If it's the amount of control that determines the absolute in cameras then
I
guess a P&S designed to let you choose shooting between available light or
infra-red spectrums with the push of a button, and using manual focusing
and
zoom rings on an 11mm-320mm (+macro) f/2.0-2.4 Zeiss lens must be the
ultimate
in control, along with all the usual shutter, f-stop, !00-3200 ISO, and
other
manual controls. I'm accurately describing one of my own P&S cameras by
the way.
No, that's not the ultimate in control. Some of the P&S cameras that can
run
CHDK today are the ultimate in manual or automated control. Some of their
controllable options easily beating even the $12,000 dSLR bodies being
sold this
year. Can you manually choose what colors you'd like on your
under/over-exposure
viewfinder overlay or by what limits that you want that under/over
detection
sensitivity? Can you control up to 1024 areas of your viewfinder, their
sampling-rates, and sensitivity levels in each region that you want to
detect
subject-motion to trigger your shutter? Choose between 7 different
live-histograms? 108 different video-compression options in 2 different
flavors?
Can you design your own cropping and composition masks for your viewfinder
in
any colors you want? This list is extremely long so I won't mention them
all,
there's a whole CHDK dedicated web-site to describe all that you can
control on
your CHDK-capable camera. The scripting options also allowing for
automated
control of the camera's manual features that no other cameras on earth can
equal
(such as 96 steps per f-stop for EV and flash levels). If these P&S
cameras only
had IR and UV options too ... sigh ...
If it's control that determines the best of all cameras then you're really
going
to have to look into the P&S models now and in the past. I've not found
one dSLR
yet that allows for the amount of myriad ways that one can control a P&S
camera.
This includes being able to control the ways that it can record
stereo-audio and
videos too. Put a higher quality lower-noise sensor into any of the
high-quality
super-zoom P&S camera that I've already bought and that's all that anyone
would
ever need.
While you're trying to control the limited features of that dSLR, would
you
PLEASE do something about controlling that obnoxious sound they make so
that
cameras are allowed back into public performances? Thanks. That's another
control option I get to have. I can control if I want my camera to make
noises
or not and how loud I want them to be. My shutter can sound like a
whinnying
horse or round of applause if I so choose (though a phaser firing sound
for the
delete button is kind of fun). You have zero control over the sounds your
camera
makes. You have one sound output option available clearly labeled
"Obnoxious",
which anyone near you can read. You do realize that the d/SLR is the main
reason
that cameras have been banned so many places, don't you? The only people
on
earth that like dSLRs are the people that choose to buy them. The rest of
us
know better and are more considerate and respectful of all others.
