Tamron 17-28mm F2.8 Di III VXD G2 will probably be launched later this yr. This new lens makes use of VXD drive to realize quicker AF pace and accuracy. The lens is anticipated to go on sale on the finish of the yr. (Beforehand there have been rumors that it was June)
Tamron only recently up to date the 28-75mm lens to version II. So I positively count on the huge angle zoom to be up to date too.
