Review Excerpt

Higher resolution and better image quality than SL1; Much improved dynamic range; Excellent Dual Pixel CMOS AF; Compact body with improved ergonomics; Articulating touchscreen; Full HD movies up to 60p; Better battery life.
Shallow buffer depth with RAW files; Dynamic range and high ISO performance still not as good as leading competitors; No 4K video option; OVF only offers 9 AF points.
