What was your thinking behind using the converter?
More working distance? This is a superb lens and
I've said so on several occasions, but there has
been no response. I presumed this was because
there are not many of us using them. The Pentax
100mm seems to be far more popular although not as
good overall -- according to the tests I've seen.

Sigma 50mm EX Macro plus the Pentax Rear Converter-A 2X-S.
Comments, critique encouraged.
The f stop reported to the camera is wrong with this combo. Wide open it
tells me the 2.8 lens is a 1.4 and of course the combination is really 5.6.
The exposure is fine and when set to A the camera adjusts the diaphragm
properly. Just the numbers are wrong. Anyone know if this can be fixed?
Bit of an annoyance but not a real problem.
