Hi guys,
I have recently bought a Linos Inspec.x L 105mm macro lens from China. This is an industrial lens, basically the same as Rodenstock macro 105mm float, but with the floating element set at a rigid 1:3 scale.
The price was excellent, the delivery took ages, but now, when it finally arrived I do not know if I should even keep it.
The glass looks clean but there is a lot of white spots on internal metallic surfaces. At first I thought that would be a case of "schneideritis" and just black paint flaking, however there are also white spots on silver internal rings - is it a lot of internal dust or fungus?
I have never had any such dusty/fungi lenses and I am wondering if I should send it back or try to clean it somehow. Is it even doable, considering how advanced this lens' construction is.
Any help appreciated.
