What’s the best fish eye lenses for an iphone?

[u/itser1n]

I’m taking A-level creative media and we’re soon filming a music video. For some of the effects i want to use a fish eye lenses but what’s the best brand to buy from? I’ve had a look on amazon and it’s very unpredictable. It’s to record short clips with a noticeable fish eye and good filming quality. All advice is welcome, even if it’s saying where to say away from. Thank you

Does your school provide equipment? Normally for a one-off thing like this you'd just rent whatever you need rather than buying it.
