The Tiffen 2 x 2" Black Diffusion/FX 4 Filter diffuses strong light entering the lens and produces a glowing effect. While the resulting image appears softer and ethereal, there is little loss of clarity or detail. This filter works by diffusing the light entering the lens with small aberrations; by spreading the light more evenly, a soft glow is created rather than the sharp, well-defined image when shooting without a filter. The 4 density provides more softening than the 3, but less than the 5.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 2 x 2" / 50.8 x 50.8mm.

Q: 8. What is the purpose of the Focus Hold Button?

A: For other lenses with this feature, the instruction manual states that when the Focus Hold button is pressed, autofocus function is suspended and the focus is fixed for shooting. The function of the focus Hold button can be changed on cameras with Custom Function capability. In practice, when you are in Autofocus mode, once you achieve the focus at your desired focus distance, you would press and hold the Focus Hold button. This stops the camera or the lens from changing the focus distance, so the camera will stay focused at the point until you release the Focus Hold button.
