Regards[/quote]I would just say users error, you just need to know when the press the button
But honestly though you can't prove the photo is out of focus because of slow AF neither can I that it was user error.
Then again Daniel did manage to capture these... link[/quote]I do agree but if the setting is AF release, you stand a chance. Either way, my latest input of macro/close up shots are all MF so AF speed and its related issues are irrelevant. The only whine going on is the lack of a comparable AF speed to other systems. I also wish that Pentax had a fast AF system, the fact is they presently don't, so if you do need that function, buy a system that does have it. I did not buy into Nikon for fast AF, I did so for FF and the low noise high ISO qualities.
I only have my K7 with me plus lenses because its easy to travel with and produces the results (if I get my settings right). It's horses for courses and no amount of discussion will sort that out. The Pentax system is a truly wonderful system but it does not perform in certain areas. If it did, it would be the only system in use or for that matter any other make that did it all.

Not quite true that a decent load is required, as a constant voltage output power supply will hold the required voltage whilst within its current output capacity. Constant current chargers will have a headroom voltage high enough to keep a constant current flowing through a load and regulator circuit. If that load is a battery who's voltage will rise, the differential voltage will decrease as the battery voltage rises. The headroom or source voltage will be selected at a value that maintains the constant current into a fully charged battery.Any charger (or power supply for that matter) needs a decent load to show the correct output voltage.

I agree that you are correct in terms of unregulated circuits.
In the case of the Pentax chargers, the battery does provide the load and capacitance to stabilise the circuit.

My first AF camera was an Olympus IS3000 with a 35-180 inbuilt zoom. Superb piece of kit that recorded several years worth of images of family life.
The next AF was my Minolta Maxum 7. I thought long and hard about buying it against the Pentax MZS, the advertising and the huge digital screen on the rear won the day.
I then bought an MZS followed by my istD, Maxum 7D, K10D, Nikon D700 and my K7.
I still have them all.
I have not included point and shoot cameras of which there are a good few in my cupboards.
What was your route?

Nothing wrong with video for those that will use it on a DSLRV. I won't and would rather have the money or circuitry it requires on other camera improvements. Its horses for courses. My K7 has not been set to video and I doubt it will be.
I have done video and used a Canon XL2. After all, it is a video camera.

excelent, now, who can read Japanese?
Yves link takes you to a page which says:
"Challenge the next Dream
Super high resolution(?) image the world with a big image sensor. This real ability will be revealed with the CP plus"
Not very interesting I know - but try this page
www.camera-pentax.jp/new/news01/index.html
link
This page reads:
"In this new product, comparing with 35mm full size it has about 1.7 times more pixels(?)
From one image the data amount is 100MB - you can understand the impressive image quality of the big sensor by just one look at it."
(?) means there was a technical word the missus didn't fully understand herself.
Don't know if any of this will give any clues or not - but there you go.

Hmmmm?
