Digital Camera World Verdict

The Funleader Cap Lens is very small, very nicely made and ultra-simple to use. Unfortunately, its optical quality is pretty poor, but you may still fall in love with its heavily vignetted soft-focus look, in which case it’s an interesting novelty that can give your images a look that’s unlike anything you’ll get from a regular lens. And did we mention it’s cheap!

Body cap lenses aren’t new – we have an Olympus Body Cap fisheye lens that performs beyond all reasonable expectations. The Funleader offers an angle of view almost as wide, at 18mm, but captures a corrected rectilinear (non-fisheye) image. It really is barely thicker than a body cap, though its aluminium construction means it is somewhat heavier.
