Yes, you need to be on your game compositionally when only the center AF point (with or without Expand) is available. Much better to be on a tripod then…. And the Mongoose M3.6 is perfect for the 100-400 II. AF is always slowed with the loss of one stop of lights and image quality is always somewhat degraded. But today’s lenses are so, so sharp that making professionally sharp images with either TC should be routine for anyone employing excellent sharpness techniques. artie

I’m very interested in your “Stuff” follow-up as I have been using the 100-400 II, the 7D II, and the 1.4X TC III, hand-held since the 100-400 II was released.

Single-point and expanded single-point on the 7DII is sometimes a challenge (for me) when going hand-held, but when I photograph birds they like to move when I close in.

I’ve also noticed AF (faster) and image quality (sharper) seems much improved when the TC is not used (though it’s great with the TC attached).

Life is full of trade-offs.

Best,
Scott
