I teasing you lah,
but there is some fault with the logic.
In digital applications,
there is no difference between a clear filter, or a UV one.
For both types, there are junk quality as well as super high quality.
Usually, besides the optical properties of the glass itself, a huge difference is because of the coatings used. The more, and higher-quality the coatings, the better. However, this is over-simplifying it as different metal vapours are chosen for specific reasons, so it's not just a case of wack a lot of everything is best. :bsmilie:
Bottom line?
For high-quality, multi-coated filters, it makes no difference whether a clear filter or a UV filter is used for digital, and it's probably easiest to just get those with more/better coatings.
However, if one gets a high-quality multi-coated UV filter, it can be used for digital and also be useful for film photography, in case one decides to try film photography at some stage. Clear filters will be of less use for film photography.
The Hoya PRO1D series of filters come in
BOTH the CLEAR as well as UV versions, so you have to specify which and not just say 'Hoya Pro1D'.
It's a pretty decent filter.
CHEERS!
