My lens is dirty.

[Mr Felix]

Folks,

Last night I went out and was taking pictures with Nelly, Greg, Peter and....... (Sorry can't remember all the names).

But when I got home and was looking at the pictures I noticed spots on the pictures.

I took off the lens and looked: Nothing on the front or back, so I looked through the lens.

Zooming in and out I noticed some spots became obvious. Here is an example: (See below)
I'm not 100% sure those are the spots, but looking at pictures these seem to remain constant through out them all.

This muck seems to be "inside" the lens. Bad news I'm guessing.

Also - and I am not happy to say this:

My 550d.
A few times when I was shooting, the camera would go into sleep mode. Fair enough. When I press the shutter button to wake it up, the rear display wouldn't activate.

I hear the camera focus and if I look though the view finder, it was was awake.
What I had to do was press the PLAY/VIEW button and the display would then work as normal.

Sometimes it would come out of sleep mode ok, but sometimes not.

I'm guessing this too is not good news.

Anyone?
