I suppose we all end up owning lenses where we simply don’t know what optical formula is in use.

My two most recent purchases are a Meyer-Optik Görlitz Oreston 50mm f/1.8 and a Pentacon/Meyer-Optik Görlitz Orestegor 300mm F/4 (still in transit).

I guess I'll never know the optical formulas for these.

I think that we can find the optical formulas Eric - I should try and see how I go.  The Orestegor 300/4.0 is quite a large heavy lens.  It reeks build quality but I think it is really a lens for a large stationery tripod - probably waiting patiently fro a certain bird to land on a prefocused branch .....
