Question about Sigma AF 28-200 Lens
I had my older 28-200 3.8-5.6 AF-D lens in pieces to clean mould from the inner lens surfaces..unfortunately the tray holding the components ,all of which had been placed in sequence, was knocked upsetting the contents. What I would like would be a diagram showing the schematics of the optics. I can get close, but not close enough!
I have the same lens. It got dropped into sea water. I rewashed in freshwater and took the lens apart after it dried, to clean the water spots. I was sent a diagram from Tamron but it is not high resolution file and is hard to make out the parts. I have posted it FYI:
I am still searching for a better diagram. Do you have any leads? This one I've just posted came right from Tamron. I can't figure why they would fax something so illegible but it may help you? Does anyone have a high resolution diagram?

The front elments is a sealed unit so I think it must be the back elements you need to no how the fit what size filter is un you lens is a hyperzoom .
