Nissin for MI shoe delayed until Fall. Metz folks in Jersey can't even answer when 44 for MI shoe will be available. The Sony 43 is heavier than what I'm looking for (already have 60 and want something around 300 grams or less). Have the 20 too, but it can bounce only for horizontal shots. I love Metz products. Still have and use 40MZ-3i and 32-Z2 for film.
