T5I camera...when i push the shutter button down, the lens just goes in and out and wont focus. My older ti camera did the same thing and i was told something was wrong with my camera. Evidently not true. I have 4 different lenses and the same thing happenswith all of them.. Not sure whats wrong

It sounds like it is hunting for focus. Consumer level cameras sometimes have difficulty achieving focus in dim light, even when it does not seem all that dim to you. I will bet that it does not do this outside on a bright sunny day.

That can be frustrating, but there is not all that much you can do about it.

What focus mode are you in? Don't use ai servo unless tracking a moving target. Use ai focus or one shot. That may keep it from hunting so much.

Thank you,  we were in the Local desert at a race, perfect morning, no clouds. I will check the settings and let you know!!

Thank you again for your response

could the lenses themselves be a problem.. as in dirty? or would it be a camera issue only?

[ScottyP]

No way 4 lenses on 2 cameras doing same thing is dirty lens problem.

Check the autofocus modes as above.

Also, are you shooting the standard way with your eye looking through the eyecup on the viewfinder? If you are instead shooting using the LCD screen (live view) the camera will also struggle and hunt a bit more to focus.

What were you trying to focus on? Camera needes something with contrast to lock on to. If its just sand and sky you may not have had a suitable subject.

That sounds right. I had a confirming experience a few years ago when I bought my 50D. When I have a choice, I like to pose as a seascape photographer, so I got on the subway and rode out to a harborside park to try the camera out. It was a hazy day, and I had the devil's own time trying to get it to focus on infinity, though nearby objects (rocks, picnic tables, etc.) presented no problem. It wasn't until sometime later that I realized that there was nothing wrong with the camera or the lens; the background of the scene just didn't have enough contrast to be auto-focused on.

If AF won't work in a situation when there is little or no contrast, try manual fcous. And use liveview with magnification to check if things are in focus and then press the shutter.

This is just for emergency if the lens keep hunting and you want to take a pic.

Yes, it is the camera.  Although I admit it seems ironic since you say two bodies do this.  A very easy way to find out.  Try the combo in a well lighted normal scene area and see if they work.  Whether the camera is faulty or you have an improper setting is where you should start looking.
