Honest question: Who uses a 'by wire' aperture ring on a fully electronic lens, for stills?
And a follow up, why could you not use the multi-function ring for that?
Exactly. If you have to have an aperture ring for video, what Canon have done is a much cleaner design than adding a clicky mode and a slider to switch between that and clickless, like Sony.
For those who don’t know: the purpose of stepless aperture rings on video lenses was traditonally so that you could alter exposure in a single take. You can’t use shutter speed to do that because many people think motion looks odd if it isn’t at “180°” (half the duration of each frame, or 1/48s for 24p). And, back in the day, every frame had to be shot at the same ISO because it was on film.
These days you could (in theory) alter ISO steplessly but it seems old habits die hard in the cinema world.
I have to say, when I saw the aperture ring at the start of Gordon Laing’s video I thought this would mean a hard “don’t buy” for me. I shoot stills, and I don’t like aperture rings and hard 1950s-style dials with numbers on them in general. I was relieved to hear from him later that the ring was inoperative in stills mode, so I don’t need to worry where it’s set or set it to A if I’m using other than Av mode.
