Don't know about the SD cards from Sandisk, but the new Ultra II and the Extreme III CF cards are both the same speed. I think the Exteme III has been dropped.
(at least from the CF line..). I also don't know that a faster card does anything for a T2i...it's buffer speed, not card speed that seems to make a difference in how fast and for how long a high speed shooting burst will last.


I agree completely with the "less is more" concept regarding storage. 2x 8GB cards cost less than one 16GB and makes more sense. 4x4GB would be even less money and be more convenient as far as keeping track of where files are.

I have read the rationale about why a 32GB card is great so HD video can be shot for a continuous hour (or whatever). I was in the motion picture business a lot longer than most here have been alive. But my word isn't needed...watch any movie and see how often a scene is continuous for more than 6 or 7 seconds. It happens, but it's the exception.

The only good use for an hour of continuous video is to get guests who have over-stayed their welcome to leave by boring them to death by showing any home video that goes on for more than two minutes. ;););) (which happens to be how long an 8mm spool would run in total....and two minutes is an eternity when watching home movies/videos of another family's kids or worse...an "art film" by someone who thinks that an hour cut can be interesting..torture!!​!!
:D

Peace,
D.

AFAIK, the T2i is limited to 12 minutes of continuous 1080p footage. I've read this is due to a 4GB file limit on FAT32 formatted media.. other camcorders break up the clip into multiple files to bypass this limit. Ohhhh well :D

Hello every one

I just order my Canon T2i with Canon Pixma PRO9000MkII Inkjet Photo Printer $899 after $400; I need money for buy lens and accessories for my first SDLR camera. I will sale this printer ASAP, if no one buys my printer I have to return to B&H.

This is my first SDLR camera, I will learn more in this forum. I have couple question if someone can help me.

Please teach me how to get the right SD card for this T2i, I read a lot in this forum but make me confuse.
My T2i will be delivery on May-6 it came with 1 lens, if some professional photographer tech me for basic lens I need for indoor and outdoor and can take picture for my sister wedding in next 2 month.
My friend gives me his 430EX.
Is this 430EX work with my t2i?
Man I feel like I need a lot of time to sturdy more about how to use SDLR camera.

Ultra II is noticeably slower then the Extreme III card in my T1i, i think it's too slow i've missed alot of shots with the Ultra after the buffer runs out the Extreme card still get an ok frame rate.

Do you have a media card reader you could use to benchmark your card? I currently have a few 8GB cards that can do a sustained 16-18MB/s write

I used HDTune (external link) to perform the benchmark

:D

I don't use video, I was just repeating what I read. So I guess the guy that needed a 32GB card so he could shoot continuously knew even less than I figured! LOL

12 minutes is a VERY long time to shoot one contiuous video shot anyway. I worked in the motion picuture and TV industries for over 40 years. I don't think I ever saw a 12 minute scene in all that time. Even on TV...live news, sports and interview shows I don't think I ever saw a technical director stay on one camera for more than a half minute..and even 30 seconds can seem like an eternity....(The possible exception of using a steady feed on a "magic" trick for obvious reasons).

Well, I guess this must be for SD cards...My Extreme III CF Sandisk card is labeled at 30MB/sec - as is my newer Sandisk Ultra II - same 30MB/sec

Peace,

Wow, what a nice picture! You must have a really great camera!
