T4i / 650D Autofocus problem

Hi,

I recently got a 650D with 18-135 STM lense and still can't achieve anything close to reasonably fair quality, though I am not at all new to DSLR. 8 out 10 shots are blurry or even out of focus.

Here is the link to the photos I made:

For example, IMG_1092 is OK, while 1093 is too soft even for 18mm.

Could it be back or front focus?

I also noticed that LiveView focising is much more accurate than ViewFinder AF (see 1561 (View Finder) vs 1562 LiveView).

Some shots with high shutter speed and ISO like 1568 make me frustrated.

I tried turning on/off image stabilizer, checked all the apperture numbers, reset the settings, upgraded camera firmware but to no avail.

What do I do wrong?

Any advice is appreciated!

Canon EOS Rebel T4i (EOS 650D / EOS Kiss X6i)
