Canon powershot g7 x vs sony rx100 iii?

Both cameras use the same 20-megapixel 1-inch sensor, announced in 2014, so image quality should be close. The difference is the lens. The Canon PowerShot G7 X's 8.8-37mm zoom frames like 24-99mm on full frame, while the Sony RX100 III reaches 24-69mm, so the Canon gives you more reach. Its f/1.8-2.8 aperture is the same on both.

Pick the Canon PowerShot G7 X if you want the longer zoom. Pick the Sony if you want its pop-up viewfinder. My own preference is the Canon for general use, since reach matters more to me than the viewfinder.

If you're comparing newer models, the Canon PowerShot G7 X Mark III has a flip-up screen and suits vlogging, and the Mark II keeps the same bright zoom. For why a 1-inch sensor matters, see sensor sizes.
