Hi all, I'm a newbie in this world. I've bought a Canon G7 camera,
and
being used to analogic ambient I would like to know about DOF in
digital one. Help please!

Some digital cameras have a sensor the same size as a 35 mm lens so
the image produced with a given lens will have the same DOF and FOF
(field of view). Others have smaller sensors which will differ just
as a half frame film camera would.


Have a read through these two links for additional info about crop
factors, perspective, etc.:

Useful links, expecially the first one.
