I made some shots during last trip... but to be honest I don't know wich with and witch without the MFO-3
I can try to find some but without waranty.

But if you have time, I'll have some after 10 days diving in Lembeh next month.

No worries — take your time and try to dig out some images 🙂 I’m curious to see them.

Look at the subject distance in the EXIF, it will be in the range of 0.6m plus unless you are pushing right in next to the lens, It shows up in properties under details tab, scroll down to camera in Windows explorer.

I browsed through the pictures in LR. The one right is without the MFO-3 (Canon RF100) The subject to big it was a shot to make test.

The left one is (sure to 99%) with the MFO-3... more or less the same distance as the other. The frgofish moved a little

The distance are really not right. It change from 1 m to 4, 7, 18 and infinite I don't know how it is calculate... Water, lens and MFO-3 bring the exif to madness
The left picture is 4m the right 1 m....

I searched this picture made with the RF100... Distance 7 m like the frog fish left

This distance is near the reality not the frog fish
