Pick Model A if you need the wider 24mm field of view and built-in stabilization for handheld low-light shots. Choose Model B if budget is tight and the brighter f/1.8 aperture for subject separation and dim-light performance outweighs the 4 mm focal-length difference. Model B stays the better choice if you prioritize maximum light intake over stabilization and a slightly wider angle.
