having a closer shortest focus point ?

I wonder if there is a way to minimise the focus point.
When the EX1 is at the wider zoom, with iris full open, I can't get the focus closer to 50/70cm (haven't made a mesure).

I need to be able to get focus closer to that.

Maybe the MACRO mode can do this ?
In what range can the focus point be set then ?

Maybe I can add a lense (French word for that is a "bonnette") to the front of the lens to change the minimum focus point ?

Thanks.

Replying to myself...

The MACRO mode does everything I want. The only trick is you have not to be on full manual focus mode.
Move to assist focus and you're OK.

I'll post some footage soon.

Now - who would have thought that macro did that... ;-)

don't be sarcastic... :)
I tried it without success until I found you musn't be in full manual focus.

Sorry - just couldn't hold back. These things happen to the best of us. It's hard to memorize all that is written in the manual after only one read through.

Sebastien,

A diopter will do what you need to do here. Look at our 86mm diopters with an 86-77 step ring. You could also use other step rings to use this on other cams as well. We also make this in 1.6+ and 2.6+ variants.

I have a calculation file available that will give you the minimum focus distance with the diopter applied.
