Thanks Martyn for your answer.But I think that with preset or auto WB control, we can only get medium quality color for our clip, for best quality it must be manual WB control like in VX2100 or HDR-FX1, thanks for your answer

Who told you this? The FX7 has complete manual control over WB, like its brethren.

Vinh i told you the fx 7 does have full manual control,in some cases i use it but for myself i find the outdoor acuracy better using auto on my cam but you may prefer manual.

I knew that from Camcorders - Independent Camcorder Reviews, Ratings & Comparisons in product details of FX7, if there is full manual WB controls in FX7 then it will be my first HD camcorder.Thanks for all of your answers

Not sure what you were reading, but the review on that website includes the quote:

"The FX7 offers two custom white balances, A and B. Each is set by selecting either setting A or B, then pushing in and holding the jog dial until the icon stops blinking. Manual adjustments appeared accurate in their balance."

Sounds like full manual to me.

Thanks a lot to everyone who answers me, perhaps manual WB control in FX is at 2 custom WB, I've missed that detail. Anyway thanks a lot.Would you please show me link to download FX7 user's manual ?
