It is true that this product consists of very simple materials, a big piece of rubber included the eye, a large magnifying glass to zoom in on the screen, a plastic frame with metal strips to hang the magnetic backing that attaches to the camera. frankly, when you unpack the product and we realize the content, it gets scared .. we say but what is that this bauble .. Well do not be fooled by the simplicity of product, I immediately tested out in the sun and there, what a joy to be able to put in the focus and adjust brightness without the sun bothers us. A product of design and use could not be more simple but largely effective. I took pleasure to make videos with my SLR (650 D) outdoors and in the sun. Before, it was frustration, false light on the touch screen or the slightest daylight distort me the result, suddenly the focus was unsuccessful and the object, or the person I wanted to film was blurry, because the development was done in front or behind the cible.Là it's just great, I conducted various tests and all were successful. Honestly, for the ridiculous price of the viewfinder, please do so, it will change your life if you love film and the sun is your biggest enemy.
