The OP/TECH USA Double Lens Mount Cap allows you to securely lock two Micro 4/3 lenses together. This is a huge space saver, as it enables the photographer to keep gear protected in a compact fashion.

This Double Lens Mount Cap is designed with an O-ring seal which creates a positive contact with the full perimeter of the lens mount area, locking out dust and moisture. It also offers a tighter friction fit over traditional caps that come with the lens, providing better protection to the lens mount area. This ensures that the cap is securely held in place while in storage or transit.

This item is made in the USA.

Q: 1. Will this fit on a Joby Pro Sling Strap?

A: Looks like you got several good answers. I'll just add that the holster will take a strap up to about 1 1/4 wide. The loop is fixed so the strap has to come apart to thread it through.

Q: 2. I have lenses for a Sony a6000. The lens diameters indicate I buy the micro size, but the hood diameters suggest the mini size. Which measurement should I go by?

A: Since I do not have the camera, I cannot say exactly, but I think it depends on how lose you want the hat to fit. They are supposed to stretch onto the lens, so you want to buy one that is smaller than the lens diameter. But I know myself that they can be hard to put on if they are too snug and require too much stretching. But then they stay on better, of course, so it IS hard to tell. I think I'd go with the smaller one, especially if the lens is shallow - i.e. not very long. If the hat is too big and just kind of loosely holding on, it will probably be falling off if the lens isn't very long. Just MHO.

Q: 3. Does this fit the Canon 70-200mm 2.8 IS II with the lens hood attached in reverse? How are the filters protected?

A: I sold this 70-200 lens (a less hefty non f/2.8 version) way back. I doubt that the heavy f/2.8 would fit friction-free in this when the huge hood (for the f2.8 II) is also attached backward. Hope this help

Q: 4. Where is the 21.5-25" and 23-46" lengths for small and medium measured? Maybe superimposing on the model person with the strap will be clearer.

A: Being that the adjustments are made at the bottom of the straps where it meets the strap lugs on the camera, the measurement is most likely taken from that point up to the neoprene pads that rest on the shoulders.

Q: 7. is this the right size for a Leica Q? or the mini?

A: I use this item on my Leica Summilux-M 1.4 as I was always loosing the Leica Cap...not to say I haven't lost a Hood Hat, but they stay with me longer. I just tried it on my friends Q and it fits. A little tight...requires both hands...but the next size up may be to big. Make lots of images. Best C
