Review on Tamron 70-300mm F/4.5-6.3 Di III RXD Lens for Sony Mirrorless Full Frame/APS-C E-Mount, Black (6 Year Limited USA Warranty) by Jarrett Young

A well designed and versatile long range lens. Tamron's 70-300mm full-frame lens lengthens and enlarges images. I shoot with the Sony A7-III, the autofocus is fast, quiet and precise. Only wish is the zoom lock - the weight of the lens hanging from the strap in the campaign will see it slowly extend into the 300mm range. The excellent 28-75mm f/2.8 is a bit stiffer and doesn't have this (minor) problem. You will be so pleased with this lens that you won't believe you bought it for less than $500. I'm so glad I updated! Pictures: This is the same photo. I cropped the copy to show details of the ranger station at the top of the mountain. The blue tint is because I'm seven miles from the subject. In the hands, but with support on the deck rail.
