The only thing I can think off is that one time it approach the focus from the front and the other time from the back.
Since the field of focus is a certain distance wide the focus can be a little different but not by much though.

Indeed it's an even field qua quality so that's very nice

And this doesn't apply to th DA*55 f/1.4 because?

Was not talking about just the FA43 but all FA and film lenses.
It's just that those lenses are never made to be used on digital and they are missing some optimization. I wonder if there is a service that can coat the rear element to improve them on digital?

I think i got it.
But field curvature is only one aspect of a lens so how can you call that overall performance? Also so far as I know only Macro lenses are designed to have a very flat field and i don't see why it's important with normal lens besides very fast ones or at least why it is more important than correcting other aberrations.

Just a note but I believe having a flat field curvature or little astigmatism is the same thing or are at least closely related.
And meridional plane are you sure about that, don't you mean sagittal?

Don, there are some problems with the uploading part.
It might be a good idea for some photos but with my last vacation shot 12GB worth on photos, I don't think its a great idea to upload them and certainly NOT abroad.
What would the roaming cost be than?

You also need an awful lot of iThings to get it to work, I at least have non and sounds complicated.
Why not a netbook with a 250GB hard disk and with a kind of video out?
It can store the photos and display them on not just yours but any tv and that for the same price an iPod 64GB touch cost.

But what if the camera could be that device.
The camera has a card reader, USB, LCD screen and controls all you need is the ability to recognize USB storage device (I believe that's a standard code) and instructions so you can copy/backup photos.
The camera can already read FAT and all PC OS can read that as well, what more do you need?

But you still need to take with an extra device for than

If you're going to take a storage device than the iPod/iPhone/iPad isn't the way to go because they cost a lot for just storage
It's better to get extra SDHC cards.
For the price of the iPod touch 64GB you can almost get 3 Sandisk Extreme III 32GB cards.
And if we compare it to a Western digital 2.5" 1TB USB hard-disk you can get 2 (and a half).

So if a camera can do the transfer you would have great bang for you bucks in term of storage.

Wrong batteries those are 18650 and those are 15mm longer than the 18500 that are in the Pentax so they won't fit

The best I could find were the TrustFire 18500 1800mAh
The cheapest I could find was here link
£8,63 for 2 (Free P&P)

Have you already seen this upcoming Lightroom plug-in? link

So far it looks really good and can't wait to give it a spin.

Is there no way to switch?

I agree with your second point though but it would be great if you could connect an USB hard-disk to your camera and transfer the photos from the card on to that, it would mean for example that you don't need to carry a laptop on vacation or several cards

John how much longer are they?
If they are around 70mm than they use the 18650 batteries so you can up the capacity quite a lot

I just measured the battery compartment of the K10D and that's 60mm deep so you can't fit 65mm inside that

edit: looked up the size of the K7 battery and it's 55mm so those are 18500 as well
