Canon 1D Mark IV vs Canon 5DS: A Hands-On Comparison for Serious Photographers

As a photographer who’s spent well over a decade testing and working extensively with Canon’s DSLR lineup, I’ve seen countless evolutions in sensor technology, autofocus performance, and ergonomics. When the Canon EOS-1D Mark IV was announced back in 2010, it represented a powerhouse professional DSLR designed primarily with fast-paced action photographers in mind. Five years later, Canon introduced the 5DS - a camera that shifted the focus towards ultra-high-resolution imaging in a more compact form factor.

In this detailed comparison, I’ll bring my firsthand experience with thousands of shutter actuations, real-world shooting scenarios, and technical evaluations to help you understand how these two bodies stack up in 2024. Whether you’re hunting for a pro-grade workhorse or a studio-level pixel monster, this side-by-side analysis goes beyond specs, diving into actual performance, usability, and value - so you can make the best choice for your photography pursuits.

First Look: Size, Weight, and Handling

Let’s start with something tactile but fundamental: the feel of the camera in your hands. The Canon 1D Mark IV is a large, rugged pro DSLR - part of Canon’s flagship 1D series - designed explicitly for strenuous fieldwork and tough environments. It weighs a hefty 1230 grams and measures 156 x 157 x 80 mm, sporting a solid magnesium alloy body with extensive weather sealing. This is a camera meant to be grasped firmly, even with thick gloves, and to charge through dust, moisture, and freezing conditions.

In contrast, the 5DS is a mid-size DSLR that drops some bulk for improved portability, weighing around 930 grams and measuring 152 x 116 x 76 mm. It maintains a weather-sealed body but not as bulletproof as the 1D Mark IV. For many photographers who work on the move - travel shooters, street photographers, even studio artists who want a lighter rig - this size difference is significant.

I’ve personally carried both on extended shoots. The 1D Mark IV feels like a tank - a reliable co-pilot on wildlife safaris or sports arenas where you want that rock-solid grip and endurance. The 5DS, while not exactly featherlight, balances sturdiness with manageable weight. For daily travel or street work, I often prefer its smaller footprint without sacrificing control.

Ergonomically, both cameras feature thoughtfully placed controls and traditional Canon layouts, but the 1D Mark IV’s extensive customizable buttons and top display give it an edge in demanding pro workflows. We’ll dive deeper into that shortly.

Design Details: Control Layout and User Interface

A quick glance at the top of both cameras highlights interesting design choices.

The 1D Mark IV’s top panel has a wealth of physical controls - dedicated dials for ISO, metering mode, drive mode, and more. This enables lightning-fast adjustments without needing to dive into menus, a critical advantage during high-pressure, fast-action shooting like sports or wildlife events.

The 5DS simplifies the top controls while maintaining essential dials and buttons. It swaps some dedicated controls for more streamlined operation, emphasizing live view autofocus capabilities and a clean interface for studio and landscape shooters.

Both cameras rely heavily on Canon’s traditional menu system, which is extensive but well organized. Neither has touchscreen functionality, so tactile button feedback is key.

Sensor Technology and Image Quality Deep Dive

Now, onto the heart of the beast: the sensor. The 1D Mark IV houses a 16MP APS-H sized CMOS sensor (27.9 x 18.6 mm) with an antialiasing filter in place. On the other hand, the 5DS brings a massive 51MP full-frame CMOS sensor (36 x 24 mm), also with an antialiasing filter.

What does this mean practically?

• The 5DS sensor offers over three times the resolution of the 1D Mark IV, delivering files up to 8688 x 5792 pixels. This level of detail is outstanding for large prints, high-end commercial work, and extensive cropping flexibility.
• The 1D Mark IV’s APS-H sensor, smaller than full frame but larger than APS-C, offers high-speed processing advantages and is tuned for superior high ISO performance relative to its era.
• According to DXO Mark scores, the 5DS boasts higher overall image quality: color depth (24.7 bits vs. 22.8 bits), dynamic range (12.4 stops vs 12 stops), and particularly improved low-light ISO performance (ISO 2381 vs ISO 1320).

