First i'd like to thank all of you for your comments regarding our first post (http://diydrones.com/profiles/blogs/fpv-gimbal-for-zoom-camera?xg_source=activity). Your comments helped us with technical issues and got us really positively motivated.
Theory became reality
We have just finished the first week of tests and we are more than happy to share our results with you. We are now flying FPV with 3 axis gimbal with a 27x zoom, so lightweight, that it can be easily attached to Iris+ or Phantom, or a SkySurfer1400 plane. And the experience is amazing. It is very natural to fly with the zoom and it gives you a lot of freedom. It really feels, that this is a must have feature in all FPV models.
More work to come
The gimbal gives some minor vibrations when the camera is at full zoom, but we plan to improve it until we get the maximum quality. We still see room for improvement, and it's only our first week of tuning :).
When we hit the maximum level of mechanical stabilisation we plan to test a digital camera with zoom, with a software stabilisation. The quality of video can improve dramatically by replacing camera to a better one.
-27x zoom (3,5mm - 94,5mm)
-PWM zoom control (from receiver)
-1/3'' SONY 960H EXview HAD CCD II (700TVL)
-RTF weight 360 grams /0.79 lbs (including camera, autofocus lens, brushless motors, a dedicated dampening plate and gimbal controller)
-3S Voltage input.
Jacob and I thought about building few sets for you to test. If you're interested just email us (firstname.lastname@example.org).
