Digital Rebel LCD focus blurry

[RichardClinton]

When I try to check for fine focus on the LCD screen, the 4x magnified image
is a little blurry and I can't tell any difference from in and out of focus
areas until I look on my computer monitor. Is there some adjustment to be
made for screen focus? Thanks.

I've never been able to check focus with the LCD, even with zooming. It just
doesn't work.

Hang on! Are you guys talking about the EVF focus, cause I have no way of
focusing through the LCD when taking a shot. Or am I confused as usual?

Mine is too, though when I got the 17-85mm IS lens, the magnified view
on the LCD wasn't nearly as burry as with the kit lens, though it still
is a little.

No, we are talking about post-shot viewing on the LCD. You can zoom the
image with the button at top right of the camera up to 10x the original
image size, and navigate round the image with the < and > buttons.

While I can't say for sure, this is what I *think* is causing it:

Doing full-quality decompression of a full-size JPEG from the Digital
Rebel not only takes a fair amount of processing cycles, it also takes a
pretty good amount of memory in which to store the image. Because of those
constraints, when displaying the image on the LCD screen, a full-quality
decompression isn't done - the camera does a "quick & dirty" decompression
to obtain an image of a resolution suitable to the LCD panel, or maybe a
small bit above. When you zoom in on the image, it's just magnifying that
low-res version, *not* going back and performing another decompression of
the original.

Zooming in on a photo shot in "raw" mode seems to be a bit sharper on the
LCD than one shot in JPEG, but still nowhere near what the LCD *could* be
displaying if fed the proper information. Because of that, I imagine that
the camera simply takes a down-sized version of the RAW data to display, and
simply magnifies that to let you "zoom".

As always, I could be wrong.

Ha! I was reading this thread and trying to imagine how these
newfangled DSLRs got an image to the LCD on a continuing basis. Pellix
mirrors? Mirrors that cycle > 30 Hz continuously? Noiselessly!? Walk
around looking at the LCD instead of the viewfinder, like the non SLR
digitals? I was starting to get excited!

What the hell have I missed!

Well, youve missed some, but you're in good company, as many others have
asked the same question. DSLR's do not have preview on the LCD. They
have optical reflex finders as in film SLR's, and the LCD will show you
the shot after you have taken it, together with histogram info etc.

DSLR's have mechanical shutters, and the sensor is not exposed until the
shot is taken. Additionally, the mirror would be in the way if the
shutter wasn't there, or was open.

Aw shoot! You mean that DSLRs are nothing more than SLRs with a digital
sensor instead of emulsion film? Here I was all set to get excited
about some automagical whizbang I'd never heard of before! Dang!
Finding out that you knew what was going on all along sure is boring...

At least with DSLRs you get an instant return mirror. The non SLR
digitals blank out the LCD during image storage, which means that if you
are following the action, you'd better be using the optical viewfinder,
for whatever good that would do. With shutter lag, you won't get what
you want anyway.

Wonder how many people that are used to the viewfinder digitals actually
expect DSLRs to have a continuous LCD readout? Wonder how many of those
know what an SLR camera is? RFL!!

Simple Light Rugged camera? Well, they used to be, at least compared to
a Speed Graphic. Now, how about Super Luxurious Robot? And then if you
ask the elite snobs that only tote a Leica M, it's probably Stoopid Loser
Rangefinder-wannabe.

What's that you say? Three strikes and out? Oh okay...

You're up to bat, Rudy.
