CA is usually red one edge, blue on the other edge. Purple edging is usually sensor bloom from the camera.
Would you mind explaining what you just said...
In any case on the same camera used with letus you don't see it while with blade you do. I know it has something to do with amounts of light and apperture level of the lens but ever since the LEX came out the letus adapters stopped causing that. everything I say is probably BU%$##T so please explain to me what I'm seeing.
