Maybe to make it different to DA*55mm/f1.4 that has a big pricetag? Or is that me thinking in marketing strategees?
The current price of the FA 50/1.4 is half that of the DA* 55. It is also half the size.

The thing I wonder about this quest is in what way the DA*60-250mm isn't doing the trick for you?

I have the DA*60-250 and also the DA*50-135, DA*50 and DA*300. The DA*60-250 stays home most of the time. It just isn't long enough and it overlaps with the DA*50-135 way too much. A DA*135-400/f4.0 or a DA*135-300/f3.2 with a matching 1.4xTC would pair up much better than the DA*60-250 to the DA*16-50 and DA*50-135. Then a DA*8-16/f4.0 at the wide end.

Well for that maybe the 135-270/f2.8 would be a good match, just not to 300mm.

And with your choise you would say stop production off the DA*60-250mm/f4?

my picks

I just took the survey but found some of the choices odd and was disappointed not to see some other options. Here's what I'd like to see :
  • WR 17-70mm f/4 or f/2.84, or 16-80 or 85mm f/3.54.5
  • refreshed 55-200mm WR kit lens with improved optics
  • 23 or 24mm f/2
  • moderately priced 30mm or 35mm f/1.4 or f/1.8
  • 90mm f/1.8 or f/2 (85mm ok too)
  • 135mm f/2.8 or faster
  • inexpensive 50 or 55mm f/1.7 or f/1.8

  • 135mm f/2.8 or faster
  • inexpensive 50 or 55mm f/1.7 or f/1.8
That is a nice list. At least I got one lens good on the poll with the 24mm/f2

Well I have thought of a 135mm and it doesn't make sence to produce a 135mm/f2.8 since that will still be expensive to produce and eats up on sales for DA*50-135mm. A 135mm/f2.0 will make a difference, but is also an expensive lens.

Kitlenses are for me things that change over time and not in my viewing angle. They are always welcome to improvement every 3-5 years I think.

From the openingpost:
QuoteOriginally posted by RonHendriks1966 Quote
As always, things change overtime. Here I will add new ideas that will pop-up in time:
  • Tilt/shift lens for architecture, like DA 18mm/f3.5 WR T/S.
  • DA 10mm/f4 WR, or a DA 10-16mm/f4 WR or DA*11-16mm/f2.8.
  • Updating FA Ltd series with quick shift and WR or turning them into FA* Ltd.
  • DA 45-125mm/f4 to compliment the DA 16-45mm/f4.
  • DM lensline. Making a new lensline off manual focus lenses with chip, so all communication with camerabody.
  • Convert the TC 1,4x into an extensiontube with full contacts, it is the same product without glass.
  • Expanding the DA* prime's lensline from 20 to 35mm f1.4 with some lenses or a cheap 30 to 35mm f1.9.
  • A fast telelens like DA*400mm/f2.8 or DA*400mm/f4 to fit that bill.
  • Cheaper short tele like DA85mm/f2 WR or DA120mm/f2.8 WR.
  • Cheap DA-L series macro-lens with only 1:2 reach like DA-L 70mm/f4 1:2 macro.
Some of your wishes are shared by more Pentax users!

In the list is a 70-200mm/f4 WR so it would make sence to convert the current 17-70mm/f4 to a WR lens since they where ment to be matcht pairs. Only thing is that this lens misses some popularity in the poll. The 17-70 should get a new version with improveved SDM so making more adjustments makes sence.

Tilt/shift all the way

I wanted to tick the option for the
Tilt/shift lens for architecture, like DA 18mm/f3.5 WR T/S.

But it would need to be a * lens.

Otherwise a FA 24mm/f3.5 ltd T/S.
But this would not be so useful unless a Full Frame camera came out.

The other thing that I believe Pentax should work on is a 645 T/S lens in the 24mm(35mm equiv) focal length. I think this is 35-40mm in 645 language.

Couple it with a new 1.4 converter and BOOM. the 645 could become the go to camera for Architectural and landscape photographers. Canon currently have this market cornered (for those that don't wish to use an Arca with MF back), but the 645 - this could really shake things up.

Although this goes beyond what is in demand for 35mm or APS-C DSLR camera lens requirements...

