A pair of used Panasonic GH2s using old Pentax M primes plus a pair of CFL soft boxes and you'd have a killer HD setup for less than a grand. If you wanted 4k/60FPS though you'd have to step up to the GH4
Thanks. The noise is caused in part by the sensor, and in other part by low bitrate. Adding a GH2 may be a good option. Looks like they are not too expensive.
I read that the GH2 still has the 30 min limit however- though there are hacks to remove it, but apparently not in 1080i (30fps) mode.
Somebody else in the "non-Pentax" forum also mentioned the GF2 which is even cheaper and has hacks for higher bitrate/continuous recording as well. The proper K-mount -> m4/3 adapter with aperture ring costs about as much as that camera...

Right. The GH4 does 1080/60fps or 4k/30fps. Maybe the GH5 will do 4k/60fps . No announcement yet.

Apples and oranges.
The sensor size is much smaller. I couldn't find the specs on what it is exactly in the WG-M2 .
Assuming it's the same as WG-M1, it is 1/2.3" which is 6.17 x 4.55 mm or 28 sq mm.
Full frame is 36 x 24 or 864 sq mm.
Ie. the K-1 sensor area is 30.8 times as large than the WG-M2 sensor.
FYI, I actually tried a Sony FDR-AX33 camcorder that had a 1/2.3" sensor and found the video picture much too noisy indoors. I ended up returning it.
The WG-M2 has a fixed ultra wide angle lens, also, which is not what I want to use.
I do like that the WG-M2 has continuous recording and 100 Mbps, though.

Originally posted by bxf So I'd like to know what are the minimum video specs that would be satisfactory to those who consider video performance important?

I can only speak for myself also.
- In terms of quality, yes, IMO, the current specs are really inadequate. My 2008 vintage Canon HG21 camcorder can record 1080i in H.264 at 24 Mbps.
My Pentax K-30 can record 1080i in H.264 at 22 Mbps.
It looks like the K-1 will be the same H.264 22 Mbps bit rate as the K-30 .
It makes no sense that the bit rate is so low while the sensor size is so much bigger, and optics also potentially much better depending on the lens used.
- 4GB recording limit makes no sense in 2016 . The 4GB limit means 16 min max recording limit time on my K-30. That is too short.
- Most 2016 vintage cameras >$1500 can do 1080 at 60fps , not 30fps . And many much cheaper than that can too. My cell phone can do 1080/60fps, for 10 minutes.
- many cameras can to 4k at 30fps nowadays. Even my cell phone camera can, for 5 minutes.
