Getting ready for church last week, I noticed the crape myrtle full of bees. Good light, a fast lens, and...un-bee-lievable. (Sorry...)
The bees don't seem to be able to leave these flowers alone. Not great for the flowers due to the narrow DOF, but I was impressed with how well the 5D Mark IV nailed the focus and stopped the wings. Probably would have been better at f5.6, but I would not have been able to get the wings still without getting higher ISO. Live and learn...
