Design and usability · Screen and viewfinder · Auto focus · 5-axis stabilization One of the main differences between these two cameras can be found here. Both have a 35mm sensor with BSI (Back-Illuminated) technology, but the resolution is different. The A7 has 24 MP and a low-pass filter, while the A7R III comes in 42 MP and without AA filter. Both the a7III and a7RIII can record 4K video at up to 30 frames per second and 100 Mbps with XAVC S compression.
ISO performance is very similar up to around ISO 1600, but from ISO 3200 onwards, the a7R III shows more noise than the a7III.
Is the a7III 2021 worth it
If you’re already lugging around photographic equipment or reversing lenses, the difference in size is negligible, but if you’re planning to use the Sony A7III as a “grab and go” camera for street photography, its size is a salvation. It is worth noting that the small rubber eyecup that attaches to the EVF, unfortunately, has the habit of coming off. I’ve been using the A7III since its launch and with the release of the Sony A7IV, hobbyists around the world are starting to wonder if the A7III is still a good camera or if it’s a model that should be left in the past. If you’re already invested in the Sony lens portfolio or don’t have a collection that will be out of date for the A7III, I would highly recommend you buy one.
what’s the difference between Sony A7R and A7S and A7
The A7R does not have a low-pass filter to further enhance its fine detail rendering capabilities, while the A7S does have one to optimize quality in video mode. The A7S has other professional settings you won’t find on the R model, including timecode, manual audio control, zebra and marker settings. In most cases, this won’t be a problem, but potential A7R users should be aware of this if they want to do some demanding post-production. Unfortunately, you’ll have to live with the shutter shock on the A7R, as the camera doesn’t have an EFCS (Electronic First Curtain Shutter) mode that would solve the problem, as the important vibrations are the ones generated by the first curtain.
Which is better a7ii or a7III
The a7II battery is suitable for around 350 shots, meaning photographers will need a bundle of spare parts to get them through the day. Although this series is not aimed directly at videographers — that’s the range of the A7S series — the film performance has been updated in the a7III. When all three cameras were upgraded to the Mark II generation about 3 years ago, the a7II fell short of the pace of its siblings on certain specifications — particularly autofocus offerings — which was reflected in the pricing. This has been slightly improved on the a7III and now allows a correction of 5 f-stops compared to 4.5 f-stops on the a7II.
