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
Weight:45g
Battery: 700 Mah, 3.7 volts, 2.59Wh Watt

Resolutions:
UHD 24 2880×2160 16:9
QHD 30 2560×1440 16:9
2K 30 2304×1296 16:9
1080P 60, 30 1920×1080 16:9
720P 120, 60, 30 1280×720 16:9
VGA 240 640×480 4:3

----------------------------------------------------------
►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

DJI Mavic: frozen Lake at golden hour

We took the chance to skate this beautiful lake (last time frozen fully in 2009). The Dog (Charlie the Chihuahua) like the imperfect ice for he had more grip.


This is the 2nd part from this location. More RC Car slowmotion this time.

ImmersionRC Vortex 150 under the Bridge



Mini Review / Vortex Tips:
Batteries tested:
Like the Turnigy Nanotech 850mah 4cell the most,
Graphene 750mah 4cell is ok as well
Graphene 500mah is acro - but too short flighttime
Turnigy Bolt is not good!
1min you feel some extra punch - but then it's even worse then the Nanotech 850!

Foxeer Legend2 - is a nice option as HD cam here - but the quality should be better in 1080p. Weight of 45gr is ok for this little quad - but of cours it "feels" more sporty and lighter, more acrobatic without the payload. But where's the fun if I cant show it in HD here? :)
