I shoot quite a bit of stuff with 35,50, and 85 at 1.4 and 135 f2 and I'm usually outside using high speed sync so shutter speeds are pretty high to get rid of ambient. June 30, 2018 By JimK 5 Comments. still does not explain why while A7R (w/ 55mm, body mounted) is noticeably affected by relatively slow moving shutter blade (1/160 x-sync), A7 (w/ 55mm, body mounted) is not with faster moving shutter blade (1/250 x-sync, EFCS OFF)… unless the body material itself makes some difference (plastic front in A7 vs metal front plate in A7R) ? I keep it on, it's not really a big deal. Fred thanks for reply. From what I've heard it is a quieter sound and potentially less vibration.

Enabling EFCS on Sony Mirrorless Cameras. 5.3. I decided to start with what should be a pretty easy test, so I used a 55mm lens. Panos are usually shot at high aperture (f/8 or f/11) so to get 1/1000s or faster would be rare. I mostly shoot portraits at 1/200 or faster so maybe I should just keep it off?
