Review Excerpt

  • Very good image quality; Improved dynamic range & high ISO quality over T6i; 45-point AF system; Fast Dual Pixel CMOS AF; Improved buffer depth.

  • Default JPEGs slightly soft straight out of camera; Dynamic range & high ISO still lags behind competitors; No 4K video.

  • Read our Canon T7i Express Review

  • Terrific overall image quality for a 20MP 4/3" sensor; Very good high ISO performance this sensor size; Very impressive & improved AF performance; Extremely fast, responsive overall performance; New Intelligent Subject Detection AF feature works well; More video features; Outstanding IBIS.

  • Image quality not improved from (updated) E-M1 II; Faces tough competition with image quality at this price point, especially at higher ISOs; EVF feels somewhat outdated; Expensive for a Micro Four Thirds camera.
