Sounds like something for a consumer oriented DSLR. I have found touchscreens for the most part still aren't as nice to use as their pushbutton counterparts. I'd love canon to prove me wrong though.

the only way id want their to be a touch screen is for selecting different items to change VIA thumb/finger wheels.

The little joystick thing doesnt work all that well but that is the only thing id want replaced with the touch screen.

So as well as cleaning nose prints off the screen, you'd have to clean masses of finger prints as well.

Yeah, I agree. The current button setup is fine and cleaning up the oil from nose prints is enough to deal with already!

Problem solved - just change the settings on the touch screen with your nose.

I don't even like touch screen on point-and-shoots.

Please god no

Touch screens are also porous and therefore not going to be weather sealed. You won't be able to get it damp or close to any water.

Take Care,

Err, what? Touch screens do not have to be porous.

I guess not all of them are porous, but all the ones used before were. I guess they have to use one of these types?

Resistive Touch Screen Monitors

A resistive touch screen monitor usually has a coat of very thin electrically conductive and resistive layer of metal. When pressed, the change in electrical current can be measured and the input processed by a computer. While very affordable they only offer about 75% clarity, they can also be easily damaged by objects that are sharp. Resistive touch screen monitors are the most popular types of touch screen monitors used today. They are usually not effected by dust or liquids which make them very reliable.

Surface Wave Touch Screen Monitors

Surface wave touch screen monitors use ultrasonic waves to process inputs from the screen. Ultrasonic waves flow over the touch screen, when a person touches the pad at a specific location, the wave is absorbed and immediately processed by the computer. While not as common as resistive touch panels, they are used in certain applications. Dust and water can contaminate a surface wave touch screen so it is important to keep the screens properly maintained.

Capacitive Touch Screen Monitors

Capacitive touch screens are coated with indium tin oxide. This material provides a continuous current across the screen. The current is precisely controlled throughout the touch pad and can be measured by the computer processor, when touched; the screen is able to send the processor specific coordinates to input information correctly. It is important to note that specific objects can only be used on capacitive touch screens. You can not use a stylus or a pencil for instance; usually you will need a bare finger. Capacitive touch screens have high clarity and are not affected by dust or liquids.

Infrared Touch Screen Monitors

There are two types of Infrared touch screen monitor screens, the first reacts to infrared or thermal waves (heat), unfortunately this technology is slow and does not work well with cold hands or objects. The second type of Infrared touch screen monitors use vertical and horizontal infrared sensors around the perimeter of the touch screen. Creating a grid, the touch screen is able to pinpoint the exact location of where the screen has been touched and send that information to the computer for processing. Infrared touch screen monitors are very durable and are used for industrial and military applications.
Touch screens have been around since the 1970's, in fact the technology was invented in 1971. Most of the patents for touch screens technology were established during the 1970's and 1980's making them no longer current. Today any manufacturer can produce touch screen technology without having to pay royalties or licensing fees.

too much risk of gettign screen busted and the screen in general not working.

Very bad for scuba - do not want!

i disagree. i think the joystick is a godsend in terms of selecting the AF points - if i lost it, it'd be tough for me.

I enjoy using the touch screen on my phone, but I can't see it being faster or more efficient than the dual wheels on my 40D for selecting settings while shooting.

I'd be curious to see how it was implemented though.
