| ownership: | I own this lens |
| compared to: | Mieke 6.5mm ƒ2.0 "almost" full-circle fisheye, fits µ4/3rds directly, and is much smaller and lighter as well as a stop faster, but it crops the circle on top and bottom, and is manual focus only. |
| price paid: | 172 |
| positive: | The only full-circle fisheye available for smaller sensors! I used a Canon EF version adapted to µ4/3rds. |
| negative: | When adapted to µ4/3rds, autofocus is very slow. This may be an artifact of the particular adapter I am using. Lens is rather big and heavy compared to similar others. There seems to be a lot of flare around the outer edges, often shown as a blue border. |
| comment: | I suspect that the Mieke is intended for APS-C, but oddly, comes with a native µ4/3rds mount, whereas it appears the Sigma circle is intended for µ4/3rds, but comes with any mount but. So confusing! |
