The Canon 5D Mark III has long been one of Canon’s best camera offerings. It’s a workhorse of a DSLR in many videographer (and photographer’s) bags.

With this article, we’re going to cover the best CF card for Canon 5D Mark III.

One of the best tools in a videographer’s chest, be they a newbie or a veteran is the Canon EOS 5D Mark III.

Though Canon has since produced updated versions of the EOS 5D, the 5D Mark III is still one of the best and easiest to use DSLR cameras in the market. Especially when paired with a good CF card.

The Importance of a Good CF Card

Of primary importance, whether you’re a videographer or photographer, is always storing and safely retaining what you shoot. People who “go cheap” with their memory cards invariably get burned.

A CompactFlash card is a flash memory mass storage device that was designed to be used in portable electronic devices. Also known as a CF card, they were first manufactured by SanDisk in 1994.

The CF card remains a very popular way to extend the storage capacity of consumer devices, especially for digital cameras. As of 2017, Canon still makes their digital still cameras and their video cameras compatible with CF cards.

Let’s take a look at some of the best on the market.

CF Cards: What You Need To Know

CF cards use flash memory, which means they consume around 5 percent of the power required by other storage devices. They may be small but they are powerful and much more rugged then some other storage solutions.

They are also thick, which means they are less prone to bending or breaking (as well as getting lost).

When it comes to storage size, you can find CF cards in sizes ranging from 4GB to 512GB. The size of the CF card will usually determine the price.

CF cards are slightly similar to SD cards. Both storage devices are small and compact and they are usually used by just slotting them into your camera. But CF cards are slightly thicker and are available with a bit more storage size than SD cards.

As such, they are tougher and harder to break. If you film a lot under outdoor or rugged circumstances, or are prone to just absentmindedly putting a storage device in your pocket, a CF card might last you longer then and SD card.

That’s why a lot of people prefer to use the CF card (and the more expensive CF memory cards) even with cameras that come with dual card slots for both SD cards and CF cards.

Another advantage of a CF card over a SD card is CF cards are faster than SD cards. The write and read speed of even the slowest CF card in the market is miles faster than the best SD card in the market.
