Panasonic Lumix S5 Vs Sony A7iii

by -78 views

The Sony A7 3 and Panasonic Lumix S1 are both 24-megapixel, full-frame mirrorless cameras — but other than that, they couldn’t be more different. The Sony takes a streamlined approach, with a slimmer and lighter design, while the Lumix looks and feels like a professional DSLR — bulky, but with much more direct access control. The S1 besides features a high-resolution mode that produces 96MP images, a significantly sharper electronic viewfinder (EVF), back up for faster retention cards, and more than advanced video features coming via paid firmware update.

Looking at the spec sheet alone, the Lumix S1 seems like the clear winner, but the A7 III all the same holds it own in existent-world use. It too costs $500 less, at just $2,000 compared to $2,500 for the S1. So which is correct for you? Here’south how these 2 cameras stack up.

While both the Sony A7 III and Panasonic Lumix S1 feature 24MP total-frame sensors, just the S1 has a multi-shot high-resolution manner. 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. This mode requires a tripod and a perfectly still subject area, then it’s all-time used for landscapes and even so-life scenes.

Other than that, both sensors produce remarkable image quality and have equal ISO ratings and excellent noise performance. If y’all don’t demand — or simply tin can’t utilise — the high-resolution mode on the S1, so there’s nix you’ll give up, paradigm quality wise, by going with the A7 III.

Lumix S1


While the numbers are close, the A7 III and the S1 take dissimilar limitations when it comes to high-speed continuous shooting. The A7 III tin can hitting ten frames per second with continuous autofocus, only without live view; the S1 manages a respectable 9 fps with alive view, only without continuous autofocus. The Sony slows to 8 fps to get both live view and continuous autofocus together, while the Lumix has to drop downward to half dozen. We’re giving the Sony the win here, although the difference may not be appreciable for all photographers.

Sony A7 Three


This is one area where the companies accept an inherently dissimilar approach. Sony uses on-chip phase-detection autofocus with 650 focus points spread over the frame. Panasonic uses its proprietary Depth from Defocus (DFD) system, which is based on dissimilarity-detection and split into 225 zones. While contrast detection is normally slower than phase detection, DFD speeds it up considerably; in our testing, it performed nearly equally to stage-detect systems almost of the time — but not all of the fourth dimension.

Nosotros’ve plant Sony’s autofocus to be more reliable, especially when it comes to tracking moving subjects. This has been made even better with the recent upgrade to Real-Time Tracking and Existent-Time Center AF, which added bogus intelligence-based focusing algorithms that make the A7 3 even more accurate. For its part, the Lumix S1 also has a subject field and center-detection way that works quite well, but, again, is slightly less reliable than Sony’south.

One potential do good of the S1’s contrast-detect autofocus is that information technology doesn’t crave special phase-detect pixels on the sensor, which, in theory, tin can allow for more than extreme exposure pushes in post without running into “banding” problems. In practise, we never noticed banding on the A7 Iii, so the real-world reward of this may be slim to none.

Sony A7 3


The Lumix S1 is by far the heavier and larger of the two, weighing in at over 2 pounds with the battery loaded. But if you tin can get over the weight, it offers the nigh functional and complete control layout of whatsoever mirrorless camera we’ve ever tested; the A7 3 is empty by comparison. Some of the S1’southward buttons fifty-fifty light up, making them easier to run across when shooting in low calorie-free scenes.

While both cameras claim environmental sealing, the S1 certainly feels similar the more durable of the two. It as well boasts the highest-resolution electronic viewfinder on the market, with 5.vii million pixels — over 3 million more than the A7 Iii. The 3.2-inch, 1000000-dot screen is also larger and college resolution than the Sony’s iii-inch, 921,600-dot screen. The S1 also has a large, secondary LCD on the top of the camera for displaying shooting settings.

Both cameras offer dual memory carte slots, only where the A7 Iii uses SD cards for both, the S1 gives you one SD and one XQD. Not merely are XQD cards faster than SD, but they are physically identical to even higher-speed CFexpress cards, support for which is coming to the S1 in a future firmware update.

