    GPO Passion ED 10 x 32 Review.

    Dipperdapper post 16, In the table I wrote for the GPO 8x32 88% transmission at 500 nm and 90,2% at 550 nm (I just checked 20 seconds ago and nobody changed it, so it still must be there). Gijs van Ginkel

    GPO Passion ED 10 x 32 Review.

    Dipperdapper, post 13, I find Lee a very nice fellow, but I did not refer to a GPO testreport on the WEB-site of House of Outdoor by Lee , but on a test report by me and my colleagues. That test report was focussed on 30/32 mm binoculars, new and old ones. Gijs van Ginkel

    GPO Passion ED 10 x 32 Review.

    Imans66, post 9, The GPO Passion ED 8x32 we recently have investigated did not have any play in de focussing wheel when we investigated it and it stil does not have it after a few months of use. Perhaps your sample needs repair. Gijs van Ginkel
