On A Serious Rangefinder Compact Camera article (137 comments in total)

Apparently the concept of a concept is lost on a good percentage of photographers.

That said I'd buy one of these in a New York minute.

The inclusion of a position on all manual controls that enables electronic controls is inspired.

Of course, I shoot a Pentax K-5 with manual A lenses with AF confirm and beeps turned off. So I'm already getting as close to this concept as I can get. I suspect Easycass would approve :)

Oh, and don't make the damned thing too small! :)

In reply to:

viking5: Very interesting article. Thanks a lot!

I think there are two different concepts at work here...

DOF, which has been explained well here in the article and the comments, and which is dependent on aperture, focal length, and magnification.

The other is POF - plane of focus. While it is necessary to have sufficient DOF to keep the subject or desired parts of the subject in focus, excess DOF may be necessary if the POF is ignored or mismanaged.

The need for excess DOF because of mismanaged POF results in longer shutter speeds, higher ISO settings, and/or smaller than necessary apertures...all of which work against you.

While the two are related, they are also two very different things to manage and get right in the composition of a quality macro photograph.
