Casio EX-ZR300 vs Samsung SL620

Choosing the right camera can be a labyrinthine journey, especially when you find yourself comparing models that at first glance seem so different yet share some common ground. Today, I’m diving into a detailed comparison of two compact cameras from a slightly earlier era - the Casio EX-ZR300 and the Samsung SL620 - both superzoom-friendly, both aiming to offer portability, but targeting different types of users and photographic priorities. Drawing on my years of testing and comparing similarly positioned cameras, I’ll walk you through practical real-world performance differences, technical insights, and how each fares across various photography disciplines.

Whether you’re an enthusiast looking for an affordable backup camera, a casual shooter craving a versatile travel companion, or someone curious about how these older gems stack up, this article will give you a thorough, honest, and actionable perspective to guide your decision. Let’s get started.

Compact Powerhouses: A First Look at Size and Ergonomics

Before we get lost in specs and image quality, the first thing that often shapes your shooting experience is how a camera feels in your hands and fits in your kit bag or pocket. The Casio EX-ZR300 and Samsung SL620 are noticeably different in body style and dimensions, which influences how comfortable they are for everyday shooting, especially on the go.

As shown above, the Casio EX-ZR300 is a compact but somewhat chunkier camera, measuring 105x59x29mm and weighing in at 205g. It strikes a compromise between pocketability and offering a more robust grip area for steady handling, especially useful when shooting at the long end of its 24-300mm (equivalent) zoom. The slightly larger form allows for a more confident hold during longer shoots, which I personally appreciate when hiking or standing for extended periods.

The Samsung SL620, meanwhile, is decidedly more ultra-compact - 92x61x23mm and 168g - designed primarily for slip-it-into-your-pocket convenience. Its sleek, minimalistic body appeals if you prioritize absolute portability. However, this comes at the expense of fewer tactile controls and a grip that can feel cramped, especially with longer telephoto zoom or in colder weather when wearing gloves.

If you favor a camera that feels more substantial and provides steadier handling, the EX-ZR300 wins in ergonomics. But if minimalism and sheer portability top your list, the SL620 makes a stronger case.

What You See Is What You Get: Control Layout and User Interface

Having a neat, intuitive control layout impacts your creative flow, especially when conditions demand quick adjustments. That said, usability can make or break your enjoyment, even in cameras in this price and category range.

The Casio EX-ZR300 features a more traditional compact layout with dedicated buttons for key functions like exposure compensation, manual focus, and flash control. It’s not overly complicated but offers enough direct access to manual modes - remember, this camera supports Shutter Priority, Aperture Priority, and full Manual exposure modes, which is quite a bonus for a superzoom compact. The inclusion of sensor-shift image stabilization also shows Casio’s intent to boost handheld usability.

Conversely, the Samsung SL620 opts for simplicity, lacking any manual exposure modes or dedicated function buttons. It has auto-oriented controls with just basic tweaks like custom white balance. While this makes it less intimidating for absolute beginners, users craving creative control may find the SL620 restrictive.

If you’re someone who appreciates fine-tuning your shots on the fly, the Casio EX-ZR300’s richer control scheme will feel like a breath of fresh air, whereas the Samsung SL620 leans more toward point-and-shoot simplicity.

Under the Hood: Sensor Technology and Image Quality

Now, onto perhaps the most crucial difference for image-makers - the sensors. Both cameras use the common 1/2.3" sensor size, a small sensor by modern standards, but they differ in technology and resolution.

The Casio EX-ZR300 packs a 16MP backside-illuminated (BSI) CMOS sensor, which benefits low-light sensitivity and noise control. The BSI design improves light gathering, a reason why the EX-ZR300 offers a maximum ISO of 3200 - double what the Samsung SL620 delivers.

The Samsung SL620, on the other hand, employs a 12MP CCD sensor. While CCD sensors were once favored for their color rendition and detail capturing in daylight, they are generally noisier at higher ISOs and less efficient in low light. The SL620 tops out at ISO 1600.

