Spying is all about faking – there is thrill, but at times you may get grilled! While spying you always fear being caught, especially when youâre taking pictures with the SLR, and that big zoom pointing straight at your target. In situations like this, either you trust your legs (run), or carry this Super-Secret Spy Lens. This $50 fake lens attaches to your SLRâs zoom lens, giving you the freedom to shoot around 360 degrees (left, right, up, or down). For this, it has a secret cut-out on the side and a precision mirror assembled inside. In short, look straight and click anywhere.
