Our daily challenge - (From Laurie) A word I recently learned, Andragogy simply refers to adult education.
Show us something you recently learned, are currently learning about or studying or something you want to learn more about and...have fun!

I used my Yongnuo 100mm lens for this, a learning exercise. Its auto focus is somewhat random, so generally have to use manual focus (see comments) which is a challenge with poor eyesight :-) Straight from the camera, zero editing.

To the photographers left side there’s an AF/MF switch for engaging/disengaging the internal micro-DC motor, once this lens doesn’t support a full time operation; every time one wishes to manually focus, he/she/it must disengage it from the motor. What’s really curious is how the ring mechanically turns: a counter-clockwise movement produces a clockwise spin on the focusing group, in direction of the minimum focusing distance; and a clockwise ring movement produces a counter-clockwise turn on the focusing group, aiming for infinity; very confusing! It’s comical to see the distance window moving opposite to the external focusing ring, and it asks for a slight learning curve, made even more important given the questionable autofocus performance.

Thanks Chrissy. This lens delivers faithful colours, but is very tricky to focus.
