What does IBIS mean in UNCLASSIFIED

IBIS stands for In Body Image Stabilisation. It is a technology that helps reduce camera shake or vibration when taking a photograph by using the image sensor to detect any movement and apply the appropriate level of correction.

When the shutter button is pressed, the image sensor detects any movement or hand tremor, then compensates for this with corrective electronic signals sent to the lens element. This helps to keep the photographer's subject sharp and well-defined.

Yes, there are a few potential downsides when using an IBIS system on a digital camera. These include increased battery consumption and potential noise from the corrective signals being sent to the lens elements. Additionally, some lenses may not be compatible with certain cameras that have an IBIS system installed.

Investing in an IBIS system can be beneficial if you find yourself often taking photos in difficult lighting conditions or needing to use slower shutter speeds due to limited light sources. However, it is important to research which systems and models your lenses are compatible with prior to making a purchase decision.

Aside from countering camera shake and helping photographers take clear, detailed images, using an allocated in-body stabilised system can also benefit performance when shooting videos as it will help reduce possible motion blur as well as stabilising overall video footage quality.
