As a potential future K-1 owner and the current owner of a number of DA lenses, the question begins itself.
I know everyone is super-eager to finally mount those old film-era lenses on the new beast and see how they perform in the modern era, but the Gods gave us crop mode for a reason and that reason is non-full-frame-compatible DA lenses.
Who's tried them out? Just how intrusive is that viewfinder vignetting? Most importantly, does having a little extra space around the crop frame in the viewfinder make a difference when trying to compose, especially on a moving subject? (Logic before the camera came out said yes, it should, but I'm interested to know. Perhaps those with an abundance of bird life, active children, scampering dogs or squirrels and a K-1 could let me know?)
On a slightly related note, I did some DA lens shooting on a Super Program a short while back and the pictures came back just yesterday. I shot three shots - wide open, f/8 and fully closed down - with each of the DA Limited prime lenses except the 35 (it was at work) and with the DA50, and though I found afterwards I had taken two of the DA70 shots unfocused, I was interested to find that I could not see any obvious vignetting with the DA70. More work is required there, but it looks promising. (Interestingly the DA21 shots, with the square hood on to maximise the vignette effect, were asymmetrical - a thing I cannot explain.)
