EF-S works on Ef to E mounts. On the a6300, for instance, the Canon EF-S 10-18mm mounted to a metabones EF to E adapter enables fast AF & IS. The EF-S lenses usually won't mount on e Metabones speed booster (but it shouldn't be mounted on it anyway since it's an apps-c lens).

One good reason to go EF is to allow you to use those same lenses on a full frame Canon DSLR. I haven't done a serious comparison of my EF vs EF-S lenses, but just from memory, I think the EF-S lenses have a bit of a clunky feel to the focus mechanism. I think it's not suitable to change focus while shooting video on those. Not saying the EF is much better. I mostly shoot with "L" series Canon glass, which is tighter feeling when focusing and more solidly built. The plastic EF-S lenses have lots of slop in the focus mechanism, IMO. Since so many Canon cameras come with an EF-S as a kit lens, I bet you could get a basket of them fairly cheap if you buy used.

The EF and EF-S designations are a little confusing. If Canon makes the lens, then EF means the lens will cover a full frame 35mm image sensor, and EF-S means the lens will only cover an APS-C sized film sensor. Also, EF-S lenses won't fit onto a full frame Canon camera, and they aren't compatible with some aftermarket EF lens adapters (like the Metabones speed booster I mentioned).
However, if a third party lens maker like Sigma, Tamron or Tokina makes an EF lens, it may cover an APS-C sized sensor or a FF sensor, so you need to check. And any EF 3rd party lens will fit on any Canon camera, even if the lens is only designed to cover an APS-C sized sensor.
Generally, the best lens for an APS-C sized sensor (or S35 size-- they are about the same size) is a lens designed for APS-C. And same with full frame glass for a FF sensor (Canon EF lenses). But, since the selection of lenses that are built for APS-C sized sensors is generally limited compared to FF glass, people often use lenses like Canon's EF 24-105mm f/4 on their C100/300 or 70D and ADD cameras.
It's a weird problem actually. Sony sells more APS-C cameras than FF, and all their ILC camcorders (just about) have APS-C/S35 sized sensors, however Sony doesn't even make a standard 16-50mm f/2.8 zoom in e-mount. Like I mentioned, people love the Canon EF 24-105mm f/4 lens on their Canon camcorders, no matter the camera. So that's a good lens to look at. It can be found new for under $600. The new version II is about to ship, and reviews I've seen say it's a little better, but it will sell for its full retail price of $1,100 for a while before dropping. So, for the money, it's probably not as good a deal for now.

For dim interior shots, f/4 is too slow for the FS5/FS7. That's why I was really hoping he new 18-110mm Sony cinelens would have an f/2.8 max aperture. Oh well.
Imho, f/2.8 will just sneak by in low light, but not really low light. What I've done is paired two FF Tamron zooms (the 24-70mm f2.8 VC with he 70-200mm f2.8 VC) with a Metabones speed booster. So the result is e equivalent of a 17-50mm f/2 lens and a 50-140mm f/2 lens. I know a great gray market seller who sold me the lenses for $800/$950. They came clean, unopened, and factory fresh. I'd list here name now if I could remember. But, optically I think they are incredible, and the IS (VC) is really good too. I have a small Rokinon 12mm f/2, so between those three lenses, I can cover about anything. Throwing a Sony 35mm or 50mm e-mount prime in the bag would be really easy to do since one lenses are really small.
That's my take on it anyway. Good luck!

Hi Barry
I was interested in the Tamron too. But lens and speedbooster ultra is quite a lot of money.
Went to the shop today with my FS5 a commlite adapter. We tried some things:
With Sigma 18-35mm art with both commlite and metabones no exposure and focus control
With Canon 50mm no control with the commlite only exposure with the metabones.
They didn't have the sigma to e-mount adapter. Anyone used this with the sigma lens?

Sigma 18-35mm f/1.8 will work perfectly with Metabones adapter (regular non speedbooster type). I have a Mark IV version of it. I'm actually surprised the Commlite adapter didn't work perfectly with it too.

You will find that Canon made EF-S lenses are differently constructed at the rear and won't fit on a Speedbooster as the plastic housing surrounding the rear element extends too far back. Happily, if you're feeling brave, the housing is removable, allowing you to fit the lens, which is why I can mount my Canon 17-55 2.8 EF-S to my EF-M4/3 Speedbooster XL. Most 3rd party lenses designated EF-S don't have the extra housing and will mount quite happily. Depending on what sensor you're adapting to and which FLR you're using, you may experience some vignetting at the wider focal lengths (said 17-55 vignettes slightly on my GH4 via the Speedbooster XL, but doesn't on my Commlite focal length reducer).
