If you've been on the fence regarding the EOS M, now might be the time to jump off. Canon has discounted the bejeezus out of it, dropping the price by 50%. Since Canon has recently updated the firmware to help with the slow auto focus, this camera is even more of a bargain today. You might not want to think about this one too long, as B&H is surely to run out of stock any time now. EOS M is $299
If they do sell out of the Black model, you can see if the white version is still in stock, as the sale applies to it too.
What this means is that Canon is likely preparing to release a new version of the M sometime in the very near future. I can't imagine any other reason to drop the price so drastically.
