Hi Mark,
The drone is the Mavic 2. This comes in two flavours, the ‘zoom’ and the ‘pro’. The zoom has a zoom lens, with a focal length of 24-48mm. However it retained the original 12 MP sensor. The Pro, on the other hand, which is what I have, has a Hasselblad camera with a 20 MP sensor. On top of that the Pro shoots in 10bit, whereas the Zoom shoots in 8bit (8bit is standard with most prosumer cameras). This gives a much greater dynamic range.
Both of these cameras come fixed to the Mavic.
I could have just answered this question ‘Mavic 2 Pro’ but I’m a geek and enjoy answering questions like this 😉
