With fast, sharp, prime lenses that are this small and compact, not to mention lightweight (you can carry one in your shirt pocket) there’s no need for zooms. Olympus makes the best zoom lenses on the planet, and for the last three years I have been using these zooms. This is uncharacteristic of me since I have always believed that prime lenses offered the best image quality. My use of zooms is mostly tied to bird photography. BUT! If I were not a bird photographer I’d switch to all of Olympus’ prime glass. There’s just something very freeing about knowing you have a lens in your shirt pocket that can produce world-class, super sharp, beautiful bokeh-filled, images, for just a little money.
