Maybe they noticed the A15/3.5's going for $1000+ on eBay and decided to revive the old design with a few modern tweaks.

The Canon 18-55 looks like it has much better MTF performance which should directly translate to sharpness...

The DA 18-55 is being replaced by the 18-55 mkII, which has a new optical formula for higher performance to suit the 14.6 MP sensor, due in 6 - 8 weeks time, will be the standard basic kit lens for bothe the K200D & K20D.
Expect a significant improvement!

Gawd, I hope not! It would probably have to be very slow to be a pancake 15mm, even in APS-C format. I'd be very upset (and surprised) if it were any slower than the old 15mm f/3.5.

I'm hoping that given how Pentax's new cameras have some form of weather sealing, ALL new lenses down the road will be weather-sealed. Maybe they can differentiate the DA*s with more substantial sealing to keep that line's quality higher, but Pentax could really carve a useful niche for itself by offering an all-sealed DSLR system...

Great info, very useful, many thanks!
So the 1.7 was an AF adaptor not a converter, was it for -L or -S lenses or both?
I really hope they produce both a 1.4x and a 2x and why not a 1.7x.

Not so weird. Their previous generation of teleconverters wereThat's a pretty weird name for it. And no indication of
magnification factor?
called "Rear Converter-A" lenses. Note: "lenses", not
"teleconverters". They produced four of them:
1.4X-S Rear Converter-A
2X-S Rear Converter-A
1.4X-L Rear Converter-A
2X-L Rear Converter-A
The -S were for lenses 300mm and less, -L for lenses longer than
300mm. They are outstanding "lenses". No image degradation at all.
(I have three of them.) My hunch is a 1.4x for sure, and maybe a 2x.
But, 1.4x for sure. It is a well known optical formula.

The 1.7x was a different "animal" completely. It is of the "F" series, (I think). The teleconverters were of the "A" series. The 1.7, in addition to the focal length multiplication factor, "converted" your manual focus only lens into an auto focus lens. That is the greatest draw of that "lens". I don't have one (too expensive), but from reading here on this forum, it works with lenses of all focal lengths.
Since all lenses since the F series are already autofocus lenses, there is no need for a manual to auto focus "converter" for the F, FA, FA J, and DA lenses.

This is correct. I had mine in Jan or early Feb of 2004. It was released in Dec 2003.

Hmm, are you assuming it's going to be a cropped-sensor only lens? Or do we know for SURE that it will or won't? I'd definitely agree that you'd probably never be able to make a full-frame lens of that apeture, but hey Canon makes 24mm full-frame f/1.4 lens, and Sigma has 20, 24 and 28mm f/1.8 full-frame lenses, so a 15mm digital-only lens at f/1.8 (or just f/2?) should be dooable...

Hmm, yes, but there are other aspects of IQ than sharpness, and besides, is it much better? The Pentax seems to be quite a bit better at 55mm, where the Canon is really bad in the corners.
