When Tamron announced their new 28-75 full frame lens designed for the Sony E-mount I had mixed feelings at first. Why would we need another lens in this focal range when we already have the amazing Sony 24-70 f / 2.8 G-master? On the other hand I was very excited to see a lens like Tamron starting to design lenses specifically for the Sony E-mount. This was great news on it's own, but why start with the 28-75? I love extreme wide-angle lenses. The 28-75 zoom range is a range I actually rarely use. I usually carry my 12-24 or 16-35, a 50mm prime and then a 70-300 or 100-400 meaning I skip the entire 24-70 or (or in Tamron's case the 28-75).
