Craig,

You said:  "...No Jim, that's not correct.

You're not reading the site correctly.

Your desired CoC depends on sensor/film size, viewing distance, print size and visual acuity of the viewer.

http://en.wikipedia.org/wiki/Circle_of_confusion

Based on those variables you choose a CoC that suits you. After you have chosen the CoC you can then vary aperture, focal length and subject distance to estimate DOF...."

I am aware of that and I suppose I should have included the variable factors as well. I was just simplifying and I should not have done so.

I raised this entire matter only because Fuji did something that no other manufacturer has done; i.e., display the depth of field in the finder. When I saw how narrow the display was, I raised the question, to wit, is there something unique about the Fuji XPro, did Fuji make an error, or are they just being super conservative?

I called Fuji-US this morning and spoke to their Pro camera adviser. First the good news. He has been watching this discussion on DP Review with interest and was glad to talk to me. Now the bad news. He has no answer and directed me to e-mail Fuji technical in Tokyo and assured me that they do pay attention as shown by their often prompt response to customer complaints and/or suggestions by issuing upgrades. So, I did so. I really don't expect a prompt response, but I hope I get some answer some time.

In the meantime, I got an answer from my inquiry to Montana Media, the producers of the iPad app. called " Simple DOF ", a rather clever application. He advised that an update was, or will be made to the application to show the C of C for the Fuji X series as .02 instead of .005. So, either by testing, or operating on faith, he is treating the Fuji X as no different than other APSC format cameras.

When I get my XPro-1 on Monday, I'll assume that the DOF is no different than other APSC cameras and then after shooting, Ill check the results. Not very scientific, but practical.
