I have seen several post recently about using extension tubes with this lens so I have knocked up this table of min/max focus distances which maybe of interest to some people.
The distances were calculated with lens on a tripod using various combinations of the tubes I have, I moved the tripod to get the min/max AF distances and then measured with a tape rule from target to front of lens so not scientific but hopefully will give a good indication.
Cheers Roy, I have been entirely baffled by extension tubes up until now.
Thats great Roy, I just put on order from Hong Kong, my Kenko Extension
