Yes I've heard of those but not seen any suggestions as to when they will appear or how good they'll be. At 1000 times more sensitive we'd presumably need a bag full of ND filters!

I really can't believe that Ricoh won't release a Pentax with one (or both) of the newish Sony sensors 24/36mp used in their Alpha 7 series. Expect we've got to wait until Sony have fulfilled their own quota first. People seem to be getting good results with those bodies with Pentax glass but how better it would be if they were with Pentax bodies. I'm sure Sony wouldn't have bothered if there was no demand for these, so have to hope Pentax feel the same ASAP at which time the high ISO woes ought to be overcome (until we get to 54mp!)

Have a look at used sales on ebay - seems anything between £35 to £110.

No doubt. But let's get a full frame camera first or talk of that is irrelevant to us, we'll be left way behind. Or will Pentax try and squeeze 54 megapixels out of an APS-C sensor?

Also a thread here:

Sounds like a focussing issue with that particular lens, so I doubt it. A K-3 may even make the problem seem worse if you pixel peep.

Camera custom filter settings don't affect raw files, other than perhaps in PDCU if you request it to.

Do you really need a USB cable? I take the SD card out and put it into a slot on the computer. The supplied USB cables never seem to get unwrapped!

The feathering/vignetting amount is set in the cropping tool in Elements. I expect CS5 is the same.

Are the images from a raw file?

Write protect the card so nothing gets overwritten and try Zero Assumption Recovery
