the original pics Sue posted are on Flickr and better yet you can download them at the original full resolution (3264x2448)
Unfortunately, there are no pictures of the bottom of the damaged leaves to confirm aphids and or how many there are. The bottom of the leaves is where they hang out do most of the damage.

I looked closely at the high res pictures and cannot see any lesion that resembles EB. EB forms a concentric circle pattern as the brown lesion grows in size.

I've had similar damage on some leaves this year, no clear EB symptoms or any other fungi. The only thing I've found was aphid nymphs on the bottom of the leaves which only could be revealed under a magnifier or with a closeup shot with the camera. I have not yet seen a single adult aphid this year other than one flyer.
