Thanks, normhead. Much appreciated. I would take note of what you have mentioned. Yes, I think I might need to wait and find out what the final deal is. Cheers!

All great lenses. If you talk about FA*85mm then that is a good lens to own.

Why do the haters hate?

Are they as Ahab to the Whale?
All visible objects, man, are but as pasteboard masks. But in each event–in the living act, the undoubted deed–there, some unknown but still reasoning thing puts forth the mouldings of its features from behind the unreasoning mask. If man will strike, strike through the mask! How can the prisoner reach outside except by thrusting through the wall? To me, the white whale is that wall, shoved near to me. Sometimes I think there’s naught beyond. But ’tis enough. He tasks me; he heaps me; I see in him outrageous strength, with an inscrutable malice sinewing it. That inscrutable thing is chiefly what I hate; and be the white whale agent, or be the white whale principal, I will wreak that hate upon him. Talk not to me of blasphemy, man; I’d strike the sun if it insulted me.

Couldn't find one that said the FA* 85 F1.4 had a CA problem... Any thoughts?

Well it has CA for sure, but I don't considder this as a big problem. Lenses are what you can do with it and not about the things you can't do with them.

To me the biggest issue right now is, if Pentax were to release a FF frame with shake reduction, would the old FA lenses have an image circle big enough to allow it's use. If you're going to use an FA on a tripod on a 2 second delay it makes no difference. If you're going to shoot concerts or something that needs the extra couple stops SR provides, you might want to wait and find out what the final deal is.

(...).
Do you know how many Minolta lenses happen not to have an image circle big enough to allow their use on Alpha 850/900/99 (24x36 cameras with on-sensor shake reduction)?

The answer is: none.

Yeah, but that's completely the same.

My DA 18-135 has erratic vignetting caused by the SR. It happens on my APS-c camera with a lens designed for it, and you say it can't happen of a lens that wasn't designed for it.... fine, don't consider this, go ahead and stock up on all the FA lenses anticipating the FF. All I can tell you is the patent applied for for the 70-200 had a larger images circle than would be needed for an FA lens. It's no sweat off my back one way or the other.

Another possible reason it has taken so long. I wonder if FW could slightly digitally crop the image and still permit SR?

No, it didn't. The claimed image circle in the patent was sized precisely for FF. No larger.

First time I hear that ! My father never had problems with his 18-135. I never had problem neither with my DA lenses (DA15, DA21, DA35, DA17-70, DA50-135). Many buy sigma/tamron zoom and prime dedicated for APSC, I never heard they were made to support shake reduction (as they are primarily for Nikon/Canon after all) and I never heard somebody having a problem with theses lenses.

Honestly I would not bet anything of the supposed DA lense that cover the FF image circle to work on FF camera otherwise than with an APSC image as they were marketed as APSC only. But I don't see this shake reduction to be a big problem for any FF lenses.

That's because slight vignetting is corrected very easily. It's not really a problem. The DA 18-135 is a super versatile lens.

As for the image circle of existing lenses being a problem on an FF K-mount camera with IBIS: As long as the SR can be turned off there won't be any problem.

I think it will be OK. Maybe there will be a little more vignetting with older lenses, but as Clavius says, you will always have the choice to turn SR off if it bothers you, or to fix it in post or, just to crop the dark corners out. I think most full frame lenses will have an image circle that is at least a little bigger than 24 by 36 sensor -- biggest problem would be with really wide angle lenses and there SR is probably not as important anyway.

For me, it's still a toss up, 645D, 645z, full frame, or stay exclusively with APS-c. So my natural inclination is keep the money in the bank. I have lots of FF lenses already. There are still a few (31 ltd. and DA* 200 2.8) lenses I'd like to add to my APS_c collection. And the lenses I'd want for my FF are not available, as they'd all be in the 14-28 range, where Pentax has nothing for sale in FF glass. They do have a 25 in MF and the 28-45. + Pentax making the 14, 15 and 21 APS-c only lenses, is at this time troubling in terms of having to expand the line up. What are they going to do? Sell 2 15s? maybe a 24 and 28 for FF? They have lots of places to go, but nothing in place. I'm hoping they release some glass with the camera to make it at least an option.