In my experience shooting landscapes and studio portraits, the 5DS’s higher resolution yields stunningly crisp, detailed images with excellent color fidelity and broad tonal latitude - ideal for photographers who prioritize image quality above all else.

Conversely, the 1D Mark IV’s sensor favors speed and responsiveness. The slightly lower megapixel count paired with the crop factor (1.3x) means the effective field of view differs, which for telephoto-heavy genres like wildlife and sports can be advantageous.

Autofocus Systems: Speed, Precision, and Tracking

Autofocus is where these cameras truly shine in their respective niches.

• Canon 1D Mark IV: 45 focus points (all cross-type unknown count), no animal or eye detection AF support. Phasedetection autofocus with contrast detection in live view. AF continuous and selective AF available but no advanced tracking algorithms.
• Canon 5DS: 61 focus points with 41 cross-type sensors, supports face detection, eye detection, and select continuous autofocus with tracking modes.

From my extensive testing:

• The 1D Mark IV’s autofocus system was cutting-edge in 2010, designed for rapid acquisition and stable AF under challenging light and fast movement scenarios. It locks focus quickly in daylight and excels at predicting movement across the frame, which made it a favorite for sports shooters.
• The 5DS benefits from hardware and software improvements in AF algorithms, offering more precise subject tracking and wider focus coverage, which is especially beneficial in studio portraits and landscape compositions. However, its slower 5fps burst rate slightly limits its action-shooting potential.

While neither model supports animal eye autofocus (which is becoming common in newer cameras), the 1D Mark IV’s AF responsiveness still gives it the edge for wildlife and sports where split-second timing matters.

Burst Rates and Buffer: Speed vs Resolution Trade-offs

Shooting fast bursts is vital for certain genres like sports and wildlife.

• The 1D Mark IV manages 10 fps continuous shooting - still fast by today’s standards.
• The 5DS tops out at 5 fps, half as fast.

Given the 5DS’s massive 51MP files, this slower speed is understandable. Buffer capacity is generally good on both, with dual card slots supporting CF and SD (type varies), but the 1D Mark IV handles data flow more efficiently for burst shooting.

If you shoot tennis matches, soccer games, or fast-moving wildlife, the 1D Mark IV delivers more decisive speed and responsiveness.

Build Quality and Weather Sealing

Both cameras are weather-sealed, but the 1D Mark IV offers more robust environmental durability built to withstand harsh conditions - rain, dust, freezing temps - essential for professional photojournalists, wildlife photographers, and outdoor sports shooters.

The 5DS, while sealed against dust and moisture, is not designed for extreme conditions as extensively. Its lighter weight and smaller body reflect its more studio- and landscape-focused design philosophy.

LCD Screens and Viewfinders: Composing with Confidence

The 1D Mark IV uses a fixed 3-inch LCD with 920k-dot resolution, whereas the 5DS slightly upgrades this to a 3.2-inch, 1040k-dot fixed LCD. Both do not have touchscreens.

The optical viewfinders on both cameras cover 100% of the frame but differ in magnification: 0.76x on the 1D Mark IV, 0.71x on the 5DS. The 1D Mark IV thus provides a slightly brighter and larger viewfinder experience, crucial for quick, precise framing in the field.

During my wildlife outings, I found the 1D Mark IV’s viewfinder essential for following erratic subjects. The 5DS shines more in deliberate, composed solo shooting where image review on the higher-res LCD is appreciated.

Lens Ecosystem and Compatibility

Both cameras use the Canon EF lens mount, compatible with the same extensive ecosystem of over 250 lenses - a massive advantage for versatility.

• The 1D Mark IV’s 1.3x crop factor means lenses behave slightly differently than on the full-frame 5DS - telephotos get a tighter field of view, helpful but important to account for.
• The 5DS’s full-frame sensor effectively uses the entire image circle, benefiting wide-angle lenses and providing a natural “full frame” feel.

Since Canon’s EF mount is widely supported, both bodies can grow their capabilities across macro, telephoto, portrait, and specialized optics without limitations.

Battery Life and Storage Options

Battery endurance is a significant factor for outdoor or travel shooting.

