I completely agree that the human brain "creates" images. BUT lenses are
still necessary to "reproduce" the reality. Hence, the original poster made
exactly the point that it's finally up to the lens which determines the
optical quality and not the camera. I would prefer to spend big bucks on
many top lenses than on cameras and recommend it to everybody who can't
afford both at the same time. If you have 10 cameras and 1 lens you will see
the limit of possibilities whereas with 10 lenses and 1 camera ... unlimited!

Subject: Best Nikon for forest research projects?

First, thanks to all of you who contribute to this digest; 
I recently subscribed and I have been reading the archives 
as time permits and I have found a wealth of useful 
information.  Second, I have a question regarding the best 
Nikon SLR for use by my field research crews.  I am a 
forest ecologist studying the temperate rainforests of 
southeast Alaska and I need rugged (Nikon!), reliable, and 
reasonably lightweight photo gear to document site 
conditions, often under dense forest cover.  The cameras 
should be reasonably moisture resistant, easy to operate 
for beginners, yet capable of producing pro-quality images 
on 35mm slide film.  Built-in flash would be useful and 
matrix metering would help with tricky light-and-shadow 
patterns in the forest.  I tried a 'point & shoot' camera 
(Olympus Infinity Zoom) and was terribly disappointed with 
the results.  The F4s and FM are what I use for my 
personal shooting, but I think the N90, N70, or N50 -- 
paired with a moderately fast zoom lens (wide angle to 
medium telephoto) -- would be a better outfit for use by 
my photographically-challenged crew.  Any comments?  I'm 
especially interested in anyone's experience with these 
cameras under similar weather conditions (cool and wet).  
Also, which lens would be suitable?.  Thanks.

Subject: Re: Zoom or Fixed Focal - Quality

From: XIANGLONG YUAN <yuanx@bigvax.alfred.edu>
Which way to go if I want optical quality? Is it really true that fixed
focal lens are better in optic than zooms provided the similar price
range? some1 said that nowadays the difference betw them is not very
obvious?

Assuming a similar price range I believe that fixed focals are still
slightly better (especially when used wide open) than zooms. It's just
easier to correct all optical errors for one focal length! But indeed
differences have become very small. Lenses like the 20-35/2.8 and
80-200/2.8D are really very close to fixed focals and I don't hesitate to
use them at f/2.8! But they cost a hell.

If you buy a 20/2.8, 24/2.8, 28/2.8 and 35/2 you still pay less than for the
20-35/2.8 and get the extra f-stop at 35mm!

Subject: Nikon F4 modifications

I am aware of 4 minor modifications (re-engineering) of the F4:

1) the switch for metering modes to avoid mistakenly changes

2) some strengthening of the metal body

3) finder has double security to be removed - you need to press the release
button until finder is 3/4 off

4) Also the finder now has an extra hole in the hot shoe for the security pin
off the SB25 etc. flash unit.

5) Mr. Shuuji OKABE  bought a NIKON F4 and its number is 2562408.
He bought it in the first week of Octber 1995.

Just for the record, I've an N90s and it hasn't died on me once. Bought it
when it first came out, and I'm using lithium AAs in it. I've only put
about 30 rolls through it in the half year that I've had it, but it hasn't
done anything it shouldn't do; not even the stuff that the initial batch
is supposed to do (show a low battery indication even when the battery
level is not low). Who knows, maybe my camera is the odd case instead of
those who have had problems :).

The AF-D 28mm/2.8 is a new optical design and also provides CRC - it should

Consider the AF-D 24mm/2.8 as one of the sharpest Nikon wide angles!

Subject: Nikon pola filter

Hello,

I just bought a Nikon pola filter for my 24 mm AF Sigma lens (on an 
F-801).  It is the special one for wide angle lenses (front is much wider 
than 52 mm), but it is a LINEAR one.
Can anybody explain me if I can expect problems with focussing and/or 
metering ?  Everybody seems to agree that jou MUST use a circular 
polarisation 
filter with AF camera's, but I have been using a cheap linear one for 
a long time and never encountered such problems on any of my slides.
Thanks.

