I am not too sure that “shutter speed stability” is the term you are looking for. This is the first time I have heard it used. If when shooting handheld, and you have a static target/subject, relatively slow shutter speed (usually slower than 1/120-1/80), and a longer focal length IBIS, or ILIS (IS/OS/VR) is going to be a great help.The greatest benefit will be found with handheld landscapes, or portraits. When it comes to moving targets/subjects a shutter speed, direction of movement relative to the photographer, and camera handling techniques are going to be far more beneficial than any mechanical stabilization. The only time stabilization can help with a moving target/subject is when the movement is directly away, or towards the photographer. When shooting with a panning motion the camera is stabilized by the inertia imparted to the camera system by the lateral movement of the camera tracking the target. -- Regards, Savageduck |

Since you shot those ducks at 1/2000 you could probably have managed without IS. I usually turn off IR for any critter tracking, be sure to leave uv on. So I made an obvious typo. as it slows down the tracking a tad. actually it doesn't, since stabilization is an independent system which keeps the subject steady in the frame, making it *easier* for focus tracking to work. it takes time to stabilize. This image would not be the same with stabilization. https://www.dropbox.com/s/ji4rs200lj32o9o/20180319_bIRDS%20wakotahatchee_0627.jpg?dl=0 The shutter speed stability depends on the user's individual hand stability, speed of the critter, and the focal length of the lens. the shutter speed stability depends on the shutter mechanism. -- PeterN |
