Verdict
Pick Model A if you need a versatile zoom range with a brighter aperture at the wide end and don’t mind paying a small premium. Model B stays the better choice if you prioritize a lower price, fixed focal length simplicity, or lighter weight for dedicated macro work at 30mm. Avoid Model B if the listed weight (150 kg) is accurate—this is likely an error, but verify before purchasing.
