The Olympus C-4000 4MP has a wonderful Macro feature going to about one inch
to take a shot of a bee. The C4040 4.1 MP, suposedly a super set of the
C-4000 does not have that super Macro and begins near 8". The new C5050
5MPhowever is outfited with that macro of near 1".
So either I seek the C4000 4MP or the C5050 at 5MP.
What other cameras have such a Macro near 1" ?

This News group seems very focused near the 3MP. I have read all your posts
comparing te A40/A60/A70 With te Nikon 2100/3100 looked at the pictures, but
have no such input for the C4000 Olympus nor any for the C5050 to see if I
would ever need such resolutions of 4MP/5MP and the expense of them.
I will not be printing out my pictures, I do not even have a color printer
for now. Maybe my sister or GFs will. But I am an audiophile and the love of
defenition at times gets the best of me. I am not a photographer , I once
owned Canon AE1, the Canon Electro and The canon F1 (F1 was ten top of the
line) with a range of lenses from 28 to 300 telephoto, I took many pictures
then but hardly any I treasured opr that were artistically valid.
So with Digital imediacy and chep picture taking I could learn to shoot and
posibly make artistically valid shots.

I welcome suggestions beands and models to look at and consider. And the
advice of where to limit the quality persuits (weakness) I or many of you
may have :).
What to do what to do....hmmmmm

Many (all?) models in the CoolPix line have 4cm or less in macro mode.

It's probably just a result of the depth of the average consumers
pocket-book. Both the 4040 and the 5050 are excellent cameras I will
buy a 5050 soon I think to add to my collection. Don't be put off by
the working range of a camera's macro mode which in the 4040 is 0.2 - 0.8 m
but rather focus your attention of the level of magnification it is
capable of. I would much rather have a working range of a foot or more
if I could still get the same magnification as a macro engeneered to
operate at minute distances.

As far as the expense and usefulness of a 5MP unit I guess you alone
can answer that. What will you be using the camera for? etc.

Someone should make a FAQ if there isn't one already, of the "ideal"
features to look for in a digital camera. Like:

The ability to go manual in as many aspects as possible.
The ability to store and transfer uncompressed images.
The ability to add attachements (PC, Hotshoe, Tripod mount, lens filters, etc.)
Readable LCD menus
Tilt/Rotate/Swivel LCD Pannels.
All glass (coated) lens elements.
Other than plastic body frame,
USB or Serial Camera Control via computer or etc. (other than downloading)
Etc.
Etc.
Etc.


And thier _simple_ respective explaination. Like:

USB/Ser. Cam. Control -- Will allow you to to create ultra hi res stop motion
and time-laps motion sequences.

Non-Plastic Cam Body -- Will save you a trip to the repair shop if you drop
the thing.

Etc.
Etc.
Etc.

Anyone know of a faq like that?

Since the cameras being discussed have lenses of almost
the same focal lengths and sensors of similar sizes,
the degree of "magnification" will vary depending on the
distance. With film cameras, magnification is the ratio of the
size on film to the size of the object. Since with digital there is
no film, one should define magnification in terms of pixels per
centimeter or pixels per inch of the subject. This will depend
on the distance to the subject, the relative focal length the lens
is set at (relative to the sensor size. For convenience,
digital cameras show an equivalent focal length compared
to 35mm cameras), and the resolution that the camera is set at.

Not that many people shoot uncompressed on consumer level cameras.
The quality difference is hardly noticeable compared with shooting
at low compression(SHG?), yet shooting uncompressed yeilds
files that are much larger, and the much lower number of images
per flash card can be very annoying.

True.. Perhapps I should have specified "lossless" in opposition
to "lossy" compressions, and/or etc. But hey, I was being general.

True. But those not in-the-know may assume USB means Cam Control. Actually,
this technique has been gaining in popularity ever since "The Matrix" introduced
"bullet-time" effects using this technique several years ago. Even tho "Bullet
Time" is a Multi Camera effect.

My Nikon Coolpix 5000 has a 2cm macro which is 3/4 of an inch.
Some sonys are 1cm.

This Nikon is amazing for macro.

Im going to try reversing a Nikon 50/1.8 on it for larger than 1:1 ratio.

Aloha Tesselatoe thnak you for your kind repply and to answer your question
what I will be using The camera for, Macro shots esthetic picture shots of
hawaii moments that I feel awe for. And Since I am an artistic creative
person ideas for use will come when the oportunities present themselve. I am
learning to design web sites possibly if I get good at it I may design them
for others. for now I know I could get by withna 2MP camera except for Macro
work. and I wondered what Cameras out ther do good macrowork other than
olimpus .

I did not have the facts on the macro of the c4040 before me but it seemed
way bigger focal distance, so I went to the below site to compare again

http://www.olympusamerica.com/cpg_section/productcompare/productcompare.asp

Note that the macro focus distance of the C4040 is 7.9" to 31.5" not as
short as you write below, while both the C-4000 and the C5050 have 1" - 8"
in Super Macro and 8" to 31" Macro.

