The story of this mug: I still remember the day when I saw this mug decades ago. I was a young photography enthusiast and just graduated from university, chasing those fantastic lens and cameras but couldn’t afford a good one. One day when I visited a friend, I saw a EF24-105 lens at his desk, I was excited and wanted to take a look at it carefully. So I picked it up and tuned it over before my friend warning me. No surprise, the water spilled out everywhere. I was sooo embarrassed then realized this was a mug, not a lens. Years later, when I started Amazon business, this mug is the first product on my list. I worked with team, optimized it and made it more “real”, featured with all hallmarks of a classical EF24-105mm f/2.8G lens. And 1:1 replicated the lens, including image stabilization switch, autofocus switch, distance information window and technical information like aperture size. Also, some details are updated too to make it more functional. For example, the focus dials are made of high-grip rubber for user to keep a firm grip. Until now, I always put it on my desk, see if someone will do the same as I did. Hope you can enjoy the joke too, and have fun. Please Note: Do not put into the microwave as it contains metal parts. Do not put it into the dishwasher.
