Any idea if the STM lenses cover C300, C100 sensor completely.

How is the quality vis-a-vis L series lenses?

Any one use it with the Dual pixel AF?
 
The STM just refers to the type of motor that the focus uses. Since they're Canon EF lenses they will cover all Canon crop sensors which the C100/300 are.
I only have the 10-18 (or whatever it is) new wide STM lens and it works fine with dual pixel AF.
 
The 18-135 requires the ef-s setting on the C100 or you can get vignetting when the IS is engaged. Can the C300 accept ef-s lenses?
 
All Canon lenses cover the C300 sensor, whether EF or EF-S.

EF lenses = cover photographic full frame sensors (5D)
EF-S lenses = cover APS-C sensors (7D, and C100/300)

Actually I prefer using EF-S lenses on the 7D/C100 because they're designed for that smaller sensor, thus are made smaller and lighter and cheaper. When using EF lenses on an APS-C you're wasting a big part of the lens.

STM is a new technology that insures silent focus for video recording. The technology is only available in EF-S lenses as of now, but will eventually reach the entire line-up.

When used with the Dual-pixel AF (C100/300 or 70D), they give you silent autofocus with camcorder-like accuracy. The 18-135mm STM is a brilliant general purpose lens for C100/300. I've come to prefer it to the 24-105L lately, because it's very wide, has longer reach and silent focus. Down side is the aperture changes during zooming, but I never zoom whilst recording anyway (and even the 24-105 f4 changes aperture during zooming!) and mechanically the L lenses are tougher.

Optically, they're just as good as L lenses.

One must-have lens for C100/300/500 users is the 299$ 10-18mm IS STM ultra wide angle lens. The 18-135mm is also a great general purpose lens. The 55-250mm IS is a very cheap telephoto with superb optical performance and IS for handheld work.

Well… Depends on how you look at it. It's been argued for years that when you use an EF lens on a crop body, you're getting the "sweet spot" of the lens which translates to possibly better edge and corner sharpness since the lens was designed to cover a larger imager.
 
I don't own the C300, but I'm pretty sure that it can accept ef-s lenses, but that it doesn't have the ef-s lens crop setting of the C100. Feel free to correct me. The S35 sensor is slightly larger than aps-c so vignetting can become apparent on some ef-s lenses. I noticed it on the 18-135 with the IS engaged. The 17-55 f/2.8 also had some serious vignetting. I never noticed it at all on my Tokina 11-16.

This is true. APS-C(like 7D) is 1.6x(compared to FF) and s35(at least the Cx00 series) is 1.5x.
 
Canon clearly states that both EF and EF-S lenses are compatable with the C100, C300, and C500.

How much vignetting you can tolerate comes down to you.

A lens designed for a much bigger sensor than the one it's being used on will likely have less vignetting. But not always.

Most EF-S lenses work very well on the C series cameras, but again how much vignetting occurs is a characteristic of each individual lens so research is adviced before buying. See how much the lens vignnetes on APS-C cameras and expect similar results when in normal mode and identical results when in EF-S mode.
