25-200mm A075 Firmware Ver. 3: Improved Half-Macro
The 25-200mm A075 firmware Ver. 3 is the latest firmware update for the TAMRON 25-200mm F/2.8-5.6 Di III VXD G2 (Model A075) for Sony E-mount cameras. Released on July 29, 2026, the update significantly improves the lens’s close-up performance by increasing the maximum magnification ratio at focal lengths from 25mm to 70mm to 1:2 or greater.
At 35-50mm, the lens can now achieve a maximum magnification ratio of 1:1.7, exceeding half-macro performance. This allows photographers to capture small subjects with greater detail and a larger image size in the frame.
What is new in 25-200mm A075 firmware Ver. 3?
The main improvement in 25-200mm A075 firmware Ver. 3 is enhanced close-up performance.
After updating the lens:
The maximum magnification ratio is 1:2 or greater from 25-70mm.
At 35-50mm, the maximum magnification ratio reaches 1:1.7.
The improved magnification makes it possible to capture subjects larger in the frame.
The update expands the creative possibilities of the 25-200mm F/2.8-5.6 Di III VXD G2 for close-up photography.
This is more than a compatibility update. It directly improves what photographers can capture with the lens, particularly when photographing small subjects from close distances.
Improved half-macro performance
The A075 was already designed as a versatile all-in-one zoom, covering focal lengths from 25mm wide angle to 200mm telephoto.
With firmware Ver. 3, its close-up capability becomes even more useful.
The update provides a maximum magnification ratio of 1:2 or greater throughout the 25-70mm range. At 35-50mm, the lens achieves a maximum magnification ratio of 1:1.7.
A 1:2 magnification ratio is commonly described as half-macro performance because the subject can be reproduced at approximately half its actual size on the camera’s sensor.
The A075 can now provide this level of magnification across a useful range of focal lengths rather than at only one specific focal length.
25mm to 70mm close-up range
One of the biggest advantages of the firmware update is the breadth of the improved magnification range.
Firmware Ver. 3 improves the maximum magnification ratio at focal lengths from 25mm through 70mm. This gives photographers more flexibility when composing close-up images.
At the 25mm wide end, photographers can work close to subjects while maintaining a wider perspective.
Moving toward the middle of the zoom range provides more working flexibility and can make it easier to fill the frame with smaller subjects.
This is useful for subjects such as flowers, food, accessories and everyday details where photographers may want to switch between a wider environmental view and a tighter close-up without changing lenses.
1:1.7 magnification at 35-50mm
At focal lengths between 35mm and 50mm, the A075 can achieve a maximum magnification ratio of 1:1.7 with firmware Ver. 3.
This exceeds the 1:2 half-macro level.
The increased magnification allows smaller subjects to occupy more of the frame while retaining the flexibility of the zoom lens.
For photographers who enjoy close-up photography, this means the A075 can be used for a wider variety of subjects without requiring a dedicated macro lens for every situation.
What can you photograph with the A075?
The improved close-up performance opens up additional creative opportunities.
Flowers and plants
Flowers, leaves and small plants are natural subjects for close-up photography.
The improved magnification allows photographers to capture details in petals, textures and patterns while maintaining the convenience of a zoom lens.
Food and tabletop photography
The 35-50mm range can be particularly useful for food and tabletop subjects.
The ability to achieve 1:1.7 magnification makes it easier to fill the frame with smaller objects without physically moving as close as would be required with a conventional standard zoom.
Small products and accessories
The improved magnification can also benefit product and detail photography.
Small accessories, cameras, watches, stationery and other objects can be photographed with greater frame coverage.
Travel details
The A075 is designed as an all-in-one zoom, making it useful for travel photography.
With the firmware update, the same lens can move from wide-angle scenes to closer details without requiring a lens change.
Firmware version history for the A075
The 25-200mm F/2.8-5.6 Di III VXD G2 has received firmware updates that have expanded its capabilities and software compatibility.
Firmware Ver. 3
