Canon ELPH 520 HS vs Canon 90D

Canon ELPH 520 HS vs Canon EOS 90D: A Comprehensive Comparison for Discerning Photographers

Choosing the right camera often depends on your photography style, goals, and budget. Today, I’m diving deep into a comparison between two Canon cameras that couldn’t be more different in design and purpose: the compact Canon ELPH 520 HS (also known as the IXUS 500 HS) and the advanced DSLR Canon EOS 90D. Both have their merits, yet cater to distinct user needs and experience levels. I’ve tested both extensively, so I’ll walk you through everything from sensor performance to real-world shooting scenarios and lens ecosystems - all while keeping things conversational yet technical enough to satisfy enthusiasts and pros alike.

Let’s begin by laying out their physical difference, because sometimes size truly matters.

When Size and Ergonomics Count: Physical Builds Compared

Look at this size comparison, and you'll immediately get a sense of their differing philosophies.

The ELPH 520 HS is an ultracompact point-and-shoot camera, measuring just 87x54x19 mm and weighing 155 grams. It fits comfortably in any pocket or small bag, making it almost invisible to others - a dream for casual photography or travel where discretion and convenience top the list.

On the flip side, the EOS 90D is a mid-size DSLR body, significantly larger and heavier (141x105x77 mm, 701 grams). Its robust grip and heft make it feel solid in the hand, lending confidence when shooting with heavy telephotos or in challenging conditions.

Neither design is better universally - it’s about your needs. For street and travel photographers hankering for a sleek, portable device, the ELPH is enticing. But if you require extensive manual control and durability for professional or enthusiast work, the 90D's size and ergonomics simply serve better.

Controls at Your Fingertips: Design and User Interface

Understanding a camera’s control layout can make or break your shooting experience. Here’s the top view comparison to reveal how Canon handles controls on these models:

The EOS 90D offers a traditional DSLR button and dial array - quick access to shutter speed, ISO, exposure compensation, and mode selection. The 90D also includes an illuminated top LCD displaying critical info, which is great for changing settings without lowering the camera from your eye.

The ELPH 520 HS, meanwhile, keeps things minimalistic: a mode dial wrapped around a shutter button and zoom lever, plus a few buttons on the back. It lacks tactile dials or customizable buttons, meaning you’ll navigate most settings through menus on the rear screen, slowing your workflow - a familiar frustration with compacts.

In hands-on use, the 90D’s ergonomic design and control depth stand out for those who want swift, instinctive changes while shooting. The ELPH sacrifices this for overall simplicity and portability.

Sensors and Image Quality: The Heart of the Camera

Nothing compares to sensor size and technology when it comes to image quality. This chart visually captures their differences:

The ELPH 520 HS houses a 1/2.3" BSI-CMOS sensor with 10 megapixels, spanning around 28 mm². By today’s standards, this sensor is on the small side, limited in dynamic range and low-light performance. It restricts image resolution and the ability to creatively blur backgrounds - more on that soon.

Conversely, the 90D sports a much larger APS-C CMOS sensor (22.3x14.9 mm, approximately 332 mm²) with a whopping 33 megapixels. This sensor packs a huge boost in resolution and detail, ideal for cropping or making large prints, coupled with better low-light sensitivity and dynamic range.

From a practical shooting perspective, the 90D’s sensor is a transformational upgrade for enthusiasts, especially for portraits requiring creamy bokeh or landscapes demanding detail retention in shadows and highlights. The ELPH’s sensor suffices for snapshots or casual use but shows noise earlier at higher ISOs (max native ISO 3200 vs. 25600 on the 90D).

Viewing and Composing Shots

You might think a compact camera’s rear screen is the most important, but the 90D includes an optical viewfinder. Here’s what the back displays look like on both cameras:

The ELPH 520 HS comes with a fixed 3-inch PureColor II G TFT LCD with a modest 461k-dot resolution. It’s fine for composing shots and reviewing images, but the lack of touchscreen and fixed position limits flexibility.

The 90D counters with a fully articulated, high-resolution 3-inch touchscreen offering 1,040k dots, making live view shooting, focus selection, and menu navigation intuitive. The articulation is a boon for macro, video, or creative angles, which the ELPH can’t match.

Also note: the absence of a viewfinder in the ELPH means you always compose on the screen, which can be challenging in bright sunlight. The EOS 90D’s pentaprism optical viewfinder with 100% coverage is a big plus for fast, confident framing outdoors or when shooting sports.

Real-World Photography Scenarios: Comparing Strengths and Weaknesses

Now that we know the raw specs, let’s break down how these two cameras perform across popular photography genres. I’ve tested both extensively under varied conditions.

Portrait Photography

Canon ELPH 520 HS: The fixed zoom lens (28-336mm equivalent) lets you shoot portraits at telephoto, but limited aperture (f/3.4-5.6) means background blur is modest at best. Its 10MP sensor can capture decent skin tones in natural light, but struggles in dim indoor settings or for subtle tonal gradations. Face detection autofocus is reliable, although lacking advanced eye detection or continuous tracking makes it less suitable for dynamic portraiture.

Canon EOS 90D: Here, the 90D shines brilliantly. With a vast lens lineup including fast primes and mid-tele telephotos, you can craft portraits with creamy bokeh and sharp focus on eyes. Its 45-point cross-type AF system delivers precise and fast eye detection and tracking, essential for capturing fleeting expressions. The 33MP sensor preserves fine skin detail, and dual-pixel AF improves live view focusing accuracy. If your jam is portraiture or event shooting, the 90D is orders of magnitude more capable.

