Canon G7X II Image Quality Comparison

Below are crops from our laboratory Still Life target comparing the Canon G7X Mark II's image quality to its predecessor's, the G7X, as well as to a range of compact enthusiast cameras: the Canon G5X, Panasonic LX100, Panasonic ZS100 and Sony RX100 IV. All cameras in this comparison use 1"-type sensors except for the Panasonic LX100, which uses most of a Four Thirds sensor.

NOTE: These images are from best quality JPEGs straight out of the camera, at default settings including noise reduction and using the camera's actual base ISO (not extended ISO settings). Clicking any crop will take you to a carrier page where you can click once again to access the full resolution image as delivered straight from the camera. For those interested in working with the RAW files involved, click these links to visit each camera's respective sample image thumbnail page: Canon G7X II, Canon G7X , Canon G5X, Panasonic LX100, Panasonic ZS100, and Sony RX100 IV -- links to the RAW files appear beneath those for the JPEG images, wherever we have them. And remember, you can always go to our world-renowned Comparometer to compare the Canon G7X II to any camera we've ever tested!

Right off the bat, we see better color from the G7X Mark II than from its predecessor at base ISO, with much less of a green shift in yellows and beiges, and more accurate pinks. The G7X II image looks a bit punchier with slightly lower noise as well, though the G7X retains a bit more detail.

Unsurprisingly, image quality from the GX5 is nearly identical to the G7X as they use the same generation sensor and processor. Thus, again, the G7X Mark II shows better color, slightly higher contrast, slightly less noise, but not quite as much fine detail.

Here we compare the 20-megapixel 1"-sensored Canon G7X II to the 12.7-megapixel 4/3"-sensored Panasonic LX100. The resolution difference is very apparent here in both the relative element sizes and the higher detail from the G7X II at base ISO. But while the Canon's resolution is higher, noise is also a little higher, as you can see in the background of the bottle shoulder crop. The G7X II applies slighter stronger non-area-specific sharpening, though, which tends to exacerbate noise. Still, the Panasonic's larger pixels pay off in terms of slightly lower noise already at base ISO when comparing at 100% like this, but the G7X II still wins overall with a more vibrant, punchy image with better color.

The Canon G7X II "only" offers a 4.2x zoom lens compared to the 10x optical zoom of the ZS100, but it's a much brighter f/1.8-2.8 vs f/2.8-5.9 optic. However, both cameras use similar 1"-type 20-megapixel sensors, and are currently priced the same as well. Image quality here at base ISO is fairly similar, with about the same amount of detail captured along with comparable noise levels, however there are some notable differences. First, the Panasonic's tone curve is such that its image looks a bit darker than the Canon when middle gray is the same brightness, giving the G7X II's image a brighter look overall. Colors from the Canon are generally also more neutral and pleasing. The ZS100 does however hold onto more of the fine thread pattern our tricky red-leaf swatch, which the G7X II's default processing smooths over. Sharpening halos are also a little less noticeable from the Panasonic, though both produce visible haloing along high-contrast edges.

Sony RX100 IV at ISO 125

The Sony RX100 IV's image looks a little crisper and cleaner than the G7X II's at base ISO, and it retains better detail and contrast in the red-leaf and pink fabrics. However the Canon produces better color, a more natural noise pattern, and similar detail elsewhere. Both obviously do very well here at ISO 125, but keep in mind that unlike the Canon, the Sony can extend its sensitivity down to ISO 80.

Similar to the differences we saw at base ISO, the Canon G7X Mark II offers brighter, more accurate colors than its predecessor at ISO 1600. Noise levels are quite similar, but the G7X II does a bit better at retaining detail in our mosaic crop, while the G7X does a touch better with our tricky red-leaf swatch although both smudge most of the fine detail away. Overall, though, the G7X Mark II produces a more pleasing image.

