2010/8/3 Allan Derickson <alland435@xxxxxxxxxxx>: > But why then is the B IV hood just a shorty? It is dedicated to a Wide Angle lens and then to avoid vignetting. Sky graduated filters like the used with the Rollei filter holder need to work parallel to the lens but keeping certain distance to produce the expected effect, it's the reason the filter holder is fitted in the lens hood, I never perceived flare using this filter, the lens hood covers the same area with or without the filter.
