Jeeze, another gizmo I dont need. Stop down, unfocus, shoot the sky then zoom the lcd and pan the sensor. Who needs this tool? The camera does a fantastic job of showing me whats on its sensor. I have a twirlygig brush and a blower bulb to clean it when needed. Thats enough space and weight in my camera bag. I just bought a Canon 85 1.2. It weighs 10 pounds or so. I need less stuff in my bag to compensate for its mass
