The filling date is November 2007 so don't think it's on the F serie.
If you read further you see that the lens moves the focus and that the camera checks it so if it's on the lens today it's on the SDM lenses.

The Pentax software aplies the same process as the camera does to JPG, so they soften it a bit. Most of the time that's alright, surely for small prints.

Same question, just readed the whole thing.
It only says that Adobe Camera Raw produce sharper photos then the Pentax software but that's something differend.

I do know that you get a better continues shooting rate with DNG because that's less compressed so handeled quicker then PEF bit since the buffer is much larger compared to the K10D you won't even notice it.

DNG is support by both software so don't think it would be a problem.

ps. are the DNG's that come out of the Samsung better compressed compared to the Pentax?

Sorry for the triple post but I went on patent hunt and I might have something. link
I'm no expert but it looks very interesting, I also have no idea how new this is, maybe the current lenses with SDM works this way?

I also have something for the people that do macro photography, Hoya has a very new pantent for a new Macro lens system link
They also have new glass and a new method of molding and machine lenses, so they are quite active.

Or shake it, just like you do with some watches

I don't know they said this
"PENTAX plans to revise standard DA lenses that will to be fit to new K20D class model."
and this
"We are interesting in the system change by the mirror-less method, however our priority is to complete our lens-system."

it seems to me that the lenses stays the same but that maybe a feature is added. what that is I don't know, maybe we see powerzoom back again or they go to full SDM with the lenses to come although that wouldn't be so new... maybe they develop something, time to check if they asked for a patent

interesting shots and very creative Karl.
The last one is my favourite but the second one also has something.
With the third shots i'm not so happy with the framing on the right top, just a bit too heavy but still a nice shot, if you had the people in there infocus it wouldn't be as balance as it is now.

Wonderfull shots Nathan and the lighting looks to be okay with my ameteur eyes, no hard shadows and natueral.

1. I don't believe there is much of a difference but in camera the more standard tools are more at hand. also I don't believe that you can change the white balance and such in photoshop (elements).
I try to get the most nateural photo with camera raw and do the sharpening and more creative things in photoshop.

2. there is a diffrence, watch the historigram in the top right and you see it. Simply get the one what you think is the best, sometimes the other is better for portrait and others for landscape. I've it most of the time set on Adobe standard.
