What does this mean: "Oh, and doesn't Canon have some kind of strong signing of an image that it comes from a person/camera? Maybe he should look into that, since it probably would help with chain of custody kind of thing for any evidence." Strong signing?Canon offers a Data Security Kit for some cameras, although a quick google suggests it's been cracked.
Yea, that's what I was referring to. Too bad to hear it's been completely cracked.
Oh, and maybe he should also get the GPS logger for the 1DX/5d3 if that's what he gets? That will help place the location of where he's shooting, and I believe even a digital compass to say which direction he's shooting in.
How far away does he need to do surveillance? This is the question. Because it determines the focal length of the lens. The ultimate low light telephoto is probably the 200 f/2 ($$$), but whether that is the appropriate focal length depends on the subject distance.
Pro-level tripods are big and easy to spot. Leaning the camera on something sturdy, perhaps with a bean bag, may be more practical. Or perhaps a monopod or a very short tripod/stand, like what some sports photographers use for their remote cameras.
The essentials are going to be:
- high res, high ISO camera = Canon 5D3, 1DX, 6D, (or Nikon D4, D800, D600?)
- wide aperture (f/2.8 or faster) prime or zoom with image stabilization, probably a discrete non-white lens (Nikon, Sigma) or white lens with an appropriate dark cover.
- practice focusing; practice steadying the camera.
Depending on the distance, a camera with quiet shutter mode may be of use (5D3, 6D). Also, it will be important to learn how to turn off / tape over anything that lights up on the camera.
The 200 f/2.0 would probably be overkill, although I'd love to own one
The 70-200 2.8 IS would probably do just as well, and be much cheaper as well. Add on the 2X TC, and you get the 140-400, even though it does go to f/5.6 it probably could still be usable at high ISOs like on the 5d3/1DX.
Great point about the big tripod. A beanbag on a car/wall or good quality monopod would be less obvious and easier to move around with. I'd also make sure to be using the lens-hood, even though it'll make it bigger and bulkier, it might help prevent reflections off of the front element of the lens. Most photographic lenses aren't made with the non-reflective coating like military/surveillance binoculars/scopes generally have on them.
