The Sony FS700 was a huge success, largely due to the fact that it was the cheapest and easiest way to shoot slow-motion. Now, almost four years later, Sony is releasing the successor to the F700, the FS7. To the naked eye, it looks very similar to the FS700, but there are some notable differences.
The biggest difference between the Sony FS700 and FS7 is that the FS7 shoots 4K internally. The FS700 does have a 4K capable sensor, however to shoot in 4K you would need an expensive external recorder and possibly a hardware upgrade. Straight out of the box the FS7 can start shooting 4K.
While it seems the FS700 may have an advantage over the FS7 because it can shoot 240fps while the FS7 maxes out at 180fps. There is, however, a difference in the way these two cameras shoot slow-motion.
The FS700 relies on a buffer system, when the camera is in S&Q mode, it is constantly recording & erasing (buffering) everything it is seeing to it’s internal memory. When you’re using the camera in start trigger mode, you press the record button and it immediately starts to fill that buffer up with whatever it is seeing, and then once it is full or you press the record button again, you record what the camera has saved to it’s internal memory to the SD card. This buffering system can be useful, especially with the End Trigger mode setting. Because the camera is constantly recording and erasing, End Trigger mode allows you to press record after the event you wanted to record has just happened. The FS700 will the record the last 8 seconds of video that it was buffering to your SD Card.
The FS7 doesn’t record slow-motion that way at all. It basically just records slow motion as soon as you hit records. No internal buffering, no recording the event after it happens. This is advantageous because unlike the FS700, the FS7 will allow you to record slow motion for longer. You’re really only able to shoot about 8 seconds of live action per slow motion burst. The FS7 will essential let you record slow motion for as long as you SD card can hold.
