Help! T1i Continuous burst max 4fps

My T1i will not shoot more than 4fps in continuous burst RAW+jpeg. Battery is charged, noise reduction is auto. I've used brand new Sandisk Extreme 30mb/s and Ultra 15mb/s. I've tried changing a few custom functions with no luck. any guidance would be highly appreciated.

You're doing well, it's rated at 3.4fps.

The funny part I never understood is how these camera manufacturers can rate the FPS at 3.4 or 3.6578 or 2.984? Either it gets the full frame or not. lol. so the camera just stops after 3FPS and then just takes 4/10 of the next frame or what!? lol. werd

3.4 fps means each shot takes 1/3.4 or .29 seconds to take. So it takes .88 seconds to take 3 full shots.

darn.. what I meant was it only takes 4 pictures in continuous burst mode.. pauses then takes a picture every second after that.. in Large jpeg it bursts for a very long time...

It's called a buffer (temporary storage on your camera that holds photo data before the card reads it off your camera).

Your card/camera can only do those 4 shots before the buffer gets full... it takes time to clear it out again. The faster the card the faster you can clear out your camera's buffer.

Which is why it slows down. It's very normal.

If you want it to go faster for longer, then get a faster card.

The reason why jpegs can go for a long time is that each file is smaller and (therefore) takes up less space on your camera's buffer. ALSO this means they can be transfered to your card quicker... meaning the buffer doesn't fill up.

Hope this makes sense.

I think it's rated at 9 frames of raw only before the buffer fills. The + jpg you are shooting is moving larger images than just raw.

Yes and the RAW+Jpeg will probably give him about 4 frames before the buffer fills.

The more expensive cameras have larger buffers, so they can keep on for a longer time, before they have to pause to flush the buffer to the card.
Well, sometimes it's not a longer time, since some of them are a lot faster, but at least more images before they pause.

RAW only can do 9 frames, jpeg can pretty much keep going till 150 or something. but RAW+Jpeg takes alot of the buffer space

if its the same as the older xxxD's if you look in the viewfinder on the right side there should be a number there, for the xxxD I think this number goes to 9. This shows the remaining number of shots on your buffer so you should be able to compare RAW+JPEG, RAW, JPEG.

lol where is aravena, this is a double blunder

So is a maximum of 4 continuous shots in RAW+jpeg on a Sandisk Extreme 30mb/s expected? acceptable?

I think I'm gonna have to go RAW only.

The shots go straight onto an internal buffer, which is then written onto the card.

The quicker your card means you can clear the buffer quicker but so far it is quite hard (impossible maybe?) for data to be written to the card quick enough that you can maintain 3.4fps indefinitely.

Therefore however fast your card you are still going to be limited to 4 shots.

if your camera could write infinitely quick then your card would be the bottleneck
if you had a card with infinite writing speed the camera wouldn't be able to write quick enough, therefore causing a bottleneck

either way you are unlikely to get more than 4 shots.

Higher model cameras can shoot for longer and with quicker fps is because they have a bigger internal buffer.
