It also boasts the highest-resolution electronic viewfinder on the market, with 5.7 million pixels - over 3 million more than the A7 III. While both cameras claim environmental sealing, the S1 certainly feels like the more durable of the two. Some of the S1’s buttons even light up, making them easier to see when shooting in low light scenes. But if you can get over the weight, it offers the most functional and complete control layout of any mirrorless camera we’ve ever tested the A7 III is empty by comparison. The Lumix S1 is by far the heavier and larger of the two, weighing in at over 2 pounds with the battery loaded. In practice, we never noticed banding on the A7 III, so the real-world advantage of this may be slim to none. One potential benefit of the S1’s contrast-detect autofocus is that it doesn’t require special phase-detect pixels on the sensor, which, in theory, can allow for more extreme exposure pushes in post without running into “banding” problems. For its part, the Lumix S1 also has a subject and eye-detection mode that works quite well, but, again, is slightly less reliable than Sony’s. This has been made even better with the recent upgrade to Real-Time Tracking and Real-Time Eye AF, which added artificial intelligence-based focusing algorithms that make the A7 III even more accurate. We’ve found Sony’s autofocus to be more reliable, especially when it comes to tracking moving subjects. While contrast detection is normally slower than phase detection, DFD speeds it up considerably in our testing, it performed nearly equally to phase-detect systems most of the time - but not all of the time. Panasonic uses its proprietary Depth from Defocus (DFD) system, which is based on contrast-detection and split into 225 zones. Sony uses on-chip phase-detection autofocus with 650 focus points spread over the frame. This is one area where the companies take an inherently different approach. We’re giving the Sony the win here, although the difference may not be appreciable for all photographers. The Sony slows to 8 fps to get both live view and continuous autofocus together, while the Lumix has to drop down to 6. The A7 III can hit 10 frames per second with continuous autofocus, but without live view the S1 manages a respectable 9 fps with live view, but without continuous autofocus. While the numbers are close, the A7 III and the S1 have different limitations when it comes to high-speed continuous shooting. If you don’t need - or simply can’t use - the high-resolution mode on the S1, then there’s nothing you’ll give up, image quality wise, by going with the A7 III. Other than that, both sensors produce remarkable image quality and have equal ISO ratings and excellent noise performance. This mode requires a tripod and a perfectly still subject, so it’s best used for landscapes and still-life scenes. This uses the stabilization gimbal to shift the sensor slightly between images, taking eight exposures in total and combining them into a single photo with a resolution of 96MP. While both the Sony A7 III and Panasonic Lumix S1 feature 24MP full-frame sensors, only the S1 has a multi-shot high-resolution mode. 693-point hybrid phase-detection contrast AFĤK/30p, 4K/60p with 1.5x crop, HLG (V-Log via firmware update)Ģ.95 inch, 921,00 dot tilting touchscreenĪvailable body only or with 24-70mm f/3.5-5.6
