Spots on tomato leafs

Dear all,
I'm trying to grow my own tomatoes and I've noticed that some of them are covered with light-brow spots. It looks like those spots are slowly drying out and than the dead matter falls off leaving a hole in a leaf.
Quite recently I used to have lots of microscopic caterpillars but I removed all of them (perhaps it's related?).

It might be tomato leaf spot - septoria - but I can't get a good enough close-up to see properly .
I'd remove the affected leaves - increase ventilation and decrease humidity.
Overwatering is the cause of many tomato problems - only water when the soil is dry an inch below the surface and water the soil only, not the leaves.
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
Could also be where the leaves have been splashed with water.
I often get very similar spots on the lower leaves of some of my toms when I realize they're getting too dry and water over-enthusiastically.
I ignore them.
But best to make sure it's not leaf spot though.

Knowledge is knowing that a tomato is a fruit.
Wisdom is not putting it in a fruit salad.
I don't think it's anything to be concerned about, as Pete says splashes of water, or could be weather related i.e. cold nights & warm days.
It should be remembered that there is a myriad of reasons for brown spots tomato leaves and you would drive yourself bonkers if you worried about all of them.
HI guys, thank you for you comments. I will sleep better now
Luke- perhaps I should add that if your tomatoes are under glass, you will soon need to be thinking of shading the glass as the magnified sun's rays will result in sun scorch.
A product called 'Coolglass' seems to be used widely.. this is purchased as white powder & mixed with water which is painted onto (or applied with a sponge) to the glass.
