Generally, travel lenses are meant to cover a wide range of focal lengths to allow you to be able to photograph most things you are likely to encounter. On the other hand, when you go for a large focal length range, that often means sacrificing wide apertures for low-light situations and sharp image quality. This lens might be able to give you the trifecta of reach, aperture, and sharpness, however.
Coming to you from Dustin Abbott, this great video takes a look at the Tamron 35-150mm f/2-2.8 Di III VXD lens for travel photography. The 35-150mm f/2-2.8 is a remarkable lens, offering an extremely wide maximum aperture despite its wide focal length range and impressive image quality. Of course, to get all those things, it takes a lot of glass, and the two downsides that equates to are a fairly high price (compared to something like a 24-300mm superzoom) and a heavy footprint, at 41.1 oz (1,165 g). That is something that is definitely worth considering, as it could become a bit tiring to carry around such a lens if you plan on going for long days out on vacation. Nonetheless, it is quite a unique lens that offers an impressive combination of features. Check out the video above for the full rundown from Abbott.