At ISO 1600, we see the LX100 start to pull ahead of the G7X with better detail despite the lower resolution, as well as lower luma noise. The Canon does a little better with controlling chroma noise, though, with much brighter and more accurate colors. Both struggle with the red-leaf fabric with the Canon displaying more noise.

The ZS100 produces a cleaner looking image here at ISO 1600, however the G7X Mark II is sharper, holds on to more detail, and generates fewer noise reduction artifacts. Contrast and colors are still more pleasing from the Canon as well.

Both cameras work hard to keep noise at bay which causes a loss of fine detail as well as some unwanted noise reduction artifacts, especially from the Sony. Overall, the Sony still produces an image with more pop, but it also looks more processed, with less accurate color. The Sony produces higher contrast, lower noise and a bit better detail in our tricky red-leaf fabric, however much of the fine detail is heavily distorted.

Once again, although both siblings struggle with reproducing fine detail at ISO 3200, the G7X Mark II comes out on top with a brighter, higher-contrast image with better color. The G7X is noisier in our mosaic crop, however more noise reduction artifacts are seen from the Mark II. The G7X continues to do a bit better in the red-leaf swatch, however there's very little detail left.

Here at ISO 3200, the Canon G7X II shows much higher luminance noise, but it arguably manages to reproduce fine detail in our mosaic crop a little better than the ZS100, however both show strong noise reduction artifacts and mottling. Both cameras really struggle to reproduce any detail in our red-leaf swatch, but the ZS100 does show a touch more. Once again, color and contrast are better from the Canon.

Here at ISO 3200, noise appears a little higher from the Sony except in the red channel, and the Sony produces more noise reduction artifacts while smudging fine detail more in the mosaic crop. Again, color is generally better from the G7X Mark II, but the RX100 IV provides slightly higher contrast and does a bit better in the fabrics. Overall, though, we give the Canon the edge here.

Detail comparison. High-contrast detail is also important, pushing the camera in different ways, so we like to look at it, too. Here, we can see the G7X Mark II does a bit better than the G7X in terms of contrast, however the G7X does a bit better with fine detail at higher ISOs. Interestingly, both G7X models do a bit better than the G5X, particularly at ISO 6400. While the Panasonic LX100 produces lower contrast, it actually holds it own in terms of detail despite being lower resolution, besting the 1"-type models at ISO 6400, no doubt thanks to its bigger pixels. Compared to the Panasonic ZS100, the G7X II does a bit better in both contrast and detail across the range of ISOs shown here. The Sony RX100 IV did well at base ISO though with slightly lower contrast, however it couldn't retain as much fine detail as the G7X II managed at the higher ISOs.

 

Canon G7X II Print Quality Analysis

Excellent, high-resolution prints up to 24 x 36 inches at ISO 125-200; Nice 8 x 10 inch prints at ISO 3200; and usable 5 x 7 inch prints at ISO 6400.

Canon PRO-1000 Printer ImageISO 125/200 images look great all the way up to 24 x 36 inches. At this print size, you're pushing the limits of the 20MP sensor, but from a typical viewing distance for a print this large, image quality is impressive. There's a lot of crisp fine detail and pleasing, vibrant colors. ISO 200 images look practically identical to base ISO ones, especially in prints, with no visible increase in noise or decrease in detail that would impact print sizes.

ISO 400 prints start to display a slight drop in fine detail and a bit of visible noise back in the shadow areas. Therefore, we're putting the print size limit at a still-healthy 20 x 30 inches.

ISO 800 images show stronger noise, which subsequently reduces fine detail further and softens things up a bit more. At prints sizes up to 13 x 19 inches, quality is very good; there's still a lot of detail at this size, and noise remains limited to the shadows and has a rather fine-grained appearance. However, we'd be okay with a 16 x 20 inch print for less critical applications at this sensitivity.

ISO 1600 prints top-out at a respectable 11 x 14 inches. Noise is quite visible now at higher print sizes and is also taking its toll on low-contrast detail -- detail the red-leaf fabric of our test target images has become pretty soft and mushy. At 11 x 14, however, noise appears under control and not overly problematic from a quality standpoint.

