Canon G1 X Mark II Performance


Timing and Performance

Generally faster performance than the G1 X, but slow RAW mode burst speeds.

Startup/Play to Record

Power on
to first shot

~2.0 seconds

Time it takes for LCD to turn on and lens to deploy and capture a picture.

Play to Record,
first shot

~1.5 seconds

Time until first shot is captured.

About the same startup time as the G1 X (which took ~1.9s), but slower than most Compact System Cameras (though most CSCs don't have a zoom lens to deploy). Improved Play to Record speed (G1 X took ~2.2 seconds).

 

Shutter Response (Lag Time)

Full Autofocus Wide

0.213 second

Time from fully pressing shutter button to image capture, zoom lens at wide angle position.

Full Autofocus Tele

0.365 second

Time from fully pressing shutter button to image capture, zoom lens at telephoto position.

Full Autofocus
Center-area AF
Flash enabled

1.027 seconds

Time to capture while forcing flash to fire, zoom lens at medium focal length.

Manual Focus

0.238 second

For most cameras, shutter lag is less in manual focus than autofocus, but usually not as fast as when the camera is "prefocused".

Prefocused

0.091 second

Time to capture, after half-pressing and holding shutter button.

The Canon G1 X II's full autofocus shutter lag when shooting the same target multiple times was faster than average for a fixed-lens enthusiast camera (especially at wide angle), and much improved over the G1 X. The G1 X II's full AF shutter lag clocked in at about 0.21 second at wide angle using center (1-point) AF, which is quite fast. Full AF shutter lag was slower at full telephoto, measured at 0.37 second, though that's still not bad. In comparison, the G1 X required about 0.7 second at both ends of the zoom, so that's quite an improvement. Enabling the flash raised shutter lag to a rather lengthy 1.03 seconds to account for the metering preflash (still faster than ~1.2 seconds for the G1 X). Manual focus shutter lag was 0.238 second (versus 0.412s). When prefocused, shutter lag dropped to 0.091 second (vs 0.094s), which is a little slower than average these days, but still pretty quick.

 

Cycle Time (shot to shot)

Single Shot mode
Large Super Fine JPEG

1.01 seconds

Time per shot, averaged over 20 shots.

Single Shot mode
RAW

1.14 seconds

Time per shot, averaged over 20 shots.

Single Shot mode
RAW + LSF JPEG

1.24 seconds

Time per shot, averaged over 20 shots.

Early shutter
penalty?

No

Some cameras don't snap another shot if you release and press the shutter too quickly in Single Shot mode, making "No" the preferred answer.

Continuous mode

Large Super Fine JPEG

0.19 second (5.26 frames per second);

Flash recycling

3.2 seconds

Flash at maximum output.

*Note: Buffer clearing times measured with a SanDisk Extreme Pro 95MB/sec UHS-I SDHC memory card. Slower cards will produce correspondingly slower clearing times. Slow cards may also limit length of bursts in continuous mode. ISO sensitivity also affects cycle times and burst mode performance, with higher ISOs generally increasing cycle times and reducing burst performance.

Shot-to-shot cycle times were fair in single shot mode, ranging from about 1 second for Large/Super Fine JPEGs to about 1.2s for RAW+LSF JPEG files. These results are noticeably faster than the G1 X's 2.7 to 3.6s range, but are still slower than most CSCs which average well under 1 second.

The PowerShot G1 X Mark II's fastest continuous shooting mode rate was decent at almost 5.3 Large/Super Fine JPEG frames per second, however focus and exposure are locked at the first frame of a burst in this mode. When shooting RAW files, though, burst speed fell dramatically to 1.45 fps for RAW-only, and 1.27 fps with RAW+JPEG frames.

With autofocus enabled, the frame rate dropped to about 3 fps for Large/Super Fine JPEGs. Burst rate fell further in RAW mode to only 0.81 fps and only 0.75 fps for RAW+JPEG pairs, which is quite slow. These results are however improved over the G1 X, which could only manage 0.7 fps with AF according to Canon even with just JPEGs, and 4.5 fps in a special High-speed Burst HQ JPEG mode with AF locked.

Buffer depths were excellent in all continuous modes, probably just limited by card space, and clearing was quite swift, never requiring more than 4 seconds after a 20-shot burst with a fast 95MB/s UHS-I card.

The built-in flash took an average of 3.2 seconds to recharge after a full-power discharge, which is not bad, and much faster than the G1 X's 5.9 seconds.

 

Bottom line, the Canon PowerShot G1 X Mark II's overall timing performance is generally improved over the G1 X's, particularly autofocus speeds, but still somewhat disappointing with sluggish power-on and poky burst performance particularly with RAW files. While the improvements over its predecessor are most welcome, it still can't really compete with most Compact System Cameras when it comes to burst speed, and is slower than many digicams these days as well.

The Canon PowerShot G1 X Mark II uses a custom NB-12L rechargeable lithium-ion battery for power, and ships with a dedicated charger. CIPA battery life is well below average for a mid-sized camera at only 240 shots per charge when using the LCD (and even lower with the optional EVF), though there is an Eco mode which improves battery life to 300 shots by dimming and then shutting off the LCD more quickly than normal in shooting mode. Still, we strongly recommend you pick up a spare battery for extended outings.

The table above shows the number of shots the camera is capable of (on a fully-charged rechargeable battery as appropriate), based on CIPA battery-life and/or manufacturer standard test conditions.
