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!