ISO 3200 images really start to show the impact of the rising ISO sensitivity. There's an overall softness to lots of detail (and our red-leaf fabric swatch is nearly devoid of any detail whatsoever), but, by keeping sizes at 8 x 10 inches or below, you can still make some excellent prints with good detail and great colors.

ISO 6400 prints should be kept at 5 x 7 inches at maximum. Noise is quite apparent and really hurts fine detail at larger sizes.

ISO 12,800 images, unfortunately, are too soft and lacking in detail for us to comfortably consider usable for a print. However, for less critical applications, we'd be okay with a 4 x 6 inch print.

While the Canon G7X Mark II uses the same or very similar 20-megapixel 1-inch-type sensor as well as the same lens as the original Mark I model, it brings an all-new DIGIC 7 image processor to the table. Overall, it does a great job in the print quality department, offering about a print size larger than the G7X at the lower ISOs. At base ISO or ISO 200, the Canon G7X II is capable of crisp, colorful prints up to an impressive 24 x 36 inches. Even at ISO 800, the G7X II matches its predecessor with a very nice 13 x 19 inch print, and even a solid 8 x 10 all the way until ISO 3200. Despite its pocketable size, the G7X Mark II can still make nice, usable 5 x 7 inch prints up to ISO 6400. But at ISO 12,800, the Canon G7X II, like the original, captures images that are simply too noisy and lacking in detail to make acceptable prints.

About our print-quality testing: Our "Reference Printer"

Canon PRO-1000 Printer ImageTesting hundreds of digital cameras, we've found that you can only tell so much about a camera's image quality by viewing its images on-screen. Ultimately, there's no substitute for printing a lot of images and examining them closely. For this reason, we routinely print sample images from the cameras we test on our Canon imagePROGRAF PRO-1000 printer, which we named our "Printer of the Year" in our 2015 COTY awards.

The Canon PRO-1000 has a lot of characteristics that make it a natural to use for our "reference printer." When it comes to judging how well a camera's photos print, resolution and precise rendering are paramount. The PRO-1000's more than 18,000 individual nozzles combine with an air feeding system that provides exceptional droplet-placement accuracy. Its 11-color LUCIA PRO ink system delivers a wide color gamut and dense blacks, giving us a true sense of the cameras' image quality. To best see fine details, we've always printed on glossy paper, so the PRO-1000's "Chroma Optimizer" overcoat that minimizes "bronzing" or gloss differential is important to us. (Prior to the PRO-1000, we've always used dye-based printers, in part to avoid the bronzing problems with pigment-based inks.) Finally, we just don't have time to deal with clogged inkjet heads, and the PRO-1000 does better in that respect than any printer we've ever used. If you don't run them every day or two, inkjet printers tend to clog. Canon's thermal-inkjet technology is inherently less clog-prone than other approaches, but the PRO-1000 takes this a step further, with sensors that monitor every inkjet nozzle. If one clogs, it will assign another to take over its duties. In exchange for a tiny amount of print speed, this lets you defer cleaning cycles, which translates into significant ink savings. In our normal workflow, we'll often crank out a hundred or more letter-size prints in a session, but then leave the printer to sit for anywhere from days to weeks before the next camera comes along. In over a year of use, we've never had to run a nozzle-cleaning cycle on our PRO-1000.

See our Canon PRO-1000 review for a full overview of the printer from the viewpoint of a fine-art photographer.

*Disclosure: Canon provided us with the PRO-1000 and a supply of ink to use in our testing, and we receive advertising consideration for including this mention when we talk about camera print quality. Our decision to use the PRO-1000 was driven by the printer itself, though, prior to any discussion with Canon on the topic. (We'd actually been using an old Pixma PRO 9500II dye-based printer for years previously, and paying for our own ink, until we decided that the PRO-1000 was the next-generation printer we'd been waiting for.)
