Having more lenses on a camera may be preferable for several reasons:

1. Versatility: Multiple lenses allow photographers to choose the right one for different situations, such as wide-angle lenses for landscapes and telephoto lenses for wildlife.

2. Improved Image Quality: Each lens can be optimized for specific uses, which can enhance image quality and performance in various lighting conditions.

3. Creative Flexibility: More lenses enable a wider range of creative techniques, such as bokeh effects with fast primes or dramatic perspectives with ultra-wide angles.

4. Adaptation to Subjects: Different lenses can better capture specific subjects, from close-up details with macro lenses to distant scenes with telephoto lenses.

5. Control Over Depth of Field: With a variety of lenses, photographers can more easily achieve desired depth-of-field effects, giving them greater artistic control.

Overall, having a selection of lenses enhances the photographer's ability to capture a diverse array of images and adapt to various shooting scenarios.
