I'm trying to imagine a situation in which I'd be shooting in high-speed burst mode in dim lighting—failing to come up with anything.
Well for sports offcourse as a main issue. I did some volleybal international game between The Netherlands and Cuba 2 weeks ago (at the time they are in Japan for the World Cup) in what is in The Netherlands the best indoor sportsarena as it comes to light. All other venues have less light, so I would like to use the K-5 at burst mode and high iso (iso 2500).





And many other shots from that game.

What the …
How can this be?
Did they reduce the image to 12bit?

I hope someone who knows more can chime-in on this !
Has anyone tried it?

If this is truly the case, then I'm done with the D700(I can finally sell it)
No any problems. The same firmware was for Sony A100. They can change the algorithm of writing files. Even without 12-bit.

The Nikon D7000 does 15 Images compressed NEF in 12bit and 12 Images compressed NEF in 14Bit This all @ 6fps
Nikon D7000 has 10 NEF in 14-bit mode without compression

It seems to be even less than that based on what users have written on DPReview forums.

Hello, Have two 16g Sandisk extreme class 10 / 30m/s cards for my d7000. Using a customize sport setting the picture buffer shows 8 available and set the shooting mode to CH. Holding the shutter down, the camera ran through over 30 shots and the picture buffer never dropped below 5. I shot XC and track so speed is important and these cards are great.

After the new firmware arrives, it would be handy to see a table similar to this (from the D7000 manual) in the K-5 manual or elsewhere:


At the moment the K-5 manual description (p151-152) of continuous shooting is a bit thin on that sort of detail.

didn't time it exactly but it seems to shoot at or close to 6 fps at 14 bit RAW on CH mode, but unlike the '100 jpgs in a row' state by manufacturer, even with a class 10 SD card in place, it seems to pause after 8 or 9 shots to give time for the memory buffer to clear out before it resumes rapid burst shooting again. Makes sense to me. Each 14 bit RAW file is about 20 MB give or take...

Boy if that is what Nikon is doing I'm surprised even back to the days of CP/M (no smirking) you could "clear" (delete) a file by writing one byte to the file table (was is called the FAT table in CP/M?).

You don't have to clear the buffer memory just set a "dirty" bit.

Ahhhh, unless by clearing out buffer memory they really mean a complete write to the SD card.

By "clear" I think it's safe to assume "write to disk so you can overwrite"

"Write" you are. Still working on my first cup of coffee.

Were you CP/M programmer ?

I toyed around with no-brand Z80 machine in my student days....it was already obsolete at the time, but interesting to tinker with.

Dear Lord here we go. Yes, C and assembly, CP/M, DR-DOS, MSDOS,WINxx, LINUX, embedded RTOSes. Too much on my CV I'm not even mentioning things anymore.

Falk Lumo has written an interesting take on this
https://www.pentaxforums.com/forums/pentax-news-rumors/120228-announced-firmw...ate-k-5-a.html

I would still want the 14 Bit RAW for the highest quality still shots, but a selectable 12 Bits would be a very acceptable trade-off to get 22 frames buffer.

Well, the Pentax reps at Photokina (and the printed brochure) did mention the final RAW buffer would be higher than the 8 frames, but today's announcement is the first official commitment from Pentax.
Well all that is stated is just pure conjecture and I wouldn't give too much credence until someone can actually prove it is the case. Too much hypothetical pseudo science imo.

Ah, the good old Z80! In my day we only did minimal basic programming with the Z80, then we moved to the PIC1684 for the rest.
