For a four-physical-drive setup, I'd suggest:

 o  One drive for OS and software (read once at process startup)

 o  One drive for OS swap file (and data backups, etc.)

 o  One dedicated for photoshop scratch space

 o  One (large) drive for image storage.

Sharing one drive for the OS and software installations isn't going
to be a problem; anything there will only get touched once.
In fact I'd even consider putting the photoshop scratch space on the
same physical drive (although on a separate partition) if pushed.
The usage patterns don't overlap all that much; the OS/Software gets
read at process initialisation time, and the photoshop scratch space
is only used once you've got everything started up and have read in
some image files.

Put the OS swap file & the photoshop scratch disk on separate disk
controllers, though.  That way you can overlap I/O transfers.

I've seen posts here that suggest the refconverter A or M would work.

Neither would really help me, though;  In many of the cases where I'm
trying to get an ankle-height viewpoint I wouldn't be able to kneel
down to look through a refconverter.  (Kneeling down in front of a
race car making a pitstop is frowned upon by race officials :-)

The nice thing about the LCD viewfinder is that you can see it from
several feet away, at least well enough to check overall framing.
An LX with a waist-level finder would work there, but not when I'm
holding the camera at arm's length and poking it round the edge of
the Jersey barrier or catch fencing.


On a totally unrelated note:  I happened to be watching a 30-year-old
TV show the other day (Lord Peter Wimsey: Murder Must Advertise), and
couldn't help noticing just how bad the distortion was on the cameras
of the day!  Barrel distortion on the wide-angle shots, and pincushion
on the others.  Zoom lens technology has since made amazing strides.
(100x or better zoom ratios, anyone?)

I'd guess that your new hard disk has a faster sustained throughput rate;
either a faster rotational speed, or higher capacity per cylinder, than
your original disk.
Although an ATA 133 disk can transfer burst data faster than an ATA 100
disk, that only works while the disk cache is providing the data. Image
files are far too large for that, so transfer at the throughput rate of
the actual disk hardware, which is directly proportional to rotational
speed.  I'd suggest you do the calculations for your hardware before you
consider updating the motherboard - you may find that even ATA 66 is fast
enough to keep up with your disks.




Re: Used DSLR prices

2004-01-14 Thread Shel Belinkoff
Agreed, but not everyone can get more memory into older machines.  I can
only get 768mb into my P3 (have 512 at present), and now that I'm
starting to work with larger files, the extra scratch space is very
welcome.  I'll probably add a little more memory when I can get around
to it.

True enough - swiveling screens are a big plus in certain situations.  My

If you have to swap to disk, then putting the Photoshop scratch space
on a different physical drive takes some of the pain away.  But it's
far better to have enough memory in the first place, and never going
to disk at all.  Even the fastest disk transfer speed is still much
slower than main memory speeds.  Try to get more memory first; a second

Hi Steven,

   this would interest me as well! It would be interesting to know
   somebody with an early kodak DSLR! I will try to ask at local
   agencies how their first Nikon D1 were doing now.

   I think there are few things to look out in aging:

   1) colour dyes. Change over time AND change with exposure to light.
   I really don't know what the mosaic colour filters are made of,
   although Kodak might have revealed it in one of their technical
   PDFs.

   2) the "transistors" themselves in the CCD/CMOS. In analogy to
   computers, whose CPUs can develop something like hotspots over time (especially if
   overclocked or ran at higher voltages). These hotspots are areas of
   worse conductivity? I am not an expert, and it's been a while since
   I read that article. So the imaging chip itself could age as well,
   with hard usage.

   3) the chips responsible for the image processing and other
   "computer" tasks - well, the first computerised cameras (AE1?,T90, F4,
   even LX has some little chips inside, no?) are still working, so
   this shouldn't be much of a problem if they are designed properly.

   4) the other things are just the same as in film cameras - shutter,
   AF, ...

If somebody with more technical expertise knows about the first two
points, tell us please! When things get more comlex, just more bad can
happen... I want a Luddite digital!!! :)

Re: Used DSLR prices

2004-01-14 Thread bucky
Tom,

I agree with you in certain respects.  In particular, I agree that DSLRs will 
not last forever, and will probably not have the lifespan of, say, an MX or 
your Crown Graphic.

