Original Olympus lens cap, 58 mm, fit the 2 kit lenses and the Zuiko 70 -300er Tele. He is working properly, keeps the lens prima and is solid. I got my left lying on a hiking trip and had no desire another 1.5 hours running back. Since I was very glad that I was able to buy back the original cover here. Whether this plastic part .... well worth the price. You pay more for it again well to have a lens cover, as the real value of the cover. I was glad of it and therefore, 5 Star.
