Got this clip-on fisheye lens off eBay recently, and like usual, gonna make a demo on it for the benefit of those who may be interested in getting one.
The photo quality is really acceptable like most I would say, but the one thing I like about it is it's flexibility, it can be used on any phone, or rather any mobile device, your tablet, your huge phone, even your laptop/macbook! I would recommend it, it's pretty cheap when I got it, it's about uh... $7.50USD.
Hope the video's useful to you guys!
