Sony has been ahead of the curve for a long time and now everyone is trying to come after their market share. I don’t know if the Panasonic S1R/S1 will be tempting enough, but Apotelyt had put together their comparisons. Now that the Panasonic S1R and Panasonic S1 are in their comparison tool you can see how things stack up on your own. You can follow it’s launch at 43addict if you’re interested. The official announcement is expected within the next 24 hours.
Advantages of the Sony Alpha A7R III:
- Better video autofocus: Features on-sensor phase-detection for more confident movie autofocus.
- More compact: Is smaller (127x96mm vs 149x110mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 248g or 28 percent) and hence easier to carry around.
- Easier travel charging: Can be conveniently charged via its USB port.
- Faster data transfer: Supports a more advanced USB protocol (3.1 vs 3.0).
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
- More heavily discounted: Has been on the market for longer (launched in October 2017).
Arguments in favor of the Panasonic Lumix DC-S1R:
- More detail: Has more megapixels (47.3 vs 42.2MP), which boosts linear resolution by 6%.
- Better video: Provides higher movie framerates (4K/60p versus 4K/30p).
- More detailed viewfinder: Has higher resolution electronic viewfinder (5760k vs 3686k dots).
- Easier setting verification: Features a control panel on top to check shooting parameters.
- More detailed LCD: Has a higher resolution rear screen (2100k vs 1440k dots).
- More flexible LCD: Has full-flex screen for odd-angle shots in portrait or landscape orientation.
- More solid recording: Has a full-sized HDMI port for a sturdy connection to an external recorder.
- More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
- More modern: Was introduced somewhat (1 year and 3 months) more recently.
Comparing the Sony a7III and Panasonic S1 is also very interesting. I can’t wait to see Sony’s 5760k EVF on a future Sony camera like the Sony a7SIII or upcoming professional APS-C camera.
