In Point and Shoot cameras, you can frame the picture in the LCD then take the shot.

It doesn't appear that this works the same in the DSLRs (Rebel XTI). The Best Buy guy didn't know if it did or not. THe picture will appear in the LCD after the shot was taken so you have to look to the viewfinder for the shot.

Can someone confirm either way.

you HAVE to use the viewfinder there is no active LCD because there is a big mirror in the way on DSLRs

Right, it's not a live-preview, unless you're talking about the newest generation of cameras (only a few DSLR's have one). most will only show the picture you took, not what you're looking at.

Point-n-shoot, the image sensor is always exposed, so you can frame it in the LCD. DSLR, it is only exposed when you hit the shutter and the mirror flips up out of the way. You must use the viewfinder.

There are some exceptions, but for the most part you use an optical viewfinder in a DSLR, which is a very good thing.

if your buying a dslr then you need to first never compare it to a P&S.

and second take some classes so you understand how the dslr evoled from a film camera and fstops and apetures

The sensor in a DSLR camera is behind a mirror that only allows the light from the lens through when you depress the shutter.

anyway i cant understand why you woudl want to use teh LCD to shoot, the viewfinder is always gonna be more accurate,

the *shipping now* olympus E-410 is capable of live preview, though you can't use the viewfinder and it blacks out for autofocus (the AF sensors are up in the pentaprism/mirror area), and the *shipping next month* olympus E-510 does the same (in comparison with the E-410, the 510 is slightly larger, with a bigger battery, and NMOS-shift image stabilization). E-410 currently runs $899 with dual lens kit. the olympus E-330 has live preview that works either by using the main sensor (no autofocus) or using a secondary sensor near the porroprism (autofocus and the ability to use the viewfinder). problem with the E-330 is that the viewfinder is particularly dark due to some of the light being split out of the prism to the secondary sensor.

the panasonic/leica DSLR is based on the olympus E-330 and also has live preview (it's expensive, but the 'kit' lens is fscking spectacular)

ummm

digital? check
single lens? check
reflex mirror? check

the E-330 is a digital SLR.

with the new oly dslrs, you can get 10x magnification using the LCD, which could be useful for macro focusing. additionally, the LCD offers 100% coverage, whereas the viewfinder is probably ~90%. plus, you can shoot from other than eye-level, offering non-traditional perspectives.

How is it not a true DSLR? While the viewfinder is the most accurate, I would love to have a position-able live LCD like the ones in the Olympus. It would make taking those impossibly low/high shots much more convenient. And macro shots won't require having to sneak my entire head next to a bug.

unless they made a 2nd one the first was a fixed lens one

You can use either the viewfinder or the LCD.

You are grossly misinformed.

the olympus dslr is a dslr. but id stick with canon or nikon and leave olympus for the little boys :)

for the lenses primarily. and canon's sensor technology is pretty much at the top of the game.

a) it was interchangable
b) nothing says a single lens reflex camera has to be interchangeable lens

the new NMOS panasonic sensors that olympus is using supposedly look really good. and the olympus lenses appear to be as good as anything canikon produce.

now, if only olympus didn't price their lenses so high. an olympus 35-100 f/2.0 costs $500 more than the canon 70-200 f/2.8L IS and nikon's 70-200 f/2.8D VR. that's pretty ridiculous.

olympus also doesn't have enough primes (though, only pentax seems to be truly interested in primes, and theirs are at weird focal lengths).

Olympus has had DSLRs that do that for the last year or so.

why would you buy an olympus dslr ;)

Because it produces the best out of the camera results for my style of shooting.

Onlympus lenses are easily a match for Canon's in terms of quality. If you mean availability, then yeah, it's easier to find low-price (but also low-quality) lenses for Canons (the kit lens on the DRebels is a great example of a lens that is spectacularly adequate), but Pentax, Olympus, and Sony/Minolta all have lenses that will match the best that Canon/Nikon can offer.

Sensor technology... meh. Raw shots from the 10mp DSLRs all look about the same. Canon does have much better in-camera JPEG noise processing though. Of course, a $5,000 1DSMkIII will be better than a $500 Olympus, but that's not a brand issue, that's a market segment issue. Pretty much all sub-$1,000 cameras are equal. There are pros and cons to each and it's essentially impossible to buy one that's a "dud".

So how do the DSLR cameras that provide previews on the LCD work? This seems counter-intuitive to the whole SLR principle.
