Your camera s lens thread size will be marked somewhere on the lens barrel or printed underneath your lens cap. This number is always preceded by a "Ø" (diameter) symbol. For example: Ø52 = 52mm lens thread size. Compatible with the CANON EOS M Compact Camera. EF-M 18-55mm IS STM zoom Lens. Also compatible with the PENTAX (K-30 K-50 K-5 K-5 II) DSLR Cameras. 18-55mm F3.5-5.6 AL zoom Lens. We make it possible for you to use a lens cap while you have our lens hood mounted(lens cap not included). Tulip shape design (also known as "flower" or "petal" shape) allows for greater versatility. Perfect for standard or zoom lenses. Lens hoods also have the added benefit of providing extra protection to your lens from accidental bumps or scratches.
