What brand and model of camera will this kit fit?
This kit will fit any 58mm lens camera, the model of your camera is not relevant as long as it has the same thread size.
How can I make sure this will fit my lens?
This kit was designed for 58mm lenses.
The most important thing to do is find out the thread size of your lens, your camera's lens thread size will be marked somewhere on the lens barrel or printed underneath your lens cap. This number is always preceded by a "Ø" (diameter) symbol. For example: Ø58 = 58mm lens thread size.
What is each filter used for?
ND filters (Neutral Density) reduce the amount of light reaching the film without affecting the color. Can be used to enable slower shutter speeds. Also can be used to better separate subjects from the background by allowing wider apertures, effectively decreasing depth of field. Great for portraiture and outdoor scenes.
ND filters are quantified by their optical density, or equivalently, their f-stop reduction. Typically the amount of light reduction achieved by an ND filter is defined in stops, 1 f-stop represents a 50% reduction in the amount of light.
| ND Number Notation | Lens Area Opening | Optical Density | f-stop Reduction | % Transmittance |
| None | 1 | 0.0 | 0 | 100% |
| ND2 | 1/2 | 0.3 | 1 | 50% |
| ND4 | 1/4 | 0.6 | 2 | 25% |
| ND8 | 1/8 | 0.9 | 3 | 12.5% |
Situations where ND filters are particularly useful include:
- Smoothing water movement in waterfalls, rivers, oceans, etc.
- Achieving a shallower depth of field in very bright light.
- Reducing diffraction (which reduces sharpness) by enabling a larger aperture.
- Making moving objects less apparent or not visible (such as people or cars).
- Introducing blur to convey motion with moving subjects.
