Sony 100-400 F/4.5 Real World Review: Why I Want This Lens!

Steve from Backcountry Gallery here and in this video we’re reviewing the new Sony 100-400mm F/4.5 G Master lens. After spending time testing this lens in the field, I came away with a very different impression than I expected. On paper, it doesn’t completely dominate lenses like the original Sony 100-400 GM or even the Sony 200-600. But once I started shooting with it, there were a few things I kept noticing in the final images that really changed how I felt about this lens. In this review, we’ll cover: • Sharpness and real-world detail • Sony 100-400 F/4.5 vs Sony 100-400 GM • Sony 100-400 F/4.5 vs Sony 200-600 • Autofocus performance • 1.4x and 2x teleconverter testing • Rendering, bokeh, and image character • Internal zoom design • Stabilization • Handling and field use • Whether this lens is actually worth $4500 If you’re a wildlife photographer, bird photographer, or sports shooter trying to decide where this lens fits in Sony’s lineup, hopefully this review helps you figure out whether it deserves a spot in your bag. 📘 Sony Setup Guides: If you want help getting the most out of your Sony autofocus system for wildlife photography, bird-in-flight photography, subject detection, tracking, custom buttons, and field setup, check out my Sony setup guides here: Sony a1 setup guide: https://bcgwebstore.com/product/the-u...
