Tim are you going to post your Michigan Avenue Bridge aerial shots any time soon?

Do you happen to know that there is any advantages shooting PEF rather than DNG? Lloyd Chambers got his 645D yesterday and is wondering about the question. You may tell him directly of course.

The light's not right yet.

I read somewhere that the question of PEF v DNG was posed to a Pentax tech who answered that there was no benefit, but it would be good to have a more complete understanding of that. More tests.

Hi Tim,

It would be really interesting to hear what kind of results you are getting focussing on subjects 50' to 500' away, with a variety of lenses. Are you finding it's tack sharp?

(Don't bother stopping down below f11, btw - the difraction losses become really noticable).
