Here is the announcement http://www.pentax.jp/english/news/announce/20101029.html

They somehow increased the number off frames in Continuous Hi burst from 8 to 20 PEF raw frames at ISO 100.
Lets hope that's true


They also updated the PEF codec for Windows and Mac.
They improved/updated;
- Support for the K-r and K-5 camera.
- Added [Bleach Bypass] mode on Custom Image function.
- Add [auto correction] on lens correction item
- Added lens data.
[smc PENTAX-DA 18-135mmF3.5-5.6ED AL[IF]DC WR]
[smc PENTAX-DA 35mmF2.4AL]
- Improved response of general performance.

Here is the codec, still not for 64bit though.
Windows
Mac


For the 645D there is some hinting for tethered shooting program.
Here is a babblefish translation.
"A remote-access application will soon to be added to this software,
allowing you to control your PC from a distance using the 645D."

I doubt you can control your PC with the 645D so lets assume it's the other way around for now


oh and if you want you can send your Km, Kx and/or Kr to Japan for a different grip colour

I am staggered - 20 frames per second!

We really are talking about a market leading camera now; we already have the highest ISO setting available on APS-C; and now the fastest 'genuine' fps, provided you shoot at ISO 100.

I'm really impressed with what Pentax are pulling out of their sleeves; and I'm starting to undertand why they think they can pull in such an increase to their market share over the next few years.

Canon and Nikon cannot compete with the K-5 at the moment that's for sure.

I'm curious how they're able to increase it so much though... maybe they have lower the compression so the CPU has less to do?
I doubt they have unlocked more RAM somehow because it would be silly they didn't do that from the start.

That's exactly how I assumed it also - the Camera CPU has less processing to do.

Though I imagine there will be a caviet with regards to the type of memory card you have.

There might also be some optimization involved most likely because they also improve the performance of the Codec for Win/mac but but no way optimization alone can account for 150% increase

I've remove that comment that they maybe use the SD-card as an buffer for that reason, you're talking about an unprocessed format straight from the sensor... what would that be 40MB or something like that if not more?
If so no way a SD-card can be used to increase the buffer

Lets do some calculations.

the image size of the K5 is 4928 x 3264 pixels so 16.084.992 pixels in total and those are 14bit deep so that is 225.189.888 bits = 214,757812 Mb (megabits) = 26,8447265 MB (megabytes)

And that x7 times each second (7fps) = 1503,30468 megabits or 187,913085 megabytes each second for the processor to handle

What does the fastest SD cards do?
The new SanDisk introduces Extreme III do 30MB/s no where near the throughput needed off 188MB/s
Add best a SD card buffer would extend the total images in the buffer with 1 but it would be unable to receive images that the processor has finished...
So the gain might even be a negative number


just to show the difference.
The K7 has 20,7451172 megabytes photos and it can "only" do 5.2fps so that's 108MB/s

It's not 20 frames per second, it's 20 PEF pictures in continuous HI shooting.

Er....no!

Would be nice, of course but this update increase the buffer to 20 shots instead of 8, not increases the fps from 7 to 20!

I wonder if the update is processor base because they use the same processor in the K7 as in the K5 right so they should also be able to do it with the k7 maybe... i wonder what numbers you would get then.
Maybe the processor can keep up with 108MB/s meaning your SD-card would be the weakest link.
It's either to slow or it would run out off space... or the sensor over heats?

As it was mentioned on the 'other forum' manufacturers often design in some wriggle room and it's likely there were already the solder pads for extra memory on the camera's motherboard. If this is the case it's possible Pentax added another memory chip after receiving early beta testing complains that the buffer filled up too quickly. This memory would possibly need a firmware update to recognise it.

That scenario seems highly plausible to me.

Sounds strange too me... why spend the extra money to have the extra memory or other things there and not use it?

Sure there might be room to upgrade it just like you've room for 4 RAM memory stick in your computer and only use 2 sticks.
But it's strange to buy 4 sticks and put them on the motherboard and than disabling 2...
I'm very sorry but I can't see the logic in that

Why not? It makes perfect sense to add solder pads for future upgrades. the motheboard could be used for a K-5b or something.

Because the pads are ready on the motherboard all they have to do as add the extra memory chip to the production line and release some firmware to access it.

and the speculation is that they had early complaints about the tiny memory size they probably decided to add the extra chip(s) before the release date and then test and release the firmware to access it.

It only a theory, but the extra memory wouldn't have been put in the camera in the first place and not used as that doesn't make commercial sense.
