Step-up Adapter Ring Hoya 67→86mm for Square Holder SQ100

Adapter ring that converts a 67 mm lens filter thread to 86 mm, allowing the HOYA Sq100 square filter holder system to be mounted on lenses with a 67 mm front thread. The ring is intended for use with the SQ100 holder and the 86 mm geared adapter included in the SQ100 Holder Kit; the Holder Kit itself is sold separately.

Advantages

The adapter ring enables compatibility between a 67 mm lens and the HOYA SQ100 system without altering the lens. It is lightweight, metal-threaded for secure mounting, and preserves access to the lens filter thread so standard 67 mm filters can still be used with a step-up configuration.

Suitable for

• Photographers who use the HOYA SQ100 square filter holder and own lenses with a 67 mm filter thread
• Landscape and architectural photography workflows that require graduated or solid square filters
• Users who want to adapt 86 mm accessories or the SQ100 holder to smaller lenses

How to use

Check the filter thread size of your lens (usually printed on the back of the lens cap or in the lens manual). Screw the 67→86 mm adapter ring onto the lens filter thread. Attach the 86–86 mm geared adapter from the HOYA Sq100 Holder Kit to the SQ100 holder, then mount the adapter ring onto the geared adapter so the holder is secured to the lens. Ensure all parts are tightened but avoid over-torquing.

Usage recommendations

Use this adapter ring together with the HOYA Sq100 Holder Kit (geared adapters included in the kit) and check that the geared adapter matches the ring before mounting. Keep threads clean and dry to avoid cross-threading.
