I got a refurbished Rebel T7 to give as a gift, and noticed that the lenses don't seem to retract their focus on poweroff like they do on my T8i--I tried both the kit lens it came with (18-55mm IS II) and my 50mm STM. I have to retract the lens with the focus ring manually.
Is that how the T7 is supposed to work? I read elsewhere that auto retract might be a feature only implimented in later processor cameras, but wanted to make sure it's not faulty before I give my gift. Thank you!

Well thats interesting.. never knew a rebel series did this:
T8i supports this under the following conditions
C.Fn 14: Retract lens on power off
You can set whether to retract gear-type STM lenses (such as EF40mm f/2.8 STM) automatically when the camera's power switch is set to Power off.
0: Enable
1: Disable
Caution
With auto power off, the lens will not retract regardless of the setting.
Before detaching the lens, make sure that it is retracted.
Note
When [0:Enable] is set, this function takes effect regardless of the lens's focus mode switch setting (AF or MF).
However, the T7 does not support this feature

Here's an article from Canon about the various types of lenses, including which ones are gear-type STM lenses.
