I bought the Olloclip 4-in-1 Photo Lens for iPhone 6/6 Plus from Hong Kong Apple Store at Festive Walk for HK$678 (S$117). If you are located in Singapore, Apple Online Store Singapore is selling it for S$119.
Olloclip 4-in-1 lens is a lightweight (35g) clip-on photo lens for your iPhone 6/6 Plus camera. It comes with two lens and each lens has two uses. The fisheye lens will give you a 15x macro lens as well and the wide-angle lens will give you a 10x macro lens. In total you will have four lens: Fisheye, Wide-Angle, 10x Macro and 15x Macro.
