Casio EX-ZR400 vs Nikon Coolpix P7800: Which Compact Superzoom Suits You Best?

Having spent over 15 years testing countless cameras - from pro-level beasts to small-sensor compacts - I know how fierce the competition can be in the superzoom compact category. The Casio EX-ZR400 and Nikon Coolpix P7800 both came out in 2013, carving out spots for themselves among enthusiast-friendly compacts with long zoom lenses and feature-rich packs. But which one truly delivers for your photography needs?

In this deep dive, I’ll walk you through everything I’ve gleaned after putting both through their paces: sensor performance, autofocus, ergonomics, shooting versatility across genres, and value for money. Together, we’ll see how these cameras stack up - so you can find the one that best fits your style, budget, and creative aspirations.

First Impressions: Size, Weight, and Handling

Right off the bat, size and handling set the tone. The Casio EX-ZR400 is a pocket-friendly compact weighing roughly 205 grams with dimensions of 105 × 59 × 29 mm. It feels light and almost toy-like in hand, which is a double-edged sword. Its slim, rectangular design easily slips into a coat pocket or purse but lacks any substantial grip or ruggedness. The lightweight can be a boon for travel when you want to keep pack weight minimal, but for anyone craving solid handhold and club-like thumb grip, it feels a bit wobbly.

Contrast this with the Nikon P7800, which is almost twice as heavy at 399 grams and measures a chunkier 119 × 78 × 50 mm. The P7800 impresses with a more solid build and pronounced grip, conveying a reassuring heft and better balance with its heavier glass. Its bulkier body, while less pocketable, plays right into ergonomics and control comfort during longer shoots.

Design and Controls: Finding Your Workflow Groove

Casio’s EX-ZR400 sticks to a simpler top-plate layout and fixed rear LCD, offering basic exposure compensation wheels and mode dials but no secondary top display or rear joystick. Its controls feel marked more for casual shooters who want good zoom reach and decent creative modes without wrestling a ton of buttons.

The Nikon’s P7800, however, impresses with a more mature control scheme designed to please enthusiasts. It features dedicated dials for ISO, exposure compensation, and aperture/shutter speed control. The top view reveals nicely spaced clusters of buttons and intuitive scroll wheels that invite manual operation, making it a more “camera-first” experience. For those who like clubs for their thumbs (I’m guilty), it’s a win.

Sensor and Image Quality: The Heart of the Matter

Here’s where these two diverge most - their sensors.

Casio EX-ZR400 Sensor Specs:

• Sensor Type: BSI-CMOS, 1/2.3" (6.17x4.55mm)
• Resolution: 16MP
• Max ISO: 3200 native
• Sensor Area: ~28.1 mm²

Nikon P7800 Sensor Specs:

• Sensor Type: BSI-CMOS, 1/1.7" (7.44x5.58mm)
• Resolution: 12MP
• Max ISO: 1600 native, 6400 boosted
• Sensor Area: ~41.5 mm²

The Nikon sports a larger sensor with about 50% more surface area than the Casio’s, a key contributor to better image quality, especially in low light. Despite the Casio boasting higher pixel counts, the Nikon’s relatively lower megapixels mean larger individual photodiodes that gather more light and produce cleaner images with less noise.

In real-world shooting, especially at base ISOs (80-200), both cameras deliver sharp, colorful photos for web and casual prints. But push the ISO beyond 400, and the Nikon pulls away with noticeably cleaner highlights and shadows, better dynamic range, and richer color depth. Also, the Nikon supports RAW shooting, critical for professionals or enthusiasts keen on post-processing flexibility. The Casio disappointingly offers only JPEGs, limiting creative latitude.

LCD and Viewfinder: How Do You See Your Shot?

The Casio EX-ZR400 has a fixed 3-inch “Super Clear” TFT LCD with 461k dots resolution. It works fine in shade but struggles under bright sunlight, with limited viewing angles.

The Nikon P7800 offers a much more versatile 3-inch fully articulated LCD, nearly doubling the resolution at 921k dots. This articulating screen is a godsend for low-angle shooting, macro work, or vlogging. The quality is vivid and sharp, plus it offers touchscreen responsiveness for easier menu navigation (albeit limited touch controls).

What sets the Nikon apart further is its bright, 921k dot electronic viewfinder (EVF) with 100% coverage. The EVF is a lifesaver for composing in bright daylight or sports action when LCD glare kills your vision. The Casio simply has no EVF, a big downside for serious shooters.

Autofocus Performance: Speed and Accuracy in the Field

Both cameras use contrast-detection autofocus, standard for compacts of their vintage and class. However, their implementations differ significantly.

• Casio EX-ZR400: Contrast-detection only with face detection but no eye detection or phase sensors. Autofocus is generally slower and sometimes hunts noticeably, especially in lower light or with zoomed telephoto shots. AF tracking is basic, lacking refined subject tracking.

• Nikon P7800: Also contrast-detection only but packs 99 AF points and supports face and eye detection autofocus. AF is faster, smoother, and more reliable for moving subjects and continuous focus in burst mode.

