Where to send glass for calibration

This might be obvious to you, but I'm new... What kind of checks can I do to my camera and lenses to make sure they are focusing properly and aligned? And where can I send them for that? I live in a relatively small town, no big fancy camera shops here. I'm not skilled to do it myself.
I'm having some focus issues and I'm trying to figure out if it's me or maybe there is something wrong with my camera/lenses.

Thanks!

What camera and lenses are you looking to adjust?

There are dozens of ways to test things out at home before you send something off to be checked, and if you don't take the time to check it before you send it in, how do you know it's any better when you get it back?

First things first- eliminate as many factors as you can. Place your camera on a tripod (or a table if you don't have a tripod), set your camera on manual, single shot, and have good light available, and enough space. Have a good contrast target for your camera to focus on- any black and white focus chart you can print off online works.

Take several shots with the setup, both with and without using live view, and moving the focus ring with your hand in between each shot, so the camera has to refocus. You often will see a row of batteries, slanted ruler, or cereal boxes used- it doesn't matter what, but have something with some detail on it even with your target, in front of your target, and behind your target.

Then you start looking at the pictures to see if you have any front or back focusing issues.

You can also google the dot tune method as well.

I would only check my 28-135mm/3.5-5.6 lens and T4i.
I will try what you've described above

Interested to know what others say, but I always thought to send Canon gear to Canon repair shops for alignment if I can't figure it out by myself through AFMA or other techniques. Makes more sense for expensive bodies and glass though.

For what it's worth - literally, because adjustments can be relatively costly - you won't see much of an issue with focus with a 28-135 on a t4i unless it is totally out is whack. The physics of that combination creates a fairly large margin of error for focusing.

What is making you think the camera/lens has issues? Share some sample photos?

first you can figure out if somethings wrong with your lens by doing simple tests...put the camera on a tripod, if you don't have a tripod find some sort of stable surface(table top, etc.)...put the lens at it's fastest aperture, and line up things on a diagonal...people like batteries, but things without rounded edges are usually recommended...books work well...aim for the center book, and if it's focus, your fine...if one of the books in front or behind is in better focus, you have an issue...i'd say 9/10 focus problems aren't to do with the lens, or camera, but the shooter and their settings.

It probably is the shooter. But i'll try just in case. How far do I need to line up the objects?

E. J. Peiker performs these tasks professionally.
Here is a link to a page on his site that has some info on lens & body calibration:
http://www.ejphoto.com …ate%20Schedule%​202014.pdf
The info you want is about 3/4 of the way down the page.

I told him that you may be interested, and he said:
"Have her email me at ejpeiker@cox.net for more specific info and possibly finding a time slot."

You camera does not support "micro AF adjustment" You'll have to send it in to Canon for any adjustments. I suggest when you send it in send your lens with the body. Also, get the lens cleaned and calibrated along with the camera. Canon will fix anything they find in both items. The lens and camera will be returned not only cleaned, calibrated, but calibrated to that lens. Good luck.
