Windows colour management... well, is like a pain

The calibration is loaded at the start to get the monitor basically right for all non-colour managed applications. It won't necessarily be sRGB (unless you calibrated your monitor to the sRGB spec), but at least when the software asks for specific percentages of red, green, and blue that's what you'll get.

On the other hand, when you have colour managed software it will use a colour transformation to accurately display, or represent, the gamut. For example, your monitor may actually be somewhere between sRGB and AdobeRGB (sRGB is very limited in scope, and AdobeRGB is wider still). Only when the application is colour managed will it perform the transformation from the image colour space into the monitor colour space.

As a case in point, I have a tablet PC which monitor profile causes all kinds of oddities when you don't use colour management.

With Apple, the colour management is built into the operating system... and not bolted on

Might not be clearer, but hope it helps

There's almost a way of working round it - I can put the AF540 on one of the cheap optical triggers and use a pre-A lens (or an A lens in manual), because then the K10D does not emit a pre-flash.
You need nothing for the AF540 Set the mode on the flash to "SLAVE 2" and it will trigger off dumb flashes... even Canon ones

You just need a simple trigger on the body... like an AF160 or similar "stupid" flash.

I agree it would be nicer to allow for studio triggering out of the box. But it's definitely not a show-stopper... at least not in my book

There are lots of subtle improvements over the K10D: battery life, dynamic range, 14.6MP but two things stand out:
38 JPGs burst
230,000 pixel screen!
Subtle those changes are not!
38JPG burst - that was at 3fps (because of the larger sensor size). Apparently you can notch it down to 2.7fps and fill up your card.

I suspect the LCD is down to having a wider angle screen - 160 degree viewing (for the LiveView). Doesn't bother me in the slightest about the size or number of pixels.

...mount a small manual gun
Like the AF160 which will cost you all of, say, £9
Or, get an IR transmitter that sits on the hotshoe... that'll trigger most Elinchroms etc. That'll set you back around £30.

No problem

I'm seriously excited....

Quote:
Focus error correction, calibratable monitor, freely selectable file names
Other highlights of note:
* Multiple exposure - 3 or 5 shots (great for HDR)
* Dynamic Range Enhancement
* Preview image can be saved
* Same mode dial & wheel operations
* Live view can zoom in (as far as I understand it)
* Ability to detect where the dust is on the sensor


Anyone want a K10D??

I may stand corrected
A BabelFish quote from the K20D brochure:
Quote:
with the LIGHT the SCHrITT holds: pENTAX prImE processor. In order to let pictures of high eindringlichkeit develop, it needs a camera of highest quality. So the basic idea with the development of the processorprocessor processor for the K20D. The engine supplies the necessary computing power to process in order to manipulate and store colors nuanciert too beeinfl ussen, RAW data comfortably preview pictures purposefully, the volume range from photos to to improve and much more besides. Auss­erdem permits the PRIME to series exposure of approximately 3 pictures per second, in the BurstModus even up to 20. Thus the K20D is very fast, if also not the fastest one in the market. Because as said: For the PENTAX developer had the task of priority, how one realized photos of special quality. Not the question, as one fast particularly makes many photos.
"BurstModus" up to 20

Dynamic Range extension, uses same grip as K10D... ISO100-6400

I'm trying to find something I don't like

Does that mean 20 frames per second?!!
20 screen updates per second - re Live View I presume

Note: the K20D uses the same grip and battery as the K10D.
It takes far less power because the K20D uses a CMOS sensor, and the K10D uses a CCD sensor

Ben,
A few serious questions:
1 ) Does it use the same grip as the K10D? (would be useful!)
2 ) Is plain TTL supported?
3 ) Is it still the "crippled mount" (ie doesn't pick up aperture ring of older lenses)
4 ) Any news on who will support the RAW format first? (Hopefully Silkypix as with K10D!)
5 ) Are there options for HDR-style capture (ie 3 or 5 frames, 2Ev apart)
6 ) Will wireless flash be supported as with K10D? (Will they add HS too?)
7 ) How quickly can you set up a manual white balance? (I'd prefer button access)
8 ) Please, please, please tell me they support Sv and the ISO-on-wheel settings of the K10D! (Can't live without that!!)

Oh, yes, and when and how much?
Matt

Yes, you set focal length x 1.7 into SR.
The aperture change is effectively 1.7x as well (according to the book). However, that gets a bit silly when representing the aperture on the camera, so it appears that it will just use a close match... it may even limit to f/2.8. However, everything will even out with the metering.

Just enjoy
Matt
