35mm Adapter - Tests
ran a test of the adapter before epoxying and final assembly, just to check measurements and such.
this was done with the gg off and not rotating.
there is some chromatic abberation visible, which i am unclear to what is causing it. either the macro (which isnt an achromat) or the fact that there isnt a fresnel in front of the gg. i'll try both and see what helps.
the optura was place at two feet away and the test chart at three and three quarter feet away. lighting was just a 250 watt floodlight.
movie availible here (note: quicktime 7 required) 640x480 @ 2.3MB
