DSLR Mirror
All, and especially those who have Nikon D80 or maybe D200, I have a
question. I wanted to remove some piece of dust yesterday which started appearing on the shots at the same place and suddenly found that the mirror is not looking 100% clean as I would expected. I was using the bright light and was looking at the mirror under different angles. The central part of the mirror is perfectly clean but the other part of the mirror around this central "sub-frame" is looking a little bit foggy, but still as a mirror anyway. I also noticed two large circles of a perfectly clean mirror near two corners and two little bit smaller ones. It was looking like somebody just cleared the central part of the mirror but left all peripheral parts. Is that ok and should always be this way? I can garantee that nobody even tried to touch this mirror, I'm the first and the only one owner of this camera and this camera is brand new, I bought it 3 months ago from Costco. I sent my question to Nikon customer support last night because according to my previous experience with another SLR that I had before the mirror was perfectly clean and I expected this DSLR mirror should be clean as well. The support confirmed that the whole mirror should be clean and recommended me to go to the nearest store where I could fix that. I went to TempeCamera but these guys explained me that this is the part of the focusing system, etc. and it should be this way, everything's normal and I have nothing to worry about. Well, where is the truth? Maybe I'm too suspicious and it's really normal. I'm pretty sure that most of the people who read this NG know about this problem because sooner or later everybody has to clean his camera up to remove the dust. I didn't touch the camera or anything inside, just used a simple standard blower from the camera kit that I bought separately for that purpose, it doesn't have any visible dust particles now, but the mirror is looking strange from my point of view. Could anybody explain me that? Thanks, Just D. |

Jim,
Thank you for your explanation, I guess you're absolutely right, that's exactly what I'm seeing. Just D, "Jim Townsend" wrote in message ... These areas on the main mirror that let light through will appear slightly darker when viewed at the right angle under bright light. That's probably what you are seeing.. |

Front-surface mirrors such as the main one in an SLR are delicate, but if
necessary one can clean them carefully with cotton swab or lens tissue to remove stubborn grime that won't blow off. However such bits, unless really large, won't affect the image in the viewfinder and will never affect the picture. Toby "Just D" wrote in message ...

You've seen the explanation about the mirror. However, dust in your images are not from the mirror, since it flips up during the shot anyway. If you see dust on your images it's on the sensor behind the mirror. -- Ray Fischer |
