Just acquired this Mirror lens for a reasonably cheap price, I know they are soft and hard to focus but I like the concept of long Focal Length and low price. The Lens has all 4 Filters and original case.
My problem is Fungus on front lens.
Has anyone had experience in pulling one of these down.
These appear to be different from the " Normal " Mirror Lenses as they are Solid Glass with no air gaps in the lens.
I have cleaned the rear and was pretty straight forward but the Front is causing some problems.
I can see what needs to be done it's just a problem of how without doing damage.
I do also have a Makinon 500 mm F:8 and a Tokina 500 mm F:8 both cleaned with no problems.
Any advice would be appreciated.
