Thanks for the clarification eReL.

So the patent is more for the 1.3x crop sensor, then, I guess...
1.3x? Why do you think so?

Just a guess on my part, with all of the DA lenses having the common denominator of an image circle enough to cover a 1.3x sensor, as per past discussions here.

Someone on photo.net put the 16-50mm DA* on a film body and demonstrated that it doesn't actually cover 1.3 (or 1.25).

I haven't been following threads in photo.net. So are the new DA* lenses more of D-FA lenses?

You mean both DA* 200/2.8 and 300/4?

Well most probably they will cover 24x36 frame but don't ask for an aperture ring... I'd say 90% chance they cover 24x36.

That's good. At least it'll increment the lens line-up for full-frame in case the market clamors for it (FF). Let's hope January brings these babies out.

I see the FF(full frame) as a dead issue. that decision was made when the decision was made to downsize the lens size. apparently the option of an intermediate sized sensor midway between the APS-C and the Ff has been preserved, and if a decision is made for a future high end body, it would make a lot more sense to make it to work with the existing lens family than for a non-existent lens family.
Full frame is not a dead issue. Pentax may want people to buy DA lenses now and (hopefully) get rid of their full frame lenses. Then it will introduce a full frame and people will then be buying full frame lenses, "optimized for digital" will be the selling point for those who already own full frame lenses. Lenses are a lot more profitable than cameras. Therefore being APS-C forever makes no sense, since at some point people will stop buying DA lenses because they have enough of them. Releasing a full frame camera will rekindle the demand for new lenses.

Sure, sure in 24x36 era, no one bought lenses in the end because they had enough of'em.

-A shake reduction system for a full frame sensor. Huzzah, apparently they have an idea to get shake reduction even when the image is exposed to every pixel and every line!


Sounds interesting, but I wonder if it will require larger lenses than the old ones made for film.
