"We are now using the Sony a5100 for most projects (RGB and NDVI). It has a 24MP sensor with excellent dynamic range. It is also light weight and small enough for easy installation when used with the Sony 16mm or 20mm E-mount lenses."

Testing the GoPro 2

Posted on November 22, 2011 at 6:17pm 14 Comments

Ive been doing some testing with the new GoPro2 HD video camera. I bought it out of necessity after loosing my GoPro HD in flight :( But, having the HD jump ship was a blessing in disguise, because the new GP2 boasts some impressive features.

While shooting in 1080P, you can choose 3 different field of view (fov) settings: Wide at 170, medium at 127, and narrow at 90. Heres a video I made testing the different fov settings on a Skywalker foam airplane.…
