

Hi!
A Russian Penta Club member approached me asking to sell him my Tamron
90/2.5 lens. I agreed. Same reason - unfortunately the lens is manual
focus.
I am thinking of replacement. KEH has now very good variety of macro
lenses at rather reasonable prices. Say, Sigma 50/2.8 EX macro goes for
$144.
Though this may appear rather heretic I am thinking of lowly SMCP FA
100/3.5 (with attachment, which I believe is just a close up filter).
Why - because the darn thing is small.
Anyone here who owns such a beast - how it performs between f/3.5 and
f/5.6?
I realize that SMCP FA 100/2.8 is better, probably far better, but it is
big and most probably I will not use too often, because of its size.
Any feedback will be appreciated.
Thanks.
Boris
