I just made the jump from 6D to 5D MK IV, so now have the option of CF in addition to SD, and am just looking for some input on the card options.
1. How is everyone using the 2 slots? One for RAW, the other for JPEG, both for RAW simultaneously, one at a time for extra storage, etc.
2. Which format do you view as more reliable and your primary go-to card, SD or CF, and do you prefer SanDisk or LEXAR. Any thoughts on cheaper brands like Transcend? I don't mind paying more for better but would like to pay less if it's all the same.
3. What speed is necessary to shoot without any buffering on the 5D at full burst rate? Would the Extreme card at 120MB/s be sufficient, or should I opt for ExtremePro? Again, don't mind paying extra if it's necessary, but don't want to throw money out the window. Are there other reason besides speed to go with the ExtremePro, such as added reliability/longevity?
Thanks so much for any input.
