TAMRON 25-200mm F/2.8-5.6 Di III VXD G2 (Model A075) Gets a Major Macro Boost with New Firmware Update

Tamron has released Firmware Version 3 for the 25-200mm F/2.8-5.6 Di III VXD G2 (Model A075) for Sony E-mount, and it's a genuinely useful upgrade for South African shooters who rely on this lens as their everyday walk-around zoom.

The headline change: the maximum magnification ratio at the 25-70mm focal range has been improved to 1:2 half-macro or greater — meaning you can now get noticeably closer to your subject and fill the frame with more detail than before. At the 35-50mm range specifically, the lens now achieves a maximum magnification ratio of 1:1.7, comfortably surpassing half-macro performance.

Why This Matters

For photographers who already love the A075 for its all-in-one versatility — from wide environmental shots right through to 200mm reach — this update adds genuine close-up capability into the mix. Think tighter product shots, more detailed nature and insect photography, and creative close-ups of textures and small subjects, all without swapping lenses or reaching for a dedicated macro.

Comparison: Before and After (at 50mm)

With Firmware Ver. 2 or older, the maximum magnification ratio at 50mm was 1:3.1. With Firmware Ver. 3, that improves to 1:1.7 — a substantial jump in close-focusing performance at one of the lens's most-used focal lengths.
