I will tell you one thing I will never bring any of my camera's to GB.
In fact I think I will just stay on the Continent were I can photograph.

The question is Live view.

If we are going to use live view then the nose is not an issue here.
I would not use the view then correct?
But like I said before adding a infrared sensor either by the eye view or when I put my left hand back on the camera again the touch screen is disabled.
Mobile phone like the Iphone are only touch screen and I do not know of anyone having a problem making a phone call and dialing the wrong number.

As for using your left eye in the viewer, I have been using cameras for over 20 + year with my left eye with never a problem. What type of problems does your husband run into in regards to using his left eye?

But getting back to the K20 replacement.

I think some of the idea's I have put here are good. I am not saying all are or would ever be added to a new K model. But this is room for Improvements to be made. I understand the Oppositions to a touch screen. But I see somewhere down the line these type of changes to the SLR camera coming. More use of the screen as a fuctional tools. Rather than just sitting there blank most of the time.

"You don't work in InBev Quality Control do you??"

If I did would that make it better??

No I work in the Antwerp Harbor and love to drive E19 and the ring.....

What I am saying is that the camera is in full touch screen mode at all times. Then when I put my left hand on the camera then the screen stops to function. It will only work when my left hand touches the screen. So there is no change of settings changing.

Another thought.
No battery grip a complete unit.
Then you can make the screen even bigger.
The Camera can be charged with out taking out the battery or batteries.
Plus run on electric when you want to.
A hard drive with 40GB built in.
You get everything when you by the body. Not have to get a charger or cable switch and remote control.
You get a complete camera package.

Or as long as my left hand it used to touch the screen all is active. But once I put my left hand back on the camera to take my shot or shots the camera then stops the touch screen until I need to use it again.
left hand on the camera no touch screen. Left hand off the camera touch screen is active. Can be done with a infrared sensor when the left hand makes contact with the camera.

I will agree with that, but if we are looking a live view there is no nose in the way. Plus if the screen is user for more function then we do not need to look through the viewer. That could be removed also.

I think it is time for Pentax to take a quantum jump with software that can replace the mechanical buttons on the camera.
If mobile phones have touch screens and GPS nav systems why not Pentax Camera’s
User the screen in back of the camera for items like the Mode dial
When viewing a photo have a touch zoom fuction.
Tap the screen 2 times and go to live view.
Tap the right side of the screen and a vertical level
Tap the bottom of the screen have horizontal level With or without live view.

With removing mechanical buttons on the camera you free up space inside for better software that is user friendly.
Both advanced or beginner function window on the screen.

When looking at the place you plug in on the K20D it is not same as the AC76U.

Which one is the correct one to get for the K20D?
Both can be user on the K20D
