I'm building a aerial photography system with a Sony mini-DV camcorder. The sony has the ability to control zoom and on/off through a lanc connection, but I don't know of any wireless controllers. Does anyone know how I can zoom my camera and turn it on and off while it is up in the air?

Thanks,
Dino

I usually use the front to back motion of my right stick to zoom in and out.


Smart guy huh?

I've got one of those zoom controls for my Canon - never used. Wanna buy it?

Anything that requires a zoom should just be flown closer to! You'll end up with a better shot probably too.. not sure if I'm right but if you wanted to zoom you'd have to use AF or an auto mode and you might end up with some blurry shots!

Thanks for your help guys. You're probably right, zooming in on a shot will probably just make for a blurry and jumpy video; it probably makes more sense to have the camera operator tell me to move closer or further away...That just leaves the on/off function, but I guess I can live with a little wasted tape and take it out in the editing phase.

Thanks!
Dino

The links above will show you how to turn the camera on and off in the air. That remote works for the Sony camcorders as well. I'm using one for a still camera but instead of hacking it I put a micro servo on it. It will allow you to start and stop the video, zoom in and out(I don't recommend this either), and I think turn the power on and off.

Sony Video Controller

I bought one of Angelos' great opto-isolators and wired it directly into a Jessops generic LANC controller I got from Keene Electronics (code: JLR). Now I can operate any camcorder with LANC support. With all the radio signals flying around our aircraft I always feel more comfortable with a hard wired remote rather than IR.
Horses for courses I guess.

Good luck

I agree it is better to fly closer but it can't be done in some cases. When I took this photo I didn’t want to risk flying over the racetrack or spectators. So I flew at an empty field around 200-300m back and probably 200-300m high with (I am guessing) 4x Zoom. Although the photo lacks a little bit on sharpness I think it is great considering how it was taken.

By the way, I am planning to design a LANC controller but I can’t promise on a date at this time as I have lot’s of other things to finish first.

morph, I'm very glad to hear you like the e-switch!

morph, I am actually planning to use the same hardware as my autopilot. This is designed to be a generic computer with lots of servo inputs and outputs and very flexible IO. It was designed to have capability for LANC so I only need to write new software for it. I just need to find the time and get myself a Sony camera.
