Alviso Marina County Park

Introduction

On August 23rd, 2025, I went to Alviso Marina County Park to test my new Tamron 50-400mm F/4.5-6.3 Di III VC VXD lens. However, I did not encounter many wildlife there. My personal conclusion is that the image quality from Tamron 50-400mm F/4.5-6.3 Di III VC VXD is similar to that from Tamron 28-300mm F/4-7.1 Di III VC VXD.
