Filming a weaver in Ayacucho
I have had the Sony FS100 for three weeks now and have used it on three interview shoots and about 10 minutes of b-roll. Here are are few thoughts about the camera based on that experience:
1. The camera is perfect for interviews – For years I have struggled to get shallow depth of field on my interviews. In the early years Hasina, Rado and I used to move the camera back from the subject, open the aperture as wide as possible and zoom into the subject to get the background out of focus. Of course if you ended up in a small room or any other place with limited space your options were limited. When the Letus extreme came out I bought one for my HVX200 and eventually used with with the Sony EX1. I bought the fast and sharp Zeiss ZF 50mm and 85mm lenses to use with the Letus. This worked great, however, the Letus was yet another thing to carry around and it took about 10-15 minutes to set up. In addition, there was about 2 stops of light lost to the devise and if you weren’t careful you would get an ugly smear across your frame from the ground glass. Despite these limitation, I have shot close to 100 interviews with the Letus and it has served me extremely well.
Next came the 5D, which I have used on a couple of interviews, but I was always a bit put off by the fact that I had to do double system sound, so I actually stuck with my Letus and the EX1 for many interviews even after I had bought the 5D. In addition to the double system sound I did not like the compromise between either choosing and image with artificial sharpening or soft edges on the 5D.
The FS100 solves the problems associated with both the Letus and the 5D. The lens is mounted directly onto the camera body, so there isn’t any light loss or ground glass to deal with. Using my Zeiss lenses, the images have a shallow depth of field, but what is in focus is super sharp without too much artificial sharpening (I know ever digital image is sharpened to a point by the camera, but the FS100 has been well calibrated). The camera also features two XLR inputs, so I don’t have to deal with double system sound.
So, overall I have been extremely happy with the FS100 as an interview camera.
2. To all you digital filmmakers out there…better get to know what a matte box does and a study your filters – The FS100 does not have any built in ND filters, so the only way you can use it outside in bright daylight is to close the aperture beyond F8 and crank up the shutter speed. Both of these things can damage you image quality or create an unintended look, so the preferred solution would be to put a matte box in front of your lens with some 4″x4″ filter of choice. ND6, ND9, polarizer, ND grad…there are a number of filters that would work really well with the camera. I am just beginning to process of exploring the use of matte boxes with the camera (or any camera), so I ill keep you posted as I learn more.
It is clear however, that adding a matte box will weight the camera down and make it more difficult to shoot handheld. Again, I will be testing out different handheld setups and discuss my thought in the blog.
3. It is possible to shoot handheld – The large sensor of the 5D is a jello magnet and it is almost impossible to use an un-stabilized lens on the 5D without getting a wobble in your frame. When I first put my 50 mm Zeiss on the FS100 and tried to shoot handheld the image was definitely not stable enough to include in a video I was shooting for a client. However, after some practice bracing the camera against my body I was able to get images that were fairly stable (see video). I have recently purchased a Nikkor 35mm F2.0 to use on the camera and the wider angle significantly reduces the amount of jitter in the frame. I am also in the process of building a DIY rig to use with the camera which I will demonstrate in a later post.
Final verdict – It is possible with the FS100 with manual lenses, but you have to be steady and use a support system (Even though it is more forgiving than the 5D). For tracking shots you need to use a stabilizer like the Glidecam or a Steadicam rig.
4. Final thoughts – There are a few other thoughts I wanted to add that don’t fit in any particular category:
* The camera’s peaking feature is exactly what we all wish we could port from the EX1 to the 5D. It is so easy to use!
* The peaking function is visible in the expanded focus mode, so you can benefit from peaking when checking your critical focus.
* The expanded focus mode doesn’t time out. This is nice because you can take your time checking focus.
* The FS100 files expand in size when they are converted by FCP7 using the log and transfer function. I just noticed this and have not tested out what affects the size of the file, but they definitely become substantially larger (more on this in a later post).
