Beamshot of Convoy AR Green vs UCL AR Purple. Picture shot in RAW format with DSLR. Manual setting & WB @ 5000K. Both light and camera on tripod to minimize fluctuation. I noticed something that’s not frequently mentioned, that changing lenses not only affects Duv, but also shifts CCT about 50-100.
I hope you could see the UCL purple lens makes the scene more yellowish (attention to the white wall @ middle of the picture) but please keep in mind photography tends to exaggerate difference IMHO/experience. In real life use, I could see this difference against a white wall but it’s not as severe as this picture would indicate, and much harder to see when shining on darker subjects with colors instead of a white wall.
Even though this is comparison against a UCL AR Purple, not original Convoy AR Purple lens (I couldn’t find one to buy), I am glad that all my Convoy lenses have green reflection. :innocent: It does magically remove yellow tint from a scene.
