Benefit of this firmware update

  • It corrects the phenomenon that AF does not operate properly when some lenses that are not compatible with the MC-11 are attached.

Lenses that are not compatible with the MC-11

We will continue to consider ensuring stable operation of lenses that are not compatible with the MC-11. Therefore customers who are using the MC-11 can enjoy photography as much as possible with their own lenses even though there may be some restrictions. However, please note that due to the characteristics of the products, accurate operation, including AF, is not guaranteed with lenses that are not compatible with the MC-11.
