Canon 67C Macrolite Adapter

Mounted this on my EF 100mm and the ML-3 sits rock solid—no wobble when I'm twisting focus rings. The 67mm threading matches perfectly, so I'm finally getting even light on close-ups without hunting for adapters.

The threading is smooth and sits perfectly on my 100mm macro lens, so attaching the MT-24EX takes seconds instead of fumbling around. It's a simple piece of plastic but the fit feels rock-solid, exactly what I needed to get my twin flashes working.

Took my macro flash photography up a notch by making it compatible with my 100mm lens. The 67mm adapter ring screws on securely and doesn't add any extra bulk.
