Sony A7s with rangefinder lenses and Slog2 grading

This is the second video from the Sony A7s. I have already shot two projects with this camera and I was very happy from the results. Still, there are ma things to experiment with.

For this short video clip, I used the Voigtlander 15mm f/4.5 and Leica Summarit 35mm f/2.5 lenses. I also shot most of the footage using Slog-2.

About the lenses, the Voigtlander 15mm was a pleasant surprise, since it performs wonderful on the full frame Sony, despite its wide angle focal length. A lens for very special shots. The Summarit is also a great lens, and due to the full frame sensor, you can get close up shots with blurred background (for those instances you want it to).

Slog-2 is a great feature on the A7s which gives you a very wide dynamic range. Of course, you must have the expertise on shooting and grading when using this mode. I am still in the process of learning and so far, I have got mixed results. When shooting Slog-2, minimum ISO is 3200, which means you need strong ND filters in order to keep the proper shutter speed. Daylight shots may even require a 10 stops ND if you want to keep your aperture wide. I use a high quality B+W 110ND filter, but still I get a noticeable color shift, so there’s lots of work to do in post process.

When starting to grade Slog-2 footage, I apply a LUT in order to have a good starting point. Finding he appropriate LUT is tricky, and I am still experimenting. It’s also quite tricky to expose correctly when using this mode, a waveform monitor would be very helpful here, but I don’t own one, so I am trying to use the histogram (the washed out look on the screen is not helping much).

So, there are lots of things to learn. For now, here’s the video.
