Excerpt: This memory card comes free with the Canon 5D Mark III + Printer + Photo paper package. Holds enough Raw hi-res images for a portrait session plus more. If you're using this SD card with your Mark III, know that the camera will default to the write speed of the SD card, even if the write speed on your CF card is faster.
Excerpt: I give this a 4 because there is no mention of initializing on the packaging. Other than that, this SD card is good for the price. I use mine for filming short videos, sport games, and interviews. Works like a charm!
