[rollei_list] Re: Spinning front taking lens

I'm not sure that I understand this lens spinning property.

I have always been told that in lenses that consist of more than one element, each element has a specific orientation with the other elements in the group. I was told that if I took a lens apart, I should mark each elements orientation so that it could be reassembled with each element oriented properly with respect to the other elements.

So a spinning element makes no sense to me.
