Why 1.4 instead of 2x extender?

I have used the Canon EX 1.4X II extender on my 100-400mm Canon EF lens and it works well with minimal loss in image quality. Of course, any extender will effect image quality to some degree with the 2X extender not only losing two stops, but also causing some image quality loss.
Not true. I have no apparent loss of image quality with my Canon 2x III, using my Canon 5Dsr, Canon 300 2.8 II lens.

First off, you loose two stops of light with the 2.0X and one stop with the 1.4X. Secondly, the 2.0X also produces softer images. The quality may not be good enough for your needs. You have to decide whether the loss of quality is OK, or not..
Have you ever used a 2x with a quality lens?
Canon 100-400mm II L with 2x III .
Among other Canon L lenses as many have shown here prove your statement as needing to be qualified to say with products except for Canon L lenses and converters.
With whatever you are using you obviously have severe problems with but it does NOT apply to Canon.

Your photos pretty much put an end to the debate. Any loss of IQ is pretty much undetectable when the right gear is used properly. Beautiful work!

That is the key of course, "when the right gear is used properly". Not every Canon L lenses give the same results with a 2X Extender. Some lenses are well known to give better results than others. Additionally, often the camera must be micro focus adjusted to get the best from a 2X extender/lens combination. And of course there is the photographer's skill knowing when and how to get the best from the combination. It's not as simple as just adding an Extender to any lens that will accept one and you're good to go.

True, but you still need the right tool for the job and the ability to use it properly. Regis has proven beyond a doubt that it can be done.

I shoot along side of Regis very often and much to the surprise of many he does not use a tripod, all hand held. So anyone here that continues to disbelieve that it can be done has most likely never put in the time and effort to try and see if it could work for them or you don't have the best gear. Yes you do have to micro-adjust and yes I'm speaking only for Canon because that seems to be the best camera gear that seems to work. I shoot both the Canon 300mm F/2.8 II and the 600mm F/4.0 and I micro-adjust for both the 1.4 and 2X extenders and also for two different bodies. When you look at the pictures that Regis has put up and refuse to acknowledge the facts then there's not much hope for you. Ladies and Gentlemen, it can and is being done!

Thanks to all for the many thoughtful replies and example images. Definitely gives me something to think about. I just have to get real and budget, not only money but size and weight as well. I enjoy day hikes in the national parks and probably have that in the back of my mind when thinking about gear: can I afford it, can I carry it, do I have to carry a tripod too, or can I get away with my monopod/hiking stick. I'd probably only carry the 24-105, already pretty heavy, and one moderate tele paired with one of the extenders.

The non IS EF 70-200 f/4L is the lightest weight option is you feel you need a longer zoom lens for hiking. The v III extenders are designed specifically for series II L lenses and there likely will never be a series II version of this lens. But, the modest 40% increase to 280mm doesn't buy you much, where suggestions made in this thread to crop are spot-on in this focal length range.
