Telephoto lens attachment
Is there a 20x telephoto lens attachment for the iPad?
The more telephoto you try to make the iPad, the more distortion it will cause and the more light you will need to keep the shutter speed up to prevent blur. Even 10x telephoto would not work well indoors on the iPad. What are you trying to shoot telephoto with the iPad?
You would probably be much better off with a compact camera that has a very long zoom like the Nikon P530: www.amazon.com/dp/B00IA9LUP2?tag=j1105-20
What about an option to turn my JVC GZ-EX515 into a webcam and leave it turned on? Is there an adapter that will take the mini-HDMI live out of that camcorder (with it's superior 38x optical zoom) and send it via thunderbolt or usb 2.0 to my MacBook Pro 17"? Then I'd get a large screen display of what my camera sees (which is why I was trying the iPad route) and I could instantly record video to Quicktime via the File / New Movie Recording command.
The disadvantage would be that I would lose direct control over the tilting and framing controls of the tripod-mounted iPad when monitoring at the MacBook screen.
You could also use something like the "BlackMagic Intensity Shuttle for Thunderbolt" www.amazon.com/dp/B007ZDHDRS?tag=j1105-20
There will be a slight lag on the preview with anything coming over USB or Thunderbolt to a Macbook.
