That sure looks like lens flare to me but I bow to your greater knowledge in this area.
Cheeky monkey! I wasn't implying greater knowledge--I'm always trying to learn as well and I know from another thread (
http://www.thephotoforum.com/forum/showthread.php?t=16111) that you have the goods. I'm sure there is lens flare (lights at night almost always overexpose...but you knew that). I was eyeballing the noise more.
I was speaking from personal experience and I do like a good challenge. Hopefully, no harm done?
And onto the challenge itself. UD1: Your lens might be fine, but the weather might be a problem. That's what Hertz was talking about. Like when you take a cold can of cola out on a hot sunny day--the outside gets a layer of condensation. Same thing can happen with your lens.
I also see the "line" in the bottom left corner. Are you using flash? I know that flash can bounce against even the smallest particle and create stuff that you can't see in real life.
Barring that, try overexposing your film by a stop or two and see what happens. Also, if you have a lens hood, use it.
And if those don't work, get your developing done by a different company.
Like Hertz said, this is mainly about running down and eliminating the variables. If I haven't completely P'd him off, I'm sure he'll have more ideas too. Sooner or later, something has to work.
Let us know how things are coming along.
