I have the new XF 70-300mm on order and am trying to decide between the 1.4 and 2x converter. I will be using lens + converter mainly for wildlife/bird photography. Yes I know that the 2x will drop my max aperture by 2 stops, and the 1.4 by 1 stop. I'm wondering if any one has actual hands-on experiences with these converters. I would love to hear your observations.

Received mine a couple of days ago. This is going to be a great lens for macro as well as bird photography (have the 1.4x converter on order). This is a shot I took yesterday with the XF70-300 (0vercast, late afternoon) at 300mm from minimal focus distance (about 2.5 ft). On tripod, ISO 2000, F/10, 1/450s
