like Canon S1/2/3 when you can get 17x zoom with add-on tele lens and 0.5x
with wide one...

A 7mp Sony H5 set to 5mp gives optical quality 14x zoom, set to 3mp,16x
when using Smart Zoom. Add the 1.7x zoom lens and you get 856mm
equivilant, Panasonic has this feature and some new Canons have it. The
new Panasonic FZ50 should be the equivilant of 17x optical quality set
at 5mp. I believe all these cameras rate higher than Samsung.

Why are there so few cars that do over 150 MPH?

Lens design is very much a compromise. Improve one area only at the
expense of something else. The larger the zoom ratio, the more
difficult the job, and the more you will suffer somewhere. You may
have to add elements, with more ghosting and flare. You may find
curvature of field more of a problem. This is particularly the case as
you go towards the shorter focal lengths with increased ray angles at
surfaces. So I believe most camera companies figure the tradeoffs
become unattractive around 10X or higher.

Better to let folks who want that kind of ratio select an
interchangable lens camera, and lens mfgs go for a wide zoom range
removable lens, where they can sell the lens over a wider customer base
(many brands of cameras).

It's difficult, and expensive to design, and manufacture zoom lenses with
that range, that maintain quality, and low levels of distortion. That is
why the majority of P&S cameras have 3X zooms.

firstly, please don't mix optical and digital zoom, no matter how it's
called. IF we speak of optical + digital, we'd get 48x on S2/3 plus
converter comes all the way to 72x zoom.
BUT...we were talking of OPTICAL zoom and nothing else. That smart or
whatever some companies call it is nothing else than digital zoom. Useless.
Also that increasing of zoom by decreasing pixel count - that ISN'T optical
zoom, but merely fooling of customer THINKING it has optical zoom , while
indeed it's called cropping and can be done on any PC with any camera shots.
Sony is just known for their smart-ass novelties and making fool of
innocent, no-proffesionally learned people

Hello, Protoncek:

I agree! Sony's products had steadily worsened, long before it entered
the digital photography arena.

i've read one review of (don't exactly know model) sony dSLR and first of
all, reviewer said never go anywhere without manual - since it has so many
features, you get lost in them pretty easy, and second, don't anyone hold
your camera, since he/she may press a button and you'll take 10 minutes to
figure it out how to set all back---

Hello, Protoncek:

In all fairness to Sony, its new "Alpha A100" DSLR (if that's what
you're referring to, above) is a pretty advanced model. Thus, some
extra intricacy is to be logically expected.

couldn't exactly tell, i think it was above model. I would agree
partially... see, cameras are (i hope) ment to many people, not jsut to
above-average scientists who can quickly understand and use all
god-knows-what features. OK, it IS good to have many features, but it's
definitely not good if there are TOO damn many. Then you get lost in all
those functions, not to tell that each and every one you need you have to
look couple of minutes to get to it or find it. I'd say two things are
possible here - either reviewer has cronical disease against Sony, or since
he/she definitely held a LOT of cameras, he/she pretty well knows what is
talking about. Too much is too much, i guess. I'd have to hold and test it
to be true judge---i just wrote what i've read, it's not my opinion, neither
i decided against Sony because of this purpose. There were other stuff which
make me decide for Canon, noise figure is one of more important ones.
