People shooting 4k 120fps are probably shooting on the a7siii, which is a different camera. You’ll need to get an a7siii if you want to shoot 4k 120. The a7iii can only shoot 1080p 120. Mine only does 1080 at 100fps. I’ve noticed this on YouTube vids as well when Americans mention the capabilities of the A7iii. 3. Number Of Shots. For Number of Shots, calculate how long you want the sequence to be and multiply by 24 (you’ll export the final video at 24 frames per second). So, for a 30-second timelapse sequence, 30 * 24=720. Note, the camera automatically calculates how long it will take to shoot the sequence and shows it at the bottom of the screen. Price Comparison.

Continuous Shooting. Depending on the Sony Alpha model you own, the continuous shooting speeds will differ. Currently, the A9 and A9 II are the fastest at 20fps, whereas older models such as the original A7 only goes up to 5fps. What’s more, older cameras may lock focus on the first frame when using the fastest speed. The A7 III offers 93% phase detection point coverage across the image area in full frame mode whereas thee A7R IV covers 99.7% of the height and 74% of the width. 5. Eye AF in movie mode. With the release of firmware 3.0 in April 2019, the A7 III received an important update: enhanced ‘real-time’ Eye AF. Continuous focusing is quite a bit better with the A7RII, and it can be more versatile - although the A7II is okay within its limits. Also, the A7RII has much better low light capability (in the S35 video mode) than the A7II. Aliasing and Moire on A7II is pretty bad, like Canon bad, in crop mode it is even worse Sony a9.
