Reply To: Nauticam MFO-1 (mid-range focus optimiser)

[John]

Hi — just saw a review of the MFO pop up on uwpg. I am curious as it says

Attachment: The MFO-1 attaches to your lens via a
standard filter thread (typically 67mm) and comes with a spacer ring for
compatibility with SMC/CMC lenses

The photo shows the MFO on the port with a spacer ring

Curious as I believed the MFO was not for stacking with CMC / SMC?

Cheers John
