Issue with Canon Autofocus?
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... http://www.canon-dslr.com/ http://www.luminous-landscape.com/es...oversies.shtml Have me wondering... |

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

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. roland |

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. |

There is a sub mirror behind the mirror you see when you take a lens off. This sub mirror has to do with the autofocus and it is driven by or activated by a little pin thingy kind of down at the bottom right corner. When the main mirror you see is flipped up out of the way of the sensor when you click the shutter, the sub mirror pops up too, out of the way. If the little (plastic) pin mechanism is broke the sub mirror stays down and blocks about 2/3's of the shutter. It is possible to manually flip the sub mirror up and take pictures but then you can't you use the autofocus. This is all contigent on the Rebel 300 and the XT being the same. I have had two camera repair shops tell me that the piece in question is plastic on the Rebel 300 and metal on higher end camera's. I don't know if the XT is the same or not. If it is the same, and its plastic. Watch for it - it sucks. $200 fix |

I don't think the plastic price is much different, its mostly labor. The price was closer to $175 before tax. If I could get my hands on the part, I would be tempted to tear the camera apart myself. I have not actually paid for this fix, just had it quoted by two different repair shops. There is this looming possibility that Canon will fix this out of warranty problem, with maybe the metal cam piece too, so I am told by the repair shops - fat chance I think, plus it would take 4 to 6 weeks or some gawd awful time like it. regular shops want 2 weeks to fix it.
