Photozone has published a new review on the Olympus 40-150mm f4-5.6 lens. As you will find out quickly through this review, the Olympus 40-150mm is not a high-end lens. Its a good valued lens that produces nice images at the short and medium ranges. Its a relatively compact and light lens that works well on Olympus bodies (remember, your non-stabilized Panasonic body will struggle with this lens, especially near the long end).
