Try to buy “digital” lenses.  One of the biggest differences between EOS lenses made for film cameras and those made for digital cameras are the anti-reflective coatings on the lens elements inside of the lens body.

Unlike film, digital sensor assemblies are capable of reflecting light back up into the body of the lens.  This can wreak all sorts of havoc on the image captured by the image sensor.  It frequently shows up as images with hazy looking, cloudy areas, or other weird lighting effects.  Digital lenses have special coatings to minimize the effects of light being reflected back up into the body of the lens.

The T3i is good camera to discover digital photography. One of the first things you realize is that you no longer have to shoot an entire roll of film with a fixed ISO.  The next thing you realize is the degree of control you can have over exposure.

Digital cameras are capable of automatically all three legs of the exposure triangle.  But, you can also set up DSLR cameras to control any two legs, any one leg, or none of the legs of the exposure triangle.

All you really need to know is, if the lens has the letters EF or EF-S in its name, it will work on your T3i. There are third party lenses but their naming convention is different.  Stick with Canon until you become more familiar with it.  Matter of fact stick with Canon period and all will be good.

Canon EF-S 18-135 STM lens is a good all around lens for the Rebel series cameras.

They are much better today then they were.  Especially if you choose wisely. Don't go third party if Canon has what you want.  Sometimes Canon doesn't and sometimes the off brand lenses supply that niche.
