The 82-95mm ring adapter easily screws onto the front of any 82mm lens and converts the thread size of your lens to the thread size of any 95mm accessory such as filters, hoods, flashes, and lens converters. Made of high quality anodized black aluminum (metal). Color: Black. Extremely solid and lightweight. Specifically designed for your camera for a tight and secure fit. No wobbling or cross-threading. The first number is always the lens thread size, the second number is the filter size of the accessory. If the first number is bigger, it's a step-down ring. If the first number is smaller, it's a step-up. A must-have accessory to unlock the full potential of your camera! NOTE: PLEASE VERIFY YOUR CAMERA'S LENS THREAD SIZE BEFORE ORDERING. This kit is compatible with 82MM lenses only. Lens sizes vary regardless of camera brand or model.
