[QUOTE="BackdoorArts, post: 372426, member: 9240"] That is definitely light leak. I remember someone else posting about experiencing light leak in other parts of the camera (IR sensor?) and needing to cover their entire camera with a handkerchief for long exposures. I believe it may even have been a D300. Regardless, you[I] shouldn't[/I] need to do that on [I]any[/I] DSLR. Was the lens cap and eyepiece covered shot taken in a fully lit room? Ideally, what you want are two long exposure photos with the only difference being the eyepiece cover on and off. Regardless, with both covers on it should be sealed off from extraneous light - though I would posit that the snap on lens caps may not be all that light proof and if left on for 30 seconds in a lit room I might not be surprised to see this pattern. I definitely think you have light leaks in your camera, but to be sure I would ask you do this. 1. Take a normal, long exposure shot as above. 2. Take the same shot with just the eyepiece covered. 3. Take the same shot with both the eyepiece and the rear IR sensor covered. 4. Take the same shot with a cloth over everything but the front of the lens. Comparing those shots should be sufficient to determine where light is leaking into your body. If it's anywhere besides the eyepiece then they should be sent to Nikon and you should get a new camera - or they should offer to seal this one properly. [/QUOTE]
