[0.04 lb] How I use the Lens Flipper: - I bought this lens for use with my Sony FE lenses. It allows me to have a total of 3 lenses on hand with my Sony Alpha a9 body to use. I actually bought the Canon EF version of this LensFlipper, mounting L-glass lenses that are usually on the heavier side and this thing has NEVER disappointed me. What I like about the Lens Flipper: - I do NOT like the idea of lugging around 2 camera bodies. (that sounds expensive and cumbersome). Being able to swap lenses and keep all my shots on the same card with an accurate chronological order kept sounds much more ideal to me. This LensFlipper allows me to perform quickly where speed is essential, especially since I prefer to shoot with prime lenses. With my lightweight Sony FE lenses, this is working out even better than with my Canon lenses. I work can be anything from events to portraits and this helps for both. A strap is provided and it works for me. What I don't like about the Lens Flipper: - Absolutely nothing. Well done, GoWing. = Overall: - This a very nifty, innovative invention. If you're using it to hold smaller, lighter lenses like I do, it's such a relief on your shoulders.

[4.7 x 4 x 0.3"] For all of those times you want to carry one lens in addition to the one on your body, but don't want to lug around another bag, the ingenious design of this device is just what you need. Your additional lens is always right at your side and easy to swap quickly, minimizing the potential for damage or dust accumulation on your lenses or inside your camera body. Very easy to use and convenient.

[4.7 x 4 x 0.3"] Solved the problem of not having enough hands to change lenses back and forth, particularly where your needs keep changing from one minute to the next. Others had cautioned about mixing up the buttons and accidentally releasing the wrong lens--but I had no trouble with this (but I am very cautious in handling my lenses). I just came back from visiting 3 National Parks and found this product to be a tremendous help switching between my Canon EFS 10-22 and my Canon EF 24-70mm f/2.8L II USM. I am anxious to check out the belt clip which GoWing has had in redesign for some time (disappointed that GoWing has taken so long on that).

[4.7 x 4 x 0.3"] A must have, avoids the worry of dropping a lens. Definitely will always have this with me when I shoot.

[0.04 lb] I am a current user of the GoWing Lens Flipper for Canon EF-Mount lenses, and now that I have the Canon R3, the GoWing Flipper for RF-mount lenses allows easy carrying of additional lighter RF lenses such as the Canons' RF16mm, 35mm, and other small RF lenses. This gives me the flexibility to quickly interchange lenses on the go without fumbling through a camera bag. Highly recommended for Canon users.

[4.7 x 4 x 0.3"] This thing is used to carry one or two lenses in the lightest way possible. It's comfy, despite the narrow, lightweight strap, because E-mount lenses aren't very heavy. I wouldn't try it with the 70-200, though. The middle part is plastic and might break off, not to mention that at that weight, the strap would probably start cutting into your shoulder. For all the other lenses, though, it's the lightest, most comfortable way to carry them. It affords them zero protection, but if you're reasonably careful, you'll save a lot of weight, including the weight of the bag. And it makes lens changes super easy! There's a plastic shield in the middle that keeps dirt out of the back ends of the lenses while they're mounted on the carrier.

[0.04 lb] Genius idea! I'm so glad they finally made one for Fuji.

[4.7 x 4 x 0.3"] If you only want to carry one extra lens, this makes doing that and changing lenses less hassle. It is light and not bulky. One had holding teh camera, another the lens, and you are done.

[4.7 x 4 x 0.3"] Great product. Simple design and easy to use. I now have two of them in my bag to allow me to swap 4 lenses!

[4.7 x 4 x 0.3"] It is fine and value for money
