yes I agree about the borders.

About the rest maybe I worded it a bit wrong.
A 10mp 135format has larger pixels than a 10mp APS-C sensor that means the resolution/resolving power/sharpness of the lens must be 1,5 times higher on APS-C than it must on 135 format if we leave the difference of the pixel quality out of it.
Does that make sense?
So the smaller the sensor and/or the higher the resolution the more details the lens has to deliver to make use of it.

That's what we know now, if you look at his first comments it looks like he didn't want the crop so he wants an 135format and he found APS-C strange, because of that he's buying a 4/3th system... it didn't make any sense.
Now that he will use 4/3th as a compact system it does though.

With the K20D and the K7 you've the options ON or AUTO, don't know how it is with the KX, KM and the Kr.
The K5 seems to have the function to set it OFF like you could do with the K10D and your GX10.

So if you've the option to set it off in the menu this hack has no use for you so don't use it!

Here in the Netherlands you're allowed to use your telephone as a dongle, maybe there are carriers in the UK that allows the same?

Actually it's the other way around.
Because the sensor is smaller a smaller part of the lens is used so any fault there will be larger relative compared to a larger format sensor.

Also smaller sensors have a higher pixel density meaning they can see smaller details.

Flossie have you shot the RAW in PEF or DNG?
The K5 uses a new PEF just like the PEF from the K7 is different so it isn't so strange no program would be able to open those yet.

Thank you Adam, will check it out. I didn't follow him recently and I slam myself for the head I missed his concert here, cerrtainly when I read in all the reports how amazing it was

Can you maybe wait till January February next year?
AMD is bringing out their new Bobcat CPU for netbooks the end of this year and they look very promising.

The AMD Ontario Fusion (Dual core Bobcat CPU + DirectX 11 GPU) for example use 9 Watt tops and can play 1080/24p films without a problem.

The newest dual core Atom the N550 use 8 Watt tops and can't play 1080/24p so you will also need a GPU with that like the Nvidia ION2 but that also use 6/12 Watt depending the version, so the current ATOM solution use 50% more power.

If you need a netbook now though and want to use it outdoors then the Asus Eee PC 1016P might be the best choice at the moment.
It has a good high contrast MATT screen that is usable outdoors and at max load it has a battery life of 4h 42min but when surfing the net with WIFI on it can last 7h 53min

Here is a review link

That doesn't always work.

Simply make a photo an over exposed photo at the widest aperture, everything you see on the photo pure black is dirt on the sensor, or actually dirt on the protection glass/filter of the sensor.

It's grease and things like that that you will see if it's on a lens but dust or an hair you will only see on the sensor if you use a high f-number like f/11 or higher.

This seems to be just dirt on the sensor, it's one of the problems with interchangeable lens systems.
It's quite easy to clean it yourself, the best tool is probably the artic butterfly.
It does cost quite a bit but it works for a long time.

I don't see why Micro four thirds is a good idea and APS not???

Micro four thirds is a good concept because they have a specialised mount but the lenses are far to expensive compared to APS-C. I would rather see that they make a specialised mount for APS-C so that it's easier to make faster lenses for it so it makes the lost of DOF go away compared to 135 format.

Also APS has more right to be around because APS is from 1996 and 4/3th only from 2003.

btw the term FF needs to be used carefully because Full Frame means the sensor is the full size of a standard.
Pentax and Nikon use FF APS-C (roughly) and Canon is using a crop APS-C sensor.

But 50mm remains 50mm, how can the size of a sensor change something as physical as a focal length?
It doesn't matter if you put it on a 4/3th sensor or on a large format.

I can see that you're used to the 135 format and that the APS-C feels alien to you but then I don't understand your decision to go even smaller than that?
If Pentax would have created a new mount so you couldn't use your older lenses, would you have feel the same about the APS-C format?

Yes sadly they aren't the pioneers any more like they used to be.
But still the camera's and lenses from Pentax still feel good, also Nikon does feel like a camera make for photographers I don't get that feeling from Canon camera's they feel more technical so to say.
At least those are my feelings.

Also EVIL camera's just don't feel right in my hands, they feel so disconnected from the photography... all you do is stare at a screen all day when taking photos. At the moment I'll not buy one for sure, maybe over 40 years when I don't have a choice any more.
