Indeed. Having a merging of technologies misusing terminology just confuses
the whole issue. No doubt why most manufacturers go with things like "FX"
format, etc.
Of course, what is 35mm film? 36x24? Well, maybe for stills. 35mm motion
picture format (Academy Crop) though, is 22x16. Does this make my K5
full-frame when I switch it to movie mode? :)

We are just seeing the overlap of film stuff and digital sensors. So
many lenses were designed for the 35 mm format. We still use "medium
format" even though the sensor isn't that size. Look at the 645D.
The sensor isn't even close to 6 x4.5, but it was based on that body
design. It will take years (if ever) for a more rational terminology
to emerge, but as JCO points out we all know what it means.
History-laden terminology has a certain charm for many and, it seems,
especially photographers.
I plan to start calling APS-C "the happy format" and see if it catches on.

no, the way the term "full frame" is actually
used in todays nomenclature is 24x36 sensor
and lenses. You can mean it to whatever you
want but its not anything but 24x36 at this
point in time technology wise. BTW, I want
Pentax to do a FF dslr, do you know what I
mean? I think you do.

"Full frame" is a bit of silliness. It's irrelevant. Is a 645 camera
"double
frame?" There are many sensor sizes. All of them are full. Paul On Dec 19,

In my opinion, the modern DSLR usage of the term "full frame" means
cameras and lenses designed for 24x36mm sensors. It doesn't mean all
the various formats out there are full frame just because the lens
fits and covers whatever non 24x36mm frame size is being used. Pentax
DA lenses are not "full frame" lenses in the context of todays gear.

Then why worry about the lens frame? A lens designed for APS-C will
outperform one designed for 24 x 36. (They're both full frame. Just
different frames.) Paul
I opine (may be wrong, but that's my right) that some 24x36 designed
lenses outperform some 18x24 ones. In particular, some Sigma EX 24x36
lenses show impressive degree of correction of geometric distortions.
For my kind of shooting it makes them particularly attractive given
their price tag.
You're however absolutely right that there are no "partial" frame
lenses
here. Unless of course, we're speaking of circular fish eyes /grin/.
