T4i Buffer Corrupted?


Hi All,


Hey, just got a T4i, and WAS getting 5 fps for about 20 pics (my card is slow) out of the box.

Now I only get a meager 3 pics at the 5fps speed, then about 1 fps.


Large quality jpg setting (No RAW).

No lens correction turned on.


An eye-fi 16GB (which I returned) had the same problem of only spitting out 3 rapid fire frames.

Does the same thing even without a card.  Behaves about the same at much lower res as well.

Using a 135 f2, and coming from the 10D body.



Any help is much appreciated.  -Mike








There are so many variables that I highly recommend re setting the camera to it's default settings to see how it performs PLUS i highly recommend getting a class 6 or better card from one of the big players (Sandisk or Lexar are good choices).
