This HDMI to mini HDMI adapter is used by me at my Sony camcorder to be connected to an Onkyo TX-NR515 AV Receiver. For that I have just a normal HDMI cable connected to the HDMI input 5 of Onkyo and insert the adapter as needed simply to. The gold-plated plugs optimal signal path is ensured. The connection is very stable on both sides, because nothing wobbles. Nevertheless, you should just the camcorder take care not to bring too much train on the cable so as not to damage the port. (This applies, of course, but not only when using this adapter but all mini-HDMI cable).
Fortunately, also works the CEC control the camcorder from the Onkyo remote control with this adapter. The adapter supports the HDMI 1.4 standard and therefore also 3D, 4K2K, ARC and Ethernet.
In the overall assessment, I can therefore recommend the adapter. A practical solution if you want to buy a separate mini-HDMI cable. The adapter can also be transported easily with the camera bag due to its small size and has him so at your fingertips.
I hope this review could assist you in your buying decision ...
