Meopta Meostigmat 1/50mm

[hinnerker]

Thank you very much for you prompt reply and warning , Henry ! One can never be too careful with lenses . I did try 3 times , once opting to reverse the 3-rd element, but it could not fit it's bed properly. All elements are pushed carefully all the way down. Would it be too much to ask for a schematics - like drawing ? Something like : [)(] [)[)[) ) .
Could the lower sharpness be due the fact that the lens was not in a perfect optical shape - some fungus/dirt cleaning was needed ?
Thanks again ,

The schematic of the front tube part of the 1/50 Meostigmat is = a single convex/plan - Element, followed by a second single element, front is convex/ rearside is concave and on third position you will find the cemented group.. 1. glas bigger then second one...near plan/convex and small side goes first into the tube.

Pos. of front elements in front housing:
1. ___2.__ 3.
(| -- (( -- |?)... thats the way the lens elements take place in the housing. First element is the last element during reassembling procedure. (Question mark means thats a cemented group, where i dont know the "inner" curves)

Keep in mind, that there must be a small spacer/shim/washer on the back part of element No.2, please dont forget to establish this spacer !!!

Cheers
Henry