I wish that you were correct in saying "...Don't be put off by the working


range of a camera's macro mode which in the 4040 is 0.2 - 0.8 m but rather

focus your attention of the level of magnification it iscapable of..."

Can you explain the leavel of maginfication that I should focus on I do not
imediatly know what to look for.

I do not have a long tome to decise on the C4040 if by chance Olympus made
an error in teir spec sheet on the C40404 please please inform mr quickly!!!
ICan get the C4040 used for about $399 shipped to me if it is not sold soon.
if the focal distance is what I stated above what is your opinion then?

Tomorrow Sunday I am considering looking into getting a refurbished C5050
from some dealers.
Anyond have experience getting refurbished Digital cameras? Pro...? Con...?

I had to refresh my memory of "focal length" and looked it up:

FOCAL LENGTH

This is the distance (in mm.), in an optical system, from the lens (or
primary mirror) to the point where the telescope is in focus (focal point).
The longer the focal length of the telescope, generally the more power it
has, the larger the image and the smaller the field of view. For example, a
telescope with a focal length of 2000mm has twice the power and half the
field of view of a 1000mm telescope. Most manufacturers specify the focal
length of their various instruments; but, if it is unknown and you know the
focal ratio you can use the following formula to calculate it: focal length
is the aperture (in mm) times the focal ratio. For example, the focal length
of an 8" (203.2mm) aperture with a focal ratio of f/10 would be 203.2 x 10 =
2032mm.

JK How do we apply the above to te C5050 and the C4000 for example? could
you site one you would look at to make a decision with?

Thank you so much for the Nicon comment about great macro.

The salesman at Costco told me he has an C5050 at home and tried using the
Super Macro of 1" to eight 8" and found that he could not get a good
predictable focus and promised to send me the examples he tried With the
super Macro. He said that looking at the display was inacurate in terms of
what he expected and what he got was not predictavle in Super Macro.

He Sugested I lock the focus at some distance and try focussing by moving in
and out untill it is the best focus I can get.

I said: "the 4040 is 0.2 - 0.8 m" 2 tenths of a meter is 20 centimeters.
20 centimeters sure sounds like 7.9 inches to me.

O :-)

first, I guess my expirience is a little wide as I've had exposure to many
different cameras with lenses of varring focal lengths so in lou of what
JK had to say:


"Since the cameras being discussed have lenses of almost
the same focal lengths and sensors of similar sizes, the degree of
"magnification" will vary depending on the distance."

My comment doen't
carry as much weight as it would have if this discussion were open to a widder
range of camera models and lenses. Good call JK!

> Can you explain the leavel of maginfication that I should focus on I do not
> imediatly know what to look for.

Also as JK clarified "magnification" in this sense should be measured in
pixels per inch or pixels per CM. which is correct ofcourse. With this
in mind it's simple math to abstract the "Magnification" based on the
dot-pitch (resolution) of YOUR output device.

Monitors are about 72 dpi (max) etc. etc.

Ya, /maybe/ not what you're looking for (?).

> Tomorrow Sunday I am considering looking into getting a refurbished C5050
> from some dealers.

I briefly looked at the 4040... but played extensivly with the 5050...
So without being able to compare the two models directly I can only
say how impressed I was with the 5050! So impressed infact I'm adding
it to my collection having just bought a 5700 (Nikon) only a few months
ago. But that's me... My wife and kids are thoroughly convinced that
in just a few years the entire family fortune will have been invested in
cameras. Heh! You should see my cam-corder equiptment...

O :-P


> Anyond have experience getting refurbished Digital cameras? Pro...? Con...?

I almost always buy used (from a used SHOP!) and then have them send it off
to the manufacturers for "referbbing" shortly after purchasing on the 3month
(or whatever) warrentee that the shop offers. I /always/ get back a camera
that has been hand tuned, bios upgradded, etc. and so is really better than
new.

Nikon is the best for this and Sony is the worst! But any digital camera
manufacturer who also had some fame in the 35mm SLR sector will probably
be good for this kind of practice.

I like to use diopters with my 5050.
The super macro specifies a focal length of 59mm (equiv to 35mm), has a
very short lens to subject distance of 1 inch and has barrel distortion.
I have a Hoya doublet +10 diopter which gives around 1.4 times the
magnification of the "super macro" at a lens to subject distance of
2 3/8 inches with no distortion. Being a doublet, it has excellent
quality.

