Review Excerpt

Solid, ergonomic body design; Stunning, highly detailed photos, thanks to 24.1MP sensor upgrade and removal of optical low-pass filter; Cool 1.3x crop mode extends reach to nearly 2x the full-frame equivalent; Records Full 1080p HD video at up to 30fps with full-time AF; Many pro-level features packed into a consumer-friendly body at reasonable price.
Shallow buffer that hampers continuous burst shooting; AF slightly slower than average for its class; No real-time aperture control while in Movie mode (among other quirks); More noticeable moire patterns and aliasing artifacts (but only found when shooting fabrics with strong, distinct patterns).
Read our Nikon D7100 Review

Excellent value for the money; Professional-grade ergonomics; Incredibly good image quality for its class; Solid performance specs across the board; Loaded with features.
Kit lens may not be quite as sharp as previous kit lens from this line; Below average battery life; Somewhat confusing menu systems.
