A:Answer Hi,
The size on the lens caps would change depending on the size of the lens you have. On Samsung, it should be shown as a 'diameter symbol'. Specifically for your pancake lens I can recommend you ether the Model: NS-LC67 or the Model: NS-LC62 lens caps. Please know we are always at your service at www.insigniaproducts.com/contact-us or you can also check this at your nearest Best Buy Store.
