Sigma MF 24mm f/2.8, is it super-wide II or...

I really would like to know is that MTF 4 measured Sigma MF 24mm f/2.8 lens newer super-wide II or that older super-wide? I've tried to google for answer and it seems that most people assume it's super-wide II but I'm not convinced as description here at photodo doesn't say anything about this matter. Anyways there seems to be some confusion about it. Construction of the older lens seems to be more solid, so I'd be interested to know it has that sweet MTF 4.

I don't think that 24mm (even on the 35mm film format) comes anywhere near deserving the title of being a super-wide. That description should only appy to optics offering around 95+ degrees angle of view, whilst this is only delivers 84 degrees angle of view.
