Originally posted by jersey I think bigger thing now% is delivering up to date, fast AF lenses to pair with K-3 Mk III and not extending FF range.
I mean Pentax "action" camera has 2 (two) lenses that are able to bring the best out of new flagship, and only one is a pro lens that is relatively short for action shooting. 50-135 DA* and then something like 60-250 DA* or 100-300 or anything in that range with PLM drive makes more sense then next FF consumer lens in range that is at least partially covered by other consumer lenses.
I'm a little confused by this...
While I've certainly heard the calls for a revised 50-135 f2.8, and I think it's a good idea, particularly for the wedding/event folks, I often wonder how much overlap there would be between those customers and those for the DFA* 70-200 f2.8...
The recent DFA 70-210 f4 in many ways replaces the DA* 60-250 f4 (and is full-frame compatible without modifications).
I also don't see the difference, functionally, between a 100-300 and a 70-300, unless you're talking about something like a DA 100-300 f4, which you can have now with a 70-200 plus a DA1.4x converter. And I don't really see the point any more of limiting telephotos to APS-C image circles when there aren't really any advantages.
The rumor of the coming DFA 70-300 is that it will include PLM and optical stabilization. That means it won't be super cheap, but it does imply fast autofocus.
