t4i low frame per second

Hi all,

I just purchased a T4i (with 18-135 STM) and am very happy with it, BUT I was expecting 5.0 FPS for more than 3 frames (I believe the burst is 12 frames using jpeg). No matter what settings I choose, I cannot get it to go for more than 3 frames at 5 FPS. Tried manual focus/one thousandth frame rate/S3 quality (thumbnail size). I set it to jpeg + RAW and still get the same burst of 3 frames before it drops down to 1 FPS. Does anyopne have any advice?
Thanks,
Alun

Doesn't seem right. My t4i goes like all get do. What kind of memory card do you have. Have to tried a low level format?

I fomatted the card when I got it. Not sure if there was the option of low level format? I will take a look when I get home. The card is a 32 gig Sandisk extreme 45m read and 45m write. I also tried a 2gig generic I had lying around with the same results...

If you have it set to Jpeg + Raw the max FPS is going to be 3. Look at page 334 of the manual. It'll explain the drive mode and FPS.

Jpeg+Raw = 3fps
Jpeg Large/Fine = 22 (30 with a UHS-I card)
Raw = 6

Also take a look at the chart on page 87. That should clear things up for you.

Re: t4i low frame per second

I had already tried changing the settings you mention with no luck.

I also tried reformatting the card at low level as suggested by DSHAPK, but that did not work either.

However, I found the option for resetting to factory defaults, after which time I could shoot at 5 FPS seemingly forever at Large Jpeg. Yipee!

I then went through the options and set at least 10 items to other settings (but kept it on Large Jpeg). Magically, I could only shoot 3 frames again at 5FPS...
I cannot remember which settings I changed (I did NOT set anything to RAW).
I performed a factory reset again and could shoot at 5FPS forever again...

If I get around to doing the research about which setting caused the issue, I will post it here.

Thanks for your assistance,
Alun

Re: t4i low frame per second

Large jpg you should be able to get a fair amount of shots in before the camera bogs down. Large plus raw is another story. It in essence captures two frames per shot, which is why the camera bogs down.

Re: t4i low frame per second

Perhaps the reason it bogs down is a too-small buffer and maybe a slow image processor.

I would hope, for the sake of a relative who just got a T4i, that the reason here is an option choice. A raw + jpeg buffer depth of three shots doesn't seem to be right for a body with good specs and a price to match.

It is most certainly an option choice.

Once factory reset, with a 45m/s write card, I seem to be able to shoot continuously at 5 FPS (I got way past 40 shots before I gave up ) and this was with Large Fine setting.
I am now VERY happy with my camera.

If you enable bracketing, then the shutter will give you 3-shot bursts.

Raw + jpeg or just jpeg?

I think the auto-noise reduction feature, for one, will slow the camera down.

You were on the money.

I went through the settings last night and found that it was the high iso noise reduction setting. I had set it to maximum, which limits the burst to 3...
I then found the statement on the bottom of page 124 in the manual.

I found that enabling the setting for "Lens aberration correction: Chromatic Aberration Correction" was another cause for slowing the continuous shooting frame rate.

The 4th wrench in the menu, 'clear settings'

Also, I've found that turning off the chromatic aberration correction will make the burst speed go longer than 3 shots

Is it that hard to find in the manual? I looked under R for 'reset' and right there was 'revert to default settings, page 210' and on page 210 are three simple steps. Perhaps if English is not your first language, 'revert' didn't sound like what you needed.

I second that.  The Chromatic aberration correction causes a very big delay.

Re: t4i low frame per second

Remember to Disable "Highlight Tone Priority". I believe you find this is the more obscure "Custom Settings". As other have said, it's crucial you also Disable "Chromatic Aberration Correction" and "Lens Correction".

Happy Shooting.