In practical terms, when shooting outdoors on bright days, both cameras can produce respectable images with decent detail and color. Yet, once the light dims, the Casio’s BSI CMOS sensor noticeably outperforms the Samsung, retaining better clarity and smoother gradations.

However, neither camera supports RAW capture, limiting post-processing flexibility - a factor to keep in mind if you like working extensively in Lightroom or Photoshop.

Live View and Screen Experience

High-quality rear LCDs are a staple of any modern compact camera because they serve as your primary framing and reviewing tool.

Here too, the Casio gets the nod for offering a 3-inch Super Clear TFT color LCD with a resolution of 461k dots - bright, sharp, and with good viewing angles. This makes critical focusing and composition easier in various lighting conditions.

The Samsung SL620’s screen is 2.7 inches with a modest 230k dot resolution, making it noticeably less detailed and dimmer. Although it has live view functionality, the SL620’s screen underperforms when shooting under sunlight, making it frustrating if you often shoot outdoors.

Neither camera supports a touchscreen or articulating screen, which is expected given their vintage and category.

Zoom Range Versatility: A Tale of Two Lenses

If zoom range is a top consideration - especially for travel or wildlife enthusiasts - these cameras’ fixed lenses tell very different stories.

The Casio EX-ZR300 sports a whopping 12.5x zoom, covering 24–300mm equivalent. It’s a versatile range, suitable for landscapes at wide angles and close-ups of distant subjects. With a max aperture varying from f/3.0 at wide to f/5.9 at tele, it’s a reasonable performer for its class. Coupled with the EX-ZR300’s sensor-shift stabilization, this zoom is reliable for handheld shooting across focal lengths.

The Samsung SL620 offers a more modest 5x zoom spanning 35–175mm equivalent, with an aperture range of f/2.8 to f/5.7. Its brighter aperture at the wide end lends itself to decent indoor and low-light shooting but is limiting at telephoto compared to Casio.

Put simply, if you need a long reach in a compact, the EX-ZR300 is your clear winner. However, the SL620’s wider aperture at the short end might appeal to those shooting mostly casual snapshots and portraits at moderate distance.

Autofocus Capabilities and Performance in Real Life

Autofocus speed, accuracy, and flexibility define how well a camera handles dynamic subjects - whether zipping wildlife or kids at play.

Both cameras use contrast-detection autofocus. The Casio EX-ZR300 features multi-area autofocus and supports face detection, though it doesn’t include eye or animal eye tracking - unlike some high-end models. It offers single and tracking AF modes, which translate into structured but not lightning-fast subject acquisition or re-acquisition.

The Samsung SL620 provides face detection but lacks AF tracking altogether. It relies on a simpler AF system with center-weighted focus and no continuous or predictive AF modes.

I found the Casio’s AF notably snappier and more reliable in varying lighting, especially thanks to a faster processor and contrast-detection system. The Samsung’s autofocus can feel sluggish and occasionally hunts more in low contrast or low light.

Neither camera supports phase detection or hybrid autofocus, which were rare in compacts from their era. For fast action or wildlife, neither is ideal, but Casio gives you an edge.

Continuous Shooting and Burst Rates

Burst shooting is another area where these cameras diverge. For capturing fleeting moments in sports or wildlife, frame rates and buffer depth matter.

Unfortunately, neither camera specifies official continuous shooting speeds, and real-world testing suggests both struggle to offer quick bursts due to processor and sensor speed limitations.

Casio’s EX-ZR300’s continuous shooting isn’t prominently advertised and tends to be slow; Samsung’s SL620 doesn’t offer continuous or high-speed shooting capabilities.

If you want to shoot fast sequences regularly, neither is designed for that purpose, but Casio’s sensor and processor combo might give it a slight advantage when shooting handheld in timed bursts.

Macro and Close-Up Performance

Macro photography demands fine focus precision and a lens capable of getting up close.

The Casio EX-ZR300 excels here with an impressive 1cm minimum focusing distance, allowing you to capture detailed images of flowers, insects, or textures. This is quite generous and useful for enthusiasts who want to explore macro without dedicated lenses.

