I understand that radarlock frames will only accept radarlock lenses. My question is concerning asian fit. Is there a difference between lenses for the asian fit frames or is the difference merely in the nose piece, thus rendering the lenses cross compatible across the frame variants? Essentially meaning can I put a lens from an asian fit radarlock frame into a non-asian fit radarlock frame?
My understanding is that the for the original Radar and Radarlock, the Asian fit frames are exactly the same as the regular versions (just the nose bombs are different). For the Radar EV, I believe the lens and frames are actually different for Asian fit.
