Canon 1D X vs Canon 5D Mark III Comparison

The Canon EOS-1D X is a high-level, professional camera aimed at individuals who make a career by taking images. Even though it was introduced in March 2012, it has rapidly established itself as one of the top cameras in its category and has been highly appreciated by photographers.

The Canon EOS 5D Mark III is one of the greatest full-frame DSLR cameras on the market. It’s a quick and strong performer that gives photographers the opportunity to attempt new forms of photography.

Both cameras have benefits, weaknesses, and places where one is better than the other, making a head-to-head comparison fun and engaging. I’d urge acting quickly to determine which camera is best for you, even though both are exciting.

Head To Head Comparison

Canon 1D X

The Canon EOS-1D X has a sleek, matte-black, yet robust magnesium alloy body that incorporates weather sealing to provide you an uncompromised shooting experience regardless of the weather, and I’m sure you’ve already set your expectations for this camera.

The EOS-1D X is sleek and robust, but it’s also comfortable to shoot with thanks to its polycarbonate and leatherette grip, which makes it easy to hold and steady. Canon rocks!

This unit’s controls are arranged and intuitive, so you can access them easily.

Top-center is a hot shoe, 3 specialized buttons are on the left, and an LCD screen is flanked by 4 buttons, and M-Fn button, and a release shutter button.

Due to the camera’s compactness, the back control arrangement is squeezed, but I don’t mind. Left of the viewfinder are the Menu and Info buttons, while the AF-ON button is on the right.

There are even more options on the right side and below the primary LCD panel to alter image playback and add speech. Below these button is a monochrome LCD that displays the card slot status and file type.

Let’s set aside the controls and discuss the viewfinder and LCD screen.

The EOS-1D X screen is 3.2 inches, has a 1,040k-dot resolution, and is fixed, yet it outputs great images to boost your user experience regardless of your viewing viewpoint.

The pentaprism viewfinder offers 0.76x magnification and 100% coverage. Once you start shooting through it, you’ll be immersed in the vista since you can catch anything nearby.

It has a mini-HDMI port, USB 2.0 port, twin CF card slots, and microphone port, but no Wi-Fi, therefore you’ll need a wireless transmitter to transfer files. Canon could have done better considering the price.

Dual DIGIC 5+ image processors greatly increase the EOS-1D X’s processing speed and noise handling from ISO 100-51,200, extendable to 204,800. Other features include a full-frame 18.1MP CMOS sensor, 61-point AF, and continuous shooting speeds of 12fps for RAW + JPEG and 14fps for JPEG.

This camera’s ability to manage noise caught my interest, and ISO 6400 produces the sharpest pictures. This pattern remains even at ISO 51,200, although noise becomes noticeable at this point. As predicted, blur starts to affect image quality at the highest native or expandable point.

Noise reduction might cause extra noise, but it can also improve photographs at high ISOs.

The EOS-1D X can capture 1080p at 24/25/30fps, 720p at 60/50fps, but not 4K. I think capturing 1080p films at 60fps would make the camera practically flawless.

Canon 5D Mark III

The Canon EOS 5D Mark III features an exquisite, black-painted, magnesium-alloy structure that feels smooth and strong on touch, but compared to the EOS-1D X, it lacks the same amount of protection, which means the EOS-1D X has a better overall build quality.

Either way, the grip is rough and wrapped with a rubber-like covering, which is helpful since the camera will sit solidly in your hands and be pleasant to shoot with.

On the top-left is a Mode dial with an On/Off switch, a hot shoe in the middle, and a monochrome Information LCD panel on the right. Above the screen are WB, AF-Drive, ISO, and a bulb that enables the panel’s lighting. On the grip are M-Fn and shutter release buttons.

On the rear-left, there are buttons near the screen, but there are additional buttons on the top and right-hand side that are easily accessible.

On top, there’s an optical, pentaprism viewfinder with 100% coverage and 0.71x magnification, and it allows you to focus on a specific target fast and efficiently, which is always pleasant. Since it covers such a broad area, you won’t miss a target throughout your shooting sessions.

The 3.2″ LCD screen lacks flexibility, so you can’t rotate it to shoot from different angles. However, because of its 1,040k-dot resolution and an optical gel within its glass cover, you’ll have a clear view even in broad sunlight.

As with its competitor, the EOS-1D X, the EOS 5D Mark III lacks built-in Wi-Fi, so you’ll need an extra wireless adaptor to transmit files.

The EOS 5D Mark III has a 22MP full-frame CMOS sensor, a 61-point AF system, a burst shooting speed of 6 fps, an ISO range of 100-25,600 that can be expanded to 50-102,800, and a DIGIC 5+ image processor that improves the camera’s processing speed and clarity.

This model reduces noise really well. Starting from ISO 800 – 3200, photos appear really excellent till ISO 25,600. At this level, the noise gets heavy and reduces quality, although it’s not as severe as between ISO 51,200 and 102,400. I’d advise avoiding the top sensitivity expansion settings unless necessary.

This is nothing to be shocked about, as no camera fails to retain great image quality at high sensitivity levels.

Before we close, I’d like to highlight that the EOS 5D Mark III captures 1080p movies at 30/25/24 fps, the same as the EOS-1D X, and while both create well-defined footage, filming at 60fps makes a difference. The score is tied.


I hope you’ve had an amusing read and are aware that both cameras are comparable, but with minor variances, which is expected given they’re not the same product.

Let’s compare the two cameras’ strengths before determining the winner.

In Portrait and Street photography, the 5D Mark III is marginally better because of its 22-megapixel sensor.

The 1D X’s quicker continuous shooting speed makes it ideal for sports photography, but the 5D Mark III is better for daily photography.

The EOS-1D X has a 100 percent higher Max ISO (51,200 vs 25,600), a faster continuous shooting rate (14fps vs 8), and greater low light ISO performance than the EOS 5D Mark III.

I’d choose the 5D Mark III since it performs similarly to the 1D X and is more cost-effective.
