Swivi3, display viewer, makes 10" out of NX300's 3.3"!
You can (same with NEX7) change card/battery without removing Swivi3.
Price of Swivi3 is $100/€80, hehehehe, 1/4 of Zakuto!
Newest model is Swivi4, but 50% more expensive than Swivi3.
Both are adjustable x/y/z, fitting ALL cameras.
Swivi is a "must have" :-) while taking movies aaaand against sunshine!
