Imaging Resource published their hands-on review conclusion:

Admittedly, the OM System 40-150mm F4 PRO lens is not the most exciting. There’s nothing about it that blows me away. However, don’t let that fool you. It’s a great lens. The lens offers excellent performance in a compact form factor at a reasonable price. It doesn’t include the faster F2.8 aperture of the larger, heavier, more expensive Olympus 40-150mm F2.8 PRO lens, but the new 40-150mm F4 is a compelling option for photographers looking for a compact telephoto zoom lens for their Micro Four Thirds camera.
