First Thoughts
Once in a while, a new product grabs our attention during review. Unfortunately, that is much less often than you might expect. Technology breakthroughs are truly rare, and most of what we see in the technology arena is evolutionary. Technology is also fast moving, so innovation by one player normally finds its way - quickly - to other new products.
It is far too early to draw conclusions about the new Pentax K20D, but we do confess that most of our questions about this new digital SLR have had positive answers. The new 14.6 MP Samsung/Pentax sensor is for real. Noise is admirably low and the CMOS architecture assures extremely low power draw and long battery life.
In early testing there was no substantive difference in image quality from ISO 100 to ISO 1600, which is a noteworthy performance for a sensor with a 14.6 MP resolution. Images were also very usable at ISO3200, even when enlarged. ISO 6400 was not as useful, though small prints and web publishing should be fine with the 6400 setting. Our fear was that Pentax/Samsung had given up the store to have the bragging rights for the highest resolution DSLR in their class, but that is certainly not the case. The image quality was at least as good as a Sony A700, but we have not yet compared results to the Nikon D300.
Pentax K20D features seem to go on and on. In fact it is easy to get lost in all of the extensive image control that is possible with this new camera. Fortunately, Pentax keeps everything under control with their Info button and the most common controls - White Balance, Drive, Flash parameters and ISO - are easily accessed with the Fn (Function) button.
The in-camera image stabilization and sensor cleaning have been improved over the K10D, according to Pentax. We haven't yet tested this claim, but hand-held low light performance was impressive, and dust on the sensor has not been an issue so far. The dust mapping strikes us as a bit gimmicky, but those who work in dusty environments will probably disagree. We weren't anxious, in early testing, to expose the sensor to a lot of dust to test its usefulness.
The new motor lenses are something of a revelation. Our 16-50mm f2.8 was completely silent and very fast. Compared to the record-setting speed of the Canon 40D and Olympus E-3, the motor lens performance gave up nothing to the Ultrasonic or SWM motors. Non-motor lenses were reasonably fast, but no real competition for the best from others. They were also a great deal noisier as we have seen on screw-drive AF lenses from Sony and others. Pentax needs to introduce more SDM lenses as soon as possible. Once you use one it is hard to go back to screw-drive AF even on a good lens like the 50mm f1.4.
Overall, we found the K20D exciting in early testing. The combination of a 14.6 MP low-noise CMOS sensor; a dust/splash-sealed body, grip, and lenses; and the new SDM motor lenses is very satisfying. This is not the camera for sports shooters, as the 3FPS shooting speed will be laughable to action shooters. However, the incredible feature set, useful and unique program modes, and solid construction and performance will likely be well-received by the rest of the photo world. Our full review should provide even more answers to our questions about the K20D. If you have any specific question, chime in on the comments and we'll do our best to address those as well.

The HypP mode is different from the program shift that you can find on other manufacturer's models.In HypP mode, when you select an aperture, you're effectively going to Av mode, meaning that the camera will keep the selected value for all subsequent shots and adapt the shutter speed.
Same goes for selecting a shutter speed that gets you in Tv mode.
Each time, the selected parameter is underlined in the VF so that you always know which parameter is dominant.
If at some point you decide you want to hand control back to the camera (ie switch back to P mode), you just have to press the green button.
Simple, usefull and very efficient.

I appreciate that, but what you've both described is what happens in A & S Priority for Nikon (*screams*).In A priority, you select an aperture, and the camera picks the shutter speed. The aperture does not change until you change it (ewven if you turn the camera off. You know Aperture is dominant because you've turned a dial to set 'A' for aperture priority.
Vice versa for shutter priority.
All HyP appears to do is allow you to go directly into A or S (and effectively full manual if you do both), without turning a dial.
You do however need to press a button to go back to full P. So it saves you that initial click. But it does sound pretty handy, and easy to use.
Unless I'm missing something blindingly obvious, in which case I sincerely apologise for wasting your time :o

Yes, the only thing the HyP mode allows you to do is switch between P, Tv or Av without having to stop shooting to switch some dial.It may look like a small subtlety but I can assure you it just makes the photographer's life easier.
It's instantaneous and the camera just doesn't get in your way when faced with changing conditions and that's what's interesting about it.
I use both Pentax and Canon systems and still cannot understand why Pentax are the only one to implement such things as HyP (or even better: HyM mode) or to allow the user to set the ISO directly with some dial and use one button press to go to auto ISO.... these are just things that make you forget about the camera while shooting and being able to control everything without ever leaving the VF from the eye.
The 'philosophy" is rather simple IMO: give the photographer a way to adjust any shooting parameter (shutter speed, aperture or ISO) when he wants it and without having to bother about pressing a dedicated button or changing a mode dial.

I suspect that Pentax aren't the only ones to give that functionality but probably are the only ones to do so in that exact way.Minolta (now Sony of course) were always thought of as cameras designed by photographers for photographers (Canon are designed by engineers for marketing :P) - I suspect that theirs & Pentax design ethos are very similar.

Pentax & Minolta/Sony (& probably others) have full A & S priority modes as well though.Going by a later, fuller description of HyperProgramme it does seem to have slightly more than Minolta/Sony's implementation although I would argue that at least some of that secondary ability is covered by user ability/knowledge (I assume that most users of that level of camera have some experience & appreciation of the effects of aperture & shutter) as I'm sure that you would with Nikon.
On my A700 I have Auto, Programme (3 versions), assorted scenes modes (which I suspect also largely covers the secondary abilities of Hyperprogramme), aperture priority, shutter priority, 3 memory settings & of course full manual - a bit of overkill imo.
It's not surprising that I see more people eschewing automation & going back to doing more manually.

The K20D also has Sv (sensitivity), Tv (shutter), and Av (Aperture) Prioriy programs. Theres is also a very interesting and unique Mode called the TAv (time & aperture priority). In TAv mode shutter speed (time) and aperture are fixed and only the ISO is automatically adjusted for the proper exposure. The camera adjusted ISO is displayed in the viewfinder and blinks if the exposure is out of range. Shutter can be adjusted with the front dial and aperture with the rear dial.There are some situations where you might require a certain aperture for depth of field and at least a certain shutter speed to prevent blur and that is where the TAv mode could be very useful. As far as I know the K20D and K10D are the only SLR cameras with anything like the TAv Program.

Minolta/Sony seems very similar - you actually have 3 Programme modes (as well as full Auto) incl. Pa & Ps where the camera will remember the adjusted setting for future shots & vary the other to compensate as the lighting changes.Wesley Fink - Tuesday, March 11, 2008 - link
Most manufacturers do have variants of the hyperprogram feature and I've used almost all of them. However this Pentax feature is still one of the easiest to use and most flexible when you add the unique Sensitivity Priority program.dug777 - Tuesday, March 11, 2008 - link
Regarding my description of the Nikon D80 system, how exactly is it easier?As far as I can see it's effectively identical (and incredibly easy to use).

See lol101's description of Hyperprogram below or my detailed desription on page 2 for more info on the specifics of how Pentax Hyperprogram works.
