I did a quick AF comparison of the Olympus 45mm F1.8 and the Nikon 1 32mm F1.2. The lenses were used on an Olympus OM-D E-M10 and Nikon 1 V1 respectively. You can watch the video on YT: https://youtu.be/VIyhKmf4YvI
There doesn't seem to be much of difference between the AF speed of the Olympus...
Yesterday I recorded a video of me trying to pick up a damselfly with my finger from an aquatic plant and eventually succeeding. The damselfly stayed for several minutes on my finger and allowed me to record it from up close. :)
Recorded with Nikon 1 V1 and Nikon 1 Nikkor VR 10-30mm f/3.5-5.6.
