In general, this lens is a solid advantage; there are no analogues of such glass on other systems. I recommend both DSLRs and mirrorless cameras (via an adapter). Excellent sharpness, which, unlike Zuiko 12-60, does not spoil the artistic drawing. The wide range of focal lengths makes it an excellent standard lens. The minimum focusing distance is only 20 cm - almost a macro lens! I have the second version of this glass, with contrast focus support, and on my E-pl1 the focusing speed is quite decent. I must add one more thing, since the 4/3 system is already dead, now these lenses are very inexpensive on the secondary market, I bought my copy a little less than a year ago for only 10 thousand.
