I decided for this one after comparing it to Sony and a Lumix. by searching the Internet, I found the drawbacks to the other 2 (pb goal sealing for sony, zoom on the Lumix less). Anyway, at some point, we must make a choice and so this is the gun that was selected.
Get used to 30x zoom including aiming. A support may be required.
Until now (2 weeks of use) this device suits me well.
The contents of the gun cabinet could include the HDMI cable and USB connection cable for transferring images to the computer.
Also note that on my previous canon, the strap was equipped with a small ring that allows to tighten the strap on the wrist, this is not the case with this one .. but that's a detail.
