I did not bring any tripod or extra microphone, as I would be standing in a crowd of people, and needed to be fairly agile.
Most of the time, I used the lens in the longest setting, at 300mm, and stopped down the aperture a bit to f/6.3. I could do this at ISO160, the base ISO, and still have a healthy shutter speed of about 1/500s, even when dialing in about +1/3 to 2/3 of exposure compensation. I needed the exposure compensation, as I was mostly shooting into the sun, or close to the sun.
Here I have edited the footage into a video stream of about three minutes with some of the footage:
I used Kdenlive to edit the stream, and I added a bit of post process image stabilization to the video. This was needed, even though I used the OIS feature of the lens. Perhaps I would have been able to go without the extra image stabilization had I used a tripod.
Some things to note about the video:
- There is quite clearly still some vignetting, even though I did stop down an extra 1/3 of an aperture stop.
- You can see the lens OIS working, as the brightest central disc area moves about in the frame.
- The focus is mostly ok. Some times, the camera loses focus for a short period, but it is not a big problem. I had the AF-S mode selected.
- The sound is not very good. An external microphone would probably have improved it.
- You can see the evidence of rolling shutter distortion. Here is a frame from a video, where the helicopter blade is bent due to the rolling video shutter:
When using the mechanical shutter for still images, though, there is virtually no rolling shutter effect:
This is because the mechanical shutter travels faster than the electronic line by line readout of the sensor is.
