I've actually got a Sony Z1, and it's got a pretty darn good camera too.
I've got a real itchy trigger finger on the AS100. Only thing I wonder about is if the stabilization gets "Saturated" with too much shake. I saw some stuff that looked like that on the AS10. At some point it just can't deal with it and the image goes to hell, worse than no stab at all.
That Panasonic thing is interesting. Some things about that idea I like. Others, not.
Gary: I don't know the answer at that level. :)
@Rob -- Yes the AS100 XAVC supports upto 50mb/s, but all the cards I have are UCI (only have one at 40mb/s, others at 35! :) ) and was fincky with the hero3's.
Zeiss Lens == +Good. Much better than the GH or Contours I've used so far.
Funny thing is if sony ever releases the firmware, I'd ditch these and just fly a Z1S phone, the 21MP sensor has the specs to shoot 4K/30 (+LTE + GPS), otherwise it's off to the [unfortunately badly designed] Panasonic 4K action cam.
@Gary: With these small devices, you'd expect the former, but there's not much info on SteadyShot (duh, yep it's Sony)... could be the latter since the have that bioz engine thing.
Hi Rob, I understand 1080P 1920 by 1080 and I think I read the Sony is using a 19 mp sensor.
And I understand that the 1080P stabilized subframe that is extracted from the larger sensor, my question really was, is the extracted subframe actual 1080P pixel size on the larger sensor or is the subframe itself higher resolution than 1080P in which case roll pixel interpolation could be improved more easily without introducing artifacts about the roll center.
In any case, the video you included has convinced me that one of these is definitely worth giving a try in a quadcopter, even without a gimbal and perhaps just a little rudimentary vibration suppression.
Trying to find the manual for it so I can see how easy it is to use with a separate transmitter rather than WiFi.
Would like to use both as FPV camera and simultaneous 1080P Stabilized recording camera without WiFi.
Gary, these cameras definitely have more than 1080 pixels. They're probably 5-10MB or better.
Cliff, I thought the AS100 recorded at 50 Mb/s? Isn't that pretty darn high? Are you saying the Zeiss lens is good or not?
I think the gyros would be what is used to determine where the active 1080P subframe is extracted from.
It should do roll compensation too, but the calculations for displacing individual pixels around a roll center point are trickier and could result in some weird aliasing.
If the actual subframe is higher resolution than 1080P it could make pixel rotation more accurate.
Pitch and yaw are much easier, because they just define the current limits of the subframe.
It's the same method as Sony's action cam that Rob mentioned. I run an AS15 and AS100, color reproduction is noticeably better (aside from the Zeiss lens) than the GP3+Black, and activating OIS cuts FOV from 160 to 120 degrees--basically the same technique as the Bebop. Unfortunately the GP3 records closer to studio quality bitrates. I wish someone made a good gimbal mount for these cameras (aside from the custom 3D prints). Currently using a modified IMP 3 axis....
Parrot definitely took a different approach from DJI, as their 3 axis gimbal setup as it has limited movement in the yaw (+-20, hence not fully 3 axis capable) to simulate the same rolling motion--a mechanical version of the Bebop, but one would need to apply the IS in post software.
As for the antennas--makes sense for MIMO, but why not angle them away from each other 5 degrees (or more)? Also, they talk about 802.11ac, which is 5G only--what's the 2.4 being use for? (or it's 2.4 for control, 5.8 for video--which makes sense).
Maybe there are gyros on board to assist, but it's definitely not done with moving lenses. It's done by capturing a very wide angle picture, and then sub-framing it and manipulating the pixels.
@Daniel:
The stabilization is not done with active lenses. It is purely electronic. The system oversamples the video, locks on to key points in a given image, and then moves the framing around electronically. Sony is already doing this with their action cameras. The new AS100 looks like the perfect FPV camera. Check out the effect of the active stabilization vs. a GoPro:
This method actually has some advantages over active lenses. Because lenses cannot correct for roll-movement. I'm just surprised at how far behind Parrot seems to be. They probably just need to hire Sony to fix their system.
But I love that controller. Very nice setup. The claims that it can be used outdoors... I'll believe it when I see it. It's really small, and I can't see it withstanding more than 30 km/h winds.
+1 for @Emin Bu -
I already spend some money and time for the fist generation (4 of these), second and this one generation continues to be just expensive fragile toys, that can not be re-programmed and fixed easily - both on hardware and software side. Excluding iphone or android phone or tablet...
