Mate, as has been mentioned already, 300mm is 300mm, don't worry about the 460mm field of view. When I first got my K-1 and put the DA*300/4 on, the camera defaulted to crop mode. To fix that I changed the crop setting to 'FF'. The only change you could see through the viewfinder is the crop square disappeared. Everything else stayed the same except now the full sensor was being used when the DA*300 was mounted.
I wouldn't be worrying about it too much as the DA*300 is a great lens to put on the K-1. I have used it with the K-1 at a motocross event, then before I went back for the next one I picked up the 150-450 so I have these two lenses to compare and the resolution achievable from both is really good. You can check both of them out here:

So my recommendation is to set your K-1 to FF mode (camera settings, page 2 option 3) and start enjoying a smart decision to pick up the DA*300. I still have mine.