I agree with this idea, a tilt/shift lens for the 645D makes a lot of sense. The 645 25mm f/4 caters to wide angle photography but that's isn't all landscape photography is about. Tilt shift lenses give you the ability to use a wide aperture and extend DOF beyond what would normally be available and this gives the benefit of being able to stay under the diffraction limit - which is an issue with such a high resolution sensor. And a T/S lens would give photographers the ability to use near/far compositions without the nuisance of focus stacking.

A D-FA 35mm f/4 AL WR Tilt/Shift lens would be a good place to start for pentax

I have the DA12-24 and the 50-135 as my better quality lenses.

I'd like to sell my two kit lenses and replace with a 24-70 2.8, preferably a DA* version.

That would round out my kit quite nicely.

Tilt/shift

QuoteOriginally posted by RonHendriks1966 Quote
Good to bring it up, since I only thought of the tilt/shift lens after I put up the poll. Put it in the first message. You say 18mm, but I also see 35mm and more? I'm not aware off wich to choose, but is wide-angle the way to go? Is it possible to make a Converter style tilt/shift to put between camera and lens so you can put on just any lens in your bag? Or am I just thinking off something that wouldn't work?
QuoteOriginally posted by Ishpuini Quote
I would say so, mainly because of (Tilt/)Shift architecture. The classic offering for this was the K28/3.5 Shift (not tilt!), so I would expect an APS-C equivalent FOV in the new Pentax offering, hence 18mm. Tilt is not so important because of the large DOF you can typically expect at such focal lengths.

Anyway, the longer focal lengths exist from third parties (I have the Hartblei 65mm Super Rotator), the shorter just don't exist.

An adapter would be nice of course, but that would require glass to compensate for the increased registration distance in order to keep focus to infinite, and hence lengthen the focal length of the lens mounted by at least 1.4x I would think. So even if you would mount say a DA15, this would become a 21mm lens, i.e. a moderate wide angle only.

Anyway, I don't think the image circle of the DA lenses would allow shifting and tilting without vignetting. Perhaps FA and older glass could work though, but these are in even longer focal lengths. Current existing adapters are for Medium Format glass, and those are simply not available in focal lengths that are even remotely close to wide angle on APS-C.

Leaving three option: no t/s lens at all, having only one in production or changing for this type off work towards 645D.

A lot of tilt/shift discussion. Somehow my thoughts keep the same that this future isn't used as much on a APS-C sensor camera. These lenses are expensive, since difficult construction and low productionnumbers. Is it fair to say that this has to wait for a full frame camera or has to be moved to the 645D aerea?

Tilt/shift is a highly specialised field, and is not a cheap lens to create. From a business point of view, it would not be a big seller, even as much as the FA* 600 and 250-600 had limited market interest. Even for the 645 system it would be a financial stretch, but as with previous discussions, first thing's first - garner more interest in the Pentax system by developing more lenses with focal lengths the pros want to see, with performance they want to have.

So fast and reliable SDM and longer primes are a start, then consider some faster 20-24mm prime options. It's all in the air, but I'm hopeful dSLR and lens development is still clicking on all cylinders for Pentax - as much as the relatively small company is able to do with all the other bits of the photographic world they have their hands dipped into...

true but you never know unless you try it. With the hasselblad H system they have a T/S adapter but of course it there are a few limitations involved. If pentax could provide a weather resistant electronically integrated solution Pentax would be able to steal some market share from Hasselblad. And if pentax produces a 645 lens for portraiture an aperture of f/2 or faster* Hasselblad will lose a few more customers.

*providing it performs well of course, and they made it apochromatic it would be a total 'blad killer - the fastest lens for the H system is a 100mm f/2.2, and that lens isn't a full frame 645 lens.

Thanks for running the survey. I most wanted to vote for an ultra-wide 10 or 12mm prime with design emphasis on image quality and weight (rather than speed or price). No zooms here please, they are too slow, heavy, and sharpness varies unpredictably with different combinations focal length, aperture, and distance of focus.

If Sigma can make good lenses at good value prices, then Pentax or Ricoh should be able to do likewise. My bet is that if there was little to choose between the two, then most of us would buy Pentax. Of course, economies of scale come into it, but I guess this might be addressed by Pentax designing connection fittings for all the brands that Sigma currently produce for. If I had a Caniky I wouldn't be any more bashful about sporting a Pentax lens rather than a Sigma.

It's time to think big again.
