Surely it cannot be the camera as i only bought it on friday just gone. its on other images also with other lenses too.  HOSTED PHOTO please log in to view hosted photos in full size.

joeseph "smells like turd"  More info | May 21, 2007 23:39 | #4 could well just be dust on the sensor - Canon sometimes gives this away free with expensive camera models. If it looks worse at smaller apetures (<F16) then it likely dust or other muck on the sensor. Either get real friendly with your canon repair center or learn to clean it yourself. some fairly old canon camera stuff, canon lenses, Manfrotto "thingy", and an M5, also an M6 that has had a 720nm filter bolted onto the sensor:

richardho11 Senior Member 850 posts Joined Jun 2005 More info |  Permanent banI would start with the Giottos Rocket blower. If that doesn't work, I have tried compressed air, but make sure the can is only 1/4 full and at least 6" away from the sensor and keep it upright. Then give it a few short bursts. It always worked for me. https://photography-on-the.net …p?p=2962090&postcount=534

If you purchased the camera from a 'big box store' There passably is someone there to help you, or take the camera back in return. If you made the purchase online the dealer may be of some help. I'm just a simple maker of love charms and tokens,who occasionally takes a picture or two.

Just Steve lately....
