I have tried few lenses for my iPhone. I love Hitcase lenses, they are not bulky and easily fits in my pocket while travelling. Olloclip is portable, easy to carry around. It's hard to find place for them while I am on air travel. I personally like Hitcase snap lenses!
This is Good smartphone but i use Gretel GT6000 and this is a wonderful phone with Long Lasting battery 6000mAh and you know this phone also have dual rear camera. This is a Good Looking and feature reach phone.
