In order to record HD video on the T3i, your memory card will need to have a Class 6 rating or higher. No matter how large your memory card is, video clips are limited to 30 minute segments. Class ratings represent the minimum write speed for a memory card. But this is not particularly revealing. My priorities here are cards that not only perform well in the T3i, but also have a combination of reliability, out of the box, good memory size range, and good value for money.
I have also not included all the cards that work on the camera. Memory card manufacturers are constantly releasing new models of memory cards. And because of how the market works, these newer, faster cards can sometimes be cheaper and more readily available than the older, slower versions. I will do my best to keep this list up to date. Many of them are available in storage sizes ranging from 8GB to GB. They all work in the T3i and the choice between them largely comes down to the convenience of not running out of space to take new photos.
For most users, 32GB and 64GB are probably good choices in terms of cost and convenience. It is also not designed to be a complete list of all SD cards that will work. I am focusing here on cards that meet these criteria: fast enough for all functions of this camera; from a reputable and reliable brand; available in retail stores; and good value for money.
However, many new brands have entered the market and are giving tough competition to these brands. You should note the type of use you have. If you only capture photographs or are a beginner, you can go with the Micro Center SD card. I hope you liked my coverage of the Best SD cards for Canon t3i. If you have any suggestions or doubts, drop them in the comments below. I know that standard HD uses only a small percentage of the sensor and the total data captured is therefore somewhat less than one might expect.
I believe Canon suggests Class 6 cards as a minimum spec for the HD video feature. With respect to shooting speeds, since I don't have the camera yet it's a little hard for me to comment.
JPG files are so small to start with that with the fast card, it may be possible to shoot non-stop with no slow downs. Of course, to your point, that assumes the internal processor can keep up. If the processor is the bottle neck, then a faster memory card will not help after a certain point. Looks like I'll have some testing to do :.
Here is a link to a video which clearly shows the improvement on the Nikon:. It is clear how long it takes the camera to save to the SD card. When they step up to the SanDisk, the performance boost is really noticeable. Another good reason to consider UHS-1 cards is to future-proof your card. It looks like the UHS-1 standard will be the wave of the future and as camera technology advances, more cameras will be able to support it.
When the T2i came out with a minimum class 6 for video, it changed my perspective and my next memory card purchase was class 6. I feel that it is a good idea to buy memory that is faster than you currently need so that you will not be stuck with obsolete memory as you upgrade your camera. Of course, you have to consider cost also. Since it is so new, UHS-1 is pretty pricey right now.
When you get down to the nuts and bolts of photography, the results depend on the 'nut' behind the camera! Brilliant post , its quite interesting that the T3i doesnt support the MHz bus speed. I wonder if the 60D supports UHS bus at all? Did you call or email support? When I asked again for specific information regarding the capabilities of the T3i, I was told "Canon has no published write speeds on any of our DSLR's" and that "The faster the memory you place in the camera the faster the cameras buffer can write to the card.
The only 'useful' information given to me was "We recommend using memory cards with a Speed Class I wrote back asking to forward my question along to someone who could answer specifically if the T3i would be able to take advantage of UHS-1 speeds, hoping someone could confirm what you have posted here about the camera supporting UHS at the MHz bus speed.
Unfortunately I was told there was no one to forward my question to and that UHS was simply untested with the T3i at this time. Having read this forum has made me even more confused. It seems that the UHS-1 card would be better than the standard class 10 cards. However, I am confused which cards offer this combination. I was looking at Sandisk Extreme and Lexmark Professional.
Would anyone be so kind as to clarify this for me. The Canon T3i is compatible with an optional BG-E8 battery grip, which can double capacity with two rechargeable lithium-ion battery packs.
The grip also accepts AA batteries. Canon recommends a Class 6 card or faster for recording HD movies. UHS-I compliant cards are supported, but the camera does not take advantage of their increased bus speeds.
Check the shopping link above, cards are really cheap these days, so no reason to skimp. Canon T3i Performance Tweet Share. Navigate Review Jump to review page Worst case buffer clearing time.
Slower cards will produce correspondingly slower clearing times. Slow cards may also limit length of bursts in continuous mode. ISO sensitivity and noise reduction settings can also affect cycle times and burst mode performance.
Time to capture while forcing flash to fire. Metering pulses from flash often slow shutter response. This mode usually shows no speed increase with our static subject; we have no way to measure performance with moving subjects. For most cameras, shutter lag is less in manual focus than autofocus, but usually not as fast as when the camera is "prefocused".