My point (and the one that Mr. Desjardins is also making, I think) is that if 
you look at the sole tangible product of a camera - a picture - there is a 
certain level of quality, a combination of objective and subjective factors, 
that, once reached, will not go away until the camera fails utterly.  

This is the issue which JCO raised and with which I quarrel - takes the 
position that build quality is irrelevant for a digital camera because they 
have the approximate lifespan of a nematode, something I simply reject.  I 
expect my *istD to last me for many years, first as a primary body, perhaps 
later as a back-up.

As someone else pointed out, new technology is nice to use, which is why I kept 
Z1ps as well as LXs on the go at the same time.  If Pentax brings out a new 
DSLR with substantially improved image quality (nothing else would be enough to 
coax me), I'll probably buy it.

begin really OT editorial part---

I'm still a little miffed at Pentax for being so slow - I bought a P&S because 
I got tired of waiting for Pentax to get their shit together and give me a 
digital product that I could use my lenses with.  The P&S produces amazing 
pictures, no doubt about it, but the motor skills involved in getting the most 
out of it are entirely different and I found that I had to alter my shooting 
habits substantially to get good results. Also, I can't seem to think 
photographically without me eye to a proper eyecup - looking at a screen 
doesn't seem to work well for me.  Add to that the fact that you're stuck with 
a narrow range of focal lengths, and it just doesn't tally to a good tool for 
my needs. 

It's not that I didn't like film, but that I simply have not got the time 
anymore to shoot, process, scan, catalogue and photoshop slides, with the 
result that my shooting trailed off to a trickle in the several months leading 
up to the *ist-D's release.  Digital fits my needs and my time constraints so 
much better that I am willing to out up with the difficulties - for me, they 
are far outweighed by the benefits. 

If Pentax had waited much longer, you'd have seen a whack of Pentax FA* glass 
for sale on eBay and I'd be gone to Canon.

Re: Used DSLR prices

2004-01-14 Thread Boris Liberman
Hi!

Bucky, I am afraid I either misread his post or language barrier 
played yet another joke on me.

All of what you say is true, but the fact remains that the original poster
was talking about a given model of DSLR being rendered *obsolete*, not
merely somewhat less attractive,  by new models.  His point was that DSLRs
are essentially throwaway cameras because of the rapid march of technology,
and hence the purchaser shouldn't worry about build quality.
It is highly illogical (or should I say, silly ) to render a 
technology throw-away no matter how aged it is. E.g. I use Visor 
Platinum (circa 2000) which is very old, probably even ancient in 
modern PDA world. But it does *all* I want it to do at the moment. 
When it would be something that it cannot do that I must have, I will 
replace it. Or of course it could totally break before that. Then I 
will be forced to replace it.

My ME Super is not obsolete. It is very old and very unattractive for 
some people. But it is my main camera while ZX-L being a backup or a 
body which I take if I have to have AF.

Anyway, back to the chase ... DSLRs are not throwaway cameras 
unless it would be discovered that for some technical reason their 
sensor or shutter cannot work more than given amout of time, say 3 
years. Then of course, it would be plain stupid to buy DSLR if it is 
known that it was used for 3 years. This by they way was my concern 
some messages ago. It is unclear to me what does it mean "excellent 
condition" DSLR. State of used sensor is something that would seem to 
be difficult to judge.

Nevertheless, I do think that people would change their DSLRs more 
often just because fancier ones and cheaper ones would hit the market. 
Perhaps it will not happen with Pentax but for different reasons 
...

Ultimately, I think we reached the point that you and I agree on our 
opinions. It is time to move on to next discussion .

Boris

You are aware that you are talking to a guy whose favorite picture taker is a

OTOH you are right, the problem with using the old laptop is it won't run newer

longer available such as a 116 Kodak folder. So they do compare.

Digital cameras are electronic devices. Electronic devices have historically 
gotten better and better, and cheaper and cheaper. The laws of physics say that 
can not go on forever. But it is going to be awhile until we reach that point.

