[Update: There is a Freefly video suggesting that the Movi can handle quite a bit more weight than I assume below, so my weight concern may be overstated. However, it doesn’t matter because weight turned out not to be an issue.] I think that a key issue when it comes to using an RX0 with the Movi is to keep the weight at or below the weight when using a Moment Wide Lens, which we know works with the Movi counterweight. The weight for that setup with an iPhone 8 Plus is: iPhone 8 Plus: 202g Moment Photo Case for iPhone 8 Plus: 46.4g Moment Wide Lens: 76.2g Total: 324.6g or 11.45 oz In comparison, this is the RX0 weight as I plan to test it over the weekend: AndyCine gimbal adapter for the RX0: 149g RX0 camera including battery & storage card: 110g Total: 259g or 9.14 oz. So it appears that I'll be under by roughly 65.6g or 2.3 oz. I use 30.5mm neutral density filters with the RX0, so a bit of room is helpful. The AndyCine adapter is this product: https://www.amazon.com/gp/product/B078TGXH91/ref=od_aui_detailpages00?ie=UTF8&psc=1 I sometimes use the RX0 with a 5" 4K recorder/monitor, so I also want to try using the RX0's HDMI port as part of the Movi setup. For this, I've ordered a Freefly Systems HDMI cable that the gimbal sales people at my local camera store (B&H) tell me is particularly flexible: https://www.bhphotovideo.com/c/prod..._910_00187_lightweight_right_angle_micro.html I should have all of the components necessary to test this tomorrow and will follow up on how well it works. My main concern is whether the Movi's arm will show in the footage, but the RX0's 24mm equivalent lens, which is quite a bit narrower than a GoPro lens, should help with that.
