Min. Aperture of prosumer compacts

[Guest]

Hi Group,
Are there any prosumer digital compact cameras that have a minimum aperture
of more than f8? I cant afford an slr but what use is f8 for landscapes??
Regards

Anything smaller than this with a small sensor would be so blurry, that
would be useless. The small sensor cameras have mega DOF anyway so that
isn't a concern. F8 on one of them is more like f22 on a 35mm camera if not
more DOF than that.

What they said....

Do a Google search on diffraction, small, CCD, sensor.. or words to
that effect. Think f16/f22-ish instead of (digital) f8. (I can't
believe I just made such a generalisation, but what the hell..)

Hi,

Due to the sensor size of most prosumers, any shot taken with f8 - bar macro
work and extreme close-ups - will have a depth-of-field that will cover a
small European country.

... but will equally start to show "soft" pictures due to diffraction

Even if you get a cheap point-and-shoot like the Kodak CX 7300 I have, you
won't have to worry about depth of field, it's sufficient.

I believe everyone so far has talked about the small sensor size used in
consumer cameras. This is only indirectly related. It is because of the
short focal lengths of the lenses used with the small sensors that actually
results in the greater depth of field at a given aperture. Depending on the
actual (not equivalent) focal lengths of the lenses, f/8 will provide more
depth of field than you would get with the equivalent lens on a 35mm camera
at that aperture, and possibly even when the 35mm camera's lens is stopped
down all the way.

Even more. On better P&S cameras (e.g. Canon G series) with 1/1.8"
sensors, f/8 is like f/40 on a 35 camera because the sensor is 1/5 the
size of a 35 frame. Less expensive cameras may have even smaller
sensors, with even greater DOF at f/8.

Hi there.

I have taken successful Landscapes at f5.6 on a 35mm, and they have been
accepted into Exhibitions.

Never mind the theoretical problems. What do the landscape pictures look
like? Do they show any signs of lack of D.o.F.?

If you have not yet bought a Camera, then borrow one from a friend and try
it out.

My wife uses a Fuji S5500 which, I suspect, has a rather small sensor. She
is not skilled in the theory, but just likes to take pictures. There is no
problem with D.o.F. in any of her Landscapes, and I have printed them up to
10 x 8 inches. When she does produce one that I really like, I might well
try printing it at 19 x 11inches. That Camera should not be able to produce
a good picture at that size, but there is really only one way to find out.

Too many people in our hobby worry too much about what might or might not
work. I know a bit of the theory, but try not to let it get in the way of my
picture making. The best way to find out if something works, is to try it,
and then look at the picture before deciding if there was a problem.
