Canon EOS 300d... focusing and shutter button problem

Hi, a a recent outdoor movie event I took photos in various lighting conditions, in darkeness at the end. My autofocusing was working because I recall difficulty getting the lens to "land" on an image focussed - I switched to manual in these situations. A few days later, I attempted to focus in AF mode, and it was sluggish. The first frame would autotocus and then all I could get was the metering info with the viewing screen. It didin't respond quickly. The lenses I use are EF 28-80mm and EF 100-300mm USM (non digital lenses). Today I tried again and the focusing does occur on AF (when shutter button half depressed). I tried these lenses on my film EOS 3000N and the lenses focus as I expect with the shutter button half depressed. Any suggestions to fix this sudden problem? I have had no problems in the 4 years I've used this camera. Oh, one more thing, I don't always see the red dots within the 7 autofocusing boxes.

    AF does not work at all when the shutter button is depressed halfway. The lens focuses only when the shutter button is fully depressed.

My EOS 300d blank images

That problem is normally associated with having a too high shutter speed when using flash. If it happens in any mode, with or without flash you may have a shutter blind issue.

Test the camera at various shutter speeds and compare the results. If this black area is consistant across different shutter speeds, send it in for repair. It is most likely the shutter curtain not making a pass across the sensor fast enough, still obscuring the sensor when a photo was taken.

Accessing internal memory on the Canon Digital Rebel EOS 300D

There is no internal permanent memory. There is a buffer that holds data momentarily while the data is written to the memory card, but the buffer is flushed after each shot or series of shots. Sorry.

EOS 30D is slow to fire.

Are you sure you aren't in the delay setting in drive mode? This camera has 2 delay settings, one for 2 seconds between when you press the shutter and when it takes the photo, and one with 10 seconds delay - often used when you want to be in the photo (e.g. self-portrait or group photo).

If you aren't in the delay mode, then I need to know more about your settings. What shooting mode are you using? What type of photo are you trying to take (portrait, landscape, sports)? Are you shooting indoors, outdoors, bright sunlight, overcast, etc.?

Problems with my canon 300d

Your sentence is not making much sense.
Turn the dial in manual to change the shutter speed
Hold the AV button and turn the dial to change the aperture
You can then press the exposure button (*) to see if your settings are too dark or light before you take the shot.

Is this what you want?

Bottom 2/3 of photo is black

It sounds like your autofocusing mirror is loose and obstructing the shutter.

Sometimes if you take photos against harsh light, it results in too much Contrast and makes the photos look in B&W. Please explain more details of the problem you are facing.

My 300D wont lock on a point in its AF setting

If you are unable to focus in broad daylight and it just hunts through the whole focus range without locking, then it sounds like a problem with sub-mirror pin (also called the second mirror pin). My 300D just had this problem and I had to send to service to get fixed. I sent to as they were at least $50 cheaper than going straight to Canon. Just got it backed and it works like a charm again.
