I think this is a good thing. Incremental upgrades are still upgrades. Will I buy the new lenses? Maybe the 15, but it was on my personal lens to-buy list anyways. Will it make me get rid of my FA limited lenses? Definitely not.

Oh yes, the A 50/1.2 was just recently finally retired from the Japanese market, and both the K and A versions are pretty expensive used, so there definitely would be a market for a new version.
I smell replacement on the way then. It makes sense to me. Upgrade the current lenses to handle higher resolution sensors, then release new ones along with new cameras. If the LX-D is in fact true, it might be using the 36 MP FF sensor as that sensor has shown that it could out resolve the current generation of Nikon lenses and coating. And what did Pentax just do? Update lenses with "HD" coating.

P.s. I think the FA limiteds will be getting the HD and WR treatment. Why not the DA's? Well size is a big factor. Adding weather seals to tight tolerance lenses is not an issue, but it would require more space, thus breaking with the DA limited design philosophy. The FA limiteds are lenses that are designed to be the pinnacle of resolution and light handling/gathering with emphasis on IQ. Size is not a constraint with FA's so I think we can expect them to have WR sealing. Just my .02.

Which, of course, would set you back probably $1,500 (check out the prices for the Canon EF 50/1.2 USM. The market for this type of lens is certainly very small.

And anyone that has ever held a Pentax 50mm f/1.2 will realize that such a lens will not be keeping with the "small and light" tradition of Pentax Limiteds. There is a LOT of glass in there.

Why do people voicing such strong opinions know so little? The DA15 and DA21 have always had 7 aperture blades, and the new versions still do, as they should. The 14 point starbursts they produce are fabulous and stand them apart from the overly-busy 9 blade ho-humness of just about every other premium lens.

All the other haters can go jump. This is great news; Ricoh/Pentax are committed to continuing the DA limited legacy and these announcements (along with the *awesome* news about two new WR flashes) is no doubt the tip of the iceberg.

I don't know about that. The old Pentax 50 1.2 has always been lots cheaper then the Canon versions. Even though the Pentax variant is MUCH better. And if I look at the price of of the Pentax 1.2 in the used market, and how fast they are always sold, then I think the market is quite large. 1.2 has always some sort of holey grail for a lot of shooters.

Moreover, focussing the old 1.2 manually with a stock focus screen is next to impossible. That creates a certain barrier for a lot of users. But if the autofocus of a revamped HD DFA 50/1.2 is reliable, that barrier is gone. And the market would be even bigger.

It's my understanding that the coatings are more about decreasing reflectivity/flare and increasing contrast rather than improving resolution, which is a function of the optical design. That plus the fact that the lenses refreshed so far are DA (i.e. crop sensor format) make me question whether the new coating is a sign of FF cameras to come.

Yes, I am. From the Ricoh website

I guess they are not the ultimate oracle of all wisdom then.

Something may be unnoticed till now: "SP (Super Protect) coating (already featured in four other models) has been applied to the HD PENTAX-DA 40mm F2.8 Limited lens to keep the front surface free of dust and stains".

But doesn't the improvements to flare, reflectivity and increased contrast lead to improvements in resolution as well as optical design? Weren't the Mark I DA limiteds fine with the 16 MP Exmor processor? Why change the coating if the sensors are't going to benefit from it?

DA15 and DA21 still use 7 blades, and DA40, DA70 and DA35 still use 9 blades. It's only the shape of the blades that has been changed.

And the specs tell that the aperture will stay round until f/5.6, except for DA21 where it's f/4.
Thanks for correcting me.. I've been very busy and not reading thoroughly...

About the designation... Since years the term "HD" has stood for 720p, and "Full HD" has stood for 1024p. I have no idea what its doing in a lens coating designation. A bit like saying the tires of my car have 120 horsepower. The horsepowers is not an attribute of my tires.

Even a term like Ultra Multi Coated, would have sounded less cheesy.

Maybe Pentax thinks like me in respect to WR: What use is weather sealing on a prime lens anyway? There you are, in the pouring rain or in a dusty environment, needing to switch lenses from the 15mm to 55mm. You don't want to expose the insides of your precious camera to the lements, nor do you want to be stuck at one focal length. Therefore WR only makes sense on superzoom lenses, imho. The extra IQ of the prime is compromised by the moist or dust in the atmosphere anyway.
I would love it if the DA 15 was sealed. If I could stick that on one K5 and my DA 55 on the other, I wouldn't every change lenses...
