Still like the size, weight and fit with the battery grip.
Perhaps the K-7/5 is more comfortable without.

Phase AF and Contrast AF will lock on to different things sometimes.
The Phase AF may prefer the sharp edge where as the contrast AF will prefer white/black.

But still many lenses wider elements then needed, just tested it with the DA*50-135 it's amazing how much you can block from the front element before it will show up.
I have mounted a 45mm aperture on the front of the lens starts to show visibly noticeable vignette on the 50-135, I've tested it. That is only 3.5mm less than F2.8 at 135mm. So no, it doesn't take it well, vignette is almost immediate.Tyr wrote:

Do you've a read about that maybe, that's just something i don't understand although i know you're right.If it is in front or behind it will only vignette because of how the light rays are focused.

as for the displays, there will be nicer displays when the prices drop, but in the mean time I think Apple went with (what still are very good screens) the notion that most people are using external monitors with thier laptops for the majority of thier work and using the built in screen when they have to.
I know my laptops get used as desktops 95% of the time, so it has never bothered me....
Good to know. Rarely use Macs so I don't learn these things.Tyr wrote:
Also, if they can get nice small high quality IPS panels for their iToys why can't they put that into the Macbook Air or Macbook Pro range? Then I'd get one for my photography work.
What I'd love:
11in Macbook Air with IPS panel and sRGB colour gamut. Only down side would be resolution but at home I could always plug in to my 22" IPS panel.
there is a litlle tab in the bottom right of the window that you can use to manually resize the window upto full screen, and when used with the trick (f3 & click on the windo you want) seems like a pretty easy way to get what you're asking for.Pentaxophile wrote:

I just can't go back to a TN display after having an IPS which I can look at from any direction without worrying about accuracy.

Does the flash have a fully manual mode with power level control and does it zoom?

Thanks Tyr but still worth a try to see if you can mimic it with a gradient filter.
It has a centre graduated filter in the middle of the lens next to the iris. Clear in the middle, darker to the edges. It is not a coated or dyed filter, but is actually shaped (negative) lens element. By making the lens element out of grey tinted glass, the thicker edges of the minus lens are denser than the thin middle bit. Simple idea, quite brilliant. It means that wide apertures have a graded edge to the iris shape, instead of a clean circle, but small apertures are not affected and there is less speed loss. It looks a bit like a 'centre filter' as sold for Super Angulon wide angle lenses.
This looks promising.

The problem is you'd need to put the circular graduated filter in the lens assembly.
If it is in front or behind it will only vignette because of how the light rays are focused.
As the glass has a varied density as part of the optical path and design the effect is very different.

I have been tempted to build a marble lens from scratch to try out on my K10D. Just need to find a nice clear piece of spherical glass and give it a go.
Nice shot!
Nice shot!

I cleaned the mount on mine a few weeks ago and it came off black! It didn't look dirty until I started cleaning it and realised how bad it was.

Thanks go to my wife for posing.
Didn't know which shot to choose... I think the theme here is dark enough.
