Tomato Leaf ... Is it serious

My tomato (Black Krim) has some black / brown spot.  Now I did put my toms outside, it did get a bit windy and since then I have been putting them in the greenhouse.  Its not only my black krim that has this though ... one other tom has it too but its only on a few leaves.  I have quarantined them ... is it just leave damage as they were blown about a little last week or something most serious !!!

Yippie the attachment worked .... only has taken me an hour

Tomato leaves have the nasty habit of developing a quite alarming range of spots and lesions, and of course most of them have you quietly panicking and trying not to think of the "b*****" word! 

Given what you have done with yours and the time of year it's much more likely to be patches of sun and wind scorch, especially if the leaves were wetted at any time.
