Pick Model A if you need a versatile all-in-one zoom for everyday shooting, travel, or situations where you want to avoid lens changes. Model B stays the better choice if you prioritize ultra-wide-angle coverage for landscapes, architecture, or tight interiors and don’t require telephoto reach. The near-identical prices make the decision purely about focal-length needs.
