I believe 'pros' would use a suitable reflector to bounce natural light into the shadowed face. My concern with the flash photos is that the shadows caused by the flash are in a different direction to the sunlight shadows so subconsciously doesn't look quite right.

Generally I feel that 'shadow recovery' should be reserved for unimportant areas of an image (eg underneath tress and undergrowth). I don't see it as a valid technique for use on the face of a portrait, which I think should be lit and exposed correctly as you want it at capture. Of course, I'm a K7 user, and I have to suffer noise in the shadow areas .... a K1 user would no doubt have far greater success with this technique .... but still, I like to try and balance things correctly at capture if possible.
This is all about using what resources and approaches are to hand and practical in the circumstances of course ..... its about which one of the compromises available works best for us.
I'm presuming you haven't made traditional prints in a darkroom where burning and dodging is normal.JAK wrote:

I was hoping this wouldn't have to be moved to the post processing forum! If you'd used raw the shadow detail could be brought out. This is part of the way there just from your jpeg using the burning and dodging technique. I feel this is more natural looking than the lighting produced by the flash.

The image I experimented there lacks the dynamic range of a raw file so can understand your comment about that example. It did however recover some of the face detail. While the K-1 doesn't have a built in flash it does have a good dynamic range which helps recover those shadow details.

Were they tested with the same sensor, or optically bench tested?What surprised me was that the dxo tests found the Pentax 21mm Limited to be slightly inferior in sharpness, and some other respects, to the Sigma zoom.

This video gives an idea of how Image Sync works on an iPhone, the iPad will be similar.

Also, is the tethering just to transfer images right away or to act as a remote control?
Image Sync is available for both Android and iPad etc. but not PC. Given Image sync is a free download it's worth trying first however I find it doesn't transfer the live view image as intended though the remote control button function works.

From the ePhotozine test: "Overall I'm a little disappointed by the lacklustre performance towards the edges at maximum aperture."

A generalisation, but Sigma lenses often seem poor at the edges though really sharp in the centre.
Our little 18-55 Pentax's are actually pretty good compared to other marque's offerings with edges great compared to a Canon equivalent. A comparison I did some time ago saw a bar code on the edge of the image could be clearly read on the Pentax but the Canon's was just a blur.

If you took your car to a garage and a mechanic said your wheel bearings need replacing, and it would cost X amount to fix, and you said OK I will take my car away to think about it, you wouldn't stand for it if they said sorry we can't let you drive the car away unless you pay us £24 would you?
As to that power supply, why not phone Pentax dealers and ask them if they have one tucked away on a shelf or clearance bin? You never know. There's a K-ac84 for sale on eBay in the States presently but the postage will cost more than the adapter. It might not be the correct mains voltage however. Hold on a week or two and one may pop up on eBay UK, that's how eBay works. Quite possibly someone here has one but they've yet to pick up on your thread.
I expect other adapters could be used if they have the same voltage, power output and connector. Try Maplin.
