Nikon D3400 DSLR Camera Body, Black {24.2MP}

Nikon D3400: 24MP entry DSLR with 1200-shot battery life

The D3400 carries a 24.2MP APS-C CMOS sensor processed through Expeed 4, delivering files with enough resolution to print large and crop aggressively. At 445 grams, it disappears into a bag and stays quiet enough for candid work. The optical pentamirror viewfinder covers 95% of the frame, you compose through glass, not a screen, which matters when you're tracking movement or working in bright light.

Shooting at 5 fps with a 100-frame JPEG buffer gives you real runway for youth sports and fast-moving subjects. ISO runs from 100 to 25600, and the Auto ISO implementation is practical, you set the floor shutter speed, the camera handles the rest. The 11-point AF system with a single cross-type center point is straightforward and reliable through the viewfinder; Live View AF is contrast-detect but noticeably quick for the class. Full manual, aperture-priority, and shutter-priority exposure modes are all present, with ±5 EV exposure compensation in 1/3-stop steps.

The EN-EL14a battery is rated for 1,200 shots per charge. That number changes how you travel with this camera, you stop counting shots and start shooting. SnapBridge Bluetooth keeps a background connection to your phone, trickling images over without requiring you to stop and initiate a transfer. The F-mount opens up decades of Nikkor glass, and with a 1.5x focal length multiplier, a 50mm f/1.8G becomes a 75mm equivalent portrait lens the moment you attach it.

Who It's For

Parents photographing school sports and recitals get the 5 fps burst rate and a 1,200-shot battery that doesn't die mid-event. Travel photographers working light appreciate a 445-gram body with F-mount access to compact primes and the SnapBridge connection for posting without pulling out a card reader. New shooters learning manual exposure find the Guide Mode and full PASM dial a practical on-ramp, with scene modes available when they want to hand the camera to someone else. Landscape photographers benefit from RAW capture at full 24MP resolution and the 12 white balance presets plus custom white balance for accurate color in shifting light.

FAQ

How long does the EN-EL14a battery actually last in real shooting?

Nikon rates it at 1,200 shots per charge (CIPA tested). In practice you'll see variation based on Live View usage, flash frequency, and how often you're reviewing images on the LCD-but the number holds up for optical viewfinder shooting without continuous SnapBridge transfers. Disable Bluetooth if battery life matters on a long day.

Can you use older Nikon lenses on the D3400?

F-mount lenses from the last 30 years will mount, but only recent glass (AF-S, AF-P, AF-I, type G, D) supports autofocus and full metering. Older manual-focus lenses work fine stopped down, but you lose phase-detect AF. The 1.5x crop factor turns a 50mm f/1.8G into a 75mm equivalent, which is useful for portraits.

Is the 11-point AF system reliable for action?

It's solid for youth sports and candid movement through the viewfinder. One cross-type AF point in the center, the rest are single-line. Continuous AF hunts occasionally in low light or complex scenes, but single-point AF is fast and locks confidently. Live View contrast-detect AF is surprisingly snappy-much faster than older Canon entry-level DSLRs.

What's the real-world advantage of SnapBridge over just transferring files manually?

SnapBridge runs in the background at low power and automatically sends 2MP versions of your shots to your phone without interrupting your shooting. Manual transfers require you to pause and initiate the process. The tradeoff is battery drain-enable it only if you're actively sharing or need GPS tagging from your phone.

Does the D3400 shoot 4K or RAW video?

No to both. Video maxes out at 1080p60 in H.264/MPEG-4, recorded to QuickTime files. You get manual exposure control for video (shutter and ISO, but not aperture), and continuous AF is solid with the AF-P kit lens. Mono audio only-the external mic socket from the D3300 was removed.

How does a pentamirror viewfinder compare to a pentaprism?

The D3400's pentamirror is bright and reliable but slightly dimmer than professional pentaprism finders. It covers 95% of the frame at 0.57x magnification. For composition and tracking moving subjects, it's glass-based and never lags like an electronic viewfinder-that matters in bright sun and for sports.

Will the D3400 keep up with mirrorless cameras for continuous shooting?

The D3400 shoots 5 fps with autofocus locked on the first frame, with a 100-frame JPEG buffer before slowdown. RAW is limited to 12 frames before the buffer fills. Mirrorless rivals like the Sony A5100 hit 6 fps with continuous autofocus, but the D3400's optical viewfinder gives you an uninterrupted real-time view-no blackout between frames.
