Hi there,

I know this is an odd question, but does any of you know Elphel's "Circle
of confusion" size?

We'll have to make sure our focus is alright when we shoot, so I was
looking at ways of doing this.

Here (http://www.dofmaster.com/dofjs.html), if I use the settings for 1/3
inch and 1/2 inch sensors (the closests we'd have for Elphel's Aptina), it
gives values between 0,011 and 0,016 mm.

If I use this program though (http://sourceforge.net/projects/dofview/)
that allows me to use a custom sensor size, it results in a 0,005 mm Circle
of Confusion for Elphel's sensor (at full frame).

Which one should I use?

Thanks!
