Is the tamron 70 180mm f 2 8 di iii vxd good for travel?
Not really. The 70-180mm f/2.8 is a telephoto zoom, and the travel guide asks for something that covers wide to short telephoto so one lens handles most of a trip. This one starts at 70mm, so it won't take in a street, a meal or a wide landscape.
It also has no stabilisation. The guide's advice on image stabilisation matters for dim churches and interiors, and this lens doesn't help there. Its size and weight aren't listed on the site, so check those before you decide.
If you want it for a specific job, like sports or wildlife on a trip, it can work. For general travel, I'd look at a versatile zoom instead. The Tamron 70-180mm Di III VC VXD G2 page is a newer version whose name includes VC, but the site has little more on it yet.
