Verdict
Pick Model A if you need a faster f/2.8 aperture for low-light performance or shallower depth of field, or if the 300mm focal length better suits your framing needs. Choose Model B if the extra reach of 600mm is critical for your subjects and you can work with the slower f/4 aperture, as the price difference is minimal. Model A stays the better choice if portability and wider aperture are priorities, while Model B remains ideal for distant subjects where focal length outweighs aperture speed.
