Aerial Camera Benchmark

Posted by mauricobain on April 22, 2011 at 3:14am

Hi everyone,

I want to build my own aerial photography kit, and now I'm in the stage of camera selection. I bought a Lumix DMC-FP3 but the result are not good, due to the low shutter speed of these camera. Now I thinking in buy a GoPro hero, but first I want to know if anybody has a benchmark to select a camera to civilian UAV application.

So, Have You any ideas?

    Read up a bit about cameras.  Photography people tend to speak in F stops (powers of 2 additional light or light sensitivity).  The minimum aperture on your camera is F/3.5, or one and a half stops ((2^0.5)^1.5) 'slower' than an F/2.0 lens.  This means that the lens focuses less light on the sensor than a faster lens - the extreme of this being a pinhole camera.  On the other hand, a bigger sensor means more sensitivity to light - a sensor twice as large will give one stop better response.  Shooting wide open, these two factors will give you a first approximation of how much faster you can shoot with a given lens/camera for about the same dynamic range and noise level.

     

    Three recs:

     

    • We use the Canon SD4000 point and shoot because it's cheap, has manual control, takes lots of pictures quickly, and is *just* fast enough that we don't worry about blur in open sunlight from a Mikrokopter (F/2 1/200s).

     

    • The Sony NEX-C3 caught my eye recently because it's lightweight, it's got a sensor that is 3.5 stops larger, though the ideal lens (a 16mm f/2.8) is a stop slower, and it's barely larger than a point and shoot camera.

     

    • Look at Contour as closely as GoPro.

    Don't know about benchmarks, but you won't better the Go Pro 1080p for picture quality...
