A few months ago we purchased a Canon EOS 80D that came with 2 lens, one works great and one is blurry. I tried calibrating it but its still not focusing. It looks decent at 18 but still not crisp and when I zoom in it increases in blurriness. Anyone have any ideas, suggestions, recommendations?? Not sure what to do at this point, maybe besides calling canon to get a replacement.
If the lens is within warranty, I would not muck about with it, send it to Canon for them to look at - that is what warranties are for.
There can be a few things that can cause this sort of issue. Before starting the trouble shooting make sure the switch on the side of the lens is set to AF. The first things to check when you are seeing an issue like this are your settings and the light conditions. If your settings are under exposing the photo by too much, or if the light levels are too low it can cause the camera to be unable to focus.
To test that put the camera into automatic mode and take it out in mid day when the light is the strongest. In automatic mode the camera should be choosing the best settings to get an even exposure and in mid day light there should be enough light and contrast that the camera should be able to catch focus.
If the camera focuses and takes a picture correctly in automatic mode at mid day that is an indication the issue was with shot settings and light conditions. We do have a helpful tutorial that goes over the different settings on our cameras and how they are used. The video series is available HERE.
If you take the camera out in mid day and it isn't taking focused photos in automatic mode it is an indication that there is an issue with either the lens or the camera body. To test which it is it would be best to put a different lens on the camera. If the camera takes focused photos with a different lens the issue is the lens you were using before. If it continues to be unable to focus that indicates the issue is with the camera body.
If the issue is with the lens try removing any filters that are on it. Sometimes if filters are on the lens they can alter the focus enough that the camera is unable to confirm it. With the filter off try taking another photo.
If the lens is the only lens with the issue we would recommend sending it in to the factory service center for repair. If the issue is with every lens on the camera body we would recommend sending the camera body in to the factory service center for repair. If you send the lens or camera in for repair make sure to include a copy of the proof of purchase in the box. The technician will need that to verify the warranty.
