Sounds like another recent dodgy dossier I can think of!

Rodger,

The Ports lens probably doesn't pass all the relevant exif info to the body, hence F0.

But not very well!

EDIT:

Here's a thought - Ben mentions better exposures - has anyone who has had problems with manual lenses, upgraded to 1.11 and re-tried their tests?

It's raised an issue I have noticed when using SilkyPix. My PC slows right down and the hard drive goes mad, even when editing normal jpegs. I don't mean resizing just general editing. My PC has 1024mb RAM buts still slows down when using this program. Any ideas ??
Pete,

How big is your swapfile? If it is very small, increase it, if it is very large decrease it! I know this sounds counter intuitive, but if Windows sees a massive swap file it thinks "Great! huge swap file!" and keeps swapping out to disk instead of using the physical memory in the PC.

As a Microsoft Certified Systems Engineer since 1999, I have absolutely no intention of ever running Vista on my own machines. XP will be the last mikeysoft OS I use, it'll be all 'nix from here.

The following information appears on the katzeye website regarding it's effect on metering. Have you found any problems with this screen?

Because of the presence of the prisms, the Katz Eye™ focusing screen for the Pentax K10D will have some effect on the camera’s light metering. Test results for each of the three metering modes are as follows:

* Center Weighted Average (CWA) Metering Mode: Our testing showed CWA metering mode to be accurate for all AF lenses having a maximum aperture of f5.6 or larger (lower f number).
* Evaluative Metering Mode: Our testing showed evaluative metering mode to be accurate for all AF lenses having a maximum aperture of f5.6 or larger (lower f number).
* Spot Metering Mode: Our testing showed spot metering mode to be within factory tolerance for all AF lenses having a maximum aperture of f2.0 or larger (lower f number). Lenses having a maximum aperture smaller than f2.0 (lager f number) will show a significant shift toward increased exposure, with the shift increasing for lenses with smaller maximum apertures. Spot metering mode is NOT RECOMMENDED when using a split prism focusing screen with lenses slower than f2.0. However, if spot mode must be used, it is strongly advised to first take a test shot, check the histogram, and adjust exposure compensation as required.

I think, reading between the lines, that someone in the Riley household may be employed at Jessops?

John,

Agreed, there one bloke at my local "J" who's really hot on all aspects of photography. He suggested I buy a pentax when I got my first SLR back in '96.

What I actually meant to imply was that the average first-time purchaser of a DSLR was unlikely to ask too many probing questions and may be won over by the more-pixels-are-better argument. I know that a few years ago, I would have been!

How very, depressingly, true.

The problem with cramming a lot of pixels onto a chip is noise. As I understand it you start to get leakage from adjoining pixels, from (I think) quantum effects. Oh and reading all that information off the chip in a timely manner. OK, the 2 problems are.....

There was a discussion at DP review about these problems a while back http://forums.dpreview.com/forums/read.asp?forum=1036&message=14849741
