Hi all, Thinking of getting CPL for the 16-80. Can it be stacked with the UV (Hoya HMC) or better to use separately to avoid vignetting? Or if i use slim one and stack will it still vignet? If it does, then maybe i have 2 options: - buy slim one (Pro 1) 62mm --->exp option - or buy regular one but 67/72 mm with step up ring --->cheap option Problem with step up ring is that i couldn't use hood or lens cap. Which option do you suggest? And if i want to take waterfalls with long exposure, ND4 or ND8 is better? Thanks in advance for the help bros. |

Best solution: ---> buy slim CPL 62mm without stacking for CZ16-80 Have try using step up ring to 67mm, normal Hoya UV coated filter, it still vignet. using step up ring to 67mm, Nikon NC filter, slight vignet. using step up ring to 67mm, Nikon CPL II filter, a bit vignet. And if you want to take waterfalls with long exposure, ND8 is better than ND4. But best is to use ND400. (Remember, manage to get 0.5sec to 1sec at ISO100 F32 with ND4 +CPL which I find the exposure NOT long enough) With ND400, you will better control on aperture and have super long exposure. |

Hi Mino, Thanks a lot for the answers, just what i needed. So for slim CPL what else to consider beside Hoya Pro1? I know B+W has slim one but no front thread for lens cap. And ND400 is how many extra f-stop? |

4x ND 0.6 = 2stops 8x ND 0.9 = 3stops 400x ND 2.7 = 9stops |

Jason, My newbie explanation: ND is to basically reduce the exposure by a few stops. Most common application is if you want to shoot waterfalls/beach with long exposure (1s or more) for that silky water effect, even with smallest aperture (biggest f number) you will still overexp. So ND has to be used for this. Or for example shooting sunrise with strong light in horizon, you can use graduated ND so that the foreground is exposed normally, but the strong sun is not overexposed. I hope it helps. |
