I bought a 3-9X 50 Panorama AO IR Map6a Ret, And have the issues mentioned in the OP. Slightest movement and i lose the picture, black edges , Distortion the works !! I also have a Bushnell Legend which i have no issues with and is nice and clear.
Have tried a few things to work out the Hawke but nothing seems to change it which is a shame because it is clear when i finally get my head set right !! and the Map6 ret i really like.
Have tried the Hawke on my S200 & the Superten but still get the blurry image / Black edges . Time to sell it i think and try a MTC methinks !!
