For portraits, the Zuiko 50mm (equivalent to approximately 100mm mm format) very suitable because of its intensity and the related exemption possibilities. In Intresse the person added, however, it is appropriate to the sharpness setting on the camera back without: The optics forms wrinkles, blemishes etc. from with merciless sharpness.
The lens is processed by outstanding, it is splash-proof and dust-proof. This means: Shooting in snow and rain, or on the sandy beach can not harm the optics. In conjunction with an E-1 housing I have already abgepült the optical system multiple under the tap.
I would have wished only that the focus area would be to fix. Because of the low minimum focusing distance the Focusierung takes quite a long time, when the focus point can not be found directly and the lens from infinity to close and must focussieren to infinity again. It is thus only a limited snapshot fit.
This lens is not cheap. But it is cheap in every sense of the word and therefore recommended every ambitious amateur unconditionally. Professionals, so they use the zoom range of the lens, the optics are certainly already own.
