Nice setup. One good thing about the Cokin P series holder is it's still available new. _________________ Michael

Be aware before buying a VND-filter. Ask if both threads are the same. I have got one which has different ones. _________________ mpa |

No. I have tried daylight shots using welding glass with and without the eyepiece cover. When it's uncovered there's ghosting in the centre of the image if the sun is behind you or over your shoulder. It's a really low level of light getting in, but with the high level of filter on the lens it becomes significant. |

Good to know, thanks.
Of course -- dSLR mirror is only partially reflective, some light passes through to AF sensors. _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮

If you want a good nd filter i can recomend the haida 10 stop nd great and not to expensive hardly any colour cast |
chinese ebay seller told: VND filter ok til 200mm.
NBI: heliopan has digital filters. didnt check.
NBII: when i had ideas for pinhole-shift(lens)-adapter(before custom camera building came with its genious rotashift-lens for MF cams) i removed glass from VND filter. there was a japanese 4x5 cam having this tech inside.canon just announce a variable base 3dstereocam with similar idea inside. _________________ mpa |
