The Metabones Micro Four Thirds to Canon EF Speedbooster adapter was part of recent news, so if you're looking at grabbing a Canon EF Lens here's the current list of price drops via B&H.
Just a reminder that those Manfrotto Rebates will expire (this week) on Jne 15th. If you were looking to pick up a set of Video Tripod Legs, a Video Fluid Head, Video Monopod, and more, NOW might be the time to check out those deals.
I'm seeing rebates as much as $125 off retail price. Rebates include discounts on Manfrotto's latest Video Fluid Head with Bridging Technology - the MVH500AH Video Fluid Head, and also on their very popular 561BHDV Video Monopod (which BTW includes another $50 dollar gift card).
A few days left for these rebate offers, so make sure to check it out over at B&H (found Here).
