I am going in full circle in finding a WR zoom. I currently don't have any of these zooms
- pentax da 16-50
- pentax da 16-85
- pentax da 18-135
There are many discussions that favor one over the other in between 16-85 and 18-135. I personally prefer 16-85 but in terms of traveling light with minimal weight, I will go for the 18-135 instead. But it is the last thing that I want to get both or all 3. It try to minimize zoom lens to a few as in 16-50 + 50-135 OR 16-85 + 50-135. I currently own 50-135 and I am extremely happy with 50-135 though AF speed can be better.
For someone who has 50-135, does it make any sense to get 16-50 instead of the two DC versions. The intended use is more serious work as in shooting events indoor and night scene shooting on the streets that is more demanding on speed usage. For casual shooting, I think both DC can do well for me but I will favor the 18-135 for lighter weight but for consistent picture quality across the full range, I will pick the 16-85. I have not made up my mind yet.
Thanks for all the valuable feedbacks. Am I right in thinking that it is more logical to pick 16-50 over the two if serious work is involved where picture quality weighs more into consideration. I am assuming buying a new copy without SDM failures.
Cheers,
