New 52mm to 49mm Step-Down Ring Adapter The 52-49mm ring
adapter easily screws onto the front of any 52mm lens, and converts the
thread size of your lens to the thread size of any other 49mm accessory
(such as UV CPL ND filters, hoods, flashes and lens converters).
Extremely
solid and lightweight. Specifically designed for your camera for a
tight and secure fit. No wobbling or cross-threading.
Your
camera's lens thread size will be marked somewhere on the lens barrel.
This number is always preceded by a "Ø" (diameter) symbol. For example:
Ø58 = 58mm lens thread size. This number can also often be found printed
on the back side of your lens cap.
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! Accessory only. Lens and UV Filter not included.
Made of high quality anodized black aluminum (metal). Color: Black.
