Sony A7s vs A7R vs A7 comparison: 04 Continuous shooting and battery life
Smaller raw files and a faster sensor read speed enable the new A7s to match the A7 when it comes to burst speed.
Both the Sony A7s and A7 can hit a continuous shooting speed of 2.5fps, which increases to 5fps in Speed Priority mode.
The large file sizes of the Sony A7R mean that it’s capable of a continuous speed of just 1.5fps in normal shooting mode, increasing to 4fps in Speed Priority.
The Sony A7s uses the same NP-FW50 battery as the A7/R but puts in a better battery life performance.
Sony claims the A7s’s battery lasts for approximately 320 shots when using the viewfinder and 380 shots with the LCD screen when shooting stills.
That’s a marked improvement over the A7R and A7, which have been measured at around 270 shots (viewfinder) and 340 shots (LCD screen) according to Sony.
Disappointingly, for a camera that’s so focused on film-making, the Sony A7s doesn’t see quite the battery performance boost when it comes to continuous movie recording.
According to Sony, the A7s offers approximately 90 minutes of continuous recording – that’s the same as the A7R and 10 minutes less than the A7.
It’s a given that you’ll need a bag of spare batteries if you plan on doing day-long video shoots with the A7s.
