According to the source of Nikon Rumors, Tamron is about to announce a new lens. It will be an 18-400mm f/3.5-6.3 Di II VC HLD, a zoom lens designed for APS-C DSLR bodies. Going from a wide angle to a telephoto zoom, this will be a lens that gives you a variety of possibilities.
There are a couple of images of Tamron 18-400mm f/3.5-6.3 leaked on Nikon Rumors, but for now we don’t have more information about the new lens. However, from what you can see, it’s not a really fast lens. Just like Tamron 16-300mm, it will feature a variable aperture between f/3.5 and f/6.3. Still, it can be useful for travels or photo walks when you don’t want to carry several lenses with you. I assume it will also be affordable, considering the features.
As for the sharpness, the users report different experiences with the Tamron 16-300, so I’m not sure what we can expect. Some users say they couldn’t get a sharp photo with this lens, while the others recommend it for sharpness. I guess we should wait and see. As soon as we have more info about the new lens, we will inform you.
