Hello all,
R7 and RF 100-500mm owner here looking to see if there's a way to prevent the lens from automatically turning off it's stabilization in video mode when mounted on a tripod, as it seems to do. I tested this with all three IS modes, at all levels of digital stabilization, and even mounted the camera body itself to the tripod instead of to the mount but it behaved the same with every condition.
Handheld, the stabilization works as one would expect, but about between 3-10 seconds after I mount it to a tripod (I use a quick attach adapter) it will seemingly shut off and any kind of tap, gentle movement, or even just half pressing the record button results in massive amounts of jitter (whether it’s recording or not changes nothing). BEFORE those 3-10 seconds however, the same tapping etc. movements are substantially dampened or even eliminated as presumably the IS is still active.
My previous lens was an EF 100-400ii with the 1.4x extender, and that did not suffer from jitter either at similar focal lengths, probably because the stabilizer was constantly running. Is there anyway to force the RF 100-500 to stay stabilized while on the same tripod as well, whether in-camera or some sort of lens setting? As of right now the thing is almost completely useless for tripod birding videos, and a heavier tripod is not an option due to being used on hikes.
