I'm considering buying the Canon Digital Rebel XT. Someone suggested
that they may have heard that the autofocus on the camera doesn't work
as well as some of the other choices (such as the Pentax or the Nikon).
He had some difficulties, but he thinks it might also have been the
lens. How does the autofocus on that camera compare to similar cameras?

I've seen webpages like...

Have me wondering...

If you disable all of the focus points except one, you should have no
problems.

Autofocus is a tool. It will focus on whatever is the most prominent
item in your shot. If you are behind a fence in a zoo and shot the
animal, the lens may focus on the fence instead of the animal. If you
are at a hockey game, behind the netting at the end of the rink, the
lens might focus on the netting instead of the action on the ice. You
have to know when to use the auto focus, and when to turn it off.

Auto focus is a tool.

There was a problem with AF accuracy on some unquantified percent of
the 10D's but I've not seen anything mentioned about the Rebel having a
similar problem.

I would look to see if the actuator pin that moves the autofocus mirror is
plastic, or metal. The digital Rebel EOS 300d is plastic, and mine broke at
9000 shutter clicks. Not happy. I don't know if the XT is plastic or metal,
but supposedly the higher end cam's are metal. The function of the autofocus
is fine, its the long term durability I am questioning.

What "actuator pin" of what "autofocus mirror"? The only moving parts
in the system are the focus motors.

Of course he is, he didn't post "Damn my canon camera RULES!!!"!

How dare this guy ask a question here about a possible concern. Everyone
knows Canon has ZERO problems with their AF.

They use the same lens right? People seem to blame AF problems on the lens
used rather than the body used so he has a valid concern IMHO.

So much for the durability and resiliency of polycarbonate versus
metal.

Are you saying it may have trouble with some lenses? Or that some
lenses have trouble? Or that there is not problem other than how some
people use some lenses?

Well, one didn't say, and the other was a predicesor model. If there
was a problem with a previous model, the question is, was it fixed? If
not, then that would say that what I've heard can be discounted...

I'm someone trying to figure out if a concern about a purchase is a real
issue. I don't know why using the internet has to mean someone will
question your motives even when you are being quite sincere.

Different lenses are slower to focus, or may not focus at all in dim light.
But you will know it.

If you were all that sincere you wouldn't be quoting web pages that have
nothing to do with the Rebel XT. The date on one is from 2004 long before
the XT was released, and the other is regarding the 10D, a camera that is
two revisions before the XT.

So you feel the canon has not problems with focus, its just a matter of
some people not understanding how autofocus works? Why the attention on
canon (if this is common to all the cameras)? Because they are the most
popular?

So as I asked the previous poster, you feel the canon has not problems
with focus, its just a matter of some people not understanding how
autofocus works?

And you feel that people are focusing on Canon because they are the most
common?

That isn't that useful. Are you saying it may have trouble with some

Again, not giving any real help. These indicate a problem with a
predecessor model. Such problems can, esp. if not address, keep coming
up in later models? You feel that there may have been a problem with
previous models? Or do you just feel that one should be concerned with
problems in a similar model to what you are looking at?

>Are you just a troll?

Why do people, rather than look at why you might be sincere, try and
find reasons to be dismissive?

It's more of an issue of users expecting to much from any autofocus
system.

Use the center AF point and you won't have any problems.

And even if it was wear and impact resistance are two entirely different
things. But shame on Canon for specing the wrong material for the
application. Reminds me of my ex-wife's Ford Escort that had a notorious
problem with the inlet or outlet tube of the heater core constantly snapping
off of the core. The $150 OEM part had plastic tubes glued to the core
while the $30 aftermarket part had brass tubes soldered to the core.

Personal opinion:
If, after reading the published reviews, as well as other sites
discussing he camera, you're not sure if it is the camera you should
buy, then don't buy it. There are many other choices out there. It
won't bother other Canon users at all.

I would say all non manufacturer lenses can have probems
I had a Pentax MZ5 with a Sigma 170-500. It used to hunt a lot and was slow
whilst focusing. When I switched to digital I bought the 300D with another
Sigma 170-500 and a Tamron 70-300. The Sigma hunted and the Tamron was dog
slow. Bought a canon 100-400IS L and wow, Replaced the Tamron witha Canon
75-300 USM III (did not have funds for the IS) and dead happy with speed and
focusing capabilities. I have had no problem since fitting Canon lenses to
my 300D and 350D, just miss the 500mm though

Here's a site which discusses the 10D "problem" in detail, you'll
probably find it interesting. As mentioned earlier, the Rebel XT model
you are looking at doesn't have this problem (neither did most of the
10D's, but some did).

There are no OUTSTANDING issues with the XT. If you want the camera, buy it,
and use it.

If yours has issues you can return it to any REPUTABLE dealer. Canon bashers
have come up with some issues abourt the XT, as well as the '20 and he
original Drebel, but for the most part they are parroting anecdotal
experiences of people who :

1. had a defective lens

or

2. had a defective camera

or

3. dont know hoe to use a DSLR.


No camera is perfect, they all have some compromises, and it is up to you to
decide which compromise you are willing to put up with.

