Autofocus, exposure and image quality

For automatic focusing, both Powershots use a contrast AF with 31 fields, configurable as a single-frame AF or as a continuous autofocus. Also possible are single-field AF (variable measuring field size) or spot AF, and – thanks to the touch-sensitive monitor – touch autofocus / trigger. The MF Peaking feature supports manual focus. A “five-axis image stabilizer” keeps the image pleasantly quiet.


Autofocus and exposure


The autofocus operates reliably and at the G5 X very fast: 0.20 s at 300 lux and 0.27 s at 30 lux are top values. The G9 X can only keep up with good light (0.24 s), while the 309 lux is up to 0.43 s.

The two 3-inch touch displays have 346 667 RGB pixels, are crisp sharp and convincing with very good color reproduction. Fonts and symbols are well represented, but are somewhat small and sometimes difficult to recognize. The display brightness is adjustable in five steps. The graduation is clear and consequently also practical in practice. The display of the G5 X can also be swiveled and swiveled, thus allowing unusual shooting positions. Also Selfies are better to control - the G9 X, on the other hand, you have to estimate the image cut when you look at the camera from the front.

The G5 X has an OLED viewfinder with 786 887 RGB pixels and a 100% effective image size. It is 0.39 inches in size, not very generously dimensioned, but the good quality of the picture should even reconcile spectacle wearers. On the left side of the viewfinder, the dial for diopter adjustment is well positioned and poorly adjustable. But in this case, this is even useful, so it can not be unintentionally twisted.


Image quality


The viewfinder is turned on and off by an approximation sensor. As soon as the eye approaches the viewfinder, the sensor turns off the display and the viewfinder. If the eye removes itself from the viewfinder, the other person passes by. Like the brightness of the display, the brightness can also be adjusted in five steps. However, the brightness levels are not very different.


The ISO range is from 125 to 12 800 with manual adjustment and from 125 to 3200 with Auto ISO, the shutter speeds range from 30 s (long-term exposure) to a short 1/2000 s. An ND filter that reduces the incident light quantity by 3 The G5 X: this camera can be played with the aperture even in daylight thanks to the high aperture aperture. (G9 X: 7.0 B / s) in JPEG format, and RAWs with 0.8 B / s (G9 X: 0.7 B / s), the G5 X makes the G5 X at 6.9 B / s. The software Digital Photo Professional for developing the RAW images is included in both models.


The 1-inch sensor is a back-lit CMOS with an effective 20.2 megapixel resolution (5472 x 3648 pixels), a current Digic-6 processor processes the images fast. Using WLAN and NFC, both cameras can be controlled or transferred to a mobile device. You can find suitable apps in the app stores of Apple and Google.


Basically, both cameras provide very similar images with comparable resolution and coordination. The G5 X's more powerful lens gives this model a slight lead. Compared to other cameras with a 1-inch sensor, the resolution is absolutely competitive in both test devices and the ISO-100 image is convincing. Only the edge sharpening could be somewhat more reserved. It can provide double contours for unfavorable subjects. If you do not like this, you can shoot with both cameras in RAW mode as well.


The noise characteristics largely independent of the optical equipment are almost identical for both models and increase linearly from ISO level to ISO level. In the case of ISO 400, the noise is already clearly visible in monochrome surfaces. In addition, ISO 400's fine-tuning is a bit too strong for a camera with a 1-inch sensor - some competitors are getting better. From ISO 800, artifacts are also visible in pictorial structures. In this case, the sensor size reaches its limit - larger sensors are also necessary for better image quality. The dynamic range is good for both cameras with 11 f-stops at ISO 100 and more than 9 f-stops up to ISO 1600.


If you like a compact camera forever, you should take a look at the two new Powershots. While the G9 X looks and looks very similar to the RX100 models from Sony, Canon's G5 X has its own unique way of design and operation. Thanks to many operating elements and a well-thought-out function concept, it can be perfectly adapted to your own needs. This makes them a tip for photo-individualists. The processing is high-quality, and the equipment with WiFi, NFC, light-heavy 4x zoom and a high-quality electronic viewfinder up to date - that should be at the price of almost 800 euros but also self-evident. The image quality is in the range of the 1-inch standard: good at ISO 100 and fast-decreasing. Above all, air is still at the top of ISO 400.
