A new series of lenses qualifies as game-changing but actually couldn't even be ON the current lens roadmap, now could it? B
Yes that is logical.
I can't help thinking that there is still some fast focusing WR/AW lenses still missing from the line up. The DA* zooms need a freshen up with something like the DC motor used in the 18 - 135 WR.
Ricoh stands to make some premium coin releasing, maybe under another designation,freshened DA* lenses.
The WR/AW factor coupled with reliable lenses with good IQ is just good to pass up IMHO.

DC motor is more reliable than SDM
Well... In my 2 cent, that depends on how many SDM in their warehouse, they won't replace it until they use it enough

With the limiteds revamped, it will have to be a new aps-c announced on the 5th. Makes sense, get the waves of buzz from this announcement to lead into your new flagship, it makes a very attractive package. I think around march we may see some fa hd's pop up for the april 1 FF announcement.

I guess it's a good thing I never won a bunch of lowball bids on the special edition silver DAs

Contemplating replacing the 12-24 with a 15. The zoom is big (for someone used to Pentax primes) so I rarely carry it. But I'd need to try one first...the "Controls My Mind" thread is about 50/50 for/against.

Do you have any hard data on this please? Exactly how unreliable is SDM? I've not encountered this problem in my Pentax lenses as yet: the only lens motor that has failed on me was in a (very) expensive Nikon zoom. I'm thinking of buying another DA* zoom soon (the 16-50 or the 50-135), so I'd appreciate some facts about this "problem".

There was a forum survery done and the results were very clear; DC is way more reliable than SDM. I've heard of just one DC failure and that was on a lens carried on a motorbike half way round the world.

The only thing we know is that the single DC lens has a lot less motor problems.
It may be the motor itself or it may be the implementation, simply they didn't screw their design and did it correctly this time.

Also, big failure rates are DA* lenses with dual focus, others already have less faults (which doesn't mean they are acceptable).
Things are a lot more complex than a simple forum survey.

FA 43mm Ltd isn't massively far off that

Or a used M-50/1.7, which is quite close to the FA43 in looks and size

True, but the M-50's performance although fine isn't going to be as good as a DA, or have quick shift (not that the 43mm has that either!)

TBH I think that the Ltds cover all the major prime focal length bases now. A fisheye Ltd might be interesting - and the HD coating would be good on that - or maybe adding a longer macro. However I think the line up is mature now.

The Ltd zoom seems a little pointless to me. The focal length looks like it could be quite restricted like this lens: M 24-35/3.5

Let's wait and see - many thought the DA35 Ltd was pointless before people started using it

A fisheye ltd or a wider than 15mm WA would be cool. I wonder if it would be possible at all to make a compact lens in the 10-12mm range?
But if they could make a very sharp fish eye with minimal CA, it could even double as a rectalinear WA (by defishing)

I have no experience with the DC motor. On the other hand, of the SDM lenses I have bought, I had a 2nd hand DA*16-50, and a new one bought last November, both fail on me. One has been repaired under warrantee (and still works), and the other has been converted to screw-drive. My first DA*55 had a broken SDM right out of the box, but the replacement has been fine for over a year. My DA*50-135, DA*300 and (now sold) DA*60-250 have had no problems. That is a nearly 50% failure rate....

They are all wonderful lenses in every other respect.

I think they should have kept the green ring rather than copy the red ring from Canon.

I think Pentax lenses in general could use a bit of an update, so in principle this is a good thing. However, they should have taken the opportunity to redesign the 21mm to make it a tad faster (f/2.8), reduce the barrel distortion and maybe increase sharpness wide open.

The apparent price increase is disheartening as the current limited lenses are already over-priced for the optics they offer.

What the limited line really needs is expansion - a new 35mm f/1.4 like that offered by Fuji has been missing for a very long time. Fuji are fast over-taking Pentax as having the best APS-C lens line-up available. Yes, it will be larger than current DA ltd lenses but I'm confident that it could be made no bigger than an M series 50/1.4. A longer ltd lens would also be nice, a 100mm f/2.4 for example. On paper this would be close to the 100mm macro, but would be much smaller without the macro capabilities.

Wasn't aware that using colors constitutes "copy".
