Is IBIS a must for for Underwater Video? in Video Gear and Technique Posted September 10 I've done a couple of dives with Sony a7s3 or a1 with a 90mm. Even with darn good buoyancy control and a balanced rig handheld keeper footage is in the in the range of a 1 sec out of a couple minutes and then, sometimes never. I learned to really lighten my grip on the housing to minimize to minimize muscle twitches. If I do macro or even quasi macro shots I try and shoot at 120fps which can have a nice feel when slowed down. Or if I have the a1 and my 24-70mm kit (Which is my go to arraignment) and a macro opportunity shows up I'll go to 8K and work it in post but its only 30fps so still needs to be steady with spot auto focus. I also rely on stabilization in my post environment which starts in FCPX. Someday I'll get on board with Resolve for working color and grain.
