Despite the new sensor design in the RX100 IV, the resolution remains the same between these two models. The fine detail resolution is therefore very similar, though we can see slight differences, especially in the mosaic crop, with the Mark IV appearing a bit sharper.

Another pairing of 20.2MP cameras with 1-inch-type sensors seen here. JPEG processing differences are apparent when looking at the top bottle crop. Detail overall is great from both cameras at base ISO, though the mosaic detail from the Canon looks ever-so-slightly more natural. The fabric swatches look very similar, though the Sony handles the pink swatch a bit better.

The difference in resolution between these two cameras is very apparent in this comparison. Detail is quite good from the 12-megapixel 2/3-inch Fuji X30 sensor, but the Sony shows just what's capable from a larger, higher-res sensor.

Here we have another 20MP match-up, and detail resolution looks quite impressive from both cameras. The newer 1-inch-type sensor in the Nikon displays much better detail than we've seen in the past. The Sony edges out the Nikon, however, with crisper, sharper detail, and also handles the tricky fabric swatches a bit better.

Again we have a more striking difference in resolution (20.2MP vs 12.8MP), and while both do very well in their respective crops, the Sony RX100 IV shows more fine detail across the board by comparison, though on its own, the LX100 does a great job with fine detail here. Detail in the mosaic crop from the Panasonic is very clean and more natural-looking, while the Sony appears a bit more over-processed here by comparison.

Bumping up the ISO, we see a subtle but interesting change. The Mark IV, in the bottle crop, shows a bit more noise, but at the same time allows slightly more detail to come through than its predecessor. The same can be said ever-so-slightly on the mosaic crop. However, both cameras struggle with resolving detail in the fabric.

The large resolution difference really makes this a difficult comparison. The Panasonic has a much lower resolution, but looking closely, you can see it has very well controlled noise at this higher ISO and also a very good amount of fine detail for this image resolution. The Sony, on the other hand, by comparison appears a bit softer and less detailed.

At ISO 3200, the RX100 IV shows slightly more noise again, like in the ISO 1600 comparison, and subsequently, shows a bit more fine detail in the mosaic crop than the RX100 III. Both cameras, however, really struggle with the fabric swatches, particularly the red one.

Noise is pretty apparent here from both cameras, and really impacting fine detail. In the mosaic crop, in particular, the Sony just edges out the Canon with slightly more visible fine detail. Both cameras really have a tough time resolving any recognizable detail from the red fabric swatch, though the Sony handles the pink fabric slightly better.

Detail comparison. Comparing high-contrast detail, we can see that most, if not all cameras do well at base ISO. The Fuji X30, with the smallest sensor of the bunch, pulls up the rear with slightly less crisp fine detail. As the ISO increases, however, differences in resolution performance appear. The Sony RX100 IV definitely shows visible noise and softer detail at the higher ISO levels, but it's more or less on-par with the other 20MP 1-inch-type sensor cameras here, though the Nikon J5 struggles more at ISO 6400. Additionally, the Canon G7X resolves slightly more super-fine detail at the higher ISOs than the Sony cameras. The real standout, however, is the larger-sensored Panasonic LX100, which produces lots of fine detail all the way up the ISO scale, despite having a lower megapixel count than the competition.

 

Sony RX100 IV Print Quality

Very good 24 x 36 inch prints at ISO 80-125; a solid 11 x 14 at ISO 1600; a good 5 x 7 at ISO 6400.

Canon PRO-1000 Printer ImageISO 80 to 125 images look very good at 24 x 36 inches, with crisp detail and rich color reproduction. Print sizes up to 36 x 48 inches are fine for wall display purposes here.

ISO 200 prints also look good at 24 x 36 inches, with only a minor amount of softening occurring in fine detail such as our mosaic tile area of our Still Life test target.

ISO 400 yields a nice 20 x 30 inch print. There is a trace of softness in our target red swatch and a mild amount of noise in flatter areas, but nothing major.

ISO 800 images require a reduction in size to 13 x 19 inches in order to pass our "good" grade. Even at this size there is still a trace of noise in flatter areas of the target and a common softening in our tricky red fabric swatch, but otherwise a solid print overall.

ISO 1600 prints reveal too much noise at 13 x 19 inches to call good, but the 11 x 14 inch prints tighten up nicely, so we advise keeping it at or below that size here for your critical printing.

ISO 3200 delivers a good 8 x 10 inch print. There is no contrast detail remaining in our target red swatch, but that's very typical for all but larger sensors by this ISO.

ISO 6400 yields a good 5 x 7 inch print, which is not bad at all for a 1-inch sized sensor, and the print shows a good amount of overall color saturation remaining.

ISO 12,800 prints a good 4 x 6, which yet again is not bad for this sensor size.

The Sony RX100 IV delivers print sizes that we expected, right in line with the predecessor model, the RX100 III. The Mark IV's big updates were primarily centered around the new stacked sensor, which is a technology more for improvements in speed than image quality. If you're debating between the two, the image quality difference is not a factor in terms of available print sizes.

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.)
