I have upgraded to A7RIII from Sony A6500 last year and before that I was using the A6500 for 4 years ever since 2017. I am really happy that I switched from Canon to Sony, because I am convinced that in the past 5 years Sony cameras are quite ahead of competition and countinue to be.
Set one of your Picture Profiles to use ‘HLG’ for the gamma setting, enable Zebra highlight warnings, and set the Zebra level to 100+. Now increase your exposure until the moment you first see Zebra warnings. These settings, where you first see a hint of Zebra warnings, is your optimal Raw file exposure – it will be the brightest possible, but counterintuitively (since you’re seeing the warnings), all highlights you want to capture won’t be clipped.
This may not result in the ideal JPEG but it should be of particular value for landscape shooters wanting to capture high dynamic scenes, as it allows you to forego exposure bracketing. We’re hopeful that this sort of method may point to the possibility of Raw histogram displays in the future, as opposed to the JPEG only histogram displays currently available.
I hope this review was useful and will help you in your decision for a camera body. If you are convinced that Sony A7R III is the camera for you I will be more than happy if you purchase it through the affiliate link I post below. I get a small comission from amazon for every item, purchased this way which will help me to continue to develop my website and make it even more useful and informative.
