Well, I'm curious Dennis. Were you inside a building, shooting through glass, or outside?

David I was outside on a great night and I have about twenty images with the same problem to some degree, I used the same lenses earlier on and the next day with no apparent problem.

Hmmmm... Very odd. It kind of looks like a nighttime version of lens flare - the kind you get during the day when you point your lens in the general direction of the sun. I can't really say I have a solution, but I wonder if attaching a hood to the end of your lens would help. One other thing... the shot seems a little over exposed. Were any of the other 20 shots less exposed and if so, was there less glare?

If you look in the center of the upper-left quadrant of your picture, you will see a faint and inversed REFLECTION of the well lit bridge in the center of the lower-right quadrant. So we know the reflection is coming from your subject. An unnecessary piece of glass (probably non-coated) is between your subject and the front element of your lens.

Tom, thanks for the reply, what you say is probably correct because I had just put U.V filters on the two lenses, both lenses are great perfomers until this happened, for night shots I will remove the filters and see what happens.
David and Tom, thanks for your replies,
Dennis.

You may consider removing them for all work. U.V. filters make terrific see-through lens caps but do nothing beneficial for your photography. As you can see, they tend to screw things up a bit. A good rule of thumb for filters is to use them sparingly and with great care. The optically coated elements in your lens are well suited to reduce lens flare by themselves. By adding a non-coated U.V. filter, you may as well be shooting with a 40 year-old non coated lens. On occasion, I require a slight magenta correction for that nasty blue haze of summer. I will use a WELL SHADED 81C when shooting film under these conditions, but prefer a post processing fix when shooting digital.
