If you have too many lenses to keep track of and want to be able to identify them quickly Field Made Co has a unique sticker set that will make it easy to identify your glass from the lens cap. This looks like a very useful product and it would be great if stickers like these were included with lenses in the future. If you want to get your own set they are available for X mount here. Field Made Co also makes a set for the Fujifilm GFX which you can find here but they are not sold as a package yet.
