Since making the move from Canon, I bought three FE lenses to replace four Canon lenses. None of my Canon lenses were faster than F/4, so I never considered the gripe about the not having enough fast native glass for my new Sony. My only slight regret was loosing the 200-400 focal length when switching over, but realized I didn't use that focal length that often, and welcomed all the poundage I was not carrying anymore.
Not looking back at my Canon gear, just loving the extra detail, and all the other ground breaking technology that got me to jump to Sony. 5 FPS, 200mm, 800th @5.6 is fast enough for me this day.
