I'm moving up from my Sigma 150-500 to a Canon f5.6 400mm prime lens. I've only taken a few "playing around" pics with it, but I'm looking forward to it becoming my main birding lens.

Does anyone know how well it performs with a Canon 1.4x teleconverter. I was wondering how well it auto focuses with the 1.4 between it and the camera.

My 150-500 is on ebay right now with less than 48 hrs left and has a couple bids. It's sale is going to help finance the 400 prime
