The Fastest SD Cards for the Canon 7D
This is a part of our SD/CF/XQD Database.
The data in the table below tracks the time (in seconds) it took to write 20 RAW and 20 Fine Large JPG to the memory card. Timing commenced when the camera’s card status light illuminated, and stopped when the light went out. Each test cycle was performed three times, and the average is presented. Lower numbers are better.
The figure in the Burst column represents how many RAW photos the camera and card take in 30 seconds. Higher numbers are better.
Prior to each test, all cards were formatted within the camera. The same scene was photographed under the same illumination for all tests. The identical camera settings and lens were used throughout.
Card | Type | RAW | JPG | Burst |
SD | 9.18 | 3.69 | 49 | |
SD | 8.23 | 3.77 | 46 | |
SD | 7.51 | 3.91 | 51 | |
SD | 8.02 | 4.00 | 52 | |
SD | 13.79 | 5.50 | 41 | |
SD | 10.49 | 4.08 | 46 | |
SD | 9.71 | 3.65 | 48 | |
SD | 9.05 | 4.27 | 48 | |
SD | 8.56 | 3.71 | 50 | |
SD | 8.86 | 3.74 | 50 |
I have a 7D and love to shoot on it, but I think this is meant to say CF and not SD, as there is no SD slot on a 7D. But the Lexar CF cards do seem to be very fast with raw files on my camera. Thanks for sharing this.
Please make a reference to what does the numbers mean.
And it should say CF..
Please clarify this post as to if CF or SD cards were tested as the 7D utilizes a CF slot but can employ SD cards through adapters but then are limited to the capabilities of the adapter.
Hi – The 7D mark II takes both CF and SD cards
