Re: [Rollei] Rollinar 3 parallax error

["Simon Greenwood" <mail]

Thanks for your swift response, It appears I correctly fitted the lenses, indeed the 
pictures are pin sharp, which they would not have been if the taking lens was not 
fitted properly.

The problem was clearly with the viewing lens, which whilst accurately focussing 
gave massive parallax error, from what I can see it must have doubled the error 
rather than compensated for it.

could the prism be upside down? (suppose someone unscrewed it to clean the lens 
inside and out)
