Kaiser Fototechnik 6516 Filter adapter ring, black 52mm-55mm

• • • • If both your lens supports optical image stabilization (OIS) and your camera supports sensor-shift, in-body image stabilization (IBIS), the choice is yours on which one to use, or have both of them work in harmony.
      • Smooth iris support with the latest Canon (2009+), Tamron (SP series 2013+) and Sigma (2016+) lenses.
      • Custom function button (called Focus Hold button) assignable to more than 50 functions, such as Aperture Preview and Eye-AF, on A9, A7 series, A6500 and A6300.
      • Dedicated switch controls in-body image stabilization (IBIS) on Sony cameras equipped with SteadyShot INSIDE.

To clear up any potential confusion, this is NOT Sony Alpha, but Alpa of Switzerland. You will most likely be using the Kern Macro Switar 50mm f/1.8 or f/1.9 apochromat lens on this adapter.

• Both camera-side and lens-side of the adapter are made of brass, precision-machined and plated with chromium.
• Satin surface finish – just like your OEM lens and camera mounts.
• Precise fit and solid connection – lens has no play, gap or wiggling when mounted on adapter and no adjustments are required to fit your lens.
• Designed to reach infinity focus while maintaining the correct registration distance required to maintain optical quality of CRC lenses or lenses with floating elements.