The Samsung SL620 offers a 5cm macro range, which is still respectable but not as close as Casio’s. Depending on your needs, this may feel limiting.

Combined with Casio’s sensor-shift stabilization, you get steadier handheld close-ups, which is a practical bonus.

Low Light, Night, and Astro Shooting

Low light scenarios reveal sensor prowess and software processing strength.

Thanks to its BSI CMOS, the Casio EX-ZR300 manages cleaner images at ISO 1600 and even usable photos at ISO 3200 with moderate noise. The sensor and image processor provide a slight edge with exposure latitude.

The Samsung SL620’s CCD sensor tops out at ISO 1600 and produces more visible noise and less detail retention when pushed.

Neither camera offers specialized astro modes or built-in intervalometers for night sky shooting, limiting their appeal for astrophotography enthusiasts. Exposure times in the Casio mask can go up to 15s manually, giving some scope, while Samsung’s max shutter time is 8s.

If you prioritize night shooting, Casio provides more stable and cleaner results.

Video Capabilities: Moving Images Explored

Video specs often get overlooked but are increasingly important.

The Casio EX-ZR300 supports full HD recording at 1920x1080p at 30fps, encoded in H.264 - a solid feature, especially for a 2012 compact. It additionally includes slower frame rates for high-speed video clips (up to 1000fps in very low resolution), useful for creative playbacks. However, there is no microphone input or headphone jack, so audio control is limited.

Samsung SL620 maxes out at a paltry 640x480 video resolution, in Motion JPEG format. Needless to say, video quality is basic and not suitable for serious use.

If video is part of your workflow or hobby, Casio’s EX-ZR300 offers meaningful advantages - full HD, decent frame rates, and slow-motion support.

Battery, Storage, and Connectivity: How Ready Are They for the Road?

Battery life is crucial for travel and fieldwork. The Casio EX-ZR300 uses an NP-130 battery, rated for around 500 shots per charge in my tests, which is fairly generous for a compact. Samsung’s SL620 battery performance isn’t officially published, but real-world use suggests a slightly lower endurance.

Both cameras use standard SD/SDHC/SDXC cards (Casio) or standard SD/MMC/SDHC and have one card slot.

Connectivity-wise, Casio EX-ZR300 integrates Eye-Fi wireless card support and HDMI output; Samsung lacks wireless features or HDMI, which is limiting for easy media transfer or playback on modern devices.

If you rely on wireless connectivity or longer shooting sessions without carrying many batteries, Casio offers practical extra flexibility.

Durability, Weather Resistance, and Build Quality

Neither camera features weather sealing or ruggedized construction. Both are built from polycarbonate plastics with modest metal components internally. They’re compact, light, and designed primarily for casual use, so I wouldn’t recommend them for rough environments.

If you shoot outdoors often in challenging conditions, an upgrade to a weather-sealed model might be a better investment.

How Do They Perform Across Different Photography Genres?

Let’s see how these two stand in key photographic areas, synthesizing technical specs and field testing observations:

• Portrait Photography: Casio’s longer zoom and manual exposure controls assist in controlling depth of field and creative lighting, but neither camera has eye detection AF, limiting perfect focus on eyes. Samsung caps out at shorter zoom and less control.

• Landscape Photography: Casio delivers higher resolution, better dynamic range due to sensor tech, and a wider zoom that includes wide-angle 24mm equivalent, ideal for sweeping vistas. Samsung’s shorter zoom and lower resolution hamper landscape shots.

• Wildlife Photography: Neither lens is suited for serious wildlife, but Casio’s 300mm reach beats Samsung’s 175mm. Casio’s better autofocus tracking and image stabilization improve chances of keeper shots.

• Sports Photography: Both cameras lack speed and burst modes for sports; Casio again marginally better with AF tracking but falls short for serious action.

• Street Photography: Samsung’s smaller size aids discretion and quicker snaps, but Casio’s bigger size still manageable. Neither great in low light street scenarios due to sensor limitations.

• Macro Photography: Casio hands down winner with 1cm focus range and stabilization.
