Sensor Cleaning Question

[shoutinhalls]

Greetings all!

I am a very new photographer and think I may have gotten something on my sensor. I called a local place that cleans them but they gave me contradicting information:

First he said that the spots in my photos should not change size regardless of the zoom on the lens, then he said that it could change when I was just going to try and clean the lens again.

I am just trying to find out if the spots could be on the sensor and not the lens, even though they change size when zoomed in or out. Want to get that cleared up before spending $50 on something that may not resolve the issue, I already have checked the lens and see nothing wrong on either side.

These are two photos where you can see the difference of the spot in the top right corner

thanks!

Glad you got it handled.  I do still recommend buying a Rocket Blower, or any decent version of one. It is just a rubber squeeze bulb with a pointy nozzle that blasts air when squeezed. Squoze. Squozen.  90% of dust can be removed like that.  You won't want to go to the shop on a regular basis for routine dust removal just based on the inconvenience alone, never mind the $50 fee, and the blower is about the simplest thing in the world to do.

You don't say which Rebel, but follow the procedure for the dust delete data and take a picture instead of assigning dust delete data.

Do you have another lens?

Zooming by itself won't change the size of a sensor dust spot, but the spot will become more in focus, and thus smaller, as the aperture gets smaller.

Depending on which camera you have you may or may not have auto sensor cleaning. It occurs each time you shut off or restart the camera. You can also force it to occur by actuating the step with the red arrow in the screen capture below.

If you have a Rocket Blower (never use any canned air) you could try manual ccleaning - blue arrow.

You remove the lens, actuate manual cleaning and the mirror goes up and the shutter opens. Give a few puffs from the blower and see if you can dislodge the dust spot.

You can Google many vidoes on how to clean the sensor.
