Yes. 50% more. So your max optical zoom would be 18X. I had one with my S2 IS. Found I hardly ever used it, though.TLIII..
If you can bear another post from me...I tend to get fixated on gadgets I just HAVE to have. I went thru this with the S2 IS teleconverter. I used it a grand total of twice, and those times were just when it was new and I was trying it out. I would caution you to think long and hard to determine if you will really use it a lot. 12X optical / 48X digital is a LOT of zoom power..
I would however strongly suggest you get the adapter tube that is used to connect the teleconverter to the S5 IS. You can put a UV filter on the end of it. That way the adapter tube protects your delicate lens barrel if you drop it or bang it against something, and the filter keeps stuff from getting onto / into your lens. I got the adapter on eBay for about half what Canon adapters cost. It's just a tube with a mount setup on one end for the camera body, and threads for the teleconverter or filter at the other.TLIII..
Thanks for your comments.I am definitely going to get the adapter and UV lens...
If you add the 1.5 converter to the 5IS, and leave it on, you do not get a 18X lens..
Here's why- the lens at 12X is a 36-432mm. you add the 1.5 converter and you get 54-648mm. then 648/54=12X. it is still 12X either way, with or without the converter. the only way you will get the 18X is leave the converter off at use at 36mm then put it on and use at 648mm. so 648/36=18X.
Also. my super super strong advice is that when you get the 5IS or if you have it, leave the digital zoom permantly OFF. it only degrades the picture quality. you are not really magnifying the image you are cutting down on the number of pixels used, in effect cropping the picture. if you have a 8mp camera with a 4X digital zoom, and you use it, then you are now using a 2mp camera the other 6mp are not being used. this severely limits the image quality and put a real restriction on the max size that can be relaisticaly printed...

Good points. Also from my experience with using a similar converter on a different camera, it is really designed to be used at the long end of the zoom range, to achieve extra magnification. But zoom the lens out to the wideangle setting and vignetting will probably occur. In other words, the image corners are cropped and a circular image with dark edges results. So in practice the converter lens needs to be removed and replaced even more often than one might think at first. This needs to be confirmed by a user of this particular camera / lens combination, but it is very likely to be the case.Regards,Peter..
