Verdict
Pick Model A if you need the wider 17mm start and slightly longer reach at 35mm, or if the extra 10 EUR fits your budget. Model B stays the better choice if you prefer a more compact zoom range centered on 20-40mm and want to save money. Both share the same f/2.8 maximum aperture at their widest setting.
