Our previous comparisons of Sony a7, which are against Sony a7II and Sony a7R, are already quite interesting, but this time, the task is even more difficult. This time, we are about to put Sony a7 and Sony a7S against each other. What makes this product comparison difficult is that each of the models have each own strong points and advantages, as well as disadvantages. However, worth a note, Sony a7S is a lot more expensive than Sony a7. The gap can even reach several hundred dollars. Which one should you choose? Let us see!
Even when comparing the output quality, each of the models has each own strengths and weaknesses. Sony a7 boast a much higher maximum resolution, featuring a 24 MP full-frame CMOS sensor. Sony a7 also has a considerably higher number of focus points with 117 focus points. Furthermore, Sony a7 has higher color depth and dynamic range. As a comparison, Sony a7S is only armed with a 12 MP sensor and 25 focus points. Therefore, especially for still images, Sony a7 can capture larger, sharper, and more detailed pictures than Sony a7S. The color vibrancy can be better as well. (Take a look at Sony a7 vs Fuji XT1, for looking another comparison option)
On the other hand, Sony a7S boasts powerful video performance. While Sony a7 is pale with 1920×1080 vids, Sony a7S can record vids in 3840×2160 resolution! Furthermore, Sony a7S features extremely higher maximum ISO, with 409600 of max ISO and 3702 of low-light ISO. Sony a7 only has 25600 max ISO and 2248 low-light ISO. Additionally, Sony a7S also has significantly larger pixel area than Sony a7. These points do not necessarily make Sony a7S’s still images as good as Sony a7, but they certainly boost Sony a7S’s video quality to a very high level. As it can record slow-motion videos as well, Sony a7S is extremely versatile for video recording. It can do well for various purposes, including recording videos in a dark environment as well as perpetuating fast-paced actions and sports.
Both models support Wi-Fi. They both have articulating screens, external flash shoes, electronic viewfinders, also microphone and headphone ports. Both have rugged, weather-proof bodies.
