My general experience with Japanese dealers has been superb. But if you are seeking a bargain, expect at least some cosmetic issues, including rangefinder haze. For very dim light, I just attach my Nikon F eyepiece magnifier for critical focus of nearby detail. For infinity scenes, you just twist the lens all way to the infinity stop and don't even worry about the rangefinder. But so far, I've gotten precise focus every time, regardless of the varied lighting conditions. It's a very sharp lens, yet with pleasing out-of-focus rendering too, if that is what you desire.
