just clean Your sensor, or send it for cleaning. there's no way You could see a hair if it was in Your lens.

I use a pinhole lens with app f200 to discover if their are any small specs of dust on my sensor, but any lens closed down should show you if you have a dusty sensor.

turns out its My sensor on my D3. I first used the lens on my D90 and didnt have the problem. thats when i used a 50 1.4 on the D3 and it had the exact same problems. i guess the sensor is dirty although there was practically NO visiable dust on the sensor

II have never used this lens stoped up yet till doing some long exposures at F16+ for nightime cityscapes. I got back to the hotel room to discover that there is about a hundred spots of dust and hair on the lens. the back and front elements are perfectly clean. The Uv filter is a little dirty but i did sample shots with and without and made no difference. there is no problem at 2.8 or 4. But at 5.6 there is a particial out of focus dust spots. Its more defined at F8. And fully covered by F16 and 22. I have never noticed this till now.
