The new (pictured above) Leica Q3 multifunctional protector + built-in grip + Arca-Swiss plate that was announced with the Q3 43 seems to be recalled, according to this post on Reddit:
“I am writing to inform you that the Leica Multifunctional Protector for Q3 and Q3 43 has been recalled by Leica Camera due to a design flaw. We are more than happy to provide you with a return label so that you can ship it back for a full refund.”
The new case is no longer listed on Leica’s official website or Adorama, and B&H Photo stopped taking preorders.
