That's good, but that "golden" ring looks cheap!...black, black, black!
Please Pentax, make them both red or something other than that green/gold combo. It just doesn't look right to me. Or it is just me?

Well the spec. says 60-250/4, which makes it a 90-375mm equivalent. A bit closer to 100-400mm but I guess it's not really a big difference. It must be the optical specifications that brings us these curious focal lengths. Lets just hope the quality is stunningYes, we know they are 35mm film equivalents, but 50-250 is NOT anhttp://forums.dpreview.com/forums/read.asp?forum=1036&message=20122170
It's to match 35mm equivalent. So they're focal lengths back when
ppl still used film (or use full frame). They're not exact because
of the optical formulas, I assume because they work better.
shequivalent at 75-375 in effective FOV on APS C. It would make more
sense if it were 50-260(265). The DA16-50 is a 24-75 FOV equivalent
on fim, the DA50-135 is a 75-200 FOV equivalent on film, but the
50-250 at 75-375 FOV equivalent on film is a bit of an odd bod.

Yeah, it's a bit over-the-top. For me, the coolest thing would be to make the thicker ring green and the thin one near the mount gold.That's good, but that "golden" ring looks cheap!
I believe they have used the 645-lenses as model for the new DA* series. Just look at the similarities in this shot:That's good, but that "golden" ring looks cheap!...black, black, black!

I have been puzzled by it all along. Pentax first announced this as a "high performance telezoom." But high quality zooms usually have a range of 3x or less. This one is more than 4x.Am I alone to not understand the range of the 60-250 ?
They are DA lenses--smaller image circle. Yes, they can be used. What we don't know (Pentax refuses to tell us) is whether they will autofocus with existing bodies.these lenses can be used in existing DSLR bodies?