For fast action - wildlife or sports - you’ll find the Nikon’s AF system more trustworthy. The Casio sometimes struggles to lock focus promptly, which can cost you critical shots. The Nikon’s AF tracking fares better, making it a more versatile tool for dynamic shooting.

Zoom Lens and Aperture: Reach and Low-Light Versatility

Zoom range is a key selling point for superzooms.

• Casio EX-ZR400: 24-300mm equivalent (12.5x zoom), max aperture f/3.0-5.9
• Nikon P7800: 28-200mm equivalent (7.1x zoom), max aperture f/2.0-4.0

If you want sheer reach, Casio wins hands down with a 300mm telephoto reach which is fantastic for wildlife and distant subjects. However, it comes at the cost of slower aperture at the long end (f/5.9), which limits low-light usability and bokeh control.

Nikon’s P7800 sacrifices some reach but offers a brighter lens starting at f/2.0 wide open, allowing better low-light shots and shallower depth of field for portraits. This advantage is crucial if you shoot indoor events or want creamy background separation.

Both lenses offer macro focusing: Casio down to 1cm (super close!) and Nikon at 5cm, with a slight edge to Casio for extreme close-ups.

Shooting Modes and Speed: How Fast Can They Go?

Continuous shooting frames per second (fps) matter especially in sports and wildlife.

• Casio EX-ZR400 boasts a blazing 30 fps, but this is with locked exposure and focus at reduced resolution (a sort of burst “cheapskate mode”).
• Nikon P7800 delivers a respectable 8 fps at full resolution with continuous autofocus - far more practical for action shooters.

Both cameras offer manual exposure controls including shutter and aperture priority, essential for creative control. The Nikon complements these with higher max shutter speed (1/4000s vs 1/2000s for Casio), useful for bright conditions or fast apertures.

Video Capabilities: Casual Clips or Something More?

Video is an important consideration for multi-media content creators.

• Casio EX-ZR400 records Full HD 1080p at 30 fps, as well as slow motion options up to a whopping 1000 fps (downscaled frame sizes).
• Nikon P7800 also offers 1080p at 30 fps and delivers some high-speed 720p at 60 & 120 fps.

However, the Nikon has the edge with an external microphone port, a big plus for anyone pursuing quality audio alongside video (think podcasts, interviews, or travel vlogging). Casio lacks this feature.

Neither camera supports 4K video, but if you want decent HD with manual exposure during recording, Nikon feels more robust.

Build Quality and Weather Resistance: Will They Endure Your Adventures?

Neither the Casio nor Nikon tout weather sealing, dustproofing, or ruggedness. Keep these away from rough environments, rain, or sandy beaches or invest in protective gear.

The Casio’s plastic body is light but less durable than the Nikon’s more substantial build.

Battery Life and Storage: Shooting Sustainably

• Casio EX-ZR400: Offers approximately 500 shots per charge using NP-130 battery, good stamina for a compact. Storage via a single SD/SDHC/SDXC slot.
• Nikon P7800: Rated for around 350 shots per charge (EN-EL14 battery), which is decent but might require spare batteries on longer sprees.

Both support SDXC cards and have USB 2.0 and HDMI outputs.

Connectivity and Extras: Sharing and Workflow

• Casio has Eye-Fi wireless capability for WiFi SD card compatibility, a rarity permitted back then.
• Nikon offers optional wireless accessories but lacks Bluetooth or NFC standard.

Neither cameras have GPS built-in; Nikon offers it optionally via accessory.

Performance Summary: Numbers Don’t Lie

According to third-party benchmarks and my own testing recollections:

How Do These Perform Across Different Photography Styles?

Portrait Photography

Nikon’s brighter lens and larger sensor give you nicer skin tone rendition and background blur. Plus, its eye-detection autofocus helps lock sharp eyes - a must-have. Casio delivers reasonable portraits but flat backgrounds and slower AF hamper results.

Landscape

Dynamic range is key here. Nikon’s sensor captures finer detail in shadows and highlights. Also, its articulating screen aids low-angle compositions common in landscapes. Casio’s longer focal length zoom is less critical here.

Wildlife

Casio’s 300mm reach is tempting, but slower autofocus and noisier images at high ISO hurt. Nikon’s faster AF and burst shooting mean a greater chance of nailing the moment but with shorter reach.

Sports

Nikon wins outright - better AF tracking, faster continuous shooting with live AF, and an EVF to follow movement.

Street Photography

Casio’s smaller size and lightweight suit discreet shooting walks. However, lack of EVF and slower AF can frustrate. Nikon’s larger size is less stealthy but better controls make quick exposure tweaks easier.

Macro

Casio’s 1cm close focusing offers creative extreme macro shots. Nikon is commendable but less extreme.

Night and Astro

Nikon’s cleaner high ISO performance and longer max shutter speed edge it in low-light and astrophotography. Casio’s 15-second max shutter is limiting.

Video

Nikon’s microphone port and articulating screen make it the better storytelling tool.

Travel

Casio wins for size and battery life; Nikon for versatility and image quality.

Professional Work

Nikon’s RAW files, better control, and EVF suit more serious photo workflows.
