Is it dust on your sensor?? Looks like it. You can confirm it by shooting it with another lens. Hope it helps and lens cleaning quite expensive.

It looks like sensor dust. Try taking with kit lens with small aperture (high F nos, eg, f/14 to f/22) aim at white wall.

Use blower to blow the dust.

Ensure your battery full (or close to full charge)
Go to your menu, look for cleaning mode.
Select that and it will lift up the mirror. Do not switch off yet.
Then remove lens.
Position the camera mount facing downward, then use blower blow the sensor. Careful not to poke the sensor :)
Replace lens, switch off.
Test do test shots again (with high f nos) on white paper/wall.

Repeat cleaning if necessary.
