Pentax probaby wont support aperture rings on this new FF body to help
keep it cost competitive, but once they get a few FF bodies under their
belt, there's always the possibility of supporting the rings later on a
top line model. ??

Now Nikon at the top end supports their "aperture simulator" well at
least one of them. Pentax could make theirs work more easily, they
don't have the issue where a "K" mount lens of the wrong series
mounted on a "K" mount body might actually damage the Lens or Body.
Fuji has developed an entire series of new lenses that have *gasp*
aperture rings, that photographers even new photographers, who have
never shot film, think are the cat's meow, (yes, I chose that
particular superlative for a reason), and find extremely intuitive,
something a lot of us have known for years and never forgot.
It would be relatively trivial for Pentax to support the aperture ring
on all legacy lenses that have one.
However I'm not making a point about any of that. I'm just pointing
out that if you need a whole new lens suite when moving up to a new
body, there is no rational reason to stick with the old system.
Rationally you should pick the system that offers the most cost
effective solution. Unfortunately that's not likely to be Pentax.
It's not that I have no interest in buying new lenses. There are
budgetary issues, and I have a full Pentax K mount range consisting of
K, (and M), A, F and FA lenses from 17mm (Fisheye) to 300mm), with a
few Classic Vivitar Series 1, (and a couple of oddballs that defy
description), mixed in. I bought the best I could at the time. They
were an investment in the best quality I could afford.
Thirty year old lenses are pretty good. If you don't pixel peep but
print out images at 300 DPI you will find that 30 year old lenses hold
up pretty well. I've got a couple of images of a Hawk taken with an
A*300 F4.0 and F 1.7X where the lens and TC pretty much out preform
the sensor, (K20D). That's a 30 year old lens that's pretty much a
mount update of a 35 year old lens design. For all practical purposes,
while the later * 300 lenses may be marginally better, in a 250 DPI or
300 DPI print, or for that matter reasonable screen resolution, not
pixel peeping, (because God knows at a 400% view), you can find
defects in anything, it's as good as you need.
My final word, (quoted by many, so I don't know who to attribute it
to), "you date cameras. you marry lenses", if I've got to divorce my
lenses, I won't necessarily, in fact probably won't marry back into
the same family. There's only so much of any kind of abuse I can
take. I'll look for a different kind of abuse, at least it will be
different.

Really, since Pentax won't offer better aperture ring support for K and
M series lenses, then I don't really see any particular reason to go
full frame. To get the most out of the camera I would have to invest in
a whole new lens kit, Might as well switch to Nikon or Canon, in
that case.
I'm getting a bit tired of the aperture ring simulator bollocks.
Unless I am vastly mistaken, the presence of an aperture ring
simulator does absolutely nothing to the optical path of the lens.
The only functional difference that you would get is whether you have
automatic or manual exposure.
In my experience, for about maybe 5-10% of the photos I take, the
light situation is changing rapidly enough that while I am shooting
action shots, automatic exposure gives me better results than manual.
If all of your photography is sports photography, outdoors, in
changing light, then I can see that having automatic exposure can
make a significant difference.
In other situations, I find that about 30% of the time, automatic
exposure will work well enough that thanks to the exposure latitude
of the sensors, for any but my most critical shots, I wouldn't notice
the difference between automatic and manual exposure. The vast
majority of the time, I find that the metering on my camera is either
wonky enough, or tuned for a different style of photography than
mine, and automatic exposure simply does not work as well as manual.
I do find it slightly reassuring that at least in these cases I'm
smarter than a $20 microprocessor.
You have professed that you have no interest in buying new lenses. In
reality this means that you are not a customer that Ricoh should
worry nearly as much about as the person who will buy $10,000 worth
of glass to go with their $2,000 camera body.
I will argue however, that even in a static setting, with manual
exposure, or bracketing, taking the very best care, you will still
not get as sharp of images with thirty year old lenses as you will
with the best of today's lenses. Optical science and production has
not been static since you bought your lenses. The best of todays
lenses will outperform the best lenses of the manual exposure era.
Maybe not in every condition, but there is a reason for coatings,
there is a reason that they keep improving their coating
formulations. Also computer design allows them to do more to optimize
the performance of their lenses.
I have a simple reason for wanting a full frame body, and that is
that it will effectively give me a whole bunch of new lenses. My 31
goes from being a standard to a wide. My 50/1.4 goes from being too
long for most indoors work, to about right. My 20/1.8, despite it's
flaws, will become a rather interestingly wide fast lens. In cases
where I currently use my 50/1.4 stopped down a bit, I can use my
77/1.8 with its magic pixie dust.
Rather than whining about the aperture simulator, it would be a lot
more productive to ask for a pony.
