Samyang just announced on facebook (Click here) that they will release the new 7.5mm f/3.5 Fisheye lens for m43 in September. And there is now also an official statement on their website (Click here). The lens provides a 180 degree field vision and is manual focusing only. You can also see the four very first image samples (again on facebook). Those images do look very good! We have no word yet about the price but it will be certainly much cheaper than the current Panasonic 8mm f/3.5 Fisheye lens. Click here to check the price of that lens: Amazon, B&H, Adorama, Olympus US store, FocusCamera, eBay.
One more editors note. Samyang makes chreap lenses with very high quality! The recent 35mm f/1.4 lens for Olympus is simply amazing. See the test results on a Canon APSC- done by Photozone (Click here). I do hope Samyang will make more of those lenses for m43!
Message to Samyang. Make some decent compact and fast primes and I bet you will sell tons of them!
P.S.: All Samyang lenses for Olympus can be found on eBay only and under seven different brand names (Click on it to see all Four Thirds lenses from the specific brand!):
