Q: 8. Will this filter create vignette on hasselblad xcd 21mm?

A: Unfortunately, I cannot state for certain as we do not test specific filters on specific lenses for vignetting (to ensure all items we sell are sold in the same condition as they were received by the manufacturer, we do not open new products for testing purposes). As the Singh-Ray 77mm Thin Mor-Slo Solid Neutral Density 3.0 Filter with Front Filter Threads (10 Stops) is a thin filter, it should be a good option for use on the Hasselblad XCD 21mm f/4 Lens and I would recommend it for your usage needs. However, do note that this filter can be returned within 30 days of purchase date for a refund or exchange if it does not work for your usage needs.

Q: 10. How neutral are the Hoya ND filters?

A: They are very neutral. It does not reduce infrared but that is okay since it is only 3 stops. At higher stops the exposure will be longer and the infrared may cause color shifts, but at 3 stops an ND filter like this is still good since exposures will be shorter.
