Help! Rebel EOS T7 is very blurry!

[Colestrinity1]

Hi there,

I put a lense on my camera then took it off and put the original lense back on then all of a sudden the picture became very blurry. I didn’t change anything from when it previously was working. AF is on and when I tap the shutter to focus it does nothing. Please help! I just bought this camera.

OP states: "When I put the wide angle on the 18-55 lens it is clear but when I take it off the picture is super blurry. It was perfectly fine before I put the wide lens on originally." 

Sounds like OP is using one of those screw-on auxiliary lens. My belief is he might have affected the focusing of the base lens. That is why I posted the link to the process to reset the lens.

I was wondering if, in the process of screwing on or off the auxiliary lens, they had manually rotated the lens, which is not an STM or USM unit, and could have compromised the focusing mechanism.

My thought as well Trevor. Sounds like OP bought one of those packages with auxiliary lenses. T7 in the packages generally have the old style lens where the barrel rotates.

Those old lenses are a trap for young players... 🙄

The hard thing is the OP doesn't know enough to be clear and specific, and could well not realize they have rotated the lens.

That will do it! I guess those add-one are “lenses”.

Hi John, 
I was originally using just the 18-55 lens and everything was clear. I tested out the wide angle lens on top of the 18-55 lens, and it was clear too. Once I took the wide angle lens off the 18-55 lens, that’s when it became blurry. No settings were changed. I preformed the provided suggestions and still no luck.

Live view is blurry but the focus points are clear and so are the settings in live view. The diopter is set right where it should be. 

[Colestrinity1]

The diopter is set correctly. Unfortunately that’s not the problem.

When your are trying to autofocus, is there any clicking or similar sound from the lens?  I asked if you had moved the autofocus ring while in AF mode, when adding or removing the add-on optic?  THIS IS IMPORTANT!

My lens says EFS 18-55mm, Macro 0.25m/0.8ft. Hopefully that’s the information your asking for, apologies I’m very new at this. I tried to Manual focus on MF and separately tried to use auto focus AF by pushing halfway down on the shutter but it’s completely blurry, in both viewfinder, love view and after a picture is taken
