Verdict
Pick Model A if you need a true 1:1 macro lens with a fast f/2.8 aperture for sharp close-ups and low-light performance. Model B stays the better choice if you prioritize versatility with a broad 18-200mm zoom range and don’t require the wider aperture or true macro magnification. Budget favors Model A for dedicated macro work, while Model B offers more flexibility for general shooting.
