Not quite sure what to make of it, or how I'd use it. However, the fisheye and wide-angle shots are the most entertaining of the photos shown.
Special effects are wonderful, but like hot peppers, best if used sparingly. It would probably take quite a bit of time to learn to use the lenses and filters in a non-gimmicky way.
Problem is, for me anyway, I'm still striving to master the E-M1, a complicated beast to be sure.
Thanks for your review of an interesting trail I otherwise wouldn't have known as much about.
Jules.
