Autofocusing was noticeably better than in the previous model. Locking-on was fast và accurate in most types of lighting, including on a very rainy day where contrast was particularly low. Hunting was seldom encountered, even in low light levels.

Consequently, we’ve nominated it as an Editor’s Choice ““ specifically for buyers who can tolerate the lack of a viewfinder.

 

Full review

Canon’s new PowerShot G7X Mark II addresses some of the criticisms levied at the G7X and adds some worthwhile improvements without increasing its price. Physically similar to lớn its predecessor, the Mark II has the same 20.1-megapixel CMOS sensor và 4.2x optical zoom lens & remains limited khổng lồ 1080/50p đoạn phim recording for PAL format. A new DIGIC 7 image processor boosts continuous shooting performance to eight frames/second for both JPEG và CR2.RAW files. Autofocusing và noise performance have also been improved.

Check out our đánh giá of the original G7X for details on image and đoạn clip recording sizes và capabilities, in-camera adjustments that carry over into the new camera, the Wi-Fi và NFC options & the playback and software. Unlike the G7X, the new camera giaithuongtinhnguyen.vnes without a software CD but all necessary software ““ and copy of the full user manual in PDF format ““ is available for downloading from Canon’s website.

Who’s it for? The Mark II suffers from the same deficiency as plagued its predecessor: the lack of a viewfinder (or any way khổng lồ attach one). This is likely to deter many potential purchasers. No matter how good LCD (and OLED) screens are, in bright sunlight, they force users into point-and-guess framing most of the time.

Some of the adjustments to lớn the toàn thân design and the updated DIGIC 7 processor will make it more giaithuongtinhnguyen.vnpetitive with equivalent models in Canon’s digicam stable và similar cameras from giaithuongtinhnguyen.vnpeting manufacturers. However, unlike some giaithuongtinhnguyen.vnpeting cameras, the G7X Mark II lacks support for 4K đoạn phim and really needs a built-in EVF.

What’s New? The changes lớn the toàn thân design have made small but significant improvements to its operability. The first addition is a small front grip moulding, which is covered with the same rubber-like material as is used for the rest of the front panel. This improves grip security significantly and is welgiaithuongtinhnguyen.vned.

The redesigned front control ring includes a new switch, located on the lower left hand side, which makes it easy to swap between smooth turning và stepped rotation with click stops. The monitor screen can now be tilted down through 45 degrees in addition to the 180-degree flip-up offered on the G7X.

A new Wi-Fi button has been added lớn the right hand side panel of the camera, just below the USB/HDMI terminal giaithuongtinhnguyen.vnpartment. This button is very small & lies flush with the camera body toàn thân but it’s better than having the Wi-Fi giaithuongtinhnguyen.vnbined with the drive settings as it was on the G7X. Wi-Fi functionality is the same as in other Canon cameras. Otherwise, the external design of the Mark II is identical lớn the original G7X.

Internally, many more changes have taken place, most of them associated with the new DIGIC 7 processor chip. The most significant is likely lớn be the improvements khổng lồ continuous shooting, where the vị trí cao nhất speed has been boosted from 6.5 fps lớn 8 fps. Even more significantly, the burst rate of 8fps is available for CR2.RAW files, whereas in the Mark I the continuous shooting tốc độ for raw files was only 1.2 fps.

Also for raw files, the images are now 14-bit, a step up from the 12-bit RAW files captured by the G7X. This brings the G7X II into line with the PowerShot G3X, G5X, và G9X cameras. In-camera RAW conversion enables users to adjust brightness, white balance and Picture Style và configure the tự động hóa Lighting Optimiser and noise reduction settings before saving the adjusted images as JPEG files. You can also save the adjustments for future use on other raw images.

Another DIGIC 7-related improvement is in noise handling across the camera’s ISO range, which is now expandable to lớn ISO 25600. The new processor also improves face registration & speeds up subject detection in difficult lighting, particularly with low-contrast subjects that have subdued saturation. Battery life has also been increased by just over 25%.

Autofocusing improvements include a new panning feature that enables users to record moving subjects with a blurred background that conveys a sense of speed. The camera will detect and lock focus on the subject as the camera is panned khổng lồ track it and users can adjust the degree of blurring with the lens control ring. Image stabilisation is controlled automatically, depending on the direction of the pan.

A new time-lapse movie feature has been added to the G7X II’s clip capabilities. Users can phối the intervals between frames between one and four seconds và record between 30 and 900 shots per sequence. The camera’s thực đơn displays the time required to record the sequence và the playback time for the resulting movie clip.

Picture Styles, a suite of adjustment pre-sets familiar lớn users of Canon’s EOS DSLR cameras, makes its first appearance in a PowerShot camera. A new Fine Detail option has been added to lớn the regular Auto, Standard, Portrait, Landscape, Neutral, Faithful, Monochrome và three User Defined settings.

Users gain the ability to adjust contrast, sharpness and colour in-camera to match settings in their EOS DSLRs. Adjusted settings can also be tweaked with Canon’s Picture Style Editor & saved as new Picture Styles. Note: Picture Style adjustments are ONLY applied to JPEG files.

Finally, the PowerShot G7X Mark II supports USB charging, although a USB cable is not provided with the camera. It ships with a dedicated charger, battery and wrist strap and, although one was supplied for our review, no mains cable is listed in the box contents.

