Canon T5i 700D focus problen

psdonald42 — Tue, 17 Mar 2020 13:54:32 GMT

Hello Community,

I'm new to this community and new to EOS cameras.

I have a T5i 700D camera and i have a problem with the focus on the final image.

I have used AF, manual focus and Live view. I have used 2 different lenses.

I notice it particularly when doing close up shots.

I get a very good focus either through the viewfinder or on the screen but when i take the shot the image is blurred.

I use a tripod so it's not me being shakey.

Any ideas for a newbie.

Thanks

Peter

How are you determining "focus"?

Are you closer than the minimum focus distance of the lens?

Are some parts of the image in focus while others are out of focus?

Can you post an example?

Hello kv,
When i say focus i mean that the image i can see on the screen or through the viewfinder is as perfect as i can make it with fine details being shown clear.
I then take the shot and the resultant image has lost the details and id blurred.
In other works what I see is not what i get.
I know you probably need details of my settings and an example and i can get that on here later. (not at home right now)

What magnification are you using to determine the quality of the focus? You might have expectations that are too high.

Hi there!

Which lenses specifically are you using, and how close exactly are you?

Like kvbarkley asked, if you can supply the community with sample images, and EXIF data that will be immeasurably helpful!

Are you saying that taking the picture with live view does not cure the blur?

What is your shutter speed? You may want to use the built-in shutter timer delay. Your hand can shake the camera when you press the shutter, which can cause a blurry photo when you have a slow enough shutter speed.

Sorry folks,

I got home and wanted to move this forward but my daughter boeeowed the camara for a few weeks.

I'll put this on hold until i get it back.

I'm doing some close ups of plants and on live view they look great. I would expect that the actual photo would be better than the tiny screen. My samsung S6 takes a better quality shot.

Your Samsung with its itty-bitty sensor also has a wide Depth of Field which may be the problem here.

Good point. But, if the image "looks great" in Live View before the shot, then DoF may not be the issue. Time will tell.

I'm not sure I'm clear on your use of the terms "live view" and "actual photo". Did you actually take pictures using live view? Or did you just turn it to live view to see how the pictures looked on the screen? And if you did take pictures in live view, did they come out sharp or blurry?

The point is that focusing through the viewfinder and focusing via the live view screen are two independent operations, with the live view screen always showing you what the sensor sees. If their results don't match, it can mean that the viewfinder's focusing mechanism is out of adjustment. In some higher-level Canon cameras, you can sometimes correct for that, but not on Rebels. If that's your problem, you'll probably have to send the camera to Canon for adjustment.

I hope you warned your daughter about the focusing problem.

She must get satisfactorily sharp photos? And you don't? Is that what you are saying?
