Nikon Z7 vs Samsung SL720: An Expert Hands-On Comparison for Every Photography Enthusiast

Choosing a camera that fits your photography style, budget, and workflow can feel overwhelming - especially when the gap between models is as vast as that between Nikon’s top-tier Z7 and the modest Samsung SL720 ultracompact. Having tested thousands of cameras over 15 years, I’m here to break it down with clarity and fairness, focusing on what really matters in real-world use across all major photography genres.

By the end of this detailed comparison, you’ll understand not only which camera suits you best, but why - backed by hands-on insight, technical expertise, and practical advice. Let’s dive in.

What’s on the Table? A Quick Spec Overview

Before getting deep, here’s an at-a-glance look at our contenders:

With a quick glance, the Nikon Z7 is clearly a high-end professional mirrorless camera, while the Samsung SL720 is a compact, affordable daily shooter. That doesn’t mean the Samsung is worthless - it actually shines as a simple “grab and go” camera and introduces a useful comparison around evolving technology.

Build Quality & Handling: Clubs for Thumbs vs Pocket Buddies

One of the first things you notice when picking up these cameras is the significant difference in size, weight, and handling.

The Nikon Z7 is a substantial camera at 675g and measures roughly a thick 134x101x68 mm. It’s designed with a deep, grippy handhold and solid magnesium alloy chassis. The camera feels rock-solid, weather-sealed against dust and moisture - making it reliable in challenging conditions. Controls are plentiful and logically placed, from customizable buttons to the responsive tilting touchscreen LCD and a bright, high-resolution electronic viewfinder that almost feels like looking through an optical one.

Contrast this with the Samsung SL720, which weighs just 168g and fits comfortably in any pocket. Its body is plastic, with a fixed lens and minimal controls - typical of ultracompact cameras. The screen is small and low-res (2.7” at 230k dots), and there’s no viewfinder, so composing shots outdoors in bright light requires some patience.

For a photographer prioritizing long shoots, many buttons to assign, and a camera that feels tailor-made for your hands, the Z7 is king. For someone prioritizing ultra-portability, ease of carry, and simplicity, the SL720’s small footprint is a clear win.

Sensor Technology and Image Quality: Feast or Famine?

Here’s where the two cameras truly part ways. The Z7 features a 46-megapixel Backside Illuminated (BSI) CMOS full-frame sensor measuring 35.9 x 23.9 mm, producing brilliantly detailed images at up to 8256 x 5504 resolution without an optical low-pass (anti-aliasing) filter. This sensor, paired with Nikon’s Expeed 6 processor, delivers an expansive dynamic range (~14.6 stops per DxOMark testing), exquisite color depth (26.3 bits), and solid performance in low light (native ISO 64-25600, boosted to 102400).

In contrast, the Samsung SL720 sports a tiny 1/2.3” 12MP CCD sensor, with a resolution of 4000 x 3000 pixels and a much smaller sensor area of just 27.7 mm². This limited sensor size restricts dynamic range and low-light performance and generally means images are noisier, lack depth, and hold less detail compared to the full-frame powerhouse.

I've experimented with both cameras extensively. The Z7 produces files worthy of large prints, demanding editorial work, and the most discerning eye. Skin tones and subtle color gradations come through with natural smoothness - perfect for portraits and landscape work.

The SL720 delivers decent images in good daylight but struggles as soon as you dial up the ISO or shoot shadow-heavy scenes. Its CCD sensor excels at handling direct sunlight but can't compete with the depth and definition from modern BSI-CMOS full-frame tech.

Autofocus: Lightning vs Leisurely

Autofocus performance can make or break a shoot, whether it’s catching a fleeting moment or locking eyes with precision for portraits.

The Nikon Z7 boasts 493 hybrid autofocus points using a mix of phase-detection and contrast detection. The inclusion of sophisticated face and eye detection, as well as animal eye AF, not only aids portrait and wildlife photographers but makes tracking moving subjects smoother. I’ve tested the Z7 extensively for sports, wildlife, and street photography workflows: its AF is fast, confident, and rarely misses.

The Samsung SL720, being a compact, relies on contrast detection alone without face or eye detection. It offers single-shot AF with no continuous tracking, and it can be a bit sluggish and “hunt” in low contrast or mixed lighting.

For demanding action photography, or close portraiture where pinpoint eye focus is critical, the Z7 clearly outperforms. For casual snapshots and travel vacation photos where AF speed isn’t make-or-break, the SL720’s system is passable.

Usability, Displays, and Controls: Touch & Tilt vs Fixed & Minimal

The Z7 sports a bright 3.2” touchscreen LCD with 2.1 million dots resolution. It tilts, making it extremely versatile for low-angle compositions or overhead shooting. Touch controls make menu navigation and AF point placement intuitive, especially helpful if you’re used to smartphones.

The rear interface is well laid out - buttons are logically grouped and illuminated for dim conditions (though you’ll have to squint a bit; there are no backlit buttons). The camera also features a 3.69 million-dot electronic viewfinder with 100% coverage, a massive advantage in bright environments, providing stable, high-res framing.

Compare that with the Samsung SL720’s 2.7” fixed display at only 230k dots. It does the job but feels a bit dated and tiny by today’s standards - no touch, no tilt, and no EVF means composing can be a challenge in certain lighting.

If you love an ergonomic, flexible control scheme and bright displays, the Z7 feels like a modern digital tool designed for workflow efficiency, whereas the SL720 is very much a simple point-and-shoot experience.

Picture Styles and Real-World Results: Sample Gallery

I always recommend looking at actual images to understand camera character. Below is a gallery showcasing images from both cameras, covering portraits, landscapes, street shots, and macro.