I agree, I looked at all the above options, and decided a new F70 was just too expensive 
for me at my stage in photography. Also I hate the interface!! If Nikon put anything like 
it on the F5 there will be a large scale move to Cannon by the pro's in my eyes. 

Between the F801 and the F601, the 801 was a little sturdier, 1/250 flash sync (i dont 
really need, prefer avail light photog anyway) and better autofocus (IMHO)were the 801 
advantages, with the lack of onboard flash counting against it (i do use it at parties). 
Im sure the 801 has other majors advantages, but i cant remember now. Anyway, the final 
diciding factor was a deal I came across in a shop, on on-behalf sale of:
F-601, 70-210D f4~5.6, 35-70 3.3~4.5? + 50 f1.8 all in MINT!!!! condition for $1050 kiwi 
dollars. I figured I could always hock the body if I didnt like it without losing any 
money, but I wouldnt part with it now. 

Mind you, Im not overly fussed with the slow/picky autofocus and I havent really had a 
lot of success with the matrix mode. Do any pros use matrix metering if they have the 
time to work on a shot. It is good for that snapshot type situation though.

The serial number story with F2 cameras will get you close to knowing 
when the camera was actually manufactured. Given that they could have 
started a serial number run a year before the "year" indicated in the 
number and that number series could follow a year afterwards, only means 
that it could get you close.

The serial numbers for current products has no trend. There is no way to 
determine when the product was made by the serial number.

Generally speaking, xx-300mm zooms are pretty good performers but tend to weaken noticeably at 
the 300mm setting, which is probably the lens' most useful setting.  (I own a Tamron 90-300mm 
f/4.5-5.6, and it certainly exhibits this characteristic; the new Tamron 70-300 replacement is 
slightly worse at 300 than mine, the Nikkor is better but the same generalization applies).  If 
you want a 300 and you make 11x14s a lot you may be better with a 300/4 or 300/5.6 prime lens.  
However, my Tamron is really light and handy, focuses quickly and is more than good enough for my 
purposes.

For the record, only the F801S/N8008S was discontinued.  The F601/N6006 is still in production in 
Thailand and is very much part of Nikon's product line.  I own one and agree with you (although I 
prefer my F90).

Point taken, definitely true; however, Nikon doesn't sell photographers so the person asking this 
question is limited to the ability to buy good quality hardware.  Good skills with lousy 
equipment will result in decent to good photographs, but good skills combined with excellent 
hardware will result in better photographs a good portion of the time.  I think he would be 
well-served to buy better lenses, a decent body and practice a lot than buy a Kodak disposable 
and a lot of Nikon School dates.  *grin*

Subject: N90s problem reports

OK, now I'm a little worried too. Just as I'm all set to order my N90s the
list has seen a series of complaints and concerns about this camera.
Whenever I see this kind of thing I can never decides how to interpret it.
Is it a case of:

(a) for every complaint there are many more who have similar problems

OR

(b) we're more likely to hear from people who are having problems than
those who are not.

Any thoughts?

Thanks for your time.

P.S. not everyone has been clear about the kind of problems they've

Subject: TTL with ice, white walls

Timothy Rogers,

Sorry I can't help you with the "D" system, but I can tell you about 
shooting with TTL.  With all the white ice of a skating rink and the 
background of a white wall, your flash on TTL will read all of that white 
and try to expose it as gray, putting out enough light to do just that.  To 
use TTL in that situation, you need to adjust your ASA 1-2 stops to 
compensate.  If you're using 400 speed, try setting your dial around 100 or 
160.  Hope this helps!