Basically, a DSLR only has a usable lifetime until it is no longer supported 
with parts, service, and software upgrades. That is also analogic to computers.

They will probably be viable until they are about 5 generations old, but will be 
crippled compared to new ones from about 3 generations (meaning the model after 
next). Compare that to the Canon D30 v. D60 v. 10D.  Next gen. the D30 will be 
so obsolete that only diehards won't want replace it. Yes a 3mp image will still 
be usable, but there are a lot of things besides resolution involved here. Such 
things as repairs, speed, noise, newer storage devices, etc. will become problems.

All of these fall in the "new toy" category.  If you are the kind of
person that is happy with a 20 yr old film camera, then you can hang on
to a DSLR for a while.  The real difference here (and this is why the
camera companies are so excited about this) is that DSLR's have
something to improve.  The film cameras have long since maxed out on
features and the only real improvements were AF speed.  Now the camera
makers have a hook (resolution) to tempt folks who can spend
$1000-2000/yr on equipment.

I am afraid I have to disagree. Apart from swelling of your friends 
, but really. Consider this - speed of auto focus, complexity of 
flash operation, suitability of matrix metering in wider set of cases 
- all this is basically pure software with very little addition of 
hardware. Let's say, in AF the stronger motor would be good, but 
decision as to where to turn it and when to stop is purely software.

Now, notice, I haven't been talking of anything that belongs to 
digital only. All of the above is valid for film cameras... And 
unfortunately, it *is* software. Hence it requires more memory, faster

processors, better programmers *duh!*, and so on...

Naturally, none of these will change the scene you're shooting or your

potential ability to click the shutter at the right time with the 
right speed at the right aperture for the right film/sensor. 

Cheers!

Hi Boris,

All of what you say is true, but the fact remains that the original poster
was talking about a given model of DSLR being rendered *obsolete*, not
merely somewhat less attractive,  by new models.  His point was that DSLRs
are essentially throwaway cameras because of the rapid march of technology,
and hence the purchaser shouldn't worry about build quality.

RE: Used DSLR prices

2004-01-14 Thread Steve Desjardins
A DSLR is not a PC.  The software doesn't have to change and the job
doesn't change.  Once you have a resolution you find acceptable  (Some
are waiting; I'm happy now) the camera will function until its breaks,
you can't read the cards, or you just want a new toy.  IMHO, the last
factor is what limits the lifetime of the cameras.  It is also equally
true for film cameras, which is why I have five of them.

Because its nicer to use something that is well built than something that
isn't.

I wouldn't want to own my friend's Rebel D because it feels like it is a
cheap peice of crap.

Build quality should also mean better pictures, as the equipment should be
better  calibrated, and able to hold that calibration for a
longer time in the real world.
A cheaply built camera won't take very many bumps before it goes out of
adjustment.
And, some of us actually intend to hold onto equipment for several
generations past the shelf life of the product.

For myself, there are a few things that Pentax can do to improve the DSLR.
If they do make a camera that specs out well enough that I think it is worth
opening my wallet for, then my present digital SLR will become a back up
camera.
At that point, it is nice to know that my back up is a well built camera
that I can depend on, in the event that my other camera fails.

When I was shooting weddings, my front line camera was a K-1000, but I
always had my LX in the bag in case the K-1000 failed.

We are now approaching the point of diminishing returns. DSLRs will have a
longer service life than earlier ones as the resolution is approaching that
of
the taking lenses. Your CPU analogy is poor also as PC purchases are mainly
new
users, there is far less upgrading going on than their used to be. Lets face
it
unless you are a gamer or running out of HD space what would be the
advantage
of pushing up the CPU MHz?

The Nikon D100 has been on the market for a year and a half so far. They
may introduce a successor at PMA next month but it probably won't be
available until summer (which would give the D100 a lifespan of 2 years)
and I'd be very surprised if it turned out to be enough of an
improvement to make D100 owners even consider trading up. It took two
years for the D2h to be replaced.
Heck, the D1x was introduced in the summer of 2001 and hasn't been
superseded yet! Another PMA announcement? Could be, but it still seems
like a healthy lifespan to me. I would expect D1x/D1h-class cameras to
be kept and used by their owners just as long as film cameras.

