The Canon 5D Mark IV has dual card slots. And each slot is unique, one slot takes an SD card and the other one is for a CF card. The dual card slots are very beneficial if you want to shoot in RAW and JPEG at the same time.
The camera automatically saves both files.
They can also be used for backup, which is very helpful if you are shooting important events such as weddings. You can use one SD/CF card for your main files and the other one for backup.
This way, if something goes wrong with one of your cards, you still have a copy of all your photos on the other.
That’s why the Canon 5D Mark IV is one of the top choices for professional photographers who need a reliable camera that won’t let them down.

Do I need 2 card slots?
The importance of dual memory card slots in a camera cannot be overstated. With two memory cards, photographers can have a backup of their images in case one card fails. They can also easily store more images than they could with just one card.
And, if one card becomes full, they can simply swap it out for the other card and continue shooting.
Dual memory card slots also give photographers the flexibility to choose the best file format for their workflow. For example, they can shoot RAW images to one card and JPEGs to the other.
Or, they can keep their images on one card and video on the other.
There are a few things to keep in mind when using dual memory card slots, though. First, make sure that both cards are of the same capacity.
Second, format both cards in the camera before use.
And third, if one card becomes full, be sure to remove it from the camera and replace it with the other card before continuing to shoot.
What cameras have dual card slots?
Like the Canon 5D Mark IV, the Canon 5D Mark III and 5DS both have dual card slots. They can also support 1 x SD card and 1 x CF card respectively.

Does the Canon 5D Mark III have dual card slots?
Yes, it has dual card slots. It accepts 1 SD Card and 1 CF Card. It is an excellent feature for people who like to have extra protection against accidental deletion or loss. With dual card slots, you can keep shooting without stopping to swap cards.
Is the Canon 5D Mark IV obsolete?
The Canon 5D Mark IV is not obsolete. However, it is discontinued, and Canon has reportedly stopped producing it, which will be the end of their 5D line.
Reports also said that Canon will focus solely on their EOS R mirrorless lineup and the Canon EOS R5 will be the mirrorless “5D”.
Fortunately, the Canon 5D Mark IV is still available from some retailers and third-party sellers, but supplies are limited and will eventually run out.
Is the Canon 5D Mark IV a professional camera?
It is a popular choice for professional photographers and videographers. The Canon 5D Mark IV is a high-end DSLR camera that was released in late 2016. It is the successor to the 5D Mark III and features many upgraded specs and features.
The 5D Mark IV has a 30.4 megapixel full-frame CMOS sensor, 4K video recording, and built-in Wi-Fi connectivity. The only thing I disliked about it is, that it doesn’t have an IBIS like my Canon 90D.
And if you were hoping for two SD card slots, there’s good news: You can still get that feature in the Canon 5D Mark IV.
The Canon 5D Mark IV is a camera designed for professionals that perform extremely well in most situations. It is not the cheapest full-frame DSLR on the market, but it is one of the best.
