LockCircle announces the end of the HDMI problem – the LockPort5

by planetMitch3 Comments

Our friends (and sponsors) at LockCircle have announced a new HDMI port solution for HDSLR rigs – solving the problem where the HDMI cable disconnects from the camera without warning.


The LockPort5 is a new product developed to help avoid damaging your Canon EOS 5D Mark II camera port. The mini HDMI camera port is very “expensive to repair” if damaged!

The LockPort5 protects definitely the fragile output on your camera from tough production abuse with a rock solid clamp and a smart mini to full-size HDMI adapter.

The LockPort5 adapter is designed to fit easily the popular RedRock Micro DSLR Baseplate using the original screws and soft adhesive pads. Ready in 3 minutes!

The LockPort5 safely secures a 90° FRONT/REAR mini HDMI to full-size HDMI adapter, protecting forever the “expensive to repair” mini HDMI camera port.

The adapter has gold plated contacts, the full-size female output allows you to use stronger standard HDMI cables, you can purchase everywhere!

Standard size HDMI plugs locks securely in the socket – no signal loss!

The LockPort5 was designed last year by a well recognized Italian-Australian digital cinematographer shooting massive film/tv-series productions with 5D cameras. The LockPort5 was the smart solution to resolve several camera port damages which frequently happen using multi-camera set-ups.

Now, after a long year testing on several prototypes, the LockPort5 is for sale!

The full-size HDMI 90° output can be used in FRONT or REAR position (2 different adapters) to reach the best cable ergonomics solution on your rig set-up!

The LockPort5 adapters are available in FRONT and REAR editions, also available in kit or sold separately! Instant reverse output direction set-up.

Can be ordered now, estimated delivery for end of October/first week of November.

Price List USD 99.00

The LockPort5 Universal Edition is coming soon.

The Universal Edition can be used on every rig/fluid head with your 5D camera. Aerospace technology is used to make it incredibly lightweight and strong!

Fits directly with original head/support screws on every support out there.

The LockPort7 for 7D cameras is coming soon with the same innovative features.

  1. Any more information on the universal edition? It would be nice if someone designed one that mounted on the camera’s eyepiece (like the new loupe solutions that have come out) rather than the base of the camera.

  2. Great idea, I’ve already repaired one.
    RRM is only compatible with?
    I need to Genus.
