If your images were all blurred when set to Av-mode then your shutter speed
was too slow, despite your OS feature and that can only happen when your
selection of ISO was also too low. Everything good requires practice, even
thought the act of practice can be very frustrating and discouraging.
Progress comes from "persistence" and that is the secret of success
in absolutely every endeavour, including love. You certainly embraced the
the persistence element associated with going out every chance you get
and that persistence has paid-off well. So many people find every excuse in
the book not to go out and their photographic portfolio reflects that inertia.
Selecting your most productive ISO and aperture can be done without even
looking at the camera, while you walk, or stand and wait. ISO: turn on the
camera at the hip, push the button, immediately crank the ISO up, or down,
as your brain directs, and then hit the compensation button, while the camera
is still away from your face, dial up 1/3 stop, or down 1/3 stop depending on
whether you are in shade, or the sun emerges, or you are now facing the sun
and need compensation to the right instead of the left, and re-set as needed
without even looking through the viewfinder. Sometimes your estimate turns
out to be incorrect, especially if the camera controls didn't respond as cleanly
as you anticipated, but with practice you can get very good at it. You do this
automatically while your eyes are searching for a twitching leaf. I even did this
with my Canon G9 before acquiring a DSLR at least when it comes to selecting the
the most appropriate ISO, which was dialed in without requiring the menu on the
screen ... it had a separate manual dial.
