Would it also have aperture blades?


No. Partly because that's complicated and expensive and moving parts are
likely to break, partly because you don't want the depth of field to
change based on how bright it is. It'll use some combination of fiddling
with exposure time and CCD sensitivity, all of which is purely done in
software, to control brightness.
