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.

I don’t hear a clicking noise but I do see the camera trying to focus. On the auto setting, I can’t ever take a picture. There could have been a possibility that when I put on the extra lense I may have twisted the auto focus ring.

If you did then your symptoms make sense.  The version of the lens you have must not have the manual focus ring moved unless in MF mode.  If it is moved, the drive mechanism gets out of sync, and although it is trying to focus, it is no longer aligned properly so will not do so.

I understand there is a fix for this, but as I don't use that version of the lens I don't have it to hand  So I shall leave it to my esteemed colleagues to provide those details.  In the meantime, I suggest you do not manipulate the lens in any way, be patient and we may be able to get this sorted for you without having to get a service tech to do it.

Thank you Tronhard, I appreciate it!

Really curious as to why you need a wide-angle adapter in the first place. An 18mm is pretty wide. If you want wider, get a 10-22 or 10-18mm lens.

Sure, you can screw on a wide-angle adapter, but you have to unscrew it to get the longer length of your lens. Kind of defeats the purpose of the lens. And they don't do anything good for image quality.  Better off having another lens.

JH posted a link to the fix. Click it and then follow the instructions. Afterwards throw that add-on WA “lens “ in the trash. 
good luck

Without being able to physically see the lens my suspicion is that the lens is damaged. Do you have a camera store nearby?

Thanks John, I found the link from your post and have made a copy of it for future reference.  Frankly, I think there should be a warning about this in the manual, or better still, as a slip of paper attached to the lens.  I referred to the manual of the T7 and there are safety advisories but not on this subject!   Of course, that only works is someone actually refers to their manual - which seems to be unheard-of these days:☹️ hence the piece of paper...
