Thank you! I confess I am not a big macro practitioner, and conditions were not ideal - these were taken in a very hunid greenhouse at the Royal Horticultural Society (RHS) gardens at Wisley. It was heaving with other visitors so a monopod, let alone a tripod, was out of the question. Everything was therefore handheld wide open, using the evf. I tend to focus approximately, then rock gently back and forth until I hit my desired plane of focus.
