In the US at the moment there is a Olympus Lens sale on ang given the US dollar there are good deals to be had. I had my eye on BH website and when selecting a lens it showed up in the cart $200 cheaper. Unfortunately BH ran out of the 50-200 and new stock was $100 dearer which put the price over the magic $1000 when duty and GST become payable. Fortunately offer the 50-200 for $899.95 USD which is well under the $1000.
The lens come with Worldwide Warraanty ( I got the 12-60) from BH a few weeks ago. Arrived by UPS in 5 days!
