Subject: Nikon vs. Sigma for 70-210 AF?
Date: 26 Aug 1992 21:18:59 -0700

NNTP-Posting-Host: almaak.usc.edu

What I know --

o       only look at Sigma APO
o       Nikon is $210 or so
o       B&H doesn't seem to carry Sigma 70-210 APO (why?)
o       Sigma 70-210 APO seems to be $240 or so

Generally Nikon > Sigma on optics.  Is that so here?

The only way the Sigma can be costlier is to beat the Nikon
on diaphragm, size, weight.  What is it?

Which do you prefer?

Thanks,

        -ans.

I've missed most of this conversation. Could someone please summarize what  
licensing arrangements has Kodak set up with developers to translate the  
stored images from their proprietary format to other formats?

I understand that PCs and Macs have been targeted by Kodak with their  
development efforts. Any info on UNIX products?

>(the more recent FM2's already use the same shutter as the N8008) and call it the FM3.

I haven't heard of the FM3.  Supposedly it's this specific shutter which
makes the N8008 unable to support mirror lock-up (the F4 seems to use a second
shutter, or something, to overcome the light-leakiness of the 8008's).  Does
this mean the FM3 no longer has pseudo mirror-lockup?  (ie, the mirror locks
up as soon as the self-timer starts, some 10 secs. before the shutter actually
fires).  If the FM2 has sacrificed pseudo mirror lockup for this faster shutter,
I call it a net loss.

Advantages: No mechanical couplings from camera to lens which can fail
          : Potentially faster and quieter focusing (Canon USM lenses)
          : One less camera body component to potentially fail (motor for lens)
          : Able to power big heavy lenses easily
          : If lens motor fails, you loose a lens, if body motor fails you loose
            all lenses (though you can always MF).

Disadvantages: Slightly more expensive lenses (every one has a motor)
             : Slightly heavier lenses 

Note that the new, expensive, fast Nikon Telephotos have followed Canon's
lead and put the motor in the lens.

Just my opinions.......

  You *did* specify cheap, so I'll reiterate something I suggested 
  only a few weeks ago.
  Get a storm window, tape tissue to one side, use it to span a couple
  of chairs (boxes, tables, cinder blocks, what-have-you)
  and set a lamp on the floor underneath.
  You don't have a storm window? Then a spare sheet of glass will do.
  You don't want to use tissue? Then frosted glass or white translucent
  plastic are in order. 
  You want something permanent and equipped with daylight balanced lighting?
  Now it is going to start getting pricy.

This may be true, but if so it doesn't add up to an argument in
favor of the current system of patents for algorithms and/or
data formats.  The current system rewards invention by a grant
of exclusive rights to use the invention.  However, the distribution
problem cited above seems to imply that it is marketing and distribution,
not invention, that is in need of special encouragement and subsidy.
If so, patents should be granted not to the inventors of a technology,
but to whoever can demonstrate that they have the capacity and
commitment to carry out a suitable marketing and distribution campaign.
Or perhaps the distribution problem means that patents are not neccesary
at all, since the high cost of marketing will act as a sufficient
barrier to prevent all be a few companies from entering the market
and each will have a good change to gain sufficient market share
to recover their marketing costs.  The distribution problem you cite
may be a real one, but the a rationale for software patents will
have to sought elsewhere.

Just to make things a little easier, you might try specifying Kodak
Publication J-20, Disposing of Minilab Effluent.  There is also Publication
J-55, Disposal and Treatment of Photographic Effluent -- In Support of Clean
Water, but they will probably want you to pay ($8) for that.

: A quick summation is that you mainly need to watch out for ANY chromate
: disposal and limit your silver (it ties up the oxygen that the good
: beasties need).  Also try and keep the effluent close to neutral pH.

Yeah, the chromate is nasty.  Makes me sneeze just to have the bottle open!
As far as the silver goes, it is a good idea to recover it anyway, considering
that it's a precious natural resource (and if you do it right, you'll get
a little monetary compensation.  I wish I could advise you on that, but I'm
still learning to do it myself.)

