I am the person who took the casual shots. They were meant as such. One person wanted to see the difference in range between the Pentax-DA 16-45mm and the Sigma 17-70mm. I shot them all in RAW and processed them quickly as I normally do: remove distortions, etc.

The DA16-45mm suffers a bit more from purple fringing than the Sigma 17-70mm. This is especially clear at 16-20mm. You can correct that by using Photoshop, just desatureate the magentas (or blues).

In real life shots you won't see much purple fringing. The Sigma 17-70mm is practically free from purple fringing.

My first copy of the DA16-45mm was soft on the left side. Therefore I posted some pictures:

Those pictures were also processed, but my first copy of the DA-16-45mm was unsharp, especially on the left side. My second copy is perfect.

My first camera was a Pentax ME which I traded in for a Pentax ME Super. Some time later I bought a Pentax K1000. The last film SLR I bought was a MZ5 N.

For me Pentax is lightweight and innovative. But in 2004 I bought a DSLR. The Pentax istD was twice as expensive as the Canon 300D. So I bought the Canon 300D which is a good camera.

Last Wednesday I bought the Pentax K100D because of the SR. When I held it in my hands I had missed the Pentax feeling for some 2 1/2 years. And when I was home to get to know the camera better, I immediately realised what else I had missed in those 2 1/2 years: the personal Pentax feeling. With the Pentax I can personalise all the settings as I wish it. That is impossible with the Canon 300D. With that camera you can only adapt the setting as Canon wishes it.

It feels good to be back in the Pentax world.

You may be right, but when your computer does not cooperate, it doesn't work.

Six months ago I bought a Sandisk Ultra II 2 GB card and it worked like a charm. Two weeks ago I bought another Sandisk Untra II 2 GB card and the cardreader in my computer did not accept that card. When I looked in the system's log files I saw all kind of errors. A second Sandisk Ultra II card did not work on my computer either. In the shop they were no problem on their computers.

The Apacer 150x 2GB was no problem.
