Canon's ultra-slim 1-inch compact — 28-84mm equiv f/2-4.9 in a pocket the size of a credit card holder.
The Canon PowerShot G9 X was released in 2015 as a pocketable premium compact featuring a 1-inch 20.2MP CMOS sensor in a slim body at approximately 206g. The lens covers 28-84mm equivalent at f/2.0 maximum aperture wide. 1080/60fps video. NB-13L battery. The G9 X targets the pocketable premium compact segment where 1-inch sensor quality is required without the bulk of larger enthusiast compacts.
1-inch 20.2MP CMOS sensor. 28-84mm equivalent zoom (3x), f/2.0 (wide) to f/4.9 (tele). 1080/60fps video. NB-13L battery rated approximately 220 shots CIPA. Body weight approximately 206g with battery. WiFi and NFC. 3.0-inch touchscreen LCD. Fixed 28-84mm lens; no interchangeable mount.
The 1-inch sensor provides meaningful image quality improvement over smaller 1/2.3-inch compact sensors: larger photosites enable better low-light performance and more depth of field control at f/2.0 wide aperture. The 206g weight enables genuine jacket-pocket carry. The 28mm equivalent wide end provides environmental framing that 35mm-starting compacts cannot match.
On the used market the Canon G9 X is affordable as a pocketable 1-inch compact. Condition checks: NB-13L battery health (shared with G7 X, SX720 HS, G9 X Mark II), touchscreen for scratches, and lens element for marks. Fixed 28-84mm lens; no interchangeable mount.
