Canon powershot g7 x vs canon powershot g9 x?
Both are fixed-lens compacts with the same 1-inch, 20.2-megapixel sensor, so the choice really comes down to the lens.
I'd pick the Canon PowerShot G7 X for most people. Its 8.8-37mm lens frames like 24-99mm on full frame, and at f/1.8 to f/2.8 it gives about the depth of field of f/4.9 to f/7.6 there, which helps in dim rooms and with background blur.
The Canon PowerShot G9 X reaches less far. Its 10-31mm lens frames like 28-83mm and runs f/2 to f/4.9. It only makes sense if you mostly shoot wider framings.
If you want something newer, the Canon PowerShot G7 X Mark III is a vlogging favourite with a flip-up screen.
