- i have a canon 75-300mm zoom lens and when ever i use the lens it leave mark on my picture i was wondering if there is anyway to fix that??
Can you show us an example of this "mark"?
Chances are it is not on the lens, but the sensor, like in my image here:
See the blotch by the wing?

Hello, grayden_O!
That is dust and lint on your sensor. Since your Rebel T7 does not have a built in sensor cleaning function, you have three choices. 1) Have a local camera shop clean it. 2) Send it to Canon for a cleaning. 3) Buy a cleaning kit and do it yourself.
You could start by just buying a Giottos Rocket blower [Screenshot included below to facilitate conversation], which you should have anyway, but it will help remove any loose dust and lint on your sensor, lens, and camera. But you may need a sensor brush or even a sensor swab if the smaller ones, as shown in your image, are stubborn. If you are at all squeamish about fooling around in the mirror box, options 1 and 2 are the way to go.
