Not really.. -Wait and see. I've already tried my luck with Panasonic directly.

Memory cards are never included with cameras. Except for special kits where it is explicitly mentioned.

No

I would recommend a good brand SDXC card such as Sandisk Extreme Pro in the UHS-I version. They have become quite cheap in the meantime. It is said here that UHS-II cards have an advantage: https://www.speicherkarten.guru/-Kameras/Panasonic-Lumix-GH5 However, one may ask whether the massive additional price is worth it. The memory speeds are not nearly exhausted.

The HDMI connection is type A

I recently purchased this camera here, the latest firmware update 2.6 was already installed, lens firmware 1.1. V Log must be purchased and installed separately. The lens hood was missing from my camera. Despite writing to Galaxus several times, I have not even received a reply, let alone the missing lens hood. Panasonic immediately responded to my letter but referred me to the dealer/Galaxus. The camera is top, I am very satisfied with it. Greetings, Rainer

The lens makes the difference. The Leica 12-60 is an excellent lens and worth every penny. That's Leica for you. The aperture value of the Leica lens is f2.8 - f4.0. With the Panasonic lens it starts at f3.8 and goes up to f5.6 in the zoom range. This means that at a focal length of 60mm, the smallest aperture for the Leica is f4.0 and for the Panasonic 5.6. The Leica alone costs CHF 799. Panasonic 12-60mm f/2.8-4.0 ASPH. Power O.I.S. The Panasonic only CHF 372.-, that is over 400 roubles less. Panasonic 12-60mm f/3.5-5.6 ASPH. Power O.I.S. The premium on the Leica lens is more than justified. I've shot some professional films with the GH5/Leica kit and was always very satisfied.

Well, the 12-60 mm Obi. is an ideal zoom. But if you need more telephoto, then I recommend a zoom 12-120 mm. But that is already heavier! An additional alternative would be 30-100 mm. Panasonic has several suitable Obi in stock. As a directional mic I would take a Sennheiser mic. Sennheiser has been a leading manufacturer of microphones for over 50 years.

Unfortunately, we do not have this information yet.

Well, I've probably been able to find out the difference between the two versions: there doesn't seem to be one. Apparently, rumours about the "E version" are circulating on the internet. A specialist explained to me that the "E" probably stands for Europe.

Pretty sure. Sigma 12-35mm was made for APS-C and the GH5 has MFT... so smaller sensor. That's why it's not a problem. The Metabones allow you to focus.... not as fast but it's enough for most things.
