Can a drone work half a mile away on remote control???

Hmm could be a toughy that, the guy i saw his shots where being used for a double spread in a magazine.

Half a mile range is going to need some serious kit, far beyond wifi to transmit and tether a camera to control it, i dont know what the solution would be for that...

Well as far as I know there is nothing in the recent Pentax range that can do what you want out of the box.

The new go pro Hero 3 Black edition has a 12 megapixel sensor which I would have thought would have been sufficient for your needs. I spoke to a guy who was using a drone at Global Gathering this year and he normally shoots Nikon D4 etc and he said the new GoPros where the best for the job. Particularly with the iphone / ipad app which has a range of 600 feet.

K-5 to ipad you need a cheap chinese sd / usb camera kit, this will import jpegs and raw

Unless you use itunes you can use dropbox or skydrive etc for transferring images between ipad and pc and vice versa.

Go pro is made for this kind of thing and a lot cheaper than a k-01

You shoot indoors at f/8???

Even with a flash on younare going to get blur as the shutter speed will be to low even at iso 800

You really need some fast glass to stop the focus hunting, focal systems need light and f/5.6 lenses are going to restrict the focussing speed, accuracy and your hitbrate as you have found out. Also the k20d is ancient in dslr technology, particulalry its focus speed.

Oops grammar police alert...

Doh!!!

So the 120-300 2.8 can be converted to Pentax but nit bought in Pentax, bizzarre. I was rather hoping the 100-300 f4 was going to be on there and snap up a cheap canon mount version.

Maybe the focussing on the new Pentax dslr are that accurate the sigma kens doesn't need calibration....
