I notice that it has a larger sensor but the figure quoted doesn't mean much to me.  How much different is it in real terms/specs than the Osmo Pocket 1 ?

Hello John Walker, thank you for reaching out and your inquiry about the sensor difference between the Osmo pocket 1 and 2. The Osmo pocket has 1/2.3"CMOS while the Osmo Pocket 2 has 1/1.7" CMOS. In millimeter that will be 1/2.3" = 6.17 x 4.55 mm, while the 1/1.7" = 9.50 x 7.60 mm. You can also refer to this link for the specifications comparison between the Osmo Pocket and Osmo Pocket 2. https://www.dji.com/products/com ... =brandsite&from=nav . Thank you.

This might help to visualise the sensor size comparison, it's slightly bigger than Original OP and it compares it with the sensor sizes up to dslr
