Originally posted by VoiceOfReason I simply want a nice zoom to get me to 600+ and I would think they could update that lens and do it at a lower cost. If they were able to do it and sell them for 3-5k they probably couldn't keep up with demand. It's a big gap in the lineup to me.
With the 560 f5.6 in the lineup, and apparently not all that popular at 4k, I'm just not sure that lens would have a market. A DFA* 250-600 is a birder/wildlife lens and there aren't a whole lot of people clambering for a Pentax body if they are pro wildlife/bird shooters. Pentax AF just isn't there.
Now if the K1iis or whatever comes out with 99 3d AF points and 27 at f2.8, 28MP and 8 fps (@ what 4k-ish?), then maybe you could see where they would be going. Though I think you would first see a remake of the F/FA* 600 f4 and a 300 f2.8. if THOSE lenses and a body with the aforementioned specs come out, then yeah, maybe a 10k rework of 250-600 is in the near future.
For now, I think Pentax sees themselves as a niche landscape/portrait/fashion demographic. Those kind of shots don't need a 250-600.
