In-Body Image Stabilization
In-Body Image Stabilization works in a similar manner to In-Lens stabilization in that it has a moving element to counteract any camera movement. The image sensor moves around to compensate rather than a lens element.
The main benefit of IBIS is that it works with all lenses, meaning that at least in theory all of your old lenses that are able to attach to your IBIS-equipped camera body now have stabilization.
One down-side to IBIS is that it tends to work better only at shorter focal lengths. On longer telephoto lenses, like a 500mm, the sensor shifting mechanism isn’t able to move enough to provide adequate shake compensation.
Luckily a lot of the newer mirrorless models that feature IBIS are also able to combine with some lens models so that their shake reduction system work in tandem. For example the Sony A7RIII, as well as the Canon R5.
Do I need ANY Image Stabilization Technology?
Like anything in photography…it depends.
If you are primarily a landscape photographer shooting in low-light conditions then this entire article may be of little use to you. In most cases, you are going to want perfectly still stabilization for longer exposures. Landscape photographers are more often than not shooting in extremely low-light conditions and exposures can be many seconds if not longer. In this case, a tripod is still your only option for real success.
Also, for those of you wondering, there aren’t benefits from using image stabilization technology and a tripod in concert. In fact, quite the opposite. When using IS combined with a tripod you are essentially creating a feedback loop where the camera detects its own vibrations as a movement. Because of this, when using a tripod you’ll want to be certain to turn off any image stabilization.
I’d encourage you to think about this topic more, and to apply it to your own photography. Really, no matter how good your gear is, if the camera isn’t stabilized properly you’ll never really get to see just how good it is. When a tripod isn’t available or convenient, the advancements made with image stabilization technology can be a game changer!
