Wide-angle conversion lens made by OLYMPUS, perfect for underwater photography. - Brand: OLYMPUS - Model: PTWC-01 - Accessories: Lens cap, instruction manual - Type: Underwater wide-angle conversion lens Thank you for viewing. This is an OLYMPUS wide conversion lens for underwater photography. It is attached to the waterproof protector of an underwater camera. The condition is good. I couldn't find any scratches on the lens. The lens is clean as shown in the photos. There are no scratches that would appear in the photos. You can take beautiful wide photos. The paint on the metal part on the side of the main body looks uneven. I'm not sure if it's because it came into contact with seawater, but it's in this condition. I'm trying to lower the price accordingly. Box and cap are also included. This is a current product that is still being sold, and a new one is quite expensive. You can search and see that it is sold for about 55,000 yen. So I think it's a good deal. It is a glass lens. It is heavier than a plastic lens, but it is characterized by being scratch-resistant. Above all, You can take wide-angle photos and videos with a wide field of view. I recommend it. A separately sold step-up ring is included. With this, you can immediately attach it to the waterproof protector of the TG series. I am a beginner on Mercari, so my description may not be perfect, but thank you for your understanding. #UnderwaterPhotography #ForUnderwaterCamera #WideLens #WideAngle #OLYMPUS #Olympus #PriceReduction
