When possible, I try to avoid Tiffen filters, mostly
for their mysterious tendency to "self-fog", requiring
diligence in checking and cleaning them at regular
intervals, unlike with any other filter brand I've used.
Best: use a step-up ring so that you can use common
larger filter sizes (these larger filters are also
easier to grab for rotation - and you can fit
standard-sized lens shades to them...).
