Nikon's semi-pro DX DSLR without an anti-aliasing filter, delivering exceptional sharpness.
The Nikon D7100 was launched in February 2013 as Nikon's enthusiast DX DSLR, replacing the D7000. Its standout feature was the 24.1MP APS-C CMOS sensor built without an optical low-pass filter (OLPF), delivering noticeably sharper resolving power than filtered sensors at the same resolution. Nikon's official press release cited the filter removal as a deliberate design decision for the high-resolution sensor. The D7100 targeted serious amateurs and semi-professionals wanting advanced controls and strong image quality without full-frame cost or bulk, and became one of the most highly regarded DX DSLRs of its generation.
The 51-point Multi-CAM 3500DX II AF system provides 15 cross-type points — the same AF architecture as the professional D300s. Burst shooting runs at 6fps in standard DX mode, increasing to 7fps in a 1.3x crop mode. The RAW buffer in 14-bit lossless format is approximately 6 frames before the camera slows, a limitation the D7200 specifically addressed in 2015. Video covers 1080p at up to 30fps, suitable for documentary and casual interview work. Dual SD card slots provide backup and overflow configurations. The weather-sealed magnesium alloy body was described by Nikon as meeting the moisture and dust resistance of the D300s.
In practice the D7100's resolving power is exceptional for a DX body. The absence of an OLPF allows the sensor to capture finer texture and detail, and the 24.1MP pixel count provides useful crop latitude for wildlife and telephoto work. The 51-point AF with 15 cross-type points is fast and reliable for portraiture, events, and moderate action. The burst buffer limitation is the most significant operational constraint: after approximately 6 RAW frames the camera reduces to near-single-shot pacing, making extended sequences impractical. For landscape, documentary, and controlled shooting the D7100 delivers consistently strong results.
On the used market the D7100 is good value for DX shooters who prioritise resolution over burst depth. Shutter life is rated at 150,000 actuations — check via EXIF. The dual SD slots and weather sealing are practical features for working photographers. The D7200 (2015) addressed the buffer limitation and added Wi-Fi; the D7500 updated the sensor and added 4K video. Condition checks: verify all 51 AF points in the viewfinder, check rear screen, and inspect the card slot doors for seal integrity. One of the sharpest DX DSLRs produced.
