In Topic: Olympus GoPro killer?

It only supports NTSC frame rates (ie multiples of 30p), there's no info on the amount of compression or expected but rate, and there's only a handful of white balance options.

I didn't get as far as reading about the automatic underwater function, but if that automatically flicks on the underwater white balance when you get underwater then it'll really ruin your day when you switch on your lights.

As interceptor says, you're not comparing like for like. HD100 uses interframe compression whereas HD200 uses intraframe compression. Both are variable bit rate, so the actual end bit rate returned will depend on the subject and the type of compression applied. A low lit area with lots of dead space and no movement isn't really going to put the compression to the test.

Shift your test to a well lit subject with no dead space and lots of movement, you'll see something difference.

In terms of your test, your pixel peeking on a single image, so not really a conclusive or comprehensive test when comparing the quality of a moving image across different compression methods and resolutions ;)

Ah, missed the limit on the wide angle on the adapter

Again, personal choice, but I wouldn't be too bothered by trying to retro fit a back filter if it means using tape etc... Too much potential for gunk near the sensor and owns workings for my liking.

Another option would be to fit a filter step up ring to the outside of the lens hood, then fit a filter to that. Provided that the adapter ring ding sit proud of the lens hood, you wouldn't get any vignette etc, although you would need to ensure the step up ring fitted inside the done port aperture.

I wrote to Alex and he replied that he is not sure none of his rear lens filters would fit in the  Pana 7-14mm. Let's see if someone comes up with a solution...

 

 

How about this?
