Sigma 20 F1.8 EX Aspherical DG DF RF
But unfortunately the serial number begins with 1xxxxxx and it's not recognizable by A900 and KM 7D

However on the old Minolta 7000 all works fine.
I'm wondering to try the same thing here - http://www.photoclubalpha.com/2009/03/0 ... ck-rechip/

I there any chance to get things working, if I order chip programmed with 20mm and f/1.7 Aperture and fit in the lens mount ? Anyone tried this with similar lens ? There are 8 pins.
Any help will be appreciated, and sorry for my English.
