HC 150mm : two versions?

[Thomas73]

Hi all,

I am wondering if there are two versions of the HC 150/3.2. Indeed, I see sometimes in designation '150n' or '150N' ('n' like 'new'?). Was there an upgrade of this lens since the H system release?

By the way, what is the quality of this lens?

Thanks for your replies.

Ok, thanks for your replies.

Is there a way to identify each version (instead of the 'N' designation) : year of manufacturing (through the S/N)?
