Tamron's fast SP 24-70mm F/2.8 VC lens is professional class. I find its sharpness to be perfect for my landscape photography.

The world’s only full-frame F/2.8 standard zoom with image stabilization (VC). Portraits. Landscapes. Studio Shoots. This is the lens for them all. Capture the finest details of your images in precisely the way you have always wanted.

The A007 is a high-quality, highly functional, high-speed standard zoom lens covering the 24‒70mm focal range. It includes both Tamron’s proprietary VC (Vibration Compensation) image stabilization to reduce shake and its USD (Ultrasonic Silent Drive) motor, enabling speedy, silent autofocusing.

This SP (Super Performance) series lens makes full use of specialized glass elements in its lens layout, designed with top priority on image quality, including three LD elements and two XR (Extra Refractive Index) glasses.
