Pick Model A if you need a wider starting focal length (10mm) for tight spaces or broader scenes, or if a lighter, more compact zoom is a priority. Model B stays the better choice if you prefer a faster constant f/2.8 aperture for low light or shallower depth of field, or if the 20-40mm range better suits your typical subjects. Both share the same used price, so the decision hinges solely on focal range and aperture needs.
