Foxeer Legend 2: SCALE FAIL! VLog style review and compared to Legend1, Runcam2, SJ M20

I've waited 2 month now for a new firmware which should have better scaling. Last FW from 27.12.2016 did not help here.
Instead they now gonna release the Legend3 (March) and make me look like a fool releasing the review for the Legend2 so late :)
I think the hardware wasnt fast enough to downscale properly. Legend1 didnt have to downscale (since it is native 1080p).



IMPORTANT - see additional images for quality comparison


►Legend 2:
- like the low weight (45gr), the handling, build quality,
- rubber shell for protection
- cables, RC channel switch
- lost cam alert!
- wifi app is ok, but neccessary to change settings - small display preferable!
- really sharp in highest quality (2.5k), but terrible downscaler

Sensor: 12 megapixel Sony Exmor R BSI CMOS back-illuminated
CHIP: ? didnt find specs to the chip - and this maybe the cheap compromise here (which cant scale well)
Lens: FOV155°, F2.8, 7G optical glass lens
Length x Width x Height 67mm x 39mm x 17mm

►Runcam 2: yes I know - it's not focussed properly. My bad!
----------------------------------------------------------
►DJI Osmo Mobile:
OK, I saw it (too late) half my gimbal shots with S7 in 4k were out of focus. Happens to me sometimes with the phone. Needs extra care!
if you buy the R0de VideoMicro (50€, very good!) you get the TRS cable (which is NOT compatible with PHONEs - but rather with the original Osmo cam).
I found this adapter cable from "TRS" to "TRRS":
1x Rode SC7, Adapterkabel von 3,5mm TRS Klinke auf 3,5mm TRRS Klinke, Anwendungsbeispiel: Rode VideoMic Go, VideoMicro (oder ähnliches Mikrofon mit TRS Ausgang) zu iPhone oder iPad
