Septoria Leaf Spot, fungal.

Late Blight, P.infestans is a serious one .
Have you gone to the Disease Forum and looked at the pictures shown there to help make a diagnosis,that might help, especially the ones from Cornell.
Do you grow tomatoes near where anyone else grows them,that
s an issue as well.
Almost all of the foliage diseases are spread by wind,and/or,embedded in rain drops.So depending on the direction of the wind and how much rainfall,also is an issue.
Once you get more info about the above,the easier it is for folks here to make some suggestions for you to help prevent it in the future.
Hope that helps,

Late and early blight look pretty much the same to me. It came up in August. I had only had tomatoes a few weeks. There were black spots all over the stem and leaves which eventually went to the fruit and the plant would pretty much just die. Within two weeks of me noticing it, they were all infected and dying.
I'll see if I can find a photo
