Loupe Macro Lens
You may of seen the Olloclip and other mobile lenses - whilst they are a great idea. They are $70 - which for a frugal student is not ideal. I recently ordered a dirty cheap £2 ($3 approximately) jewellers loupe off Amazon and it’s surprisingly good image quality for the money. Hat tip to Ben Furneaux for pointing this out!
