Verdict
Pick Model A if you want the slightly shorter focal length and lower price—its 100 mm reach and €35 savings may suit tighter budgets or closer working distances. Model B stays the better choice if the extra 5 mm focal length matters for your framing and you’re willing to pay the premium for it.
