Yes, the only lens filters that requires a different size lens cap are our variable ND filters.
All of our filters include a front thread which allows you to attach a lens cap to your lens filter when it is attached to your lens. The only exceptions are our variable ND filters.
Variable ND filters use a larger layer glass to help avoid vignetting, so your normal lens cap will not fit. For variable ND filters, you need a larger lens cap. Refer to the table below for the relevant filter cap required for each size of our variable ND filters. We sell filter caps individually, which can be used as a screw in lens caps for your filters.
