For the record, there is absolutely no rhyme or reason for the video you are about to see. It's purely random tests with the new Panasonic Lumix LX100 4K compact camera. Here's some very important notes about the video.

It was incredibly bright outdoors and the LX100 'NEEDS' an ND Filter. Unfortunately i'm traveling and the only one I could pick up was a very (very very) cheap 43mm Variable ND Filter. So if you see dark corners, or loss of sharpness, that's not the LX100. Yes i'm sure this really skews the results, but I seriously would not be able to have shot anything without one. I consider today to be just a big learning curve with the camera.

I tried shooting a variety of things, brick and roof tiles (testing aliasing), I shot people, I shot wide, I zoomed in, and I tested closeup macro. White balance was set to auto but you can tell it shifted quite a bit through the scenes. The extreme night shots were done at ISO 2000. This got pretty grainy, so you may want to keep things down under ISO 1600.

I was testing both manual and auto focus in video mode so you may see the camera hunt for focus at times. That could be me doing it manually, or sometimes it was the camera doing it. Focus peaking is available, but it's actually pretty subtle and sometimes didn't show up at all. Everything in this video was shot handheld - no tripods. I did at times use a PNC Pistol Grip, but that was it. The image stabilization on the lens worked pretty well despite my shaky hands.

4K Video Resolution
Here's another set of video clips [Uploaded in 4K resolution] I shot with the same cheap ND Filter the next day. I'm still using the Natural color profile with the settings turned down and adjusted the curves to bring up the shadows and push down the highlights. Make sure to watch it in full 4K resolution if you can.

Anyways, don't take the quality of these videos as a standard for the Panasonic LX100. The camera performs far better than what I was able to do in these random tests. It certainly takes some getting used to as there is no dedicated video mode. I also periodically ran into issues where I could not see how my aperture and shutter speed settings affected the image until 'after' I hit the record button. Basically you change your settings and think it's properly exposed until you hit record and then all of a sudden it goes dark. I believe there's some type of 'real-time preview' setting in the menu, which i'll have to dig for. Hopefully tomorrow i'll be a little more prepared and get better and more consistent video samples.

I was also amazed at the speed of wireless live view monitoring and controls with the Panasonic Image App. Maybe I haven't used it in a while, but it seems to be faster than with the GH4 when I first used it. Examining the video shot in 30p, I concluded that it was just 2 frames behind the camera's feed. The camera has 0 frame lag from what's actually happening 'live'.

I know there's a good amount of new DSLR shooters who haven't invested in ND filters yet, so here's a good example of the difference it can make to improve your DSLR video. To properly exposure on your DSLR you'll primarily be changing either Aperture or Shutter Speed. Since the majority of people love to shoot with a shallow depth of field (wide open aperture), changing the shutter speed is the only other option in bright days. This is where you could really compromise the video quality (unless you're going for that fast shutter look specifically). Get invested into some ND (neutral density) filters to cut down on the light so you can maintain that 'double framerate' rule.

To maintain the sharpest image possible, a single piece of ND glass is your best bet. The problem is that you need to have 1 filter for every sized lens, and you'll also need different densities according to the lighting. If you want to save time in swapping densities, you could get into Variable or Fader ND filters. These are adjustable filters that change densities as you rotate them giving you up to 9 stops in one single filter. Just be careful about the uber cheap ones. Here's a good article about those Variables http://cheesycam.com/variable-nd-filters-fader-filters/.

Here's a variable that i've been using with good results, but price has gone up a bit: http://cheesycam.com/nature-fader-nd-variable-neutral-density-filters/
