The question by the OP wasn't about how the m.zuikio 40-150 telephoto zoom compares to other telephoto zooms, but whether he "needs" a telephoto zoom at all in order to visit Sri Lanka. I say he doesn't. If he hasn't found a use for such a lens living in his home country, I don't see why he will suddenly discover this "need" in Sri Lanka.
For travel you do need the ability of the tele lens.
Most times it's up close and personal in Asian countries, but often there's some typical local scene, such as a fisherman casting nets, that can't be reached at all by "zooming with your feet", so the 40-150mm style of lens makes that now an available scene, otherwise it would be just a dot in the image with a 14-42 lens.
The totally ideal lens to travel with is the 14-150mm or superzoom equivalent in any camera, that makes capturing those small swiftly changing scenes in Asia so much easier to capture. First trip to Japan in 2009 I used a Panasonic LX3 with its 24-60mm equivalent range, got many great shots but then quite often I had to call on my wife to capture some detail and her 24-300mm equivalent pocket camera saved the day.
On the second 2011 Japan trip I was more sensible and took E-PL1 and 14-150mm and 9-18mm and despite thinking that I would be using the 9-18mm most, it was the 14-150mm that got 90% or more of the shots, and the ease of transition from wide to tele made life so easy to capture what took my interest.
Next Japan trip (I wanna go back! - Hey, maybe Autumn this year?) it will be two E-PL5 bodies, one with the usual 14-45mm lens plus change to 9-18mm occasionally, and the other body with 45-150mm "glued" to it. Both in an easy to reach bag and each camera with hood on and lens cap off so are ready to use quickly. Way better than lens swapping and also then have a backup body if one goes bananas.
Using just the base kit lens focal lengths of 14-42 or somesuch is so darn limiting and frustrating, you do miss so many great photo opportunities.
