Are you maybe using any kind of screen-protector to your new 5D Mark III?

While I will agree a screen protector is not entirely neccessary I enjoy not having to worry about scratching the screen. That said I found that the giottos schott glass screen protectors work great. They transmit nearly 100% of light and do not seem to alter the image at all. They are very strong too. I have hiked and traveled in very dusty environments with this without a problem.

+1 on the Giottos Schott glass protectors. I've had them on my 50D, 5D2 and now on both 5D3s. Easier to install and much cheaper than changing out the factory production piece that's already there. B&H carries them, in stock.

you are paying all than £££ for the 5Dmkiii whats a few more to protect the screen, its for peace of mind more then anything else.

When i picked up my new 5D i put the Canon LCD screen protection on before i left the shop
