Ive just bought my nikon D80 + 18-135mm and at the first night shot noticed a bright spot on the upper edge when higher ISO is on, above 400 is pretty visibile. The whole edge is brighter but the spot is the most visibile. The higher ISO the more visibile the spot.Sample of ISO 800 posted, the spot in marked area.Does anyone have any idea what could it be?

Thanks

This is possibly the amp noise issue that has been commonly discussed and makes the D80 less suitable for long, night exposures. Thom Hogan talks about this issue in depth on in his D80 review, www.bythom.com.

Have you got long exposure noise reduction switched on? It may help.

I switched long exposure noise reduction, it works great but over 8s so when using at 1/40 and ISO 1600 its very disturbing unless its on bright part of the shot.I case like this I need to use tripod - lose time. I would expect from such camera not to have this broblem, dont know if the others brands have the same problem.

I don't see any bright spot in your the picture you sent. I don't see anything brighter on the marked area. How big is it ?? Are we talking about a few pixels ??
