here is an image i took in my dark walled bedroom w/ a 60 watt (equv) compact floresent light bulb. i took 5 minutes getting the focus(and apeture etc) Right cause the AF beam wants to focus on the touch screen and not the words like our eyes can do and the flash would just kill it.
the glare i guess is pretty accurate, but if you look,there is also a big circle without any glare, so while reading i never notice any glare cause i just subconsciously move the glare away from where im reading by 1 or 2 degrees rotation