What I got out of Pub. J-20 is that it is a good idea to mix all of the
solutions together, and then slowly flush them down the drain with *plenty*
of water.  That advice applies to what they call "Plumbingless Minilabs";
I'm not sure if they mean it to apply to septic systems (what you asked
about) but I guess it couldn't hurt.

What Pub. J-20 *does* say about septic-tank systems is -- after a statement
that your permission is subject to local regulatory approval -- is that
a good septic system can "very effectively" handle *dilute* photo effluent,
even if it constitutes as much as 25% of the waste entering the system;
although less than 1%, added in slowly over 24 hours, is recommended.

I guess what this adds up to is that if you get a large container and put
a small hole in the bottom, you can place this in a sink and turn the water
on, then pour your used solutions into it and let them slowly drip out.

Date: 27 Aug 1992 07:27:10 GMT
Organization: University of Karlsruhe, FRG
Distribution: world
NNTP-Posting-Host: i11s10.ira.uka.de

Hello everybody,

in the September issue of the German `foto magazin' I just
found a short article about the new Nikon F90 and SB-25, 
both to be introduced at the photokina in September.

Here are the details (sorry for my less than perfect English :-)

The F90 is intended to fill the gap between the F801 and the
F4, and will be priced at about 1700 Deutschmarks (the list price of 
an F4 is about 3300 Deutschmarks, if I remember correctly). It's 
`slightly more voluminous' and `a bit more solid' than the F801.
It features a new AF sensor for vertical and horizontal structures
(according to the article a *noticable* improvement), and selection
between to sizes of the AF sensor area.

It uses a new version of the matrix metering system with 8 fields, 
which also uses distance information (objects in the depth-of-field
range (if that is the correct term) is regarded as "more important"
than objects before or behind it). This feature requires the new "D"
lenses to work fully, and is called `3D' martix. Conventional AF
lenses will only work `partly' with this new features (whatever that
means). The first  "D"-lenses, by the way, will be a 2.8/35-70, a
3.5-4.5/28-70, a 2.8/300, a 4/600 and a reworked 2.8/80-200.  The F90
also has a `vari-program-system' with seven programs, (and seven tiny
symbols on the back to show you what they are good for :-) and an
`electronic organizer' which will be available in autumn 93 (sic!,
next year) will make it programmable.

According to the article, it is nevertheless `a typical Nikon', and
Nikon calls it the `predecessor of a new generation (Vorlaeufer einer
neuen Generation, in German)'.

The SB-25 is the first flash with a `TTl-multi-sensor with 
five zones', uses `ultra-short' pre-flashes to analyse the scene,
and works esp. well with the new "D" lenses. It's based on the
SB-24 (LZ 36), has a pre-lash against red eyes, a built-in
miniature reflector for indirect flashes, and a diffusing screen
(Streu-Scheibe, in German) to work with lenses down to 20 mm
focal length. It will be priced at about 600 Deutschmarks.

Hope I didn't miss anything, and please (!) don't ask me any 
questions.

On the other hand, it is not clear that there would be *ANY* games now
if Nintendo had been open.  Remember the early '80s?  Video games were
everywhere.  You almost couldn't walk more than a block without running
into an arcade.  Atari and Mattel had thriving home game systems.  Activision
and Imagic provided quality thrid party games for the Atari and Mattel
machines.

The home game makers were working on really cool systems (e.g., Mattel
was likely to have a 68000 based system with bitblt hardware and high
resolution graphics by 1983 or 1984 -- I was working at the company that
was designing this).

But by 1983, most of the arcades were gone.  Mattel was out of the market.
I don't remember if Atari was still making the VCS or not.  Most of the game
makers were out of business.

