Hi,

Does anyone have a diagram for the elements of one of these lenses. Yes, I've lost the assembly sequence. This is the APO not the later macro.

I have found this help page but his does not seem to be the same as mine - http://www.pbase.com/pganzel/repair_of_sigma_400mm_f56_apo

Can anyone help please?

Ken.

This is my sketch from taking apart one of these lenses ages ago. I hope it helps.

Mark

Mark,

Many thanks for the diagram, I only wish I had done something like that.
