Use the low-profile LockPort USB 2.0 Adapter Baseplate for Canon 5D Mark III from LockCircle to protect the USB port of your camera. 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. The "loose" design of the adapter does not lock the USB cable to the camera, so any accidental tug on the cable will not result in your camera crashing to the ground.

This adapter features gold-plated contacts that provide an extremely reliable connection, and its low-profile design enables the LockPort to work with most rigs, heads, sliding plates, and other support devices without obstructing the battery door.

Related Questions and Answers

Q: 1. Does the SmallRig CCC2271 make it possible to mount a camera on an Arca-Swiss type quick-release tripod head in a vertical/portrait orientation like an L-bracket does?

A: With the SmallRig Camera Cage for Canon 5D Mark III or 5D Mark IV, one could mount a tripod plate (such as an Arca-Swiss type plate) on the right or left side and then position the camera vertically on a tripod head.

Q: 2. If the surface finish black anodize or black paint? Or powder coat?

A: The L Bracket appears to be anodized. I also own a Really Right Stuff L Bracket for my Canon 5D and purchased the Sunwayfoto bracket for my Canon Mark III. I am as pleased with the quality of the Sunwayfoto as with the Really Right Stuff L Bracket and at half the price! Hope this helps

Q: 3. Would this be useful for astrophotography?

A: Yes, magnifying the display to view and compose images would definitely be beneficial.

Q: 4. Will the LOCKCIRCLE LockPort adapter baseplate work with a Manfrotto 410PL Quick Release Plate?

A: According to Lockcircle, this plate will work with any quick release plate on the market.

Q: 5. Is this cage compatible with the SmallRig HDMI Cable Clamp 1693? I think I see it on photo #5.

A: Yes, this cage is compatible with SmallRig 1693. https://bhpho.to/2RGmOXE

Q: 6. Can be used with a Canon 5D Mark ii?

A: We're afraid not. This is a form fitting cage for the 5D Mark IV and III, which have different dimensions from the Mark II. Instead we recommend a universal option like the SmallRig 2127 Quick Release VersaFrame Half Cage (Medium) for the 5D Mark II, BH #SM2127B. https://bhpho.to/2O7riSj

Q: 7. Will it work with 6 NiMH rechargeable batteries?

A: Yes the Canon BG-E11 Battery Grip can also be used with 6 AA batteries. You can use disposable or rechargeable batteries. However in my experience, you gain longer running time using 2 Canon LP-E6 or LP-E6n batteries.

Q: 8. Is this bracket compatible with a canon 5D Mark II?

A: Unfortunately not. These camera bodies have slightly different designs.

Q: 9. What is an ARCA-type platform I keep seeing this in the responses. I have a Manfrotto 488RC4 ball head but there are no markings about it being an ARCA-type. How do you tell?

A: ARCA is a universal type plate, well except for Manfrotto. Check out the ARCA-Swiss products to get a better idea of what they look like. In order to use my new L Bracket with the ARCA type plate I had to use a different brand ballhead, since my Manfrotto does not use the ARCA type plate.

Q: 10. 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.
