Not everything such as using the build-in flash to trigger the flash gun wireless but the exceptions are written in the explanations.

To start it only work on the newer Metz guns (except 36 AF-4) and it's a mode on the gun itself.
If you set the gun on HSS it should allow your camera to use faster shutterspeeds, don't know if there is any camera mode restrictions though, don't believe so besides that you can't use it in X-snyc mode and B

Here is a good guide for you link

Sorry to disappoint you but it also works on the K100D I believe, if you have the right flash that is.

It's so far as I know only very useful as filling flash, besides that I don't know any use of it.
If you want to freeze something you're better off using the flash normally instead of using HSS since a single flash freeze the image but with HSS it "strobes" so it won't stop movement.

Looking for a potential set-up for a new computer but don't know really what to get at the moment.

It's main use will be photographic editing but also the occasional games and the PC will be running Windows 7 64bit since I'm running the RTM now and it works great.

The two major problems at the moment is what CPU and GPU to get.

CPU will be Intel but which one?
i7 with triple lain, with dual lain or an i5?

GPU is also a hard one.
I'm quite impress with the new ATI cards (RV770-gpu) although somehow Nvidia always seem to be the deal when working with Adobe in terms of compatibility.
Is this true or is their hardly any difference?
I've always liked Nvidia cards but recently they seem to lag a bit behind ATI at the moment and ATI are impressive in terms of games and performance/power consumption so might go for them if there are no drawbacks.

Why not use raw instead?

£5000-£6000 would be a very competitive price, it might press down some of the high-end fullframe DSLR.
Let see if it's true since the price is very low, but it would be a great stunt.

The sensor though will be most likely Kodak so a KAF-31600 31.6 MP CCD sensor link

Yes it seems we are thinking the same
The focal length is fixed and the projected image stays the same.
The equivalent focal length is only to get the same AOV.
AOV is important because that's relative to the sensor size and how big on object is on final print (or relative to the sensor).

I'm quite against using equivalent focal length since most users have never had a SLR so they have no idea what a 300mm lens does on that, it's better to forget and simply go with your experience.

I can't really agree with that though, how on earth would we have photos of sport 50 years ago while there wasn't any AF to begin with.
And the shutter sound doesn't carry so far to scare the birds away

Pentax probable didn't make a lens longer then 300mm since their would not be so much demand for that. They probable though it was more important to get the 60-250 out and the 200, 300, 17-70, 55, etc. I believe they did the right thing to be honest.
They now have a solid digital lens range so they can now focus on the bit more exotic lenses.

I don't think we can blame the DSLR for that, I believe internet is to blame here more than anything else.
It's so easy to show your photos now to a public you would never had without the internet.

With digital we have besides the full atuomatic mode (which Lemmy speak off?) also the half automatic modes like AV and TV, have those change on the digital camera?
Besides that with digital the lightroom has come to us, almost no one leaves there photos untouched so we need to learn more about that now to get good results.

I don't think digital have diluted the art of photography but it has changed it though, make it more accessible for some but also harder for some others.

Quite true but you base your focal length on what they do on 35mm since you're used to that.
What if someone is shooting whit a 6x7 camera, for him a focal length of 90mm is standard and 300mm is nothing special.


a 400mm f/5.6 would be welcome addition to pentax, Don't think we need or will see a exotic 600mm f/4 and such lenses.

@John, the 600mm f/4 is now discontinued, at least it listed there on the Japanese site.
The price is 1,417,500 yen (£9535)
