If I'm not mistaken, the R10 lacks a feature I consider important, In-Body-Image-Stabilization (IBIS).
Furthermore, for light weight you might consider the pocketable (if you have large pockets) ZS100 or ZS200. I got the ZS100 before the 200 came out and am very happy with it. Be advised that the flash on pocketables is weak and there is no hot-shoe.

First of all, phone cameras have gotten pretty good. While I love the 2 Panasonic pocketable models I own (Lumix DMC-ZS100, DCZS80), I wonder how much better they are than the best cell phone cameras. The 80 has a wider zoom range, the 100 has a better 1" sensor. Compare those 2 here:

Sony make a more expensive model with 1" sensor, the DSC-RX100 VII.
There are many other models and other brands, some with wider lenses with less zoom range. I wouldn't consider any model that doesn't have a viewfinder.

Bridge cameras offer a wide range of focal lengths in a medium size package, all in one lens. Technically, they have 1/2.3" sensors, but there are also models with better 1" sensors but with less zoom range. I love my old Canon SX50 HS, now a SX70 HS. There are many competing brands with varying differences. Nikon has the widest zoom range with the COOLPIX P1000 and P950, but I haven't heard much about them.
As far as those with 1" sensors, Panasonic makes 2, the Lumix DMC-FZ2500 and the Lumix DC-FZ1000 II. Sony makes the much more expensive Cyber-shot DSC-RX10 IV.
While the Sony models are considered a better camera, it has been said the menu system is difficult to follow and their prices are high.

The best cameras are the Interchangeable Lens Cameras (ILCs), the DSLR and mirrorless models. Note that once the first camera is chosen with flash and other accessories, one tends to be married to the brand, at least to keep using the flash, lenses, and so on. Mirrorless is the new standard while DSLRs can be had for less. Lenses made for DSLRs can later be used on mirrorless models with an adapter. One must also decide between full frame and APS-C (crop) models, but that is for a later discussion.

The FZ200 is an 11 year old model, now replaced by the FZ300. Both are 12 MP 1/2.3" sensor 24X lens models. 12MP is rather low by today's standards, but the f/2.8 lens is unusually wide open, a good thing.
I have both a ZS100 (1", 20 MP, 10X lens) and the ZS80 (1/2.3", 20MP, 30X). I like them both and use them almost interchangeably. The ZS80 has more "reach", the ZS100 is better in low light.

My R7 makes video in MP4 format. My Windows 11 computer can play them in Media Player, Real Player, or QuickTime. The problem may come from the settings of movie recording size.

My camera has C1, C2 and C3. I take many photos of live music performances and have set C1 for flash (1/320, f/8, 800 ISO) and C2 for ambient (1/60, f/8, Auto ISO). I haven't set C3. The f/8 is because the zoom lens wide open at its longest is f/6.3.

If you double click the filename of a jpg file in Windows directory, it opens it in the program (app) previously designated as the default program.

To open it with anything else: left click the filename once to highlight it->RIGHT click it->"open with"->then double left click the program you choose

To set a new default: left click->RIGHT click->"open with"->"choose another app"... then left click (once) the program you choose, then choose "always" to set a new default.

Small and lightweight is at odds with top quality images. The more of 1, the less of the other. The 1" pocketable or bridge cameras are in the middle with good quality and lightweight. I favor the Panasonic offerings because of the bang for buck. The ZS100 (aka TZ100) or ZS200D pocketable or the FZ1000 or FZ2500 bridge cameras in particular. The much more expensive Sony models competing are the RX100vii pocketable or the RX10iv bridge. I wonder if the pop-up EVF on the RX100 is too weak to stand up to rough handling. Also, some comment that the Sony menus are not very intuitive. However, they may have slightly better quality images.

The 1" sensor models are much better than the 1/2.3" alternatives (in similar packages) in having lower noise levels, especially important in low light situations.
The bridge models have more "reach" with zooms that go further into the tele range but are bigger.

I own the ZS100 and love it. The only drawbacks for me is that the built-in flashes on pocketables aren't very strong, and my subjects need long lenses, so I also have the ZS80, a 1/2.3" model which allows for longer "reach".

This would be my solution as well.

It is a true 18-55 and is a crop lens, meaning it will not fully cover a ff sensor. That is the meaning of the EF-S designation.

Ditto!

Thanks for the subject. It made me research how to set my camera for HSS!

He said he used the camera's meter for the exposure. Granted a slower speed and lower ISO might improve it, but that should wash as far as exposure is concerned.
I noticed the EC was at 0.

OK - Just to be accurate, that is comparing 2 different things. The 600 is a 35mm equivalent, or it magnifies as much as a 600mm lens on a 35mm (full frame) camera. The 140 is a true 140, but with the 1.5 crop factor camera, it has a 35mm equivalent of 140 X 1.5 or 210mm.

The FZ200 is an older camera. So is the FZ80. You might want to compare them. They are both 1/2.3" sensor types.
