I am selling a good working condition Canon Tripod Mount Ring C (W) White. This is the tripod collar compatible with the Canon EF 70-300mm f/4-5.6 L IS USM lens and Canon EF 28-300mm f/3/5-5.6 L IS USM lens. By adding a tripod collar to your lens you can achieve better balancing on a tripod. In addition, rotating the camera will now be much easier and faster. This mount ring is used with sign of wear but still in good working condition.

Original price at B&H Photo: $169
