Almost every lens has a more or less round “aperture”, the opening that lets light through to the sensor or film. Most modern lenses have aperture blades that open and close to change the size of the opening. You can see the aperture blades in this photo. Larger apertures obviously let in more light in a given period of time and smaller apertures let in less light in the same period of time. The size of the aperture opening is one factor that determines the exposure. Just as important, the size of the aperture helps determine the depth of field in each image.

The names of the companies change on a regular basis, but the scam is the same. Sad to say, a lot of people actually fall for this nonsense.

The Starscope Monocular, It Is The Same Old Scam

Starscope Monocular Telescope ad.

We’ve been down this road before (see the first link at the end). The scam works like this. Pick an inexpensively made product from China, jack up the price, make up ridiculous and false claims about the quality of the product and what it can do, and sell it on dozens of web sites using ads thinly disguised as articles. Go to the internet and grab professional photographs created with high dollar professional camera gear and put the photos in the ads to give the impression the photos were made with the Chinese product. And for good measure, say in the ads that the product was designed by American or German engineers and manufactured in the U.S. or Germany. Create fake customer reviews to go in the ads, and for good measure, create fake reviews sites to endorse the quality of the product.

They grabbed professionally created photographs taken with professionally photo equipment and passed them off as iPhone photos created with the fake German lens.
