Having had some considerable success with the Opteka 10x HD Macro lens I had a look at their website:


Some good stuff there, the fisheye looks particularly interesting, 6.5mm efl for APS-C could mean 5.2mm for 4/3rds! All lenses appear to be available in 4/3rds.

I am afraid you are calculating backwards... :)

6.5 mm will still be 6.5 mm with a 4/3 mount. And that equals 13 mm for a 35 mm sensor. (compared to the 8mm Zuiko FE = 16 mm equivalent)

So it is a tad shorter that the Zuiko, which makes me wonder if it still is a full-frame fish eye or that it loses its corners on a 4/3 camera.

But pricewise it is not bad, if the quality is there.
