Yana36 (or whatever he/shes called) claimed 5 fps at 6mp. Ogl I think has claimed the same as Yana (is this a surprise? hmm....)

I would be fine with 5fps at 10Mp but 5fps at 6mp is weak. It looks like the mirror box won't get upgraded from the K20D then if this is the case. The data through put must be fast enough to handle 10mp at 5fps at least. Remember that the K10D was equipped with DDR Ram capable of reading (and writing?) at 800 mb/sec - clearly the bottle neck is not here assuming the K-7 has the same speed memory or faster.

Are we talking fps with LV or in "normal" mode?


High fps without AF, even at a decent resolution (6MP is OK by me) is pretty useless IMO...

Why without AF since there's contrast-AF ?

I don't know but I would assume its mirror up and reading the data off the sensor. No AF then unless Pentax has worked really hard on contrast detect AF

you're right people often confuse file formats with codecs or compression

file types i.e. AVI,QT,MOV are file wrappers that a particulat operating system like to work with. we ofter refer to these as wrappers

the actual visual informationis encoded using codecs

think of file types like a book you can have hard back or softback or tradeback even electronic

each book can hold the same information or story. you can buy the da Vinchi code in all of the formats the story is eaxctly the same.


think of codecs as languages like english, german,spanish,galelic etc.

you can have the same story in almost any or these languages . so you can have a paper back in German and in English of the Da Vinci Code or you can have both in hardback.

content, codec/compression and file types are all three different iand separate pieces of the same puzzle for processing video.

each codec has its strengths and weakness. the current crop of mpeg4 four based codecs are extremely efficient in compression and maintain high quality. h.264. WMV, divyx, bluRay, AVCHD and the new versions of QT are all derived from mpeg 4 technology and share common technology

mpeg 4 and mpeg 2 (common in DVD and digital cable) share common traits for compression but mpeg4 is more advanced in it's intra frame compression with is use of layers helping it achive much tighter compression with a higher quality. mpeg4 is general regarded as able to achieve comparable quality to older compression schemes at half the bit rates.


QT or Mov file formats are preferred by many manufacturers due to a higher compatibility. Most windows machines have a version of QT installed on them so a .mov file will play. on the other hand try to have a mac guy install the current avi/wmv drivers on his mac is like asking him to sell his children in to white slavery(IMHO).

QT and AVI both support hundreds of codecs and none have native codec so to speak. The codec of any of these files are pretty much voodoo to most users who only see the file extension and assume that that is all there is too it.

currently the industry is moving to a philosophy of dividing codecs into three families. acquisition, intermediate or editing and distribution

acquisition codecs - feature high quality and small sizes - the mpeg format codecs are very small but feature inter frame compression where multiple frame are used to "re"-create a single frame this is great for space but create problems when editing

intermediate or editing codecs - feature high quality but but a a cost to saving space. storage of a high quality and easy to edit file can use ten time the storage space of a acquisition codec. fortunately most editing software will soon allow native editing of acquisition codecs but a more powerful computer will be necessary to "re"create each frame as it is being edited

distribution and delivery codecs vary greatly since content is now streamed to cel phones as well as broadcast on TV . and each delivery codec is tailored to the needs of the delivery method


just my $.02

As others have said, you confuse a program (QT) with a media format.

MP4 / AVC aka H.264 (.mp4) is the current standard HD video format, as broadcast, as played by most current media boxes (or PS3 ), BluRay, etc. pp.

It is also providing the best image quality at a given bitrate.

That Apple pioneered to support this format in their QT software doesn't make it less valuable. To the contrary.

When Pentax made the K20D, Pentax wasn't able to make a smaller camera with seals so my statement was absolutely correct.

According to my inside info the K10/20 were made to a size with no attempts at miniaturization. Pretty much the way Canon do things (for their larger bodies); they decide the size first, then build it. If you look at some of the circuitry boards of the K10D you'll see it is pretty much like a card for your computer! Nothing much have happen in miniaturization of circuitry boards the last few years.

Yes, weather sealing occupies space; a few millimetres that is.....They can make any lens weather sealed if they want to at no great expense.....

[janneman]

If the Limiteds are getting seals, this means optics and mechanics must shrink. New thinner materials for the outer casing and new optics to make a smaller and more compact lens. All this cost quite much money, and I have my doubts about Pentax preparing to invest in luxury extra thin materials and extra small optics with top performance just to get seals to the Limiteds, and I have my doubts about the user preparing to spend the extra money needed for this luxury research and development.

I am not sure why the optics have to become smaller... They are so great that I will settle for a D FA31/1.8 LE WR that has the same optics, just a housing that is sealed which would mean a few mm's thicker... The 31 is already big, thise additional 1-2 maybe 3 mm won't matter too much.

This thread just passed 200k views Should be a new PF record

[vizjerei]

sigh... so need to get new batteries also well...

[dopeytree]

Do we have an exact release date or even an order date? I need to sell my K10D with grip, 3 batteries, 2 chargers and kit lens and keep the rest.
but I can't be with out a camera for too long! How do I tell how many shots it fired on a mac?

[Kunzite]

1. The body is made very good.
As is the K20D
Non-standart for Pentax.
They moved the buttons randomly
2. Design is very special
Yes, see above
3. No specs at all
They misunderstand something. It should be "speechless", not "specless"
4. VIDEO
Can I use it as a webcam?
5. Support Both Body Driven "Screw-Type" AF KAF and SDM KAF2/KAF3 Lenses
I was afraid that many current lenses (including Limiteds) will be obsoleted. Not.
6. SD/SDHC
No SDXC? Bummer.
7. New battery
More accurate charge level indicator? Who knows...
8. New battery-grip
9. New WR kit lens
I would prefer a WRC kit lens, instead
10. AF assist lamp
Voila! AF issues on low light solved!
11. Rear LCD 3.0"
Bummer. Probably, one of the reasons they had to move the buttons all over the place.
12. LV
You mean, improved LV?
13. 77 zone of light metering
The more, the merrier. At least that's what Nikon thinks.

It's all. No any additional info.
Good. Any information has the potential to kill speculations.

5 fps at 6MP? How many at full resolution, then? More than the K-m, I'd say.
Which means, (at least) 4-4.5fps at full resolution and 5 at 6MP. Something doesn't make sense

Why without AF since there's contrast-AF ?

I have yet to see a contrast AF system able to follow a moving target at 5fps on a DSLR but maybe the K7 will be the first...

[Gimbal]

hm, doesn't look that "limited" to me, more like it's made of rubber..?

[torge]

could that be a lever for DOF preview on the right side of the mount (left in the pic)? Would be close to the same spot as used on all the classic, although actuation would be more likely a push towards the body instead of the mount as on those old models. That would free up the lever around the shutter to do what?

In film days I used DOF preview all the time with my MX and LX and found it very usefull. Since APS-C I have hardly used it, as it just doesn't seem to work. This has always been my biggest grief with the smaller format, not so much the quality or iso performance.

I hope they have done something to the viewfinder to bring it closer to the old film days quality!

Cheers,
Torge

Looks like it got a DA* 55mm SDM with the hood, definitely not the new kit lens anyway in this photo.
