low end digital / low light and macro ?
 
I have a Fuji P&S... nice zoom... and, it does great daytime
pictures... but I have two problems with it.
This camera will not function once the Sun goes down... without
flash, it chokes even on a heavilly overcast day.

So_ next, I'll be looking for a digital with two capabilities...
it needs in reduced lighting situations... and... it needs to
work totally without autofocus, or, maybe I should say, have
a manual focus mode.

What kind of digital... inexpensive please... will have these
capabilities ? Or... has digital completely forgotten about
manual focus and low light ??

thanks for any suggestions. Im sure these same problems
are perplexing a lot of other 35mm/slr people too.

Low end, low light and manual focus are three mutually exclusive
things.

The Fuji F20/30 series were the best of the compacts for low-light -
no recent cameras have done any better. But usable manual focus?
Nup.
On small sensor cameras you just won't get significantly better
results. I'd suggest you forget looking at compacts - if you are
after low cost, about your only option might be a secondhand dslr with
a 50/1.8 lens or similar. The older canon digitals are probably the
best low-light performers.

The inexpensive DSLRs now available work well a much wider range of
conditions than the small-sensor compact cameras, the auto-focus is
significantly faster, and they aren't that heavy either. Worth a look,
at least.

Fuji P&S cameras have sensors that under-perfrom those by many other
companies, hence the need for their cartoon-like noise reduction which
removes all fine detail at high ISOs and in shadows.

You've said that before, but it's still complete BS, at least as a
generalization, and this has been demonstrated in the past. It may
be true for *some* of Fuji's P&S cameras, but definitely not for all
of them, a few of which (such as those mentioned by Mark, above) are
better at high ISOs than any other P&S cameras, much more closely
approaching the detail of DSLRs at high ISOs than any other P&S
cameras. You either ignore facts that you don't like or forget
very easily. It must be distressing that what appears to be one of
your favorite P&S cameras has such poor high ISO, low noise
performance, despite its ultra low read noise, that you so often
tell us about. :)

The day I bought the FZ50, I almost bought the 6MP Fuji (6500, I believe)
which had RAW (I went with the FZ50 because of the legendary lens). It
turns out they both have similar pixel read noise, but the FZ50 collects
more photons in each of its 10M pixels than the 6500 does in each of its
6M. This is the same 6MP sensor in the "legendary" F31.

I'm just stating the facts as I find them. Here's what the 6MP Fuji sensor
looks like at ISO 3200 without any noise reduction:

Sorry, I meant to link to the page, not the image itself:

http://www.pbase.com/jps_photo/image/89156547/original

The page mentions that it is a 100% crop; if that were the entire image
properly downsampled, that would be *really* bad.

Indeed. Like asaar, forgive me if I defer to other sources. Just for a
change from the usual dpreview pages, here are two Cameralabs pages, one
for the F30 and one for the FZ50. Look carefully at the ISO 1600 shots,
taken in controlled, but real-life conditions:

http://www.cameralabs.com/reviews/Fu.../page4ca.shtml
http://www.cameralabs.com/reviews/Pa.../page4ca.shtml

Neither are brilliant, but imo there is more usable detail in the Fuji
images. The pure noise tests on the previous pages are even more
damning, but less 'real'. Similarly, every review I can find for the
FZ50 is critical of its low-light/noise performance, and its
over-zealous NR. Nice camera otherwise, don't get me wrong.

Eg, here are some reviewers comments:
(IR) - Fuji has been wise to emphasize the F30's range of excellent
low-light options...
(CL) - (The F30's) low light capabilities still lead the market
(DPR) - F30 is far and away the best low light compact camera on the
market today... F30's sensor gives you at least a two-stop advantage

(IR) - Panasonic FZ50 really struggles when shooting at higher ISO
levels, producing images that are marred by excessive chroma noise...
(CL) - FZ50 sadly runs into trouble at 200 ISO... detail is smeared-out
by aggressive noise reduction... with its compromised image quality
above 100 ISO is arguably a step-backwards
(DPR) - fantastic camera with a less than stellar sensor... smearing of
detail.. limits the FZ50 to low ISO settings.. only for those users who
can live without anything over ISO 200...

And there are numerous other examples - are all these people on the Fuji
payroll? It seems you may be justifying your own purchase decision,
rather than doing controlled tests. If you wish to show two identically
lit and exposed images, and a similarly lit and (under)exposed
unprocessed shot at 3200 from the FZ50... feel free to come back and
continue the discussion.

I'm intrigued by your claim that FZ50 'collects more photons' - do you
have a source?

Anyway, this is rather offtopic as no *compact* camera is highly suited
to low-light photography, and the FZ50 is neither compact or worthy of
any consideration for someone who is focussed on low-light imaging...

Do you have alternative suggestions for the best *compact* camera, and
supporting links?

OK so far.

How so? The FZ50 has a 1/1.8" sensor and the S6000/S6500 has a
larger 1/1.7" sensor. If the larger sensor has fewer pixels, then
those pixels/sensels must be much larger than those in the FZ50's
sensor. Unless each of the Fuji's sensels is really tiny, and each
one is surrounded by a lot of unused, wasted space.

Legendary it may be, but it's not the camera that DPReview
compared in its "legendary" high ISO/low noise comparison. That one
was the F30, but close enough. At least for the moment you've
abandoned your familiar "cartoon-like noise reduction" rant, which
you've used before when you didn't want to admit that the F30 could
possibly have low noise at high ISO as well as more detail than all
but the DSLR in DPReview's test. Now if you're really on to
something with your claim that the FZ50's pixels/sensels capture
more photons than the Fuji's, it should outperform the Fuji. Let's
see if DPReview found this to be true (selected quote snippets) :

Oh well, at least your FZ50 has low read noise. Unfortunately,
when it comes to high ISO/low noise with high detail, it doesn't
come close to the performance of the S6000/S6500, which in turn is
bested by the palm-sized F30. If your FZ50 could produce the same
"cartoon-like noise reduction" you'd be ecstatic! :)


For those that never saw DPReview's Compact Camera/High ISO test
(and possibly for you, who apparently wants to forget it), it's
still online. Cameras evaluated were Fuji's F30, Canon's Powershot
S3 IS, the Panasonic FX01, Sony DSC-H5, Samsung NV7 OPS, Ricoh
GR-Digital, Olympus Mju 800, Casio EX-Z850, Canon Powershot G7,
Panasonic LX2, Olympus Mju 750, Casio EX-Z1000, and finally, your
Panasonic FZ50. Canon's EOS 30D was also included in the test, and
DPReview's reason was that it "is simply here as a benchmark to
compare the compacts to".

http://www.dpreview.com/articles/com...hiso/page3.asp


On second thought, it'll probably be a waste of your time unless
you've changed (become more open minded) since you posted this
comment about DPReview's comparison article nearly a year ago :
