A great camera for little moneys
These cameras are dope!! Quality video quality. I'm really happy with the angle variety. I make you tube videos and they work great for what I do. The only gripe I would have is battery life....it's hit or miss. Sometimes they last a while and sometimes they don't. Other than that I could do with out the touchscreen. I will buy again though, I'm sure.

great value!
This is a great camera for the price. I've had action cameras that cost five times more but this camera does everything I need for a fraction of the price. The video quality is fine and it's easy to use, plus it comes with more adapters and fittings than i know what to do with.

3rd Time is the Charm - Love the Insta360
I got this camera as a replacement for an Akaso Brave 4 who did not perform the way as advertised.The Insta360 ONE RS performs very well even on lower light settings when compared to other cameras I tried. It is easy to handle, the menu and touchscreen are intuitive and easy to navigate.Charging the camera (battery) as straight forward and can be archived with either a regular USB charger (as long as it has an USB-C to connect to the camera) or it can be charged via the USB port on a computer as well.The image quality is overall very good, and the camera provides plenty of options to customize the experience.My only complaint is that the built-in microphones seem to have a tendency to create some kind of electronic and buzzing noise in the recordings. It could be that this is a problem with the audio settings and the way I tried and tested them. But, I found this issue can also be overcome with a fairly cheap external microphone.

ottimo anello per macro
Eccellente anello ottico che permette di riflettere il flash tramite uno specchio attorno all'obiettivo annullando qualunque effetto ombra. peccato solo per il prezzo

Q
Can the adapter be adjusted if the focus point of the lens is not at the top or if focusing at infinity is not possible? Thanks
A
no. 
Q
Does this stop at infinity or does it focus past infinity? I need a simple infinity only adapter.
A
This has no focusing capability. That said it will allow your lens to infinity focus the same way as it did on its original mount. It won’t change that. The only issue I can imagine is the quality control issue if any from adapter to adapter, manufacturer to manufacturer. Basically if your lens goes past infinity then it won’t change anything with it mounted on this adapter or any other 
Q
Which M42 adapter should be used on your lens?
A

Please note: our M42 adapter ring could not be suitable for Pentax Takumar Super Takumar Carl Zeiss M42 series（aperture pin does not fully depress, small tabs sticking out), as ours depresses the aperture pin all the way down

 
Q
Infinity focus place
A
The longer Flange distance lens to the shorter Flange distance camera, then could use the infinity focus.
but if the shorter Flange distance lens to longer Flange distance camera, then could not use the infinity focus, you can focus on a limited distance.
the position of the infinity mark 【∞】of the telephoto lens or super telephoto lens is shifted slightly to the positive side to enable focus adjustment even when focus shift is caused due to temperature changes.The shift range is denoted by an L-shaped line, Be sure to check the focus through the viewfinder even when you shoot at infinity. 
Q
Does this adapter allow for canon fd lenses to focus to infinity on sony e-mount mirrorless cameras?
A
yes, i had no problems with infinity focus with this adapter. the only FD mount lens i use anymore with my sony is a vivitar 20mm, and i pretty much only shoot infinity focus with it.
