What reviewers say

Both reviews praise the convenient range, fast quiet autofocus and useful stabilisation, with substantial digital correction needed at 24 mm. Cameralabs finds consistently good results across the range on EOS RP and recommends it for travel. OpticalLimits finds softer long-end edges on a 45-megapixel body, better results at lower resolution, and less convincing value despite solid construction.
