First daylight for the Canon TX1


First flight for the Canon TX1 (4 min 3 sec)


So after 5 hours of preparation, finally got the first daylight HD in. What really stands out is the Canon's high shutter speed. Blades appear to spin backward. The copter is always sharp.

At high shutter speeds the 1/2.5" CCD's all bloom when shooting white objects in front of dark backgrounds. The solution is to use low shutter speeds and stop down, but the Canon doesn't have manual shutter speed for video. It uses the highest shutter speed possible.

The Sanyo HD2 has manual shutter speed, so it wouldn't have this problem.

For the Canon's first coverage, had upgraded PWM code and a new 3.3Ah battery. Got 15 min before wind became impossible to take off in without flipping over. The ESC wouldn't work with the PWM at 60Hz. Needed 75Hz.

Notice the yaw oscillation. The PID loop must be recalibrated for the new PWM period.

I have used both cameras. This is from a quality
standpoint. Your opinion may rely more on usability
which I have no opinion on. This was the first Canon
I ever saw which had lower quality output than its competitors.
Would have probably gotten the Sanyo, based on 1 month of usage.


Canon TX-1
-------------
convenient mounting
cheapest HD cam with zoom
best stabilization
no macroblocking in fast motion

mosquito artifacts
heavy 9oz
blurry lens
no manual shutter for video
lousy color in bright light because of high shutter speed
\exposure lock for video doesn't work




Sanyo HD2
-------------
sharp lens
better color in bright light because of ND filter
long recording time
light 8oz
smarter autofocus


30% more expensive
macroblocking artifacts in fast motion
inconvenient mounting
lens cap falls off
no exposure lock
lousy stabilization

As a consumer, you won't get good quality from either camera. You still have to be intimately involved in the quirks of the autofocus, shutter speed, f-stop, iso, ND filter to get anywhere with these cameras. Consumers should stick to the low definition pencams for a bit longer.
