Pick Model A if you need a wide-angle zoom for landscapes, architecture, or tight spaces and prioritize a broader field of view. Choose Model B if telephoto reach for portraits, sports, or wildlife is more critical, especially at a lower price. Model A stays the better choice if you require ultra-wide coverage, while Model B’s longer focal range and stabilization make it the stronger pick for distant subjects.
