I don't see how a flip out LCD can affect focus time.
However, a long optical zoom lens will lengthen focus time.
The only disadvantage to a flip out LCD is a little bit of added weight and it adds cost to the camera.
I was ready to purchase a Canon SX10is for both its price (($350.) and its cool flip out, tilt LCD.(no more glare rendering it unreadable) but hear this feature drastically slows its focus time as well as other problems. Any disadvantages or advantages with this feature? Lou from Montana
