I could title this page Best Memory Card for the Canon T4i/T5i . but that would be link bait – this is more about comparing the couple of cards I had laying around to give you some ideas of the differences between cards and shooting RAW or JPEG.

I have been recommending the SanDisk Extreme 45MB/s Class 10 card for T4i/T5i and tonight I thought I would take a few moments and see how it compared to a few other cards I had laying around the house. My semi-scientific test was to stick a card in, shoot for 10 seconds on RAW and 10 seconds on JPEG and count how many photos I could get in that time frame. Bottom Line – If you are shooting JPEGs it doesn’t matter a whole lot but if you shoot RAW, and I recommend you do to get the highest image quality out of your camera, it matters a good bit what card you put into your Canon T4i/T5i (this also applies to other Canons and Nikon cameras too) Another component of the test that I didn’t record is the time it takes the buffer to clear after shooting, with the slower cards it is some time before you can take a burst again, much better with the faster cards.

 #mondaymorningshare - Were you trying to impress the ladies this week like this green winged teal? Visit photorec.tv/fb to share your favorite photo from the last week and check out all the submissions! It's a great way to get your work seen! * Captured with the Sigma 150-600 C as I wrap up my comparison vs the Tamron 150-600
 Deal Alert - http://photorec.tv/80dsale This is an unofficial price drop and probably won't last long! I am working on a video right now about why the 80D #dslr is still my pick for best all around camera at this price point and still a better pick versus the new #canon #77D. The owl photo I posted a few days ago was captured with the #80D at ISO 5000
 Another from last weekend's #owlstravaganza (I am so glad that hashtag exists) I hope to head back here this weekend with my kids to see these Short-eared Owls hanging out and as I mentioned earlier it is a great testing ground for my Sigma 150-600 vs Tamron 150-600 G2 comparison I am working on. * Captured with the Canon 80D and #tamron #150600g2 ISO 5000 (it was darker than it looks)

    • In my only semi-scientific tests, yes. I think we are seeing the camera buffer and write speed being the bottle neck here. I would like to run the test a few more times to be sure but at the very least it doesn’t seem worth the extra cost

  1. It it pretty weird that the 95 MB/s sandisk is slower that the 45MB/s however these are the facts! thanks again! Your tests make my day!
