Just a short FYI shipping update on Canon's RF 100mm macro lens. Placed pre-order for this lens and tripod collar with B&H on Jun 1, 2021. Just rec'd notification from BH that lens has shipped and my PayBoo card was charged. ETA to my home is Wed, Aug 18. Hooray for that. Maybe product backlogs are looking better?? Meanwhile, the tripod collar remains on backorder, even though they charged my CC for it, as well. In the future will order accessories separately to avoid this anomaly.
UPDATE: Lens arrived today, Aug 17, one day early.
