This is the release button L silver -Irregular Edition- by Nanigashi. I am selling this because I plan to purchase a different size of the same product. From the website below: nanigashi -Irregular Edition- -Irregular Edition- was created with a different approach, a different production method, and a different way of thinking than usual. This is an irregular product that was planned thinking this year was the 10th anniversary of the launch of nanigashi, but it turned out to be only 9 years. Well, it doesn't matter if it's not the 10th anniversary, so I went ahead with it. This product is the Irregular Edition of the release button L. After applying silver paint to a button made by machining brass, the nanigashi signature is engraved. The brass of the base material is visible in the engraved part, and the expression of the signature changes with use. The top surface of the button has a gently concave curved surface, so your finger naturally fits there, and the side has knurling, making it easier to turn the screw when attaching it. Also, an O-ring is included to be installed between the button and the camera, making it difficult for the screw to loosen and the button to come off. *Depending on the model, it may be difficult to screw in when attaching. In that case, please screw it in while pushing it slightly. If you still cannot attach it, please remove the O-ring and use it. Due to manufacturing reasons, the logo may not be facing forward even when attached to the camera, please understand.