A few years later, Nintendo comes along, and recreates the home video game
industry.  I read an article somewhere about how they did this.  It said
that before entering the market, they analyzed the collapse of the previous
market.  They decided that the cause of the collapse was too many low
quality games from fly-by-night game companies.  They determined that the
home video game market could only thrive if game quality was high.  Hence,
they had to make sure that no fly-by-night companies could come in and
start making bad games.

the salesman about the perennial "new Nikon camera" rumor that's been
floating around for the last several months. Instead of getting the usual
"hear no evil, see no evil, speak no evil" answer, I was informed that they
have just received a brochure for the Nikon ND90 (I wonder what was wrong
with 9009. Oh well, those high-priced marketing consultants have to get
paid for something), a camera positioned between the 8008s and F4. It will
reportedly have updated electronic gadgetry a la Minolta and Canon but with
the (relative) heft and sturdiness of the 8008. Unfortunately, it
apparently does not have mirror lock-up, although I would wait for more
detailed product information before conjecturing on other features. Though
no one has clued me in to upcoming developments, it wouldn't surprise me if
Pop Photo has a sneak preview in the next issue or so. Unfortunately, I
have no news yet regarding price or availability.

Macro focussing with a Leica rangefinder (without a reflex housing
I suspect you mean-- just the bare lens). The closest you can come 
to a portrait len with close focussing is the 50 mm dual range
Summicron f2.0. It focusses to 3 feet 4 inches bare; with the "eyes"
accessory, it rangefinder focusses to about 19 inches or 1:7.5.

My 90mm f2.8 Tele-Elmarit focusses to about 1 meter.

The closest compromise is the 65mm f3.5 (Hektor? Elmarit?) which
is a short mount lens requiring a Visoflex reflex housing, which sort
of defeats the purpose of using a rangefinder camera.

You could get closeup lenses and using tests, calibrate them and use
a measuring tape. Then you could have a table converting distances on
the lens mount into working distances with the closeup lens.

The 35mm f2.0 Summicron focusses to about 28 inches, which is sort of
close up, but it's a little wide for a portrait lens.[A[B

Your best be is probably the DR Summicron. It will cover a field of
about 8x10.5 inches at its closest focussing distance of 19 inches.

I've just been at my camera store to pick up some prints. While waiting I
got to see a new Nikon camera - Nikon F90 - introduced last friday; they had
just got it. I don't think it will replace F801s but it will fill the gap
between F801s and F4. It has a very fast AF (I tried it with the 28-70), 
faster than my F801s and it also handels horisontal lines as well as
vertical. It has, as the F801s, matrix, center wighted and spot metering and
the new is multi spot metering just like the old Canon T90. Compared to the 
old F801s it is lighter and looks like a mix of Nikon and Canon!! But I could
recognize the switches from my F801s. The dealer also told me that Nikon 
would come out with a new series of objectives - NO, not with AF-motor inside
but with some new features - he didn't tell me what features. But the mount
is the same as the good old one. Thats all I know from playing with it for 
ten minutes. Oh it will be priced about 30% over the F801s here in Norway!!

You'd be much better off choosing 1) above. Canon has 85mm lenses
at f1.8 and f1.2L, and 100mm lenses at at least 2.0 and 2.8 (the latter
being a 1:1 macro lens of excellent quality).

Of these, I've only used the 85mm/1.2L lens more extensively. It's
expensive and heavy (like the 28-80mm/2.8-4L zoom lens), but its
optical quality is without compromise (well, without significant
compromises at least).

My apartment was recently robbed, and the main thing stolen was

Fortunately, I had replacement value insurance, and now have around
$3000 to spend on replacement equipment.

I am looking for suggestions as to how to spend this money.

I would like a nice P&S camera for mindless-capture-the-moment Kodak
sort of pictures - I was very satifsfied with the Fuji, but I understand
that there might be better ones out there.

I would also like feedback from you F4/Nikon AF owners as to what (AF) 
lenses to buy.  I plan on the F4s and SB-24.  
I was considering the 80-200/2.8 ED, a wide angle fixed or zoom, 
and a normal ( maybe the micro 60 ).

Any advice pro or con on any of the Nikon AF lenses would be greatly appreciated.
