Canon PowerShot G7 X Mark III

The PowerShot G7 X Mark III is a compact camera from 2019 built around a one-inch sensor and a lens fixed into the body.

That mix suits travellers and everyday photographers wanting a camera that fits a jacket pocket, along with creators drawn to the adjustable screen and wireless connectivity.

It measures 105 x 61 x 41 mm and weighs 304 g, so it carries almost unnoticed. The 235-shot battery rating and single card slot mean a spare of each is worth packing on longer days.

Stills start with a 20-megapixel CMOS sensor in the one-inch format. That resolution leaves some room to crop, while the fixed-lens compact design keeps the camera ready as one unit.

The lens is fixed to the body, so the camera travels and readies as a single unit. You gain simplicity, at the cost of never swapping glass for a different focal range.

Autofocus uses 31 points, and sensitivity runs from ISO 125 to 12800, leaving room to keep shutter speeds workable as light falls. The 1/2000s maximum shutter can limit wide-aperture shooting in bright light, where a neutral-density filter may help.

The top shooting speed of 30fps is a maximum rather than a sustained rate, so time the decisive moment instead of holding the button down. Stabilisation in the body reduces camera shake for handheld work at slower speeds, though it will not stop a moving subject. Framing is screen-only, since no viewfinder is fitted.

Video records at up to 4K, its maximum resolution. Those pixels leave room to crop or reframe footage when you edit.

Frame rates reach 120fps, which brings slow-motion work within reach, suiting sport, water and everyday motion that looks ordinary at normal speed. The peak resolution and the peak frame rate are separate maximums, so confirm which modes pair together before planning a slow-motion shoot.

The screen flips and responds to touch, supporting composition from different angles. Touch input is available for on-screen interaction. With no viewfinder fitted, the screen is the only built-in framing aid.

A timelapse mode is built in, covering interval projects without an external controller. Files record in MPEG-4.

The 3-inch TFT screen carries 1,040,000 dots for reviewing images. It flips to support angled framing and responds to touch, giving the compact camera an adjustable rear display.

Wi-Fi and Bluetooth are both built in, giving the camera two ways to connect wirelessly to other devices.

A flash is built into the body for extra light in dim rooms. There is no support for an external flash, so larger lighting setups are not an option here.

Neither built-in GPS nor weather sealing is fitted. The camera does not record location data by itself, and it should be kept sheltered when conditions turn wet or dusty.

The single slot accepts SD, SDHC and SDXC cards with UHS-I compatibility, so UHS-I cards can be used. With only one slot there is no second copy of a shoot, so packing a spare card is a sensible precaution.

Power comes from a Canon NB-13L battery rated at 235 shots per charge. Treat that as a rated figure rather than a promise, since the screen, video and wireless connections all draw power, and a second battery earns its place on longer outings.

Charging over USB is supported, so the battery can be topped up through the camera's USB connection between shoots or during a travel day.
