Hi Klaus,

I have two questions

1. you metioned "min. focus distance 0.38m (max. magnification ratio ~1:1)"

From where you get this info? The sigma site not metioned MFD of OS version

2. According to PZ reviews the non OS and OS version have the same MFD. Since OS version is longer it means that min working distance of OS version is shorter. Am I correct?



I'm asking this question because most people choose longer macro lens for greater working distance
