Is the DOF using a digital sensor (e.g M8, Pana G1) any different than 
that of film?

In a question on Rangefinder forum, I was asking about using the Pana G1 
as the most economical way to play "digital M", and got into a 
discussion on "loss of DOF" with digital sensors.

I never understood that. With a crop sensor, isn't it just like shooting 
with a third of the 36 x 24mm frame covered?

The razor thin DOF of my Noctilux is still razor thin, just that the 
image that I'm taking is like cropping it to that of a 100mm lens. Or, 
to think of it another way, my Noctilux becomes a 100mm f1 portrait 
lens, a focal length that once was considered close to perfect for 
portraits.

And fortunately, with the Panasonic, I see what I'm framing.

Isn't that so, about the DOF?

regards
Vick
