Sony A7R II: Evaluating SteadyShot (IBIS) Handheld at 1/20 Second at 25mm

Get Sony A7R II and Zeiss Batis B&H Photo.

See also Sony A7R II: Assessing IBIS at 280mm: Is Handheld Shooting at 42 Megapixels at 1/125 Second Viable?.

A major selling point for some uses is In Body Image Stabilization (IBIS) aka Sony SteadyShot, because image stabilization is brought to every lens mounted on the camera. CaNikon cannot do such a wondrous thing.

I wished to know for my handheld shooting what my odds are with IBIS. And so I evaluated Sony Steady Shot (In Body Image Stabilization aka IBIS) at 1/20 sec handheld using the Zeiss Batis 25mm f/2 Distagon.

IBIS (In Body Image Stabilization) Handheld at 25mm

I used my best technique as described in How to Hold a Camera Steady (Mass Coupling). Tested in 4 variations all handheld, 10 shots each (40 shots total, all shown):

  • IBIS enabled, single shot exposure.
  • IBIS disabled, single shot exposure.
  • IBIS enabled, 2 second self timer.
  • IBIS disabled, 2 second self timer.

The points of interest are:

  • Is 1/20 second realistic for a 25mm lens?
  • How much does IBIS help, and is it consistent?
  • Does IBIS function with the 2-second self timer?
  • Does use of the 2-second self timer help in obtaining sharp shots? (by avoiding the disturbance of pressing the shutter release).
