[Canon EF 135 mm f/ 2.8 SoftFocus]

No Post Processing!

The Canon EF 135mm f/2.8 With Softfocus Lens is a relatively small, light and inexpensive 135mm lens.

The unusual feature of this lens is its softfocus capability. The 135 L has a ring that allows continuous soft focus settings ranging from locked at 0 (none) to 2 with detents at settings 1 and 2.

Set at 0 (no effect), the 135 softfocus lens is somewhat soft open (f/2.8) and, like many other lenses, becomes sharper as it is stopped down. Corner sharpness trails the center of the frame by a stop or more. So this is a somewhat-sharp soft-focus lens? As Canon carefully denotes this lens as being "With Softfocus", a soft focus setting of 0 allows this lens to function like a standard 135mm lens.

Turning the softfocus ring past 0 dials in spherical aberration that produces a dreamy glow. The amount of effect is determined in part by the aperture and softfocus settings - and can easily be overdone. At f/2.8, a softfocus setting above 1 will probably be too strong for most tastes. Below f/4, a softfocus setting of 2 will likely be too strong for most people. Like many other aspects of photography, mastering this 135mm lens' soft focus effect takes time. Be patient and experiment with it. The ISO 12233 Resolution Chart sample crops for this lens include softfocus 1 and 2 examples.
