It looks like Pentax have already sold the 3 K3's

"First impressions review.."

Is it review or first impressions? Anyone else thinks its a bit stupid to name it like that?

On positive side, it was pretty fast.

"First Impressions Review" = glance at spec sheet, form impressions. Though if anyone actually has a K-3 in-hand it's gonna be dpreview.

Looks like $1297 Body Only in black, & they've got other options with various lenses including a couple plastic mounts & a silver body w/grip in Retro 1990's silver color all delivered "Nov 1st 2013":

Yeah, pretty weak but they will be adding to it little by little.

A better first impressions is probably here:

We'll have to see about how well SAFOX 11 performs, but if it's anywhere near on par with the D7100's system it should be a strong competitor

Don't bet on it.

That's pretty cool. I read elsewhere that it was a AA-filter in the firmware which lead me to think that it was just a software filter.

Most cameras have this feature as well. It's called mirror vibration Kidding aside it sounds pretty cool. I wonder how/if they're able to control the precision of vibration so that it's limited to the frequencies near nyquist, like how a well-designed traditional AA filter is expected to work.

That's what I'm also curious about.

Sounds like Pentax has gone with the Toshiba 24MP sensor, just like Nikon. I guess that's good news as it seems to perform better than the older Sony 24MP APS sensor as used on the NEX-7.

Well, Imaging-Resource has posted a really nice hands on article with a thorough geek lovers investigation into the new switchable Pentax LPF/AA filter technology:

"During the exposure, the anti-shake actuators oscillate the sensor assembly in either a circular or linear pattern, shifting back and forth a pixel or less in each direction. It thus does pretty much exactly what a conventional LPF system does, but without all the optical complexity -- and it can be turned on or off at will."

It seems amazing this can be controlled down to the pixel level.

Ah, so as I hoped, now just hope that accuracy will last.. dunno at least 3 years?

Otherwise, not so amazing. Ever heard of Hasselblad multishot backs? 50 mpix back which does pixel shifts and result is 200 mpix image.

Obviously if Pentax used brain a bit more, they could do the same.

Yes, the possibility that Pentax might do that was brought up prior to the K3 release over at Pentaxforums.

"Bottom line. It's not often that we label an imaging technology "revolutionary", but if ever one deserved to be called such, this is it. It's a fundamentally different approach to anti-aliasing, and one that appears to have surprisingly few downsides associated with it. For the first time ever, there's a camera on the market that lets the end-user decide when they want a low-pass filter, and when they don't, with little apparent penalty regardless of their choice. And it was Pentax that brought it to us."

Wow.

I have been looking for a new camera to shoot youth hockey games with. I have sold all my Canon gear and have been using the Fuji x cameras with some success for about a year now. But the Fuji-X cameras fall short in the Ice Hockey Action Department. This one looks interesting with a Pentax 60-250mm f/4 zoom. The pricing looks pretty good & the body has some features that one would find only on the "pro" cameras from other makers. I will be watching this one. especially to see how the AF works.

Expect AF-C to be on par with the E-M1 or worse and well behind the Sony A77 or the Nikon D7100. Pentax is simply not the brand you buy for shooting anything which requires fast AF (accuracy on the other hand is something Pentax has been good at of late).
