Here’s a compilation of footage from this years winter trip to Norway. This was all shot with the PXW-FX9. Mostly with sony lenses and autofocus. The AF was great for following the dog sledding. The camera performed really well and did a great job of capturing what was a very faint Aurora display in between cloud banks.
The daytime footage was shot using S-Log3 in CineEI. I didn’t expose any brighter than base, so used 800EI or 4000EI. I used the viewfinder display gamma assist rather than any LUT’s as I know I can use gamma assist no matter what frame rate I shoot.
The Aurora was very faint, barely visible to the naked eye, so I had to shoot using a 32 frame slow shutter (the equivalent of about 1.3 seconds at 24fps). I then used interval record with a 2 second interval to create the timelapse Aurora sequences. As there were no dynamic range concerns I chose to shoot using the default S-Cinetone settings in custom mode so I could see exactly what I was getting. I was amazed at how many stars the camera picked up with such a short exposure, a sure sign of how sensitive the camera is. For the Aurora I used a Sigma 20mm f1.4 lens with Metabones speed booster and 4K s35 scan. I felt that the extra stop of light gained from the use of the speedbooster was better than the slightly lower noise that would have been present if I had used the 6K FF scan. I did also try S&Q at 1 frame per second with the shutter off to see how this compared to the slow shutter. The S&Q was much noisier, the cameras built in NR seems to work particularly well with the slow shutter function, so if you need a long exposure on the FX9 I recommend slow shutter and interval record over S&Q at 1 frame per second.
For the sunset shots I made use of the variable ND filter, set to auto to control the exposure. I used the cameras “backlight” auto exposure setting to obtain a bright exposure despite the strong sunlight. These shots were shot using S-Log3 in CineEI and it’s nice that the auto exposure functions work very well in this mode. The main lens used was a Sony 24-240mm f3.5-f6.3 zoom. Not the very greatest of lenses, but for such a zoom range the image quality is pretty decent. I used this lens because the temperature was often below -15c dipping to -34c at times. In addition there was a lot of blowing snow. I don’t like doing a lot of lens swapping in these conditions and the 24-240mm allowed me to take just one lens on most of the trips out and about on the snow scooters or dog sleds.
Another big help was the Core SWX V-Mount adapter. I used both the Core Neo 98Wh V-Mount batteries and some of my Pag Paglink 150Wh V-Mounts. They all worked very well in the harsh conditions and a great feature of the Core Neo’s is the run time indicator that gives an accurate time remaining readout based on the batteries capacity and the cameras power draw. This is very handy when using a V-Mount adapter as all the adapters currently on the market convert the battery voltage up to 19.5 volts to feed the FX9. As a result you don’t get any form of capacity or run time indication in the viewfinder. The Core V-Mount adapter also incorporates an LED indicator that turns red as the battery voltage gets low and then flashes red when it’s about to run out – a very nice touch. I did use a loose fitting insulated cover that I made myself. It’s not heated but does have a fleece lining so helps keep the heat generated by the camera when it’s operating in the camera. Where this really helps is to keep the lens warmer than the ambient air and this helps stop the lens from frosting over when shooting the aurora at night (see the picture at the top of the article where you can see just how frosty things can get at night).
As usual on these trips we had one guest break a tripod. A lot of materials that are normally solid and robust become very brittle at temperatures below -15c. I was using a Miller CX18 tripod head with Miller Solo legs and once again this proved to be a great combination. The fluid damping of the head remain almost completely constant all the way down to -34c. A lot of other heads become unusable at these sorts of temperatures.
For file backup and file management I use the Nexto DI NPS-10. This is a relatively new device from Nexto DI. Designed to offer a robust backup solution at a much lower price than similar previous Nexto DI products it too worked very well even in these harsh conditions. I have a 1TB SSD in mine and I can backup a 128GB XQD card in around 5 minutes. I can’t recommend the Nexto DI products enough for those that need to have a simple, reliable backup on location.
The workshop shots are part of a sequence of shots for another video I am working on. For these I used Sony 85mm f1.8 FE and 24mm f2 FE lenses. The sequence is mostly available light but I did have a Light & Motion Stella 5K on hand to add a little extra light here and there.
Post production was done using DaVinci Resolve and ACES.
