Canon EOS Rebel t6 or lens issue?

IMG_5615.JPGMy Canon 75-300mm lens gets blurry when I try to zoom in on a subject.  I tried to have auto focus adjust the picture but still shows blurry only when zoomed in.  Could it be an issue with the camera?  lens, sensor or mirror?  I tried cleaning all of them but no changes.  Any guidance would be greatly appreciated.

Welcome to the forum. 

What settings do you have when you took the photo. Most cameras in AF mode won't actuate shutter if the camera doesn't achieve focus.

I am not 100% sure.  I just tried on automatic A+ 500 8.0 ISO 800 and is still blurry.  It does it with just manually focusing also.

"Could it be an issue with the camera?  lens, sensor or mirror?  I tried cleaning all of them but no changes."

 

Judging from the hazy image, cleaning may have been a mistake.  Send your camera to Canon for a cleaning and checkout.

Find a subject about 10 feet away. 

Take photos at several zoom settings, like 75, 100, 135, 200 and 300. 

Do any look good?  

Do you have another lens to try? Or can you borrow one from a friend?

 

Are there any filters or anything on the lens? If you hold it up to a light and look through it is it clear. Don't look at the sun.

Did the problem start right after the cleaning? Even the most conscientious shops can sometimes mess up a sensor cleaning.

If you can do the troubleshooting I mentioned above we could provide better guidance.

OK here is what you need to do. None of the above really gets you anywhere until you do this little test. Being it is  T6 you most likely go the standard kit lens with it the 18-55mm zoon?

 

Now, first reset the T6. Menus tools, cleat all settings and clear all custon settings. Mount the kit18-55mm zoom and set it to AF. Set the T6 to "P" mode, ISO 200.  Focus set to One Shot, do not use Ai-servo. Now on a nice sunny day go out side and take a dozen shots of various things. If the pictuers are good and nice there isn't anything wrong with the T6 and the problem lies with the 75-300mm zoon lens.

 

The down side to this is, the 75-300mm lens isn't a good candidate for repair unless it is very minor like a cleaning. IMHO, a micro fiber cloth is not a good item to use to clean the lens element.  You need a real lens cleaning cloth like what you get from your eye doctor.  You can buy lens cleaning cloths from Amazon and Walmart and others. You can ruin a lens cleaning it improperly.

 

Do my simple test first.

BTW. do make sure there is nothing attached to the front, or back, of any of your lenses.  Especially cheap filters.
