The principle of Composer is that it is a goal to selective blurring. In central position, the center of the picture is clear, and the closer end, more is unclear. This creates fade effects and very pronounced bokeh. Note that the larger the aperture, the greater the blur effect is marked. So to F / 2.8 there will be a net rather limited area, and F / 16 we will have at most a little fuzzy on the edges of the photo. The depth of field can also be off-center by adjusting the direction of the lens from the center ball. This allows some variety even if we obtain a certain deformation in areas of extreme blur.
An important point to emphasize is that the Composer is a fully manual lens. The development is done by hand, to change the aperture, the lens is inserted into the magnetic disks of different colors, etc. Moreover, the goal does not include electronic, so it does not "speak" to the case. That means, for example, information about the shooting (opening in particular) are not stored in the EXIF photo. Moreover, according to the boxes models, the automatic speed adjustment will be more or less well. In all cases, the Lensbaby works only manual. If that's not something that you feel to cope, then the Composer is not for you.
I am delighted to have bought this. By imposing constraints it allows me to understand the picture differently, but I am often surprised, generally in good results. We can do some pretty extreme things, or most of the picture is blurred what draws the eye to the depth of field. One can also use the effect more moderately.
A final point to note, the Composer is very modular. You can buy accessories macro, wide angle, TV, lenses that change the nature of the objective (soft focus, pinhole, toy, etc.) It adds to the fun of using this amazing goal that likes a little tweak.
