Gail:
I just ran a few tests on my a510. This is probably the best 3mp camera for under $200, except for the L-O-N-G flash cycle.
Some people have said that flash cycle is fast with the LCD turned off. This is partially true. According to my tests, flash took about 2 seconds longer to recharge, with the LCD on.
With LCD off, the recharge light blinks only for a few seconds and makes you think that the camera is ready. But the flash is not ready at that time and you cannot take the next picture until much later. This varies with how much flash was used up.
In small areas, a 4x4 closet, the flash is not completely used up and it is ready again within 2-3 seconds. With LCD on it takes twice as long. In this case the time difference is quite noticeable.
In an open spaces the flash discharge is complete and it may take up to 12 seconds to recharge. In the latter case it takes only a couple seconds longer with the LCD left on.
I leave the LCD on because the trade off is only a few seconds.
You may want to confirm this and add it to your blog.
