Tamron 28-75mm f/2.8 Di III RXD
This lens is amazing. I have the Sony 24-70mm f4 and I thought it was a bit under-rated given my experience with the lens, which gave excellent results. More recently I got this Tamron lens, which really blows the Sony out of the water. The Tamrom is an inch longer than the Sony un-extended, as one might expect given the larger maximum aperature of the former. But in all other rpspects — build, performance and value — the Tamrom 28-75mm f2,8 is a superior lens.
Phillip Reeve says “The Tamron 2.8/28-75 Di III RXD is the first Tamron lens for mirrorless full frame cameras. The specs of the lens look spectacular and this holds true for the real lens. It is a f2.8 standard zoom lens that handles like the usual f4 counterparts.”
