I mainly use the fisheye and wide for mentraîner podcasting with my smartphone Nexus 4. The result is quite good, the 4 corners are shaded but we really gain visibility angle. The rendering approaches that currently do NORMAN.
I also used the macro lens to photograph very small elements and it works well!
Anyway if you want to have fun for 10 ... do not hesitate, it's worth every penny!
PS: I had a scratched lens and I have requested the referral in three days the seller sent me the entire package. XCSOURCE thank you.