Performance Still images from the camera were a bit more ‘punchy’ than those from its predecessor, although they also required a little unsharp masking in Photoshop to lớn bring out their details. Colours recorded showed the usual slight increase in saturation we’ve giaithuongtinhnguyen.vne to lớn expect from giaithuongtinhnguyen.vnpact digicams và this proved an advantage in test shots taken under wintry skies & after dark.

Colour accuracy was generally very good, particularly for greens & blues. Imatest showed a tendency khổng lồ boost warm hues, which would result in ‘healthier-looking’ skin tones.

Autofocusing was noticeably better than in the previous model. Locking-on was fast and accurate in most types of lighting, including on a very rainy day where contrast was particularly low. Hunting was seldom encountered, even in low light levels.

Imatest showed JPEG files from the nhận xét camera were able to meet expectations for the sensor’s resolution at a focal length of 22.3mm in the middle of the aperture range. CR2.RAW files converted into 16-bit TIFFs with Adobe Camera Raw, shot at the same time had slightly higher resolution. Edge resolution in each case fell slightly short of expectations.

Resolution held up well across the đánh giá camera’s sensitivity range with a slow decline in sharpness as ISO settings were increased. Noise was visible in JPEGs taken with the two highest ISO settings but at sensitivities of ISO 3200 và below, files were effectively noise-free và very clean. As usual, raw files had a clear-cut advantage over JPEGs. The graph below plots the results of our tests.

Diffraction took effect from about f/5.6 on, with the decline increasing between f/5.6 and the minimum aperture of f/11. The graph below plots the results of our tests across the aperture ranges for four focal length settings.

Lateral chromatic aberration was negligible at all lens apertures và focal length settings. The graph below shows the results of our tests, with the red line indicating the boundary between negligible và low CA.


Auto trắng balance performance was typical of many digicams, with close-to-neutral colours under fluorescent lighting and with the camera’s built-in flash but insufficient correction of incandescent lighting. The tungsten và fluorescent pre-sets tended towards slight over-correction with the former introducing a blue cast và the latter a purple one. No adjustments appeared to lớn have been made with the flash pre-set và manual measurement produced neutral colours under all three types of lighting.

Flash performance was as consistent as we found with the original G7X and image quality varied from very good to acceptable across the sensitivity range from ISO 125 lớn ISO 12800. Shots taken with the highest ISO setting showed slight softening & marginally lower contrast & colour saturation than shots taken with lower ISO settings. But they would be usable for small prints & provided some scope for improvements with effective editing software.

Video performance was similar to the original G7X and rates as satisfactory, rather than outstanding. Even the fastest frame rate was unable khổng lồ lock onto vehicles travelling along a main urban road but the AF system had few problems locking onto moving subjects and tracking them throughout a clip. Soundtracks were of average unique without much stereo presence.

Our timing tests were carried out with a 16GB Panasonic SDHC UHS-1 U3 memory card, which claims write transfer speeds of 45MB/second. The nhận xét camera took just over two seconds lớn power up ready for shooting, which is relatively slow. With the lens at medium zoom we measured an average capture lag of less than 0.1 second, which was eliminated with pre-focusing. On average, it took 0.55 seconds to process each high-resolution JPEG image, 0.6 seconds for a raw file and 0.62 seconds for each RAW+JPEG pair. Shot-to-shot times averaged 0.6 seconds without flash và 5.2 seconds with.

In the high-speed continuous shooting mode, the camera recorded 33 Large/fine JPEG frames in 3.7 seconds before beginning khổng lồ slow down, which is somewhat faster than specified và could be due lớn using a fast memory card. It took 8.2 seconds to process this burst. In the continuous mode with autofocusing, we were able lớn record 48 frames in 8.0 seconds before the first sign of hesitation. Processing took a further 8.6 seconds.

With raw files, we were able to lớn record 41 frames in 2.2 seconds before capture rates slowed. Processing was giaithuongtinhnguyen.vnpleted after a further 7.6 seconds. With RAW+JPEG pairs the buffer filled at 39 shots, which were captured in 2.0 seconds. Processing this burst was giaithuongtinhnguyen.vnpleted within 17.2 seconds.

Conclusion The absence of a built-in viewfinder will always be a deal-breaker for us so we’re inclined lớn regiaithuongtinhnguyen.vnmend the PowerShot G5X, which has a high-resolution EVF built-in, over the PowerShot G7X Mark II. Particularly in the Southern Hemisphere, where skies are often clear, any kind of viewfinder, no matter how basic, is better than none at all.

However, aside from that, the new camera provides some worthwhile improvements on its predecessor and is a better all-round performer. Consequently, we’ve nominated it as an Editor’s Choice ““ specifically for buyers who can tolerate the lack of a viewfinder.

Local shoppers will find discounting has already started for the G7X Mark II & is well established for the G5X. It’s not worth shopping off-shore as the even the discounted prices listed on the major US re-sellers’ websites are within a whisker of (or slightly above) the prices listed in Canon Australia’s online shop. When you địa chỉ the cost of shipping you would pay more than AU$900.

But it will pay to kiểm tra out a number of local re-sellers. The cheapest price we’ve found for the PowerShot G7X Mark II is AU$759 for a ‘special’ offer, which may be a one-off end-of-financial-year price. Otherwise, going on listed prices when this reviews was posted you can expect to lớn pay between AU$820 & $850 for the new G7X Mark II or around $900 for the G5X.
