The K&F Phone Mount Adapter for 67 mm Lens Filter is a clip-style smartphone holder that secures to a 67 mm filter thread or adapter ring to align a phone camera with a photographic or spotting scope lens.

Advantages

This adapter provides a straightforward mechanical connection between a smartphone and a 67 mm threaded lens or adapter ring, ensuring reliable centering and consistent framing. Its clip-style design allows quick attachment and removal, while the holder accommodates typical smartphone sizes and camera positions. The accessory preserves the optical characteristics of the lens or scope and enables use of the phone's native camera app and controls for exposure and focus adjustment.

How to use

Attach the adapter clip to a 67 mm filter thread or an appropriate step-up/step-down adapter ring screwed onto the lens or scope. Place the smartphone in the holder and adjust its position so the phone camera lens aligns with the optical axis of the attached lens or scope. Tighten any adjustment screws or clamps to secure the phone in place, then use the phone's camera app to set focus and exposure. For best results, fine-tune alignment while viewing the live preview and stabilize the optical instrument or tripod before capturing images or video.

Usage recommendations

Ensure the 67 mm thread on your lens or adapter ring is clean and free of damage before mounting. Use a tripod or stable support for the lens or scope to reduce vibration and improve image sharpness. When aligning the phone camera, work in live view and make small lateral and vertical adjustments until the image is centered; lock the holder once alignment is achieved. If your smartphone has multiple rear lenses, position the adapter to match the primary camera you intend to use.
