Sony Alpha A7R III vs A7 III: Battery lifeīattery life has never been a strong point on the Sony A7 series – until now. The A7 III's lower resolution means larger photosites and hence potentially less noise at higher ISO settings. The only difference is likely to be how the two cameras render their video footage. They also offer Super 35mm mode, HLG and S-Log gamma options. They share the same maximum 30p frame rate for 4K using the XAVC S format and a bitrate of up to 100Mbps. Both can capture full frame width 4K video using oversampling without pixel binning to maintain high image quality (the frames are captured at a higher resolution and then downsampled to 4K). There is no real technical difference in video specifications between these two cameras. Sony Alpha A7R III vs A7 III: Video features Images and menus should look just a tiny bit sharper, but in practice even the A7 III screen's lower resolution hits the point where the individual dots aren't really visible to the naked eye, so while the higher LCD resolution improves the user experience, it's hardly enough on its own to swing the decision towards the A7R III. Sony Alpha A7R III vs A7 III: LCD screenīoth cameras feature 3-inch tilting touchscreen displays, but the A7R III screen has a higher resolution of 1,440,000 dots versus 921,600 on the A7 III. Will you notice the difference? In isolation, probably not, but when you compare them side by side the A7R III's is just a little smoother and crisper. The A7 III and A7R III both have 1.3cm electronic viewfinders offering the same 0.78x viewfinder magnification, but the A7R III's has a higher resolution of 3.69 million dots versus 2.36 million dots on the A7 III. However, the camera and the subject must be stationary, and the images need to be merged in Sony's desktop image processing software. The result is slightly improved ultra-fine detail and reduced colour artefacts like moiré on fine textures and patterns, and its a system used for special high-resolution modes by other camera makers like Pentax, for example. In this way, it can record full-colour data for each photosite (pixel) rather than having to interpolate the colour information from neighbouring pixels, which is how sensors usually work. In this mode, the camera captures four images in succession, shifting the sensor by one pixel each time. This feature is unique to the A7R III and does not appear on the A7 III. Sony Alpha A7R III vs A7 III: Pixel Shift Multi Shoot In fact, the A7R III's higher resolution is likely to make any camera movement more obvious, potentially offsetting any gains. It seems unlikely you'll notice any difference in everyday shooting. The A7R III and A7 III both use Sony's 5-axis SteadyShot Inside in-body stabilisation, but where Sony claims a 5-step advantage with the A7 III it quotes 5.5 steps for the A7R III, due we believe to improved algorithms rather than any difference in the hardware.
