With F3.5 looks like truly expen$ive home movie camera. Most likely horrible motion effects and again- sound issues.

Aside from frame rate, will this provide the same video quality as the K-7? Just purchased a K-7 package, and am wondering if this would provide a viable option when 24P is called for.

Robert, dude, this is an interchangeable lense camera. Who cares what the kits is, when you are paying $650 for the package? Pentax has a vast array of excellent lenses and great backward compatibility.
Your home movie shooters wouldn't want 24P, and probably dont care about having an APS-sized sensor with reduced DoF either, but for a lot of independent film-makers .... that's EXACTLY what they want. |

Just bayonet the superb and knife-sharp SMC-M 24mm f/2 or FA SMC *85mm f/1.4 IF or SMC-A* 135mm F/1.8 or SMC-A 200mm f/2.8 or FA 300mm F2.8 IF or FA 600mm f/4 and see what happens... :)

Interesting thing is the sensor-based image stabilization - would be nice to use this combined with my old manual pentx lenses (assuming it works in video mode).
Unfortunately they went with MJPEG for the video codec though. No word on data rate but considering it's SD based I wouldn't expect it to be particularly high. Expect it'll fall apart with motion pretty easily.

QUOTE> will this provide the same video quality as the K_7?
The Kx has the same Prime-II imaging engine as the K7, but a different, non-Samsung CMOS sensor (12.4Mp vs. 14.6Mp in the K7). The Kx is capable of up to 720p24, vs. up to 1024p30 for the K7. Quality-wise, too soon to say but I would anticipate the K7 will be better. |

Owning the 5D2, the challenge is to stabilize the camera well, and use a filter if there is fine detail that will alias. If you take those two precautions, you can get great video. Also, the sound on the 5D2 is actually very, very good - if you use an external preamp, like a juicedLink, and run Magic Lantern to disable the auto gain. 6. Canon 5D Mark II Audio Exposed - Conclusions on Vimeo If you're shooting fine lace, handheld, on a boat in a windstorm with the built-in mic, yes, the HV40 will trounce any HDSLR. On the other hand, if you're shooting a romantic scene in a naturally lit restaurant, using a dolly, jib, steadicam, or tripod, the 5D2 (with good lenses, filters, preamp, and mic) will shred any small-chip camera. It's all about knowing the strengths and weaknesses of the tools and using them properly. It's also about knowing your vision and choosing the right tool for the job - and the budget.

Jon, Juicelink or other device- the signal still gets compressed- this is a real issue. I am working on a documentary, where some of the footage was shot with DVX100, some with HD100, some with EX1 and now some with HM100. You can't even compare compressed sound from DVX and sound recorded from EX1 or HM100 -uncompressed, even to untrained ear. Even low budget docs will have a separate sound person with 16 or 24 bit LPCM recorder.
Honestly- movie industry is not in a business of wasting money. If DSLR would produce adequate picture even for DVD release they would use it- trust me. Maybe the technology will get there in a year or two, but now it simply not there. So, no even this Pentax doesn't go beyond home use capabilities |

We recorded the audio of our recent 48-hour project into the camera, and it sounded great in the theater. Dream Job on Vimeo In fact, look closely at the video. You won't find rolling shutter problems. There's minimal aliasing. Aside from special effects shots, we only corrected five or so shots. The rest is untouched from the camera. No video camera in this price range could provide this result including the shallow DOF. (Red One? Yes. Film? Yes. But those cost well over five times as much.) HDSLRs offer budget filmmakers something that we could never afford before - shallow DOF with extremely low noise. And, yes, they are imperfect. But with skill, the imperfections are a non issue.

Jon, I should have checked Canon, but both Nikon and Panasonic have sound compression. As the matter of fact sound recorded (with a decent microphone) on Nikon was quite bad. I think it will be very hard to compare Canon 5D to K7. Canon 5D is a professional camera, costing 5 times more then Pentax or almost 2 times more then D90. So in a sense your argument doesn't contradict my statement- K7 will have most likely performance good enough for serious amateur use.

Yeah, there are DVSLRs and then there are DVSLRs.
The big difference between the top Canon cams and many of the lower priced entries is... * uncompressed audio * 1080p (many, including the K-x are 720) * high quality video encoding (h.264 at 40 to 48 mbps) * moderate rolling shutter (it's 25ms top to bottom on the 5D2) * price (though the 7D is "only" $1,700) Before long, DVSLRs will solve their aliasing problems and speed up the sensors to get rid of the jello. And video cameras will integrate large DVSLR sensors. The revolution isn't being televised, but you can follow it online. :) BTW, my sons are up in Bellingham (one at Western, the other at Whatcom). We shot The Murder of Dirk Snowglobe, a 15-minute short, up there with the 5D2. We submitted it to the Seattle International Film Festival, but didn't get in. (3,000 entries for 150 spots.) We're now reworking it, and will submit it to other festivals later this week. Soon, they plan to promote an on-campus showing of our previous films to help fund this crazy stuff. :)

I've laid into the 5D and 7D a lot. Although as a DSLR to take on holiday that I can also get adequate footage with I wouldn't mind one. But the aliasing alone, never mind the sound, puts it on the 'don't bother' list for me as far as professional work goes. |