Lumix S1


Both cameras employ v-axis sensor-shift stabilization to counter camera motion when handholding, and both do a very good job in still and video modes. The A7 Iii’south stabilization is rated for 5.5 stops of shake reduction, where the S1’s is skillful for half-dozen — or half dozen.5 when paired with an optically stabilized lens. It’south non a huge difference, but the Lumix takes another win hither.

Winner:Lumix S1


Both Sony and Panasonic are well known as video companies. Sony was one of the commencement to put 4K into a mirrorless camera, and Panasonic’southward GH series (built on the smaller Micro Four Thirds format) continues to nowadays us with some of the best video cameras you tin can purchase. The Lumix S1 isn’t really targeting that aforementioned audition, just it still packs a punch when it comes to video features. Fifty-fifty compared to the more expensive Lumix S1R, it has some pretty big advantages.

The S1 can shoot oversampled 4K/30  from the full width of the sensor, or 4K/threescore from an APS-C ingather. The A7 III tops out at 4K/30. Both cameras offer higher frame rates at lower resolutions for shooting in boring move.

The A7 III includes Sony’due south advanced South-Log colour profiles for greater dynamic range, but video is still limited to 8-fleck — whether recording internally or externally over HDMI. The S1 is too currently express to 8-scrap, unless yous shoot in Hybrid Log Gamma (HLG) which opens up x-bit output. A future firmware update will too bring Panasonic’s V-Log profile and 10-bit iv:2:2 recording to the S1; however, this will exist a paid update.

Winner: Lumix S1

Battery life

The Sony A7 III boasts i of the highest battery ratings we’ve always seen on a mirrorless camera at 650 exposures. That’s a fair margin higher up the Lumix S1’southward 380-exposure rating. However, the S1’southward poor performance here is likely thanks to its much higher resolution EVF and monitor, a tradeoff that may be well worth it for some photographers.

Mayhap because its engineers realized how much ability the S1 was going to consume, Panasonic also built in a special Power Save Live View Finder (LVF) Shooting mode, which somewhat mimics how a DSLR manages power. In this style, the photographic camera will get to sleep after a short time, but will leave some functions active, like the EVF eye sensor and shutter button. Battery life is stated as over 1,000 exposures in this fashion.

We’re notwithstanding calling this one in Sony’s favor, but whichever camera y’all choose, we recommend picking up a spare battery or two.

Sony A7 III


Sony’southward E-mount is part of a much more than mature organisation than the Panasonic S series, and thus has quite a few more native lenses available at this time. However, the S1 is built around the Leica L mount, which already has a collection of lenses that are fully compatible (but expensive — they’re made past Leica, after all). Additionally, Sigma has signed on to develop 50-mount lenses, with xi of their acclaimed Art-series lenses currently on the style. Of the 3 Lumix S lenses currently available from Panasonic, the S Pro 50mm f/1.4 is also one of the best 50mm lenses we’ve ever seen — of class, at $2,300, it should be.

Every bit of this moment, Sony is ahead in pure numbers, simply things will await a lot dissimilar over the side by side 12 months. This one is as well shut to call, but it’s a good idea to check if a system has whatever particular lenses you want before buying into information technology.


Picking an overall winner

The Lumix S1 is almost two cameras in ane. It’s a hybrid still/video machine with excellent depression-lite functioning from its 24MP sensor, and an ultra-high-resolution photographic camera capable of shooting 96MP images when you demand detail over speed. It is also the more durable and more professional of the 2, with an absolutely gorgeous EVF and expertly-designed control layout.

But the Sony notwithstanding comes out ahead in some areas, such as continuous shooting speed and autofocus performance. Information technology also is quite a bit less expensive, meaning yous tin can save some money to put toward a nice lens. If money is no object, we say become with the S1; it is one of the virtually forrard-thinking cameras nosotros have ever tested and is built with professionals in listen. But the A7 III is a great value at but $two,000; for enthusiasts on a tighter budget, it makes a lot of sense.