• The 1D Mark IV’s LP-E4 battery can yield around 1500 shots per charge - remarkably robust.
• The 5DS with the LP-E6 battery averages about 700 shots - less than half.

If you often shoot all day without access to recharging, the 1D Mark IV’s battery longevity is a decisive advantage.

Both cameras offer dual card slots, though the 1D Mark IV uses Compact Flash (Type I/II) plus SD/SDHC, while the 5DS supports CF and SD/SDHC/SDXC (UHS-I). The 5DS’s inclusion of modern SDXC compatibility with faster UHS-I cards offers easier access to affordable, high-capacity cards.

Connectivity and Workflow Integration

• The 1D Mark IV includes Eye-Fi card compatibility for wireless in-camera image transfer (an innovative, though limited, Wi-Fi solution for the era).
• The 5DS lacks built-in wireless options, relying on USB 3.0 (5 Gbps) and HDMI outputs for faster tethered transfers and live view displays.

Based on professional experience, tethering the 5DS in studio environments greatly improves workflow, and rapid USB 3.0 speeds can make a big difference for handling large RAW files. The 1D Mark IV’s older USB 2.0 interface is slower but still reliable for field backups.

Real-World Photography Scenarios

To put all the specs into perspective, here are my observations from extensive shooting across various photography disciplines:

Portrait Photography

The 5DS’s megapixel advantage creates images with absurd fine detail, excellent color accuracy, and creamy natural skin tones when paired with prime portrait lenses. The camera’s 61-point autofocus aids in precise eye detection and face tracking, making studio and outdoor portraits a true joy.

The 1D Mark IV performs well but can’t compete in sheer resolution. Yet, focus speed keeps pace for event and candid portraits where spontaneity matters. The 5DS edges ahead for editorial and commercial portraiture demanding maximum detail.

Landscape Photography

I am a landscape photographer’s advocate for high dynamic range and resolution - the 5DS ticks both boxes with a full-frame sensor providing wide tonal gamut and tremendous detail. Weather sealing is good for decent outdoor protection.

The 1D Mark IV’s crop sensor limits field of view compared to full-frame, but its ruggedness is superior for challenging environments. For landscape photographers prioritizing portability and ultimate image quality, the 5DS is typically preferable.

Wildlife and Sports

Here, the 1D Mark IV’s speed and robust autofocus system deliver tangible benefits. Ten frames per second with 45 AF points allows capturing decisive moments of animal behavior or game action like a pro. The crop factor gives extra reach on telephoto lenses, critical for distant fast subjects.

The 5DS’s slower burst rate and reliance on tracking AF make it less ideal for fast subjects - I found it better suited to landscape or controlled portrait sessions than unpredictable wildlife sequences.

Street Photography and Travel

Weight and discretion matter for street shooters. The 5DS is smaller and lighter, easier to carry all day, and produces ultra-detailed captures at moderate shutter speeds.

The 1D Mark IV, while durable, can be bulky and draws more attention, but has the battery endurance for long excursions. I recommend the 5DS here for casual street and travel photographers who prioritize image detail over ruggedness.

Macro Photography

Both cameras lack built-in image stabilization, relying on lenses and tripods, but the 5DS’s resolution facilitates more creative cropping and detailed close-ups.

The 1D Mark IV’s more sensitive AF can aid quick focus in macro work, but resolution limits ultimate detail. The 5DS is generally better suited for controlled macro photography.

Night and Astrophotography

High ISO performance and low noise are critical here. The 5DS provides improved clean ISO up to 6400 native, better than the 1D Mark IV’s 12800 max native but noisier output.

In my tests, the 5DS produced cleaner stars and skies at long exposures, thanks to modern sensor improvements and dual DIGIC 6 processors. The 1D Mark IV’s older sensor contributes more noise, but superior weather sealing still makes it viable for harsh nocturnal conditions.

Video Capabilities

Interestingly, both cameras offer similar Full HD video resolution (1080p max at 30fps), but neither supports 4K or advanced video features.

The 1D Mark IV includes a microphone input; the 5DS continues that trend, but neither has headphone monitoring or advanced stabilization.

Both are adequate for casual videography but do not cater to serious filmmakers.
