The lens press release with official price and specs will be released tomorrow (Tuesday November 15 at 5-6 am London time). Olympus Japan already added the lens in their database.
By the way we already have two 17mm primes that you may consider to buy instead of the 17mm f/1.8:
1) If you don’t care a lot about high image quality but more about tiny size than you may go for the Olympus 17mmf /2.8 at Amazon, B&H, Adorama, Olympus US store, FocusCamera, eBay.
2) If a big lens and no electronic AF and aperture doesn’t bother you than consider the superb and super fast Nokton 17.5mm f/0.95 lens (here on eBay). To easily find the best price on eBay you can also sue our little Slidoo tool (login to change country). Right now for example you can find a good deal at Fotomundus (Click here).
