To all the Batis 2/40 CF owners: Thank you very much for your patience and
understanding!
Once you’ve installed the update, the ZEISS Batis 2/40 CF will only
automatically stop down at preset aperture values between f/2 and f/2.5 at a
focus distance of between 24 and 65 centimeters – in extreme cases (minimum
object distance) to max. f/2.8. With an aperture value of f/2.8 and up, the
aperture will remain unchanged across the entire focus range.
What’s more, the update will enhance the focus accuracy when using the camera
’s eye AF function.
Please follow the link to find out more about the update and the free
download for your ZEISS Batis 2/40 CF:

看起來是改善之前鏡頭在對焦距離太近時，會自動縮小光圈的問題
