The final time I used the lens was at an automobile exhibition, where the lens' ability to render details in the available light situations was something which the EF 50mm f/1.4 USM can't be expected to emulate. Shown below are some photos of that exhibition, including shots of the promotion girls on duty.

You will also notice that details from bright light source, such as the spotlights used on the exhibition area, are rendered without any aberration, such as flare or coma, including out-of-focus highlights area. When Program A-TTL autoflash was used with the lens, exposure details were the same as with most EF lenses. This is because you will be shooting with the lens closed down to its middle aperture of either f/5.6 or f/8, depending on the subject-to-camera distance, as shown in these two photos below.
