Because of extremely conflicting reviews of this angle viewfinder I was not sure if I should spend the premium price for it. Have it but then done. My Opinion: It was really like that! Properly secured, metal guide, does not shake, easily and accurately mounted. Flawless optical function blameless, No problems with focus, be adjusted not too light by accidental contact Optics properly when operated with and without glasses
Glad I do not have to bother rickety Billigteil.
4 stars because of the following: OK, there are some lenses in the device and the housing is perfectly ... ... But: the price is quite high compared to eg lenses. No alternative, at least for me =>: On the other hand.