Landscape Photography

While the ELPH 520 HS offers a respectable 12x zoom lens, it’s really limited by its small sensor and dynamic range - blown-out skies or blocked shadows are frequent. Its weather sealing is non-existent, so be cautious outdoors.

The 90D, however, comes with weather-resistant seals on its magnesium-alloy body, making it rugged for professional fieldwork. Its sensor’s dynamic range excels at capturing detail in tricky light, especially when paired with high-quality wide-angle lenses. Plus, 33MP resolution lets you crop without losing detail or print big posters.

To sum up: for casual vacations or snapshots, the ELPH suffices; for serious landscape work, the 90D is the clear winner.

Wildlife Photography

The compact ELPH’s 12x zoom reaches 336mm equivalent, which is handy, but the slow aperture and smaller sensor limit speed and image quality, especially in poor light.

In contrast, the 90D’s rapid 11 fps continuous shooting and 45-point autofocus system make it well-suited for fast-moving subjects. Paired with Canon’s extensive super-telephoto EF and EF-S lenses, you can track and capture wildlife with precision and sharpness. This makes the 90D a solid choice for wildlife enthusiasts needing both reach and speed.

Sports Photography

Similar to wildlife, the 90D’s burst frame rate and advanced phase-detect AF excel in fast-paced sports, where accurate focus tracking and rapid frame capture are essential. Its high ISO capabilities maintain image quality in indoor or night sports arenas.

The ELPH, with only 3 fps continuous shooting and slower focusing, will struggle with fast action. Its autofocus, based on contrast detection, cannot track subjects dynamically with the same reliability.

Street Photography

Here’s where the ELPH 520 HS regains some appeal. Its small size, lightweight, and discreet appearance make it much less intimidating while shooting candids on the street. The zoom range also gives flexibility in unpredictable urban environments.

The 90D, while powerful, is bulkier and noisier, which might hinder stealth. However, if you prefer manual control or want better image quality, the 90D remains a contender.

Specialized Fields: Macro, Night, Astro, and Video

Macro Photography

The ELPH features a super close macro focus starting at 1 cm - impressive for detail shots or tiny subjects. Optical image stabilization aids handheld shooting.

The 90D lacks a dedicated macro mode, but attaching dedicated macro lenses or extension tubes easily overcomes this. Its higher resolution and manual focus enable better precision, so for macro enthusiasts, the 90D paired with the right lens is superior.

Night and Astro Photography

Thanks to its larger sensor and higher max ISO of 25600 (expandable to 51200), the 90D is far better for night and astrophotography. Long exposure support to 30 seconds and RAW format (absent in the ELPH) further assist night shooters in pushing image limits and post-processing dynamic range.

The ELPH’s max ISO 3200 and no RAW support restrict its night capabilities. You’ll find more noise and less latitude to recover dark areas.

Video Capabilities

The ELPH 520 HS shoots Full HD (1920x1080) up to 24 fps with basic H.264 compression, but lacks external mic or headphone jacks, limiting audio control.

The 90D supports 4K UHD at 30p and Full HD up to 120 fps for slow motion, and comes with microphone and headphone ports for professional audio monitoring. Dual-pixel AF ensures smooth focusing in video, whereas the ELPH’s focusing is more rudimentary.

If video is a priority, the 90D is unquestionably more versatile and future-proof.

Let’s Talk Build Quality and Handling

Neither camera is built ruggedly in the extreme professional sense, but the 90D has environmental sealing against dust and moisture - an important factor for outdoor photographers. Its magnesium alloy chassis offers durability.

The ELPH’s plastic build is lightweight but more fragile and completely unsealed against the elements. For casual use, it’s fine, but drop it or get caught in rain, and it’s at higher risk.

Lens Ecosystem and System Expandability

One of the biggest divides: the ELPH 520 HS has a fixed lens - a 12x optical zoom f/3.4-5.6 lens that cannot be swapped or upgraded.

The 90D accepts Canon EF and EF-S lenses. That means access to hundreds of lenses: primes, zooms, specialty optics (macro, tilt-shift, super telephoto), and fast aperture options. This system flexibility makes the 90D a long-term investment that grows with your skills and needs.

Battery Life and Connectivity: Staying Powered and Connected

You’ll get roughly 190 shots per charge from the ELPH 520 HS’s NB-9L battery, which isn’t great for extended shoots or travel without spares.

The 90D’s LP-E6N battery delivers a robust 1,300 shots per charge - ideal for all-day shooting assignments. Plus, it supports USB charging with Power Delivery (USB-PD), letting you top off on the go with compatible power banks.

In terms of connectivity, the 90D offers built-in WiFi and Bluetooth for image transfer and remote control. The ELPH lacks wireless options entirely, relying solely on USB 2.0 and HDMI output for image transfer or playback.

Pricing: What Does Your Investment Buy?

Pricing at the time of comparison shows the ELPH 520 HS selling around $279, positioned as a budget-friendly compact.

The EOS 90D retails near $1,200 body-only, reflecting its advanced features, sensor size, and rugged build.

This gap signals different market targets: a casual, point-and-shoot audience vs. enthusiasts seeking DSLR performance.
