Originally posted by Marktax I find travel photography to be highly situational, especially somewhere I have not been before.
+1. When I travel to a new place, I want to ready for anything. My default (ie basic) travel lens is the DA18-250mm with a fast prime (eg 50 mm f1.4) in my jacket pocket for low-light sceneries. It is now more than 8 years that I travel overseas a couple of times per year, and the DA18-250mm (+ my VL58mm f1.4) is my basic travel kit.
When I know already the destination (eg I have been there before), I am more 'choosy' and tend to use primes.
The DA16-85mm definitely ticks a lot of boxes, incl. its wide focal length range. Cons are low light, a lack of reach (above 85 mm) and the lens size IMHO.
Hope that the comment may help.
