(I am a very new member to this forum, so if this topic has been done before (I haven’t found it) please point me there.)
My thinking is this. The latest APS-C cameras are extremely capable, whether we are talking the 70D or the N**** D7100, as examples. I know there is an ongoing debate as to whether “real photographers shoot full frame”, but for me (currently with a 600D but thinking where to go next, for reasons that I do know) I doubt whether I would ever want to: a 70D would provide me with all the growing space I am likely to need.
I also want to keep weight down as low as I can (ageing body

).
However, Canon’s top line “L” lenses are designed to work an all today’s Canon bodies, by definition – that’s what an “L” lens has to do.
That means, with a crop body, I would only be using about half the glass, if I traded up to “L” lenses.
I don’t mean to start a debate about the relative merits of different lenses. My question is simply “Is there a market for top quality Canon lenses designed for crop cameras?”
In my case, I think yes. Obviously depending on quality of image and manufacture, cost, size and so on.
Any views?

The latest cameras regardless of sensor are extremely capable.
While there is forum sponsored debate as to who may use what, as in the existence of a forum encourages the debate, in practice if you don't turn out quality work, there is little to debate. This forum seems to thrive on sensor measurebations... Fredmiranda has conflict of interest problems, while GetDPI is just a low user base forum.
To make things interesting, When YOU say full frame, YOU(and many here) are referring to 35mm sensors. Almost ALL of these sensors, save for two from sony, one from pentax and two from nikon have anti-aliasing filters, which significantly smears fine details(the 7D was awful in this ONE regard).
Others may refer to full frame as the full 645 format, or the full 6x7 format. There are cropped and full frame medium format digital sensors available. The one I use is something around a 1.1ish "full frame" crop, but I use that on a 6x7 camera... which makes it a 1.8x crop if you want to go from 35mm format to 6x7 format lenses, as my 90mm acts like a 50mm with an extremely wide aperture.
I absolutely despise the full frame moniker as it is used to imply superiority where there is none(all you absolutely insane 5D2 owners...sorry your cameras are not worth $1500 used!) and used to demand much higher prices(hi 5D3 owners).
Ultimately, you want a system that delivers high image quality with low weight. The expensive end of the EF-S lenses deliver excellent image quality on any of the cameras that canon offers. However, nikon offers crop cameras WITH OUT an anti-aliasing filter, so if we hold the systems constant for weight, and then compare on image quality, the system without the AA filter is going to handily out-resolve anything canon has.
The now older canon 7D and a 17-55mm F2.8 IS USM lens was and remains to be a supremely terrific combination. I wish I had not sold that camera and lens STILL, even after switching to medium format digital - but there was a very rare and unique price point opportunity I could not ignore.
Nikon's standard zoom for crop has weather sealing...where as we get image stabilization.
