I don’t own any macro lens for my Reflex camera yet, but a little while ago, I got this Olloclip for my iPhone.
It doesn’t require any extra software. Just attach it to your phone and it will give you four different shooting features: wide angle, fish eye 10X macro, and 15X macro.
The only inconvenient is that it’s difficult to focus on a particular part of the composition, for it’s just a hardware attachment, so it’s impossible to control it with your fingertips like any other iPhone photos.
Apart from that, everything is great. It’s so small I can carry it everywhere I go and take fun pictures all the time.
Here are some of the photos I’ve taken until now with the two macro lenses. Click on them to see the complete image!
