Using Diffusion Filters: A Comparison of LEE Soft Filters 1 to 5

I've used diffusion filters for years but rarely for their intended purpose. If you haven't heard of them before, diffusion filters are transparent glass or plastic sheets that go in front of the lens and diffuse the light as it enters the camera. The resulting images taken with a diffusion filter have an appearance of reduced contrast that ultimately looks hazy, offering a slightly dream-like effect.

Smooth Trans Focus (STF) was invented by Minolta in the 1980s and became available in the Minolta 135mm f/2.8 STF in 1999. The special design of the lens with an Apodization (APD) filter allows for the smoothing of out-of-focus areas, or bokeh.