Subject: Re: Extension tubes 

Charles,

The books by John Shaw are excellent. He has one specifically for 
closeup photography. He uses mainly Nikon equipment, so you'll get a 
lot of excellent tips from him. One sad thing is that Nikon no longer 
makes the PN-11 extension tube. This would be an excellent extension 
tube for your 300 (it has 52.5mm of extension) because it has a tripod 
socket and a rotating tripod collar. If you find one on the used market 
snap it up!(They may be a few new ones around)

If the filter size on your 105F1.8 is 62mm you might consider the 5T/6T 
closeup lenses (3T/4T for 52mm). The neat thing about these is that you 
don't lose any light like you would with extension tubes, and they 
should get you close enough to get some beautiful closeups of flowers 
and such.

Hope this helps,
Scott D. Burnside

Subject: Re: Nikon vs. Third Party 70mm-300mm zooms

Timothy,

If you're going to blow you images up to 11X14 or bigger you're going 
to want the best quality lens available. That's the Nikon 300 F4.

With that said, another lens you might want to look at is the Tokina 
100-300 F4 AF-D. It's in Tokina's pro line and they are excellent. This 
is a fairly new lens, but the people I've talked to who have seen it 
say it's an excellent lens. There are also rumors about a Nikon 100-300 
F4 AF-D lens.

As for the the lenses in the 75-300 range, I have seen images from the 
Nikon version and have found them to be acceptable. I have also seen 
images from the Sigma and was not as impressed. I have not seen side by 
side comparisons of these lenses, but the Sigma did seem softer. I have 
seen side by side comparisons with the Nikon 300 and the Nikon 75-300. 
There is a difference, the 300 prime is sharper. In addition the 300 
with the TC-14B gives you an outstanding 420 F5.6 lens. The 75-300 gets 
a little hard to focus with a teleconverter, and for me, unacceptably 
slow. But that's mainly because I shoot ASA 50 and 100 speed films 
almost exclusively.

Hope this helps,
Scott D. Burnside

Subject: Re: Portrait Lens Recommendation, etc.

Pedro,

Stick with you first instinct and go with the 105 F2.8 Micro AF-D. The 
105 is considered an excellent focal length for portraits and you can't 
beat the vact that it goes to 1:1 without any help. I have used this 
lens and the 105 F2.8 MF Micro. I loved the manual focus lens because 
it had a solid feel to it, and I found it easier to move the metal 
aperture ring as opposed to the AF plastic aperture ring (I could get 
finer control between f-stops). But, the MF could only get me to 1:2, 
which meant I had to go to extension tubes, closeup filters and 
teleconverters to get to 1:1 (not necessarily all at once, but you get 
the idea).
This lens is great for portraits, although some people complain that it 
may be a bit too sharp for protraits! It's a good focal length, it 
doesn't flatten the subject too much. The only drawback might be in 
tight spaces, you have to move a bit farther away then you would with a 85.

Hope this helps,
Scott D. Burnside

I have owned both the Sigma 70-300mm Apo Macro and the 75-300 Nikkor. Optically there is little discernible difference between the two. Mechanically there is a world of difference. Guess which is miles better and worth every extra penny!

To be serious, the reviews which I have read of all these optics generally place the Nikkor above the others at the 200-300mm end, outside of this range there is little to choose between them. If you are after critical sharpness from any of these optics at 300mm you are probably looking at f/11-16. If you are after quality look at the Nikkor 300 f/4 against the Sigma f/4 Apo Macro. If you intend to use the optic infrequently the Sigma might last the distance.

I can see the difference in quality between my Nikkor zoom at 300/5.6 against my Sigma 400/5.6 prime, the Sigma is just discenably better to the critical eye. If Nikon had an AF 400/5.6 I most probably would have bought that instead for the build quality improvement.

Cheers,

Graeme Scott

P.S. I replaced the Sigma zoom with the Nikkor because the Sigma couldn't focus properly on my F90X at the long end of the zoom, the focussing on the Sigma 400/5.6 is a bit ropey too!
