If you're all about manually focusing then this purchase is an absolute no-brainer. TAAB brings a focus tab to pretty much any lens and if you avoid Auto-Focus like the plague you're going to want a TAAB on each and every one of your lenses. 

TAAB is made from a durable, high-grade neoprene that comes in three sizes to fit everything from a smaller mirrorless-sized barrel to a traditionally-sized DSLR lens. Not only do you get great control over your focus ring, it gives you a visual guide to let you know your focus point so you can nail that shot every time.
