Ah okay that makes sense.
The Epson R800 is quite an oldy, it's almost 5 years old now but it still has some features you might like for printing real photos.
The Canon ip4500 & ip4600 have an auto duplex function so you can print on both sides.

I myself have an ip4500 and with the right colour profiles it prints good colours and because the drops are so fine the prints come close to printers with more colours but for real photos I think the Epson R800 would preform better. Don't get me wrong I'm happy with the ip4500, certainly because it has the duplex function for my school reports.
Just look at what you seem fit for you.

Like Cliff say the inkt isn't cheap but the ip4500 does quite long with his inkt I believe.

If you were happy with Epson this might be a good option Epson R800
Or else Canon ip4500 or ip4600 would be good enough maybe, it really depends on what you want and for what price?
Since you said Her business use is the primary function it makes it quite hard to know what you expect from it, at least for me.
The models I name come both with 2 kind of black inkt, one for photo and one for texts.

It's only interesting for EU countries I think, we don't need to pay import taxes and such since the UK is part of that. But your prices has come up quite a bit this month and yes it's still cheaper to buy at your place with postage but the difference is getting so small that it's better to buy at your local shop. If something might be wrong with the item and you need to send it back to get it replace it will be more expensive, only the expensive lenses might be an option to buy in the UK
Btw Chris sends outside the UK and that's the only one I would order from if it's worth it

Welcome Peter.
It's applied for all modes and it's usually useful. It removes hot pixels and such noise that becomes more obvious with long exposures. With astrology you shoot mostly with the same camera setting so you can expect that the noise on longer exposures is the same so if you make one dark image it's enough to remove all the noise but with varied camera settings the noise will vary so you need to make one for almost every shot you make.
Hopefully a firmware update will add the option to putt it off for the ones that need it, I've never putt it off on my K10D though.

It would be great if Pentax would sponsor us with some girls and if they lets us test the DA 15mm Ltd on them, who wouldn't be happy
We must think of something for the girls though... hmmm... does anyone want to strip for them? We can't expect Pentax to also pay for some male strippers right

I thought some better of you British people and post some photos of the real FAB1, the Rolls Royce from the puppet serie and not this Ford imitation. You all even brought up my hopes so high for the Rolls Royce

I always thought it would make sure the contacts and so the lenses is correctly mounted on the camera, at least that's the only thing I can think of that makes a bit of sense

Maybe we should make stickies from the most ask questions, a separet area might also be good but then only the modderators should be able to add a topic or else it would still get a mess.

ah okay, now i get it
Did they make a big version out of it then, I only thought they had a scale model?

I understand your point Pete

looked on the Japnese site and they said this
Slow-Shutter-Speed Noise Reduction

This function is designed to reduce the noise that can occur during extended exposures. In addition to the auto mode, in which the K20D automatically judges whether it should be used, the photographer can also choose, via a custom function, to activate this function every time a slow shutter speed is selected.
So the values varies, it's as simple as that. I don't think you will find a list with endless posible combinations you have.

This is the closest hope of finding information about an off function link

Besides of the obvious things when comparing the 2 link
There is also the comparison of the APS-C vs the Four-Third system.
It's going to depened on what you want to shoot if the one is better over the other.
the plusses of the APS-C against the Four-Third are;
- lenses with a wider angle of view are cheaper
- narrower depth of field (depends on what you want to shoot if it is a plus or not)
- a lower degree of manufacturing accuracy is needed for the lenses
- ISO noise is lower
- viewfinder is bigger (most of the time)

Minusses APS-C vs Four-Third are
- narrow angle lenses are more expensive
- Lenses are most of the time more expensive because there is more material in them and are heavier
- bodies are mostly bigger (but the E3 is bigger and heavier then the K20D though )
- lenses take up more space in your bag

that's what i can come up with but probable someone else can give some more points.

I also just looked at the Olympus lens line up and if you want something fast like the 50mm f/1.4 pentax has you have a problem. The fastest Olympus has is a f/2.0 and hardly any lovely primes
They have some lovely zooms but when you see the price it isn't worth it I think.
The Olympus Zuiko Digital ED 150mm F2 for example is £1,779.00 and if you you want something similar for the pentax regarding angle of view and DOF you need a 188mm f/2.5 so the DA* 200mm f/2.8 comes close to that and that one is £645.00 almost a tirth of the price

looking a bit further;
- Olympus E3 Digital SLR with Olympus 14-54mm Lens £1,399.00
- Pentax K20D Digital SLR Camera with Pentax DA* 16-50mm and DA* 50-135 Lenses £1,489.00 - £125 = £1,364.00
that is quite a no brainer for me to be honest
