Damn dust!

too true blue

and information theory makes sure that the milliwatts of transmitted data
are received about as accurately as possible

Nor is there anyone there changing the lenses, or much dust in the vacuum
of space!

It's enough to make me seriously consider returning to film until
digital
makers solve the dust problem.

On Earth-based astronomical telescopes the sensors are sealed in a
dust-proof compartment and the optical front of the compartment is placed
far outside the focal depth of the telescope. Doing that would solve dust
problems in DSLRs too, but would make the cameras unwieldy. That's why some
manufacturers have resorted to tricks like vibrating the sensor to loosen
dust.

Many amateur digital photographers don't even know what sensor dust looks
like. For those who boast that they've never had a sensor dust problem:
stop down to F22, manually focus at infinity, over-expose by one stop and
shoot a picture of cloudless blue sky. Then load your image into Photoshop
and choose Auto Level. Now go cry when you see how much dust you've got to
clean off.

Professional photographers, such as myself, often shoot under precisely
controlled lighting, and sensor dust tends to show up then.

Yeap, it was way too much effort to check the sensor before shooting 650
frames, or when cleaning the lens. Yeap, much easier to hand the film over
to some processor and let them screw up the negatives and complain about
them instead. Of course, if you were shooting film would you have taken 650
frames?

Mike,

One of the reasons I own an Olympus E-20 is that the main lens is
permanently attached. The sensor is never exposed to the outside air, and
dust never reaches the sensor. I have two additional lens, the wide angle
and telescopic lens, that screw on to the permanently attached lens. I'm not
sure how many other lens are compatible with this setup.

The E-20 also has a see through the lens view finder as on SLR cameras, even
though it also has a LCD monitor. So, I compose all my shots through the
viewfinder the same way as one does with a SLR camera with removable lens.

Why can't digital SLR cameras have some kind of permanent filter at the
point that lens screw on, thereby keeping the sensor from becoming
contaminated!!

Just by as many digital bodies as you have lenses, and you'll never
need to expose the camera to dust.
