Pick Model A if you prioritize saving money and don’t need the extra 50mm reach, as it delivers the same wide-end aperture and macro capability for significantly less. Choose Model B if the extended 250mm telephoto range justifies the higher price and you’re willing to pay for the added versatility. Both share identical wide-end performance and macro categorization, so the decision hinges solely on focal length needs and budget.
