This sturdy aluminum plate and its arm hold a 90° mini-USB to USB adapter securely in place, preventing the USB port from sustaining any accidental damage from impact or pressure.

Related Questions and Answers

Q: 1. can the sunwayfoto bracket be left on or have an area to attach the strap mounting adapter when using a Black Rapid camera strap?

A: Technically, yes, but be careful. I currently have a 5D III, the Sunway bracket and a Black Rapid strap that comes with the screw-in attachment to the base. The Sunway Bracket has a separate threaded hole that fits the Black Rapid screw, right beside the bracket mounting screw. However, you have to remove it if you wish to switch to landscape orientation with a BR strap that lacks the tripod mount (like mine). That sort of defeats the purpose of the bracket, which is speed of orientation shift. If you use a bigger strap such as the Carry Speed, with the integrated tripod mount, you are good to go. Check to see if your type of BR strap has this feature.

Q: 7. Can you use a non-arca-swiss QR plate for mounting cage to a manfrotto head? Specifically, I want to attach a 410PL QR plate.

Q: 9. Will this fit my Sirui Ball Head?

A: It depends. If your ball head has an ARCA-type platform, then yes, it should. But to be sure, if it were me, I'd call B&H customer service and ask. They are VERY knowledgeable and can probably tell you for sure.

Q: 10. I have a non canon battery grip and the biggest issue is with the connectiobns to my 5d m3 r sometimes having issues. For example starting to shoot and no power, having to tighten the attachment screw or just working it around a little. Very Frustrating. With the Canon brand grip is this an issue or does it consistently keep a god connection between the camera and battery grip? Price is high but I can't continue too use a battery grip that is inconsistent providing a solid connection to my 5d.

A: The Canon grip should work seamlessly on the 5D3 without any issues.
