DC motor, and WR! Kewl :-O

"From readers, we have to provide information about the new interchangeable lens of two Ricoh (Pentax).
  • possibility that Ricoh imaging in the near future, to announce the replacement lens of two of the following high.
  • PENTAX 08 Wide Zoom Lens
  • HD PENTAX-DA 20-40mm F2.8-4 ED Limited DC WR
Was published in the lens road map of Mount Q "08 Wide Zoom Lens" is like a "WIDE" lens. This lens Once released, I will be able to walk through cover to the telephoto from ultra wide-angle PENTAX Q.

"F2.8-4 ED Limited DC WR HD PENTAX-DA 20-40mm" is like a DA Zoom Limited which appeared in the lens road map of K mount as viewed from the focal length. Details are unknown, and the DC motor is built from the name, that you are in drip-proof structure seems to be a mistake. The focus area that is not seen much, this lens, it is going to be a lens quite unique."

Wrong forum, I know - but I'd been hoping the 08 lens would be a small prime, and about 28mm equiv f/length.

if it has to be a zoom I hope it's physically small and decently wide on a mk1 Q...

Well one of those two is very interesting but it isn't the DA. Weird focal range and not even constant aperture.

On the contrary, if you are a scenic photographer you want a lens that performs at f5.6 – 8 and 20-40mm is very useful range. 12-24 is too wide for me. If this comes true I’d be a happy bunny.
 
I've been waiting for that Zoom lens, will see if it will be true (DC, WR and Ltd)
 
Small size. Maybe a little better image quality.

I was really wishing it would be a constant f2.8 or maybe even faster.

What will this DA Limited zoom lens offer over the DA* 16-50mm f2.8?

My guess is the DA limited will have metal barrel, smaller size, and a focus motor that lasts more than 2 years.

The DC motor in the 18-135mm has been extremely reliable according to survey at Pentax Forums, https://www.google.com/search?q=pentax+forums+sdm+survey having not a single failure for approximately 100 reported lenses.

Where the 16-50mm has had very high failure rates. Granted this is not a scientific survey, but still very telling in my opinion.

The SDM motors seem okay in the prime lenses, but not in the 16-50 and 50-135mm lenses.

I imagine as long as image quality is as good or better than the 21 or 40mm limiteds they will sell them, and price is not too high.

We'll have to wait and see. I would like to have seen a more bokeh-licious lens like a 20-35mm f2.0 or a 1.5x FL at f1.8. Seems a bit of a waste for a high end zoom at small FL's having such small aperture.

You have to understand it from my perspective. I’m not interested in bokeh and 90% of my shots are f5.6 and over. There is a complete glut of fast lenses out there (others makes inc). They bring out an f2 and people complain it’s not fast enough. This mania for fast glass is getting out of hand. The problem is that if a manufacturer makes a fast lens the design is biased towards its wide open aperture, because they know that is where it will be judged. Many of these lenses perform less than stellar at the edges; the new sigma 18-35mm that everyone raves about does not look that good to me. Sigma has had a 24mm 1.8 for some time but the edges on that are quite poor. I know I’m more hung up about this than many but there is room in the world for more choice. It is time us scenic photographers get a useful lens.

I don't believe this lens is specifically aimed at landscape (if that is what you mean by scenic) photographers ... if the specs are true, and I suspect they are close. This is an effective 30-60mm zoom lens probably aimed at event, street, group portrait, wedding, premium walk-around type shooting ... landscapers will want something wider and won't want to pay a premium for the focus motor or unusual zoom focal length range. Regardless, if this lens is going to offer something the DA*16-50 doesn't, it needs to be all metal, relatively small, and have premium IQ out to the edge of the frame. Easier sell to DA Limited owners who don't own anything between the 21 and 35/40, but if you've got the FA24, 31, or even the 21/35 combo it doesn't exactly seem to be a must have.

I say scenic because I don’t take the big landscapes you may be thinking of. I use 24mm and 28mm primes most of the time. I don’t like lenses wider than that because they don’t suit my style and the edges start to suffer. If I need to, I stitch two or more photos together. Anyway my take and your take are the big problem with forums, people with different ideas and needs not understanding each other. My point is, not everyone thinks fast and bokeh are so important and at the moment Pentax don’t have a lens which is in the area I want, so this looks good. Of course if the edges are poor I’ll be complaining and others will be saying they don’t see the problem.

Maybe it's a FF replacement for the 20-35 f/4 ;-)

I'm sure it will be a fine optic, but not on my radar.

If image quality is as good or better than the 21 or 40mm limiteds and the size does not exceed the 31 mm limited I will sell my 21mm and 40mm limiteds to buy this limited WR (!) DC (!) zoom.

Agreed -- that 20-40 profile would be a general service lens for most people. If it's in the spirit of the other ltd's, it would be all metal (WR could change that) and have a funky hood. I was hoping it would start at 16mm, but i guess not.
