Canon SX730 HS vs. Samsung NX Mini: A Practical, Hands-On Comparison for Photography Enthusiasts

Choosing the right camera can feel like walking through a labyrinth, especially when comparing two models that serve quite different niches yet superficially seem to compete. The Canon PowerShot SX730 HS and the Samsung NX Mini both target casual and enthusiast shooters, but they do so in fundamentally different ways. After extensive hands-on testing and side-by-side comparisons, I’ll walk you through what makes each camera tick, their real-world strengths and weaknesses, and when one might serve your photographic ambitions better than the other.

Both cameras represent an interesting cross-section of the early-to-mid 2010s digital camera market, with the SX730 HS launching in 2017 as a refined compact superzoom and the NX Mini arriving a bit earlier, in 2014, as a notably slim, entry-level mirrorless system. Let’s dive in.

Getting Under the Hood: Size, Build, and Ergonomics

First impressions count, especially with cameras we carry all day or on trips. The Canon SX730 HS and Samsung NX Mini are both compact but approach the idea of portability differently.

The Canon SX730 HS is a chunky compact with dimensions of approximately 110 x 64 x 40 mm and weighing 300 grams. It’s built as a small-sensor superzoom with a fixed 40x optical zoom lens (24-960mm equivalent), which inevitably makes the camera thicker. This extra girth pays off with an extensive zoom range but can feel a bit unbalanced without club-sized hands to grip it.

By contrast, the Samsung NX Mini is a svelte 110 x 62 x 23 mm and weighs a mere 196 grams - about a third lighter than the Canon. That slim profile, a consequence of its rangefinder-style mirrorless body designed around a surprisingly large 1-inch sensor, makes it pocket-friendly and far easier to tuck away. However, that slimness comes with a compromise in grip comfort; you really have to “hold it right” to avoid feeling like you’re finessing a smartphone.

Now, looking at the control layouts:

The SX730 HS sports a conventional layout, with a prominent mode dial and dedicated buttons that are easy to reach even if your fingers instinctively clutch the zoom lever. Its tilting 3-inch screen helps compose shots from odd angles but does not support touch.

Samsung’s NX Mini opts for a minimalist, touch-focused interface with fewer dedicated physical controls. Its 3-inch articulating touchscreen offers a generous 461k-dot resolution and 180-degree tilt, giving it selfie-friendly potential despite lacking a front viewfinder or electronic eyepiece. That said, I would caution that extensive menu diving on the NX Mini’s touchscreen can be slower than using Canon’s physical dials and buttons, especially for shooting fast action.

Sensor, Image Quality, and Lens Ecosystem - The Core of Your Images

One of the most defining differences between these cameras lies in their sensors and how that impacts image quality.

Sensor Size and Resolution

• Canon SX730 HS: 1/2.3-inch BSI-CMOS sensor (6.17 x 4.55 mm, 20.3MP)
• Samsung NX Mini: 1-inch BSI-CMOS sensor (13.2 x 8.8 mm, 20.5MP)

Despite nearly identical megapixel counts, the physical sensor area of the NX Mini is over four times larger than that of Canon’s compact. That’s huge - literally and figuratively - since sensor size drives dynamic range, noise performance, and overall image quality.

If you’re familiar with sensor physics, the NX Mini’s bigger pixels gather more photons, translating to cleaner images with better color depth and better high-ISO capability. When I tested both side-by-side under varied lighting scenarios, the NX Mini consistently produced better-looking images at ISO100–800, showing richer tones and finer detail, whereas the SX730 HS images started showing noise and loss of shadow detail earlier.

Lens and Zoom

The Canon’s fixed 40x zoom lens (24-960mm equivalent) is a marvel of engineering given the form factor. It offers immense versatility for casual travel, wildlife spotting, or sports viewing without carrying extra glass. However, the max aperture range of f/3.3-6.9 means that at the longest end, you’ll struggle in low light, and bokeh separation is limited.

The Samsung NX Mini supports interchangeable lenses, though the NX-M mount has a very limited native lens selection (only 2 lenses available). For those lenses:

• The standard kit lens is a 9-27mm (24-72mm equivalent) f/3.5-5.6
• A faster 9-27mm f/3.5-5.6 lens is available, but options beyond that are rare
• With a 2.7x crop factor, lenses behave like traditional compact system lenses

While you can’t match the Canon’s zoom reach, the NX Mini’s ability to swap glass gives you sharper optics, wider apertures, and better creative control. This is particularly beneficial for portraits, macro, and low-light shooting.

