Pick Model B if you need the extra 50 mm reach at the telephoto end and can accept the slightly higher price. Model A stays the better choice if you prefer to save 9 EUR and don’t require the additional zoom range. Both share the same wide-end aperture and macro capability, so the decision hinges solely on focal-length needs and budget.
