It looks like you have a spot of dust, or dirt, on your image sensor.  DO NOT try to wipe it off. 

Use a blower to blow out the mirror box, while you hold the camera so that the dust and dirt falls out and away.

You have taken some nice shots.  Remember, though.  Wide angle lenses capture context.    You have a digital camera, take lots of photos at varying focal lengths.

The dust spot can be removed with post-processing software, BTW.

Waddizzle,

Thank you again, I will clean them up with post processing software, I just wanted to know what was going on.

Waddizzle,

What about this picture, do you think this is the same problem.

Word to the wise.  The photo of Big Ben is clean, and appears to be shot with a telephto zoom.  It appears that you changed lenses.  You took additional photos, but dirt has apparently appeared on your image sensor.

Under what circumstances and conditions did you change lenses?  The obvious assumption is that the lens change somehow introduced dirt into the camera body.  Try to remember exactly what you did when you changed the lenses.  Changing lenses outdoors on a windy day is begging for trouble.  My most common mistake is sitting in an air-conditioned car with the AC blowing on me, and changing lenses.

Be mindful.  Changing lenses in the field is a good way to dirty your camera.  This is one of the main reasons, besides speed and convenience, that pros carry mulltiple cameras.  They know changing lenses can dirty their cameras.

Yes, those look like the same dirt spots, in the exact same positions.

[Waddizzle]

BTW, a second look at Big Ben shows a dirt spot that appears in ALL of your posted photos.

Waddizzle,

Big Ben was taking on 12/18/16 at 10:57 AM London time and the othe two was take on 12/17/16 at 7:18 AM and 7:20 AM. I am not sure when I changed the Lens but I know I did at some point in my big purse I was carring, I tried to be careful.