Here's a comparison picture.
http://tinyurl.com/7voc

Here's a picture showing the super macro compared to +4 and +2 single
element diopters. That combination equals the magnification of the SM
with a lens to subject distance of 3.2"

To be fair, I did forward him this news group and he may be reading this
thread, he also owned a C4040 for a year and it was damaged at the beach
woth salt water, forcing him to get this C-5050 and he is also employed on
a 2nd Job Where he is designing web pages for one of the major Hotels chain,
with a branch in Hawaii. He is also 6'6" LOL :))

<< Yeah, sounds like pilot error. Working in improper conditions etc.>>

What is the right way to handle that? I plan to download the Manual for then
C-5050 and read up on the solution if any. I will add that he let me play
with the C5050 in the store but I did not know how to take advantage of the
time and after reading the manual and possibly your help here, I will
discover how it shold be done, if indeed it can be fully controlled at that
super micro leavel.

Please forgive my error indeed I just noticed the"m" and that it ws not "cm"
nor "in"
and I stand corrected you are absolutely correct :)
So now I need to understand your additional input on the"...focus your

attention of the level of magnification it iscapable of..."
Could you give an example, Kind Sir? it will then be assimulated quickly,
else I will need to get the manual ( which I still plan to do) read it and
find my way to the correct understanding, od how Super Macro results are
affected by the leavel of magnification.

Charlie,
I tried finding information on "Hoya doublet +10 diopter " in both
google.com and in Lap.com search engins, with zero results. where would I
look to read up on what it is? I went to the 2 links you so kindly provided
and find it a bit over my head ( I do have a BS in Physics and Math 1963
grad) I would love to fully understand, and don't mind additional reading to
fill me in so I can make full use of your valuable input :)

Wow, pretty skillfull conversationalist. You took a few trite remarks and
turned them around to potentiate benefit. Nice! Unfortunately there's no
clear answer. Every shot and lighting condition is different. Usually shots
that close up call for alot of manipulation or even specialized equipment
(ring flash, RM-1 remote, pod, etc.). If set up properly or otherwise proper
conditions exist the same mechanisms {(iESP multi-pattern AF (autofocus)
TTL system (contrast detection), Spot AF, Selective Spot AF, Full Time AF,
and Manual focusing by gauge)} function in super macro mode as they do in
macro and standard focusing ranges. What you use will depend on the subject
and lighting. And actually even "locking the focus and moving the camera"
is a ligitimate practice. I made the remarks that I did because you /seemed/
to be under the impression that was all there was. While working in improperly
light scenes for example, without additional equipment that may be one way to
do it but consider that Olympus c5050 has manual 240 step focusing and a
magnified center view which makes it easier to actually "see" to get the shot
precisely focused even when your DOF is as miniscule as it is in a tight macro
shot. Etc.

Anyway just so you know that not all there is is awkwardly moving the camera
to and from a subject with the focus locked...

Huh? Did you read the full reply or just the top part?

BTW, Super Macro (or zoom for that matter) affects the level of magnification
and not the other way around.

Huh? Am I missing something???

Hi Dick,
B&H has the lens
http://tinyurl.com/fklw
it comes in 49, 52, and 55mm sizes.
It's expensive, $75, but being a doublet it's excellent optically.

http://tinyurl.com/7voc
My pictures just show the relative magnification of a 1 cM square of
graph paper with different diopters, a reversed 50mm lens and the "super
macro" setting of the 5050. The super macro equals around +6 dipoters
magnification, but it has to be a lot closer to the subject since the
camera defaults to 59mm (35mm camera equivalent). When using the
diopters you can use the 5050 lens at 105mm full zoom-in. This gives you
more working distance and also gets rid of the barrel distortion the
lens exhibits in SM mode.

That's true for cameras where the "uncompressed" output format is TIFF.
The files are quite large, yet they're still only 8 bits per colour, and
all you avoid is the JPEG compression artifacts - which may be nearly
invisible.

But cameras with a RAW output format compare considerably better. The
RAW output may be only 50% larger than the best quality JPEG, because
only one colour is stored at each pixel. The data is usually 10 or 12
bits, not 8. And decisions about white balance, contrast, and
sharpening can be deferred to when the images are processed. There's
also some more exposure latitude for salvaging bad exposures.

There are people using cameras like the Canon G series who shoot in raw
pretty much all the time.

Same with my Oly 5050 except in the Winter, then it's too cold to shoot
in the raw.

I read everything once, and even though I commented on one thing, may
things were difficult to vissualize I will need to reread it but I
downloaded the manual and will read that too then try and see why I could
not follow it with step by step images in my mind that youy wished me to
see.

Reread JK's post again.. that might be more clear. I have a tendancy
to ramble on and on.

Or, hey I know.. bring a ruler that has mm on it to the camera shop.
put the camera models to be tested in macro or super macro or whatever
mode and shoot the ruler as close as you can but still in focus. Assumeing
you tested cameras with the same sized LCD and megapixel rating you can
just put the ruler on the picture of the ruler and measure a mm in the pic
or count mm across the pic.

At least that sounds right. O :-)
