In-Body Image Stabilization IBIS

Pentax has been a pioneer in sensor-shift image stabilization, and the K-3 Mark III benefits from its highly advanced 5-axis in-body image stabilization IBIS system. This system, often referred to as “Shake Reduction II” SR II, provides up to 5.5 stops of shake compensation.

• Benefits for All Lenses: The beauty of IBIS is that it works with any lens mounted on the camera, including older K-mount lenses, prime lenses, and third-party optics that may not have optical stabilization built-in. This dramatically extends the usability of your entire lens collection, allowing you to handhold at slower shutter speeds than would otherwise be possible.
• Low-Light Handholding: The 5.5 stops of compensation means you can potentially shoot handheld at shutter speeds like 1/15th of a second when you might normally need 1/250th of a second for a sharp image, significantly improving low-light performance without resorting to excessively high ISOs.
• Video Stabilization: The IBIS system also effectively stabilizes video footage, reducing camera shake for smoother, more professional-looking clips.
• Other SR II Applications: Beyond just shake reduction, the SR II system enables several other useful features:
  • Pixel Shift Resolution: As discussed, this relies on precise sensor shifts.
  • AA Filter Simulator: This unique feature allows you to simulate the effect of an optical anti-aliasing filter to suppress moiré patterns, or effectively turn it off for maximum sharpness, directly in-camera. This offers flexibility depending on the subject matter.
  • Composition Adjustment: Allows for minor shifting of the image sensor for precise composition adjustments without moving the tripod, useful for macro or architectural photography.
  • Astrotracer with optional GPS unit: When paired with the O-GPS1 unit, the SR II system tracks celestial bodies, allowing for longer exposures of stars and nebulae without star trails. This is a niche but incredibly powerful feature for astrophotographers.
