Help understanding the difference

What is the main difference between the Canon EF-S 18-135 IS STM and the Canon EF 28-135 IS USM? The 18-135 on B&H is priced higher than the 28-135, which is a EF lens.
Is it that one has the STM and the other has the USM?

one is for a crop sensor only the other can be used on both. Also the efs I believe is a newer lens that came out recently

G, yes, the STM has a stepper motor. Those motors a more quiet so more suitable for video, since the whirls of the motor are not heard in the soundtrack.
If video will never be important to you, then get whichever will work best for how or what you shoot! ;-)

Thanks SS, I have the 28-135, which for me is great as I don't really have an interest in video.

The 28-135 is notorious for its lens creep. If your's doesn't display any you are lucky. The USM motor is faster than an STM motor, but the STM motor is quieter. The overall build quality of the 28-135 is probably better than the new 18-135, but the 28-135 suffers from a lot more chromatic aberration. The most noticeable difference for most people is the range. On a crop body, 28mm is not very wide. 18mm is a very significant difference. In general use, the 28-135 on a FF body provides a similar range to the Canon EF-s 15-85mm on a crop body. If you use full frame the choice is a no brainer since the 18-135 is for crop only. The 28-135 and the 18-135 STM both have full time manual focus, but the focus ring on the 28-135 has better control and damping while the focus ring on the 18-135 STM is electronically controlled, not as smooth or damped, and doesn't work at all if the power to the camera is off. Optically, the newer 18-135 if probably noticeably better in some circumstances, and is the one to use if you are using a crop body and are interested in video, especially with a newer Canon body like the 700D or the 70D. So, the choice of one over the other depends on the intended usage, the intended camera body, and an understanding of the limitations of each lens.
