Campare Olympus 12mm vs DJI 15mm

I think most people will probably end up using a few depending on the shot. Although its only 3 mm difference, its 2.4 crop or something so that 3 mm becomes more than 7-8mm when doing video so its around 28mm.

I would prefer to shoot in 24mm so I would love to see if a 9 or 10mm lens works, there is a MFT lens which costs very little and its 9mm, so I hope DJI support that, its less than 100g too and less than £100.
