Olympus' tactic of playing down the optical performance of this lens need not be necessary. Even though this lens only costs £90 and is little more than a body cap with some glass in it, it is still capable of delivering decent quality images. Those who fancy experimenting with the fisheye look but don't relish the thought of forking out proper fisheye money, this lens is ideal.
Overall, this lens is fun to use, thanks to its compact size and fuss-free operation.

The center performance is actually pretty decent. The borders are Okayish whereas the corners are very soft. Lateral CAs are significant but not terrible either.
This ultra-thin, ultra-lightweight lens has surprised us with more than decent images that only suffer from soft corners and comparatively high levels of chromatic aberration around the edges.
