Yesterday I went to the park and was shooting some people playing soccer, i was using my 75-300 IS USM lens, I had it on Continious shooting but it would only take one picture at a time and it woudl take about 5 seconds to load that to my cf card, the pictures were a little dark, so when the lighting is bad does it take longer to write to my cf card, i have a 1GB card and it writes at 80x so i dont know what the problem is, and it only happens when the lighting is bad,

If your exposure is 1/2 second, it would only take one every 1/2 second, no matter how fast the camera is. What was your shutter speed? Low light makes longer shutter, which makes slower "continuous."

If you're shooting JPEG at high ISO (on Auto in bad light, you'll be at high ISO) the files will be much larger due to the higher noise levels. That will increase the write times. Shutter speed only plays i when it gets really long. Since you were shooting sports, I would guess your shutter speeds weren't the issue.

thats probably what it was, i was using Program AE, not shutter priority,

so when im shooting in bad light, i should use shutter Priority, what about the dark picutre, if i Up the ISO, isnt that my problem long write times, and unable to shoot continious.

Did you have a flash attached or using the pop-up flash? I've experienced this with a fash attached. The camera waits for the flash to charge before firing even in continous mode. Infact, if the flash isn't fully charged, you'll receive pictures underexposed too.

Another possible issue may be the slow lens. The cam needs to lock focus before each shot, and that takes longer with a slow lens in marginal light. The slow lens will also force you to use higher ISO to get the same shutter speed.

Another thought:
You've got a fast CF card, but if the camera's "card activity" LED stays on for several seconds after a singe shot, it's obviously not writing fast. Your JPEG file size should not be over about 4.0MB, even if they are noisy. You should be able to write a file to the card in less than a second, and in any case you have to fill the buffer first. As anexperiment, try formatting the card in the camera, then try similar bad-light burst of shots. Did that improve the write speeds? If so, the card was "fragmented". The cam needed to write the files in small chunks.

I will try the CF card formated, and i was using the pop up flash, i dont have a attachable flash yet, is my lens slow, it was damm expensive, i hope not, my jpegs are 3.5MB, , in day light im fine, i can burst plenty, its just in low light conditions, ill go shoot tonight and play around with the settings, see what happens,
thanks

That 75-300 lens is slow. f5.6 @300 requires fairly long shutter speeds in low light (even in bright light). You'll have to bump the ISO if you want faster shutter speeds.

Yes, it's expensive but that's for the IS which will give you a couple of stops leeway to avoid camera shake on handheld shots.

Ah hah! If you had the on-camera flash popped up, the camer was waiting for the flash to re-charge. That can take a few seconds, especially since it was probably firing at full power.
