I've been shooting on Olympus cameras and lenses for over twenty years, so I know exactly how photos will turn out. The more important question is 'what should I shoot?' As an answer to this, I've focused on the theme of shooting in sunlight in a natural setting. I'm thoroughly familiar with the 40-150mm F2.8 lens, and it has the perfect balance of sharpness and softness. For this shot, I felt that backlighting was appropriate due to the model's white skin, different eye colour, and bronze hair colour.
The brightness of the widest aperture is a major advantage of this lens. As expressed in the photo, this is the best lens for me, because ever since I started using it, I feel like I've been able to expand my possibilities as a photographer.
