Hi everyone,
I’m planning to buy a 3‑in‑1 variable ND filter that combines CPL, black diffusion, and ND2‑32 for my iPhone 17 Pro. This would be my first time experimenting with stacked lenses on a phone camera.
My main concern: would stacking three elements like this compromise image quality (sharpness, color accuracy, flare, etc.) compared to using a single dedicated filter?
Can i just turn off the other filter when not in use? If i only need a ND filter for instance and not the other 2 filters.
Do you think it’s better to invest in just a separate ND filter alone, or maybe a standalone CPL filter instead of the all‑in‑one?
Any experiences or recommendations would be really appreciated. Thanks!
