I think that a lot of what he is going through is what Pentaxians
would/will be going through if/when Pentax ever offers a full frame
camera. You don't really realize how much you are taking advantage of
(relying on) the 1.5x focal length factor (actually equiv. FOV) of the
APS-C until you try to replicate your lenses on a full frame system.
To try to find lenses that still give you that focal length and
maximum aperture becomes an expensive proposition, when it is possible
at all.
Extreme example: DA* 200mm f2.8 can be bought for under $1K. (More
like $700, used) 300mm equiv. FOV on APS-C
Move to a full frame, now you need a 300mm f2.8 to replicate that FOV.
Not really, if the full-frame camera gets an equivalent pixel density to the
APS-C one(s). You might then use the 200mm as before, and crop by 1.5x in post
processing, and get exactly the same result...

Price one of those lately? A Sigma is $3400. A more reasonable choice
would be a 300mm f4. You've replicated the FOV, but lost a full stop
of light.
