QuoteOne thing I like to note, is the burst shooting rate has increased greatly. Before I could only shoot 4 photos in High Speed Mode JPG or RAW, then I would hit the Canon "slowdown" buffer. But now I can hit 7-8 in RAW mode before I get a slowdown, and more than 30 with JPG-L. I stopped after 30 with JPG, it could go more but I don't want to use up actuations. All testing done in high speed mode, viewfinder mode.
My burst shooting rate slows down when I have "Chromatic Aberration Correction" enabled. It does not improve with Magic Lantern installed. Have you possibly disabled it without knowing?
