FINALLY got a chance to play around with the new toy. Everything hand-held. Did prove to myself that with the 1.4TC, hand held at 1/125 is kinda rough
But, even hand held with or without TC, this lens is a keeper. Expect with tripod, it would be even better. And, I (like everyone else) wait to see the firmware update. The 5diii did not autofocus at all with the 1.4TC on this lens.
Attached is jpeg right out of the camera with no PP at all (400mm 1/250, iso 500).
