Originally posted by DaveBlack I would love to see a DA*10-16 f4.0 and a DA*135-400 f4.0 to complete the DA* zoom lineup. Your list had a too slow non * len 135-400 so I didn't vote for it. Canon has a real great L100-400 f4.0 lens so Pentax could have one. The long DA* lens 135-270 is fast enough but doesn't have the reach for wildlife photography. It would be a real nice night football lens.
We really need a fast WR high-end normal lens. Either a DA*28/f1.8 or a DA*30/f1.4. Then Pentax doing its odd things how about a DA*29/f1.7. It could be the crop sesnor equalivent of the FA43 Limited.

For the long end I looked at Falk's blog and his artikle on telelenses:
Falk Lumo: A hypothetical Pentax DFA* 500mm F5.6 ED(IF) SDMii You see that with some margin bigger lenses get heavy and expensive. As we all know. 400/f4 is heavier and with bigger filterthread and more expensive then 270mm/f2.8!
The Canon lens you are referring to is 100-400 f4.5-5.6 so that is not at all the lens you are thinking about. I'm guessing that your lens would costs like $ 6000 and there is no market for in Pentaxland. There is a Nikkor 200-400mm/f4 costing 5775 euro.
Again I'm plugging the 1.4xTC with the 135-270mm/f2.8 lens since that is a good version of Canon's lens as well and faster since it is f4 all over.
Your 11-16, that is sort of Tokina lens, I just forgot about it. Maybe this would make a good successor for 12-24 in a WR version.
Well there is always 31mm/f1.8 as fast in that range. There could be something just under that line, but if it is expensive, who's gonna buy? You are looking at $ 1500 and more I think. In the survey the 24mm/f2 is popular, but having another lens inbetween this 24 and 31 is asking a lot.
