LOMO Right Mirror Spy Lens Attachment 49mm
Many photographers are addicted to street photography. Go unnoticed when shooting requires skill and mastery. Most people pay attention to the photographer, especially if you shoot DSLR camera, which has large dimensions in comparison with compact cameras. When a person sees that his shooted, he immediately changed. This is the psychological moment, a person wants to look good, and it immediately begins pose for, sometimes without realizing it himself.
This attachment was invented to facilitate the photographer shooting unnoticed. Rather people notice you, but do not realize that you shoot them. The principle of such attachment is very simple. It is screwed onto front of the lens.
It has a 45-degree mirror inside, enabling the photographer to take a photo of a subject to the right or left (or up/down, I suppose) of where the camera is apparently pointing.
The image would be reversed, of course, because of the mirror. Research indicates that there might be some vignetting (dark corners) on the image. These spy lens attachments are produced by different manufacturers and are of different quality and price. I came upon a head of Soviet Right Mirror Spy Lens Attachment. Produced by LOMO. My copy has a seating thread 49mm. The barrel of the unit rotates to align the opening accurately toward the subject. This feature proved to be very convenient. You can capture the image on the left, right, top, bottom and at any angle. I mounted it on the Olympus Zuiko 50 mm 1,4, which has a same filter thread. Photographing people with this attachment is actually easier. You can stand next to someone at a distance of 1 meter, and he did not realize that it is photographed.
This survey is one important feature — the image would be reversed, because of the mirror. You can fix this in a graphics editor.
LOMO Right Mirror Spy Lens Attachment Image Quality Test
Test image on Nikon D3100 and Olympus Zuiko 50 mm 1,4 at f/ 5,6 without attachment
The same parameters, but with an attachment. (The image is reversed for clarity). Excuse me, the bottom left corner closes my finger. Consider the 100% size. Tree crops without and with attachment.
As we see the quality of the image decreases significantly, and is equivalent to the quality obtained at cheap digitall camera.
