The olloclip 4-in-1 is a quick-connect lens solution for the Apple iPhone that includes fisheye wide-angle and two macro lenses in one small convenient package that easily fits in your pocket — and the palm of your hand. It connects to the iPhone within seconds so you ll be sure to capture the image you want. If you don t see the picture you re looking for just flip it over to switch lenses. The fisheye lens captures approximately a 180-degree field of view and produces some striking images. The wide-angle lens is great for when you need that extra field of view approximately double that of the normal iPhone. Choose the lens based on the level of detail you re looking for.
