Sorry might not have been fully clear it's spherical aberration that can cause it

Here is a lens.


Wide open the best point of focus is at point B since the beam is the smallest there so the sharpest but the AF can very easily see point A or C as the sharpest point since the lines cross there so you get a focus error.
Also the amount of chromatic aberration isn't helping either... it's like asking to find the sharpest point of light in a rainbow...

Also like said Phase focus isn't perfect, if the mirror, AF sensor or image sensor is slightly off the image will not be in focused.
Contrast AF is the most accurate focus since it looks at the focus on the image itself so you eliminate basically all the elements in between.

Shortcuts are almost the same besides alt, ctrl, since mac doesn't have ctrl or alt but Mac key or something like that, but they did switch the placement/function of the keys around

But it's the way the windows are managed that's breaking it up for me, searching for the right window with your photo while you're busy making a collage with 12 photo's was just a pain. Hopefully things will improve with your tips.

Same here I just picked the right versions
windows 98 was quite good and upgraded to XP 64bit, that one used a different Kernel than the normal version and was much more stable, skipped vista completely and now running Win7 for several years now without a hitch.

I've heard of plans of making Win8 cloud based, i don't like that idea

Thanks Gwyn

You can use sun flower oil but you need to warm the oil up with an heater to make it easier to run and i believe you need different filter if you want to do it right.

But when you think about it diesel is still cheaper, there is only 8% tax on food products right and more than half of the petrol/diesel price is Tax.....

Misschien moeten we het kwartje van Cock terug vragen

Maybe there is hope they can fix it with a firmware upgrade although they would have probably done that by now...

As long as it run the program's i want i don't care what OS it is but at the moment i'm bothered that both OS run a program differently *sighs*

It's just a pain that things work slightly differently then you used to, it just messes with productivity.

The MBP have IPS panel so far as i know and they so good as cover the sRGB, for the rest you've the RGB led solution from DEll, that one almost cover aRGB and HP have radiant screen or something like that, that one almost cover sRGB but has a very high contrast.

Here is the MBP

Do you've a read about that maybe, that's just something i don't understand although i know you're right.
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.

Fast lenses always give an focus error, read the part about focus shift.

Not only fast lenses though but the effect is most pronounce with those.
When you look at the amount of aberration you have with that lens it's no wonder the AF is off.

In the netherlands you can't upgrade those licenses if LR4 or CS6 is here you need to buy a whole new licenses...

I might look for a plane ticket to be honest ^^

Where is th meet?
