Tamron MA23F25V 2/3" 25mm F2.4 Manual Iris C-Mount Lens, Compact Design, 8 MP Rated

Typically 3-4 days
Current Stock:


The new MA23F lens series is made for 2/3” image sensors with up to 8 Megapixel resolution and a 2.74µm pixel pitch. It comes in focal lengths of 8, 25 and 35mm. Compared to the previous generation of 2/3” lenses, this new series offers improvements in terms of resolution, distortion and size.

Its rugged mechanical design and the compact size with a body diameter of only 29mm are further additional features, which make this lens series the perfect choice for various, sophisticated applications.

Key Features

1. High Resolution and Contrast Unrivaled in the Industry
The new models are compatible with 2/3" imagers, supporting 2.74um pixel-pitch and max 8-mega pixel resolution, offering resolution and contrast outperforming other Ø29mm machine-vision lenses.

2. Industry-leading Low Distortion (TV Distortion)
Tamron's state-of-the-art optics technology significantly reduces TV distortion compared with previous models. Specification: MA23F08V: -0.6% / MA23F25V: -0.01% / MA23F35V: 0.04%

3. High-Quality Performance at Close-up Distances
A new comprehensive lens design assures high contrast and resolution at commonly used close-up distances.

4. Rigorous Inspection of Image Quality
Thorough inspection is performed on the imaging resolution from the center to the periphery, warranting high-contrast and high-resolution without unbalanced blurring throughout the entire lens view.

5. New Robust Mechanism for Anti-Vibration and Anti-Shock
A newly designed mechanism improves on anti-vibration and anti-shock performance compared with previous models, limiting the optical (image) deflection to less than 10um even for the severe impact of vibrations and shocks of max 10G of magnitude.
*Vibration frequency 10-60Hz (amplitude 0.75mm), vibration frequency 60-200Hz (acceleration 100m/s2), and the number of cycles: 50 cycles.

6. A Common-use Setscrew is Attached as a Standard Accessory
A lock-screw provided with the models can be replaced with any embedding-type setscrew. This further reduces the overall diameter of the lens barrel for more compact installation.
