Paul (and others) The DOF-master calculator dial gives me 6.4 meter (21 feet) at 80mm (6x6) at f22. This is the value for CoC = 0,030mm. My table gives me 5.3m (CoC = 0.055mm). For 0.055 the chart values match my table precisely. I guess CoC should be different for each format (different enlargement). It's great idea to make a calculator dial for each lens(cab). I will do just that for my 6x6 lenses. All the best

Here is a link for a couple depth of field calculators - including a program, DOFMaster, which will let you choose format and focal length to print a circular slide rule device that you can carry with you to determine the zone of focus. Best of all.....it's free. http://dfleming.ameranet.com/ Paul ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, April 10, 2004 3:04 PM Subject: Re: Zone Focus - what is it? > In a message dated 4/10/2004 11:36:29 AM Pacific Standard Time, > [EMAIL PROTECTED] writes: > If anybody is interested, I have made a spreadsheet (Excel) on HFD and NL > for common 6x6 and 35mm focal lengths. > All the best > Jens > -------------- > Yeah, I'd like to see it.
