Sorry to hear you decided to sell these lovely lenses Amin. I would have to agree that they are not the swiftest (they are certainly quite a bit slower than my now long departed Oly SWD 12-60 and 50-200 lenses).

It would be great to be able to select screw drive in the menu just to compare. I suspect that it should be easily done but that Pentax might have other reasons for not making that feature available

Mike I think Pentax are on to winner with the K-x

Welcome to the forum John

George is right, if you have a good quality HD camcorder the K-7 will be overshadowed a little (it's still not bad mind you). But if you have older std. definition camcorder then the K-7 is much much better. Plus as George says think of the possibilities when you build up your lens collection

Now with regard to autofocus, it's really not such a big deal particularly if you are using a longer lens and stopping down a little. However it can be more challenging if you are using a lens with a much shorter depth of field.

Hi Stu, welcome to the forum

DA* 16-50 & DA* 60-250.. no failures here either.

Bad things, yes I had seen that too but to be honest I've never really had an issue with Vista 64 bit. It's been extremely stable, fine compatibility wise and runs very well (Quadcore + 4GB RAM).

When Win 7 gets officially released I might give it a try but for the moment I'm more than happy with Vista

Vista 64 bit

For me it's being able to view untouched PEF files full screen in a fast viewer before editing in CaptureOne.

Unfortunately not for 64bit

But the 64 bit codecs for this new viewer work like a charm. I've just purchased the Pro version and viewing of RAW files directly is great and extremely fast. Very impressed by this viewer package.

Thanks for the link. This was very useful as I run a 64 bit operating system
