Minimal colour shift and no loss in resolution
The first thing I checked was the colour cast that this filter might impart and any effect on resolution. The lens used was a Sony 24-70mm f/2.8 GM, a very sharp lens at 24mm. I found practically no colour cast and no resolution loss, keeping in mind that the sensor itself undergoes some reciprocity failure during long exposures (it's worse with film).
