Question about aperture

[roboter22]

Whats the difference between a picture shot at f22 and f2.0 if in both cases the shutter speed was adjusted accordingly so both pictures have the same exposure?

like what bro Diavonex has shown, the DOF will be different.

Read the newbies guides on Aperture.

Seems that you have to really start reading...

He can start with his manual. It's in there too.

Roboter22, you use large aperture opening (i.e F1.8 or F2.0) to throw distracting background out of focus

Shooting at different apertures gives you different DOF. In addition, sharpness may vary across aperture. Lens may be soft wide open and diffraction may set in at very small aperture.

There are other issues like flare, CA, star burst effect and stuffs.
