Drop-in vs screw-in fil­ters

Amateur Photographer - - Technique -

There are two main types of fil­ters avail­able and the op­tion you pick usu­ally de­pends on your bud­get. Screw-in fil­ters, as the name sug­gests, screw on to the front of lenses and are small, light­weight and gen­er­ally less ex­pen­sive than the drop-in type. Their dis­ad­van­tages, how­ever, are that you have to buy them in the right thread size for each of your lenses, so you can end up with two or more of the same filter type.

Drop-in fil­ters drop into a holder that at­taches to the front of lenses via an adapter ring, and to use them on dif­fer­ent lenses you sim­ply need the ap­pro­pri­ate size adapter ring for each lens. The main ad­van­tage here is that you only need one set of fil­ters for all lenses, and fil­ters such as ND grads, while avail­able in screw-in ver­sions, are much more ef­fec­tive when they’re the drop-in type.

The most com­mon filter com­pa­nies in­clude Lee Fil­ters, Cokin, Hoya, NiSi Fil­ters, For­matt- Hitech, Kase Fil­ters, B+W and many more. Drop-in/sheet fil­ters also come in dif­fer­ent sizes with 70mm specif­i­cally for smaller mir­ror­less cam­eras, 100mm for most cam­eras and lenses, and 150mm fil­ters for use with ul­tra-widean­gle lenses such as the 14-24mm f/2.8 and widean­gle tilt-and-shift lenses.

Screw-in fil­ters are small and light­weight
