I know what you mean, I use a Motorola Pure edition it is 21 megs camera. The photos are just about as good on my Nikon D5500.. I find tune in Google. Zoom and or sharpen if needed. End results are reasonably good.

"It is what it IS" - Photography is in the "eye of the beholder" as long as it is not obscene or gross or illegal, I see nothing wrong with it. I don't think the subjects will object to your photographs as long as they are done respectfully.

Go to Google and search for: Back Button Focus:canon t4i or t5i.
Many sites this one seems to be good and clear to follow for Canon:
