Review Excerpt

Amazingly small for a DSLR; Great image quality for its class, including superb low light and high ISO performance; Generous JPEG buffer depth; High resolution.
Buffer depths are shallow when shooting RAW; Lacks GPS from the predecessor; No AA filter means it's susceptible to aliasing artifacts.
Read our Nikon D5500 Review

New sensor offers incredible performance; Excellent image quality at low & high ISOs; Very good dynamic range; Phenomenal 20fps burst speed & deep buffer; Very good battery life for a mirrorless; 4K video; Dual card slots.
Slow buffer clearing; Only one card slot is UHS-II compatible; Touchscreen underutilized; No lossless RAW compression option; No 4K/60p option.