LCD Screens and Viewfinder Options

Neither camera sports a dedicated electronic viewfinder, so live view framing comes down to the rear screen.

The SX730 HS has a decent but relatively low-resolution 3-inch LCD (922k dots) with a tilt mechanism (upward only), readable in daylight but not exceptional for critical focusing. The lack of touchscreen means navigating menus via buttons.

The NX Mini’s TFT LCD is lower resolution (461k dots) but supports touch control and tilts 180 degrees, ideal for selfies or low-angle shots. The touchscreen offers an elegant interface for shutter, focus, and playback. If you like touchscreen focus flexibility and selfie-mode, the NX Mini wins here.

Real-World Imaging: Sample Comparisons and Performance

Enough of specs - let’s get to what really matters: image output and shooting experience.

Portraits and Skin Tones

The NX Mini produces softer, natural skin tones with better color gradation thanks to its larger sensor and RAW support. It also offers more control in post since it shoots RAW files.

The Canon SX730 HS produces decent JPEGs out of the box but tends to over-sharpen and compress colors for speed, and the lack of RAW support limits editing latitude. Its background blur options are limited by the small sensor and slower lenses, though the 40x zoom allows framing flexibility.

Neither camera offers advanced eye tracking autofocus or animal-eye AF - features reserved for newer models. Still, the Canon has contrast-detection AF with face detection and tracking for reliable portraits. The NX Mini’s 21 focus points provide more selective focusing options.

Landscape and Dynamic Range

With vastly better dynamic range due to sensor size, the NX Mini captures more shadow and highlight detail in tricky lighting conditions - think sunrise, sunset, or high contrast scenes. Its RAW files are a gem for landscape photographers working on fine edits.

The Canon’s smaller sensor limits dynamic range and detail, and the heavy digital noise at higher ISOs stifles shadow recovery attempts.

Weather sealing is nonexistent on both, but the Canon’s more rugged body gives a slight edge in casual travel use.

Autofocus, Burst Shooting, and Speed

Silent, fast autofocus and continuous shooting rates matter for action, wildlife, and sports.

• Canon SX730 HS: 5.9 fps burst shooting, contrast-detection AF with face detection and tracking
• Samsung NX Mini: 6 fps burst shooting, 21 focus points, contrast-detection AF, no continuous tracking

In practice, both cameras deliver modest burst speeds suitable for casual sports or street photography but fall short of professional or enthusiast APS-C and full-frame cameras. The Canon’s face-tracking AF provides confidence for family snaps and casual subjects, but neither camera is tailored for fast-paced wildlife or sports.

Video Capabilities and Audio

For vloggers and casual video creators:

• Canon SX730 HS shoots Full HD 1080p at 60fps with 35 Mbps bitrate, without 4K or high-frame-rate options. No microphone input. Built-in optical image stabilization helps smooth handheld shots.
• Samsung NX Mini shoots 1080p at 30fps with H.264 encoding and supports an external microphone - rare for a camera in this class - though no headphone jack.

While neither camera targets videographers, the NX Mini’s microphone port and touchscreen interface edge out the Canon for casual video creators.

Battery Life and Storage Choices

Battery stamina can make or break a day’s shoot.

• Canon SX730 HS uses a custom Battery Pack with rated 250 shots per charge - somewhat modest but typical for compact superzooms with power-hungry zoom lenses.
• Samsung NX Mini uses the B740 Battery Pack with a generous CIPA rating of 650 shots per charge, which I found realistic in normal use.

In practice, the NX Mini twice outlasts the Canon between charges - a massive advantage for travel and day-long shoots.

Storage media differs too: the Canon uses regular SD/SDHC/SDXC cards, widely supported and cheaper, while the NX Mini uses microSD/microSDHC/microSDXC, compact but sometimes pricier and slower (be sure to pick a fast card to keep up).

Connectivity, Wireless, and Extras

Wireless features can boost workflow and sharing.

• Canon SX730 HS: Has built-in WiFi, Bluetooth, and NFC - offering easy pairing and remote control options.
• Samsung NX Mini: Limited to built-in WiFi, no Bluetooth or NFC.

The Canon’s Bluetooth low-energy pairing is especially handy for quick connections to smartphones for image transfer or remote shooting. The NX Mini’s touch interface for menu navigation is a plus, but connectivity options are more limited.
