Hi Joe, That's funny, I'd heard that the Sigma had bad edge sharpness and light fall off issues. Apparently not true? I have the EX 50 Macro, I'm not impressed, the Pentax F/FA is much better IMHO. Autofocus is actually the issue, the D is rather poor in low light anyway, at 5.6 it's hopeless without a beam or the clever Pentax 'flashy,flashy' from the strobe. (Both of which are unacceptable to me in any type of 'candid' work.) At 4.0 it sort of works, at 2.8 it's not too bad. My eyesight isn't too swift in low light either.
$500.00 is about the range I'm looking for, I'll keep my eyes open, thanks.
