Plastic HD Video: Pentax K-x and the DA 35mm f2.4

I just got the “Plastic Wonder”, the DA 35mm f2.4 prime from Pentax. This is one of their inexpensive primes. It’s very much like the DAL lenses, so much so I’m surprised there isn’t an “L” in the model. As much of the lens as possible is made of plastic. Just the glass, contacts and focus mechanism. Even so, the images this lens can produce helps make it one of the best dollar for dollar buys in the Pentax line up.

The K-x can shoot 24p 720p video, but it lacks a lot of control many other video capable DSLRs have. One of the things I was keen to do was to try the new lens with video. I shot a few clips of my kids fish. I took the AVI files into Final Cut, threw on some silly sound effect, and desaturated the clips just a bit.

At f2.4 the DOF is razor thin, and I need more practice tracking focus but it’s not bad for a $500 HD rig.
