So, if you want to take photography to another level on your iPhone 6s or iPhone 6s Plus, check out the accessories that we're presenting below (in no particular order). In case you're wondering, all these products also work with the older iPhone 6 and 6 Plus models.
iPhone 6s and 6s Plus accessories that let you take creative photos
1. Olloclip 4-in1 Lens system
Buy from Apple
2. Moment lenses
Buy: Moment tele lens, Moment macro lens, Moment wide-angle lens
3. DxO One
Other highlights of the DxO One are its high ISO (up to 51,200), and the fact it allows you to shoot RAW photos, which can be edited with the DxO image processing software that's included in the package. The camera also comes with a rechargeable Li-Ion battery, and micro SD card slot (card not included).
The DxO One certainly produces images that you could never take with just an iPhone 6s or iPhone 6s Plus, but it's quite expensive: it costs $599 if you want to buy it from Apple, or $549 if you're purchasing it from Amazon. That kind of money can get you a standalone DSLR or mirrorless camera (for example, the excellent Sony A6000 costs less than $700, kit lens included), so you may want to think twice before spending it on the DxO One.

4. Camkix Universal 3 in 1
