My new Olympus 45mm lens is not any sharper than 14-41 kit lens. I don't think this is normal.

Can someone in the know please answer: does Olympus calibrate lens under warranty? (I tried emailing Olympus with this question, but received generic meaningless answer.)

What other lens calibration option are available in California?


What apertures and what focal lengths of the zoom are you comparing, and at what subject distances? The 45mm is best at f/4.0~f5.6 and the 14-42mm Mk2 seems best at f/5.6 for 14mm, f/8 for 25mm and f/8 for 42mm.

The 45mm is a portrait lens and I guess that can mean that absolute sharpness is not a high priority for portraits so wide open it falls off a bit. That's from examining the blur index graphs at http://www.slrgear.com/reviews/showcat.php/cat/7