I think it is relevant. They speak to whether canon has a fundamental
problem in their focusing. You may disagree, but that doesn't mean
someone else isn't sincere. I tried responding with a post asking for
you to elaborate, but not luck

I'm sorry, but you have been one of the least helpful posters here. You
have done nothing but try to be dismissive and assume that nobody might
have a concern where you don't. When you do say something, it is a
short comment that really doesn't say anything.

It seems clear that using charges of "trolling" are now a way of trying
to silence posts that one doesn't care for.

Elaborate on what? There was nothing to elaborate on. Please point to one
report that suggests that Canon has a fundamental problem in their focusing.
I assume you know how to use a search engine. You picked a couple of sites
that discuss a camera that may as well be considered an antique in the
digital world and I pointed that out. I did the same as everyone else has
done but in much less waste of words. Do you really need me to type a 500
word essay telling you that you are referencing out of date material? If
so, I can accomodate.

It said everything that needed to be said, most importantly: "Those have
nothing to do with the Rebel XT." Again, if you have any sites that bring
up fundamental flaws in Canon focusing or specifically the Rebel XT then by
all means bring them up. Otherwise, you're just being obnoxious.

It seems clear that the trolls are "trolling" even though they don't think
they are.

BTW, did you try Googling on Rebel XT focus problems? If so, were the 10D
pages the only ones that came up? If not, how did you come up with those
10D pages? The Rebel XT has been out 6 months or so, you seem like an
intelligent person, don't you think there would be a wealth of sites
documenting any focus problems with the XT? And yet you only came up with
10D problems. Doesn't that tell you something?

Jesus, Rich, you'll grab any straw to make your point, won't you?
You're as bad as Stacey. Nobody has said the actuator is made from
polycarbonate, probably nobody except Canon knows what it's made of.
The BODY is polycarbonate - the same stuff they make aircraft
windshields from. Tupperware it's not.

Get a grip.

I don't know exactly what the material is (I don't have the camera, and
if I did I'm not going to take it apart to find out) but I'd say the
issue with the shutter doesn't seem to be widely reported.

But the Ford thing... yeah... Ford engineers are retarded at times.

Trolling, at least in all the newsgroups I've been in, refer deliberate
attempts to post in a way that stirs up controversy rather than a
sincere attempt to discuss and issue. It is not simply talking about
something controversial, posting something you don't agree with, or even
being wrong about something. You can't troll by "accident".

I must say that you are simply casting for way to label post as trolls
because you don't like them.

Yeah, I'm clearer on the 10D issue.

I've been looking around and all the professional reviewers I've seen
think the autofocus is good. OTOH, there is a small, but persistent
trickle of user complaining about it. That doesn't seem to be true of
the Nikon. Is it a symptom of problem with some cameras? Is it simply
that there are more Canons out there (and so more users to complain)?
Is it that the autofocus works OK, but is harder to use well? I don't know.

I like the 8 Mpixels feature, but I'm thinking of going with the Nikon
(what is the different between the D50 and the D70?), if only because
I'm afraid I will be overly critical of the focus if I get the Canon.

I've seen some Nikon measurebators that were just as bad as the Canon
ones.

In any case, get the camera that fits you, and for the love of god,
don't measurebate! You'll go blind.

A suggestion, if you think someone is being dumb (and clearly you are

maybe you should just not say anything rather than, for example, trying

I didn't until you started going on and on trying to justify your lame ass
choice of samples of focusing problems.

Look at my first reply and the respons to the first quoted text. You
gave me a short answer. I posted three different questions to try and
elucidate something useful about it and you responded with another
cryptic answer.

Look, if you think it is OK to attack posts you don't like as trolls (as
you seem to feel above), at least be honest an admit it (and if you feel
embarassed then maybe reexamine your bahavior). But also trying to
pretend you were being helpful just doesn't fly. I leaned something
real from this thread, but not from anything you said.

I any case, I have no more time to deal with immaturity on the net. I
have nothing more to say....

How could you know whether I liked your post or not when your post had
nothing to like or dislike about it? It completely lacked anything relevant
to your question. The reason I was terse in my original reply was because I
didn't want to spend any more time writing my reply than the very little
time you spent researching suspected autofocus problems with the Rebel XT.

You learned that a Rebel XT isn't a 10D?

It must be related to "pixel peeping", ie being _extremely_ finicky
about one particular facet of (in this case, digital) digital SLR
cameras and losing the context of whether the camera can do the job
asked of it.

Ah.

Unfortunately, when I get worried about something I tend to focus in on
it so I can see myself doing something like this without thinking. That
is something I'm considering, whether I might be overcritical of my
focus if I get a Canon, even if it is unfair....

It could be any of those things. It could also simply be the nature of
the autofocus algorithms at work behind the scenes. There isn't an
industry standard for autofocus; each camera manufacturer has their own
proprietary method for determining when a camera has an image in focus.
There could be a segment of the population that simply finds Canon's
focusing program to be disagreeable with their tastes.

Not everyone is able to handle a camera properly. We assume that the
complaints come from users who know what they're doing, but I wonder
sometimes. When you see that some people can't even frame a shot
correctly, god knows where the focus point(s) was/were looking when they
hit the trigger. Or they take a shot of a couple of persons and fail to
see that no focus point is on either person. Given that Canon dslr's
rule the lower segment of the market at least, some of them must be
owned by idiots.
