It’s undeniable that, in terms of the tech and experience around its sensor, the Sony RX10 V is an excellent example of how far the camera industry has come in the last 10-ish years when compared to the Sony RX10 IV from 2017. But during that time, we’ve also seen a lot of discussion around how image quality has stagnated, and there’s no obvious difference between the V’s 20MP Type 1 (116mm²) stacked CMOS sensor and the IV’s.

There’s some truth to the idea that gains in image quality are coming slower these days, as much of the past decade’s progress has been more focused on performance in aspects like autofocus and readout speeds. That’s not to say there have been no advancements in image quality, but Sony hasn’t bragged about including them in the RX10 V. The only real way to find out, though, is to put it in front of our test scene.

Studio test scene

Our test scene is designed to simulate a variety of textures, colors, and detail types you’ll encounter in the real world. It also has two illumination modes, full even light and low directional light, to see the effect of different lighting conditions.

Unsurprisingly, the RX10 V performs very similarly to the RX10 IV when looking at its Raw images at base ISO, which is a good thing. It captures a good amount of detail, and at 88mm equiv., its lens actually holds up quite well compared to other cameras with Type 1 sensors and lenses with much less ambitious focal lengths. It also provides more detail with less noise than the Nikon P1000, which offers much more reach but uses a lower-res and much smaller 16MP 1/2.3″ (28mm²) sensor.

The RX10 V’s JPEGs are where the decade of progress becomes apparent. The colors are much more pleasing than those of the IV, with more natural skin tones, and the vibrancy of colors turned up where they were lacking, and turned down where they were overbearing. We also found this to be the case in the sample photos we shot with the V. Sony’s progress on this front has been slow and steady, but with so much time between the two models, it’s much more noticeable.

This class of cameras has never been the best pick for low light photography, the RX10 V’s Raws again look as we’d expect. Switch over to JPEG and it’s clear that Sony has upgraded the camera’s noise reduction to some extent, but in higher-contrast, more detailed areas, we’d be hard-pressed to tell its performance apart from its predecessor’s. However, it does outperform Panasonic’s similarly-specced (and now discontinued) FZ-1000 II from 2020 in this regard, and is significantly better at low light than the P1000.

Summary

The RX10 V doesn’t represent a massive shift in terms of image quality from its predecessor, nor, indeed, the RX10 III and RX10 II before it, which both used similarly-specced sensors. When those cameras were released, we called their image quality excellent*, and even these days it’s hard to argue that the pictures the RX10 V produces aren’t very good.

However, it’s hard to ignore that images from smartphones, armed with increasingly sophisticated computational photography tricks, have been getting better and better. Some models even include Type 1 sensors, too, edging in on even the highest-end enthusiast compacts, if only in terms of image quality and not shooting experience. Arguably, the RX10 V, with its massive focal range, is one of the compacts most insulated from this, as phones’ telephotos are often paired with much smaller sensors, and don’t offer anywhere near the level of reach. But it does raise questions about how the next versions of cameras like the RX100 will differentiate themselves.

Going back to the camera at hand, though, regardless of how much the RX10 V has or hasn’t improved when it comes to imaging, it’s still the best in its class… even if it is the only pupil remaining.

* – as long as you set aside their JPEG colors, which the RX10 V has thankfully greatly improved on.
