So they must use line skipping, pixel skipping or extensive image scaling to get down to video resolutions. This has a negative effect on the image quality and can create image artefacts that use a lot of encoder bandwidth. Also the encoders are not as well optimised as the dedicated video encoders found in most video cameras. Not sure I'd want any form of automatic tonal adjustment, that would take your control over the image and exposure away. The video camera sensors are normally protected behind an optical port, so dust on the sensor should not be an issue. DSLR’s use sensors optimised for high resolution stills.

The Fibertecs are very tough. A wipe down with a damp cloth helps keep grit out of the channels. I've always kept my legs locked even when not in use. After 10 years they have only needed adjusting a couple of times. There is an allen head adjuster on each locking mechanism. The Fibertecs proved too costly to make at a competitive price which is why they were only made for a short period. I do try to look after my gear, but sometimes things do get bashed about.

Sometimes you can go too fast though. The rental of a Flex for a week would be 1/3rd of the cost of buying an FS700. Perhaps. Sometimes you can go too fast though.

You need exceptional low light performance. I would suggest you use a DSLR with a 4 or 5 second exposure and shoot time-lapse. There is no low cost camcorder that I can recommend for this.

The solution is to use a 1/50th shutter. Yes, it’s because you are shooting at 30fps in a country where the mains frequency is 60hz. The solution is to use a 1/50th shutter.
