Please help me make this decision. I need a better bridge camera for travel. Landscapes, street scenes, zoom shots, people...travel photos. The RX10 iii or iv both offer great IQ, speed, video, 4K, Zeiss, 25x zoom. However the iv is at least $200 more than the iii. So, the question: Is the iv $200 better than the the iii?
Both cameras cost more than a good bridge camera should cost. Is this where bridge cameras are going?
Thanks for your opinion.
The main difference are the AF options. The IV acquires and tracks better, and the accuracy has been improved, due to the hybrid AF and the huge number of AF points. The III uses only contrast detect AF, and only has 25 focus sensors. The IV adds 315 phase detection AF sensors, and a faster processor.
Bigger buffer, faster frame rate, shorter blackout between shots in at the high frame rate, etc all contribute to much snappier "feel".
You can read about the differences here:
https://mirrorlesscomparison.com/preview/sony-rx10-iii-vs-rx10-iv/The ISO range is identical on both cameras, but the newer processor allows for slightly better high ISO performance. I have used mine up to 3200 ISO. It wasn't terrible, but for practical purposes, ISO 1600 is the highest I would use.
Yes, in my opinion, the difference is well worth the difference in price.
Do check out the free copy of Capture One Sony Express, and if you like it, upgrade to the Capture One Pro Sony. It is really good and does a better job than DXO, Adobe software and On1.
