Pick Model A if you prioritize a slightly wider starting focal length (70mm vs. 75mm) and a lower price (34 EUR vs. 43 EUR) for a compact, constant f/4 aperture zoom. Model B stays the better choice if you need the extra reach (300mm vs. 210mm) and can accept the variable aperture (f/4-5.6) and higher cost.
