Small DSLRs are limited in one sense, they are not comfortable to hold with
larger lenses. We need compact interchangeable lens cameras (like
Olympus's proposed u4/3rds models) but have to work within their
constraints, which means menu-driven commands and small lenses.

Quite the opposite actually, since with large lenses you (or at least I
and many others) support the lens in one hand by the zoom ring, with the
other hand on the shutter release. That way, the size of the camera
body doesn't make any difference at all. Now, with a small wide angle
prime or pancake lens, both hands are usually on the camera and that can
seem difficult if you aren't used to it.

I used full frame Olympus OM film bodies that were smaller than any of
today's DSLRs (OM-1, OM-2, OM-4, OM-2n, OM4Ti, OM-1n, OM-2SP, OM-3 in
that order of acquisition) with some pretty large lenses for over 30
years without any discomfort at all. With the body being that small,
all your attention was on the lens - the body just needed to "click" on
command.

Of course, Olympus OM cameras had one significant ergonomic advantage
which helped holding the small camera as described, although many
newcomers found it difficult to get used to: the shutter speed control
was around the lens barrel. So all of the exposure functions were
controlled by the lens hand.

I for one, would love a full frame OM sized camera - even one from
Olympus.

i'd love an om-4 digital. that (and it's siblings) are the only
cameras that i know of that implemented spot metering where it was
actually useful.

Far better than looking at it on the screen (even IF you've done a
calibration) is to use the measuring tools in an app such as Photoshop:
do areas that you know should be white (and black) measure that way?
Because if they do, the rest of the picture is probably OK too.

Then, if the printer prints the "white" areas as any other color, the
printer has a problem.

For you who walk around with eyes closed.

"The XL20's LED-based backlighting system is another in a long line of
technology firsts". Read the whole story here:

http://www.samsung.com/au/news/newsRead.do?news_seq=5064&gltype=

Just because a cheap monitor has a light behind the screen to let you
see an image in the dark does not mean it is a "Backlit" monitor.

If idiots who think they know it all bothered to do some research before
dribbling off at the mouth, they might gain a grain of knowledge. It's
hard to imagine your pea brain having enough space to do that Ray, but
at least try occasionally would you?

If you got your head out of your ass for a while and washed your face,
you'd realise you ain't that cool dude with sunnies you thought you were.

that refers to *led* backlighting as opposed to cold cathode
fluorescent tubes.

then what does it mean? front lit?

so not only do you not understand what backlit means, you spew insults
too.

using alternate inks can sometimes be better and it can also be worse.
some inks are more likely to clog the printer, for instance. if you
get quality inks, that probably won't happen, but the colours can be
different since the replacement inks won't be identical to what epson
ships. thus, you will need a new printer profile.

it's very useful and it's not hard to do (or have done).

Yes it does, you cretin. That's what 'backlighting' *means*!

Many times you can get a good estimate without load.

A rechargable is best tested by
a very loooong test.

Thanks, that was very useful as I'm mulling over purchasing a G10 to
complement my SLR.

I'm not sure I'd use DXO, but PTLens and PS4 (both of which I already
own) should do the job perfectly.

Yeah, Mich's expression wasn't the best. I spent a fair bit of time trying
to get the flash and exposure the way I wanted it, and then clicked a few
shots. Mich had been snoozing before I took the picks, and I guess he
wasn't quite awake yet. When my wife got home and told me he looks "sick"
in the pic, I was a bit disappointed, but I'll try again another day when
he's been running around beforehand, so he'll look a bit perkier.

Re: my spelling of colour, I'm actually from Canada. We use the British
spelling -- well, most of us do. The pic of Mich on the bus was taken here,
in Edmonton.

However, my wife is from the northern part of England, Newcastle Upon Tyne
(spelling?). She's told me a lot about the area, and we hope to go back
there and take some pics in the Lake District, Dudley Castle, and some of
the old cathedrals.

Take Care,

Well shit, I don't know. Maybe because anything worth doing is worth

I have an old reflector type telescope and a T-mount adapter for my EOS
Rebel XSi. As soon as it warms up a bit, I'd like to try taking some pics
of the moon, etc, and I'm wondering if using a 2X TC would work with the
scope. Or, will it make the exposure so long motion will be excessive?

Anybody have any experience in such situations?

The moon itself is as bright as a sunny day and exposures are
generally quite short, so I think you may get away with using the 2x
if it fits OK. Depending on your cam and it's noise characteristics,
you also have the availability of using higher ISO to compensate for
the 2x light loss.

Cheers

What focal length and aperture is the scope? What camera are you
using?

Exposure times won't be a problem with the moon. It's very
bright. Well, not at the moment as it's near new, but you know
what I mean :)

Noise doesn't seem to be too bad with the XSi high ISO speeds, so I wouldn't
be afraid to use it. Also, I can switch in the optional high speed noise
reduction routine -- haven't had to use it yet, so I don't know how
effective it is.

Thanks, Rusty, I'll give it a try and see what happens.

As if that means anything.

It really doesn't matter what the frame proportions are within a
reasonable range of 1:1 to about 2:1. Photographs are not supposed to
be stuffed into a restrained proportion anymore than a painting is.

Hasselblad's H series is 645 (film) and most of the digital backs are
4:3 at various actual sensor sizes.

LOL! Well said. I'll go one better, neither one of them has the wit or
entertainment value for any us to waste an attempt on stimulation.

Yep! Even the 700mm isn't big enough for the old poop chute!
