Nikon D7100 DSLR Camera

Description

The Nikon D7100 (released February 2013), a mid-range/prosumer DX-format DSLR that served as Nikon’s flagship APS-C camera at launch. It was designed for enthusiast and semi-professional photographers seeking high-resolution stills, advanced autofocus, and solid build quality in a weather-resistant body.

Key Highlights
• 24.1 MP DX sensor without optical low-pass filter (OLPF) for maximum sharpness and detail (sharper than most contemporaries but with potential moiré in fine patterns).
• Advanced 51-point autofocus with 15 cross-type sensors (center point works down to f/8 for teleconverter use).
• 6 fps continuous shooting (up to 7 fps in 1.3x crop mode).
• Dual SD card slots for backup, overflow, or separate RAW/JPEG recording.
• Weather-sealed magnesium-alloy construction (top and rear) for durability in tough conditions.
• Full HD video with stereo mic input and monitoring capabilities.
• Excellent ergonomics and customization, including dual control dials and U1/U2 user modes.

Sensor and Image Processor
• Sensor: 24.1 MP effective (24.71 MP total) DX-format CMOS (23.5 × 15.6 mm, 1.5x crop factor). No OLPF for enhanced resolution.
• Processor: EXPEED 3.
• ISO range: 100–6400 native (expandable to Hi-1: 12,800 and Hi-2: 25,600).
• Dynamic range: Strong at low ISOs with good color rendition; usable up to ISO 6400 in many conditions.
• File formats: JPEG, 12/14-bit RAW (NEF), RAW + JPEG.

Still Photography Performance
• Continuous shooting: 6 fps at full resolution; 7 fps in 1.3x crop mode (approx. 15 MP images).
• Autofocus: Multi-CAM 3500DX module with 51 points (15 cross-type), 3D Tracking, and AF fine-tune. Works in low light down to -2 EV.
• Metering: 2,016-pixel RGB 3D Color Matrix Metering II, with Center-weighted and Spot options.
• Shutter speed: 1/8000 s to 30 s, plus Bulb; flash sync at 1/250 s.
• Viewfinder: Pentaprism with ~100% coverage and 0.94x magnification.
• Other features: Active D-Lighting, Picture Controls, multiple exposure, interval timer, and 1.3x crop mode for extra “reach” with telephoto lenses.

Video Recording
• Max resolution: Full HD 1080p at 30/25/24 fps; 1080i at 60/50 fps (in 1.3x crop mode).
• Format: MOV (H.264) with built-in stereo microphone; external stereo mic jack and headphone jack for monitoring.
• Video features: Full-time AF (contrast-detect in Live View), manual exposure control, but limited compared to modern mirrorless (no 4K, slower AF in video).

Design and Ergonomics
• Body type: Mid-size SLR with magnesium-alloy top and rear panels; weather and dust resistant (not fully pro-level sealed).
• Dimensions: Approx. 136 × 107 × 76 mm (5.3 × 4.2 × 3.0 in).
• Weight: Approx. 675 g (body only) / 765 g with battery and card.
• LCD: 3.2-inch fixed TFT, 1,228,800 dots (high resolution for its time, no touchscreen or vari-angle).
• Controls: Intuitive with dual dials, dedicated buttons, joystick, and customizable functions. Includes Virtual Horizon indicator.
• Media: Dual SD/SDHC/SDXC slots (UHS-I compatible).
• Flash: Built-in pop-up i-TTL flash; hot shoe for external Speedlights with wireless commander mode.
• Connectivity: USB, HDMI, mic input, headphone jack; optional MB-D15 battery grip for extended shooting and vertical controls.

Power and Battery Life
• Battery: EN-EL15 Li-ion (CIPA rating: ~950 shots per charge).
• Optional: MB-D15 grip for additional battery or AA batteries; EH-5b AC adapter support.

The Nikon D7100 excels in delivering sharp, high-resolution images with fast and accurate autofocus, making it ideal for landscapes, wildlife, sports, and general enthusiast photography. Its removal of the OLPF provides extra detail, while the robust build and dual card slots appeal to serious users. It offers a great entry into Nikon’s extensive F-mount lens ecosystem, including compatibility with older AF lenses via the screw-drive motor.
Limitations (typical for a 2013 DSLR):

• Small buffer depth for long bursts (especially RAW).
• Fixed rear LCD with no articulation or touch.
• Basic video AF (contrast-detect only in Live View) and no 4K.
• No built-in Wi-Fi (SnapBridge or adapters needed for wireless transfer).
• High-ISO noise becomes noticeable above ISO 3200–6400 in some conditions.

Firmware updates reached version 1.05 (as of 2022), with minor improvements over the years. In 2026, the D7100 is long discontinued but remains popular on the used market (often very affordable) for photographers who prefer optical viewfinders and don’t need video-heavy features. It pairs well with lenses like the AF-S 18-105mm VR, 18-140mm VR, or primes for sharp results.
