This is what I am talking about.. This is an excerpt from another online forum talking about the 2.5 LCD screen.. It is about the 5D but the 5D uses the same 230,000 pixel, 2.5 screen as the 400D (see Canon's website for specs) but the 5D has the additional digital screen on top, the 400D does not.. read the second paragraph ! The link to the full article is at the bottom of this reply.
The following is quoted from an online forum..
When you first see a 5D you may initially not notice that it's somewhat larger than a 20D, but you definately won't miss the significantly larger rear LCD. This is a big size improvement over previous Canon screens, and is identical to the screen that Canon has put on the equally new 1Ds MK II. The larger screen not only makes image review superior, but because screen text is also commensurately larger that aspect of camera operation is also enhanced. Clearly (pun intended) this screen is going to become the norm for future Canon cameras.
But before it does so though Canon needs to do something about the screen's performance in bright conditions, such as in full daylight. While shooting with the 5D in the intense and almost cloudless daylight of Greece I was also taking snapshots with a Sony T7 ultra-thin pocket digicam, which features a transreflective screen, which is, by coincidence, the same size as that on the 5D. While the Sony screen actually remains visible even in direct sunlight, the Canon became so washed out as to be almost unusable
. Canon needs to give their future cameras an LCD screen that provides photographers with state-of-the-art technology. The new screen on the 5D and the 1D MK IIn, while larger than on previous models, get a failing grade when it comes to usefulness outdoors.