Just because a camera is only sold for a short period of time doesn't
mean that it has a short functional life.  I'm still using a Sony
DSC-S75 as my P&S camera.  This is a 3.3mp camera that came out around

But those are exactly the areas which do get cheaper over time,
rapidly.

Two years ago even a 1GB CF card or Microdrive was very expensive, and
the 4GB drives hadn't been released.  A 250GB hard drive (and a DVD
writer) would have cost more than my entire desktop system.

In another year or so CF card size will have increased by another
factor
of 4 (at constant price), hard drives will be bigger, and in-camera

That 8 (or, more likely, 10) MP camera will buffer more images, and

Cost isn't the big issue. Power consumption is one and the limited
improvement in image quality going from 6 to 8 megapixels is another. I
don't expect to see 10 megapixels in an APS-size DSLR for a couple of
years, and even then only as a result of the ongoing "pixel wars" rather
than any real improvement (bragging rights, in other words). Smaller
pixels will always make more noise than larger pixels and a 1 gig CF
card will always hold more 6 megapixel images than 10 megapixel images.

Right. I expect the trade-up/depreciation statistics for the *ist-D to
be very similar to those of the D-60 or 10D: You simply don't see them
on the used marked.

But those are exactly the areas which do get cheaper over time, rapidly.

Two years ago even a 1GB CF card or Microdrive was very expensive, and
the 4GB drives hadn't been released.  A 250GB hard drive (and a DVD
writer) would have cost more than my entire desktop system.

In another year or so CF card size will have increased by another factor
of 4 (at constant price), hard drives will be bigger, and in-camera
buffers will be larger.  The in-camera processor will be faster, too.
That 8 (or, more likely, 10) MP camera will buffer more images, and
process them faster, than the *ist-D does today.

One other thing to consider for us current owners:
I would really like a backup DSLR at some point.  If/when a better
body is released, I would be more inclined to keep the *istD as the
backup and then purchase the new body, rather than unload the old
body.

Also, there would need to be a significant improvement (more than
Canon D60 to 10D) to make me consider buying it (aside from needing/wanting
a backup body).  Something like a FF sensor.

The point is that the *ist-D *wouldn't* depreciate much if no one was
willing to sell theirs off to buy a replacement. And clearly most people
(correctly, in my view) don't see a *major* improvement coming for a
couple of years. I think the next one or two DSLRs will be less
expensive cameras. The next step *up* will probably not be big enough to
get *ist-D owners to feel the need to move up.

If such a camera came out the *ist D would probably be worth $500 or
less.  At that point I would probably keep it as a second body.

I'm already wishing that I had a second body as a backup, but not
enough to spend $1350 on purchasing one.

I too have made a hefty 'paper' loss, if you look at selling it right now -
but that was never the plan from the outset, so it is a non argument. I
jumped onto the digital scene, because the *ist D provides an image quality
I can live with now and years down the road. The only question I have is
wondering if the digital cameras will endure as long as my film cameras.
Pretty much like computers, you know that your latest machine will be old
stuff in two years time and to keep up to date (if such is your thing) you
know that you will be putting your hand in your pocket, to bridge the
plummeting value of your old equipment.

The real mystery is who buys new cameras (film or digital) and sells them
months later. I know lots of people who have cameras but have had them
years.

Yes, but for different reasons than D60 owners.

Seen and touched, but not used.  Back in the day, I was about to switch
brands to Sigma because they offered a ton of features in their SLRs for a
good price.  I'm glad I didn't because I never would have "met" you clowns!

A LN- goes for $1079.  This is pretty high by comparison to current new
prices.  Although I don't look at the digital section regularly (as
opposed to Pentax lenses, for example ;-) I suspect that there just
aren't a lot available.  That D30 is already gone.  In a few years,
there could be more DSLR bodies available.  OTOH, E10 and E20's are
still commanding more than I would have thought.
