A variable ND filter would help as well. You can change the strength of the filter after you focus without having to put it on/off.

| I normally get away with using Live View to focus when the ND filters are on -seems a lot easier than trying to put the filter on without moving the camera. I am sure there is a flaw with this method but seems to work OK for me. |

I just looked into it further and you are right. I'm not sure what made me think it was autofocus only. Maybe I read it somewhere that had wrong information or was confusing it with some other feature it lacked. That should help a lot.
Thanks all. |

I am not sure if that is what your problem is but even with ND400 filter I could see the image on the back camera screen of Canon cameras and could use autofocus in daytime shots. My Canon cameras had optical viewfinders so I could not see through them. With Sony now I can see both - through the viewfinder and on the screen, even with ND400 and ND8 stacked together. The only time I ever needed manual focus was at night when there was nothing to focus on (I never tried the trick with a torch).
I always thought any lens could be used for long exposure so I was surprised to see your question but I may be wrong ;) |

| You definitely need manual focus capability. You want to "lock it and leave it" after putting your filter(s) on. |

| You can set manual focus on your camera and then put the filter on. Otherwise choose the maximum ISO value and after manual focusing set the correct ISO/aperture/shutter for the shot |

| I've been trying to do long daytime exposures by using ND filters. Having limited success. If I use more than one filter my camera cannot see well enough to focus. Is it better to use a lens with manual focus capability, so I can focus and then put the filters on? |
