SLT-A65 Pixel Soldier remote triger
They are tough to get off the first time you do have to supply some amount of force. there is no release button. but after it's been on and off a few times it'll be easier and mine have held up well since I got them.
I think on your camera you need to look through the menus for an item called setting effects and turn it off. this will allow the display to not be affected by the camera settings which would allow you to see quite well.
