The lens features XR (Extra Refractive Index) glass for improved optical performance and reduced aberrations.

Provides consistent performance and exposure across the entire zoom range.

Constant f/2.8 Aperture

Enhances optical quality by reducing chromatic aberrations and improving image clarity.

XR (Extra Refractive Index) Glass

Ensures a stable lens length during focusing and allows for easier handling.

Internal Focusing (IF) System

Ideal for travel and on-the-go photography without compromising performance.

Compact and Lightweight Design

The Tamron A16 AF 17-50mm is a **zoom lens** built for **APS-C format DSLR** cameras in the **Nikon F mount**. Its **17–50mm focal length range** covers a broad standard zoom spread, while the **constant f/2.8 maximum aperture** ensures consistent exposure and depth-of-field control whether you're at the wide or short telephoto end of the range. Autofocus and manual focus are both supported, offering flexibility across different shooting scenarios. Weighing just **430g**, it strikes a practical balance for shooters who want a fast standard zoom without excessive bulk. The **67mm filter thread** makes it straightforward to pair with popular filter sizes. One consideration for buyers is the **absence of image stabilization** — a factor worth weighing if you frequently shoot handheld in low-light conditions or capture video without a stabilized body.

Maintains a maximum aperture of f/2.8 throughout the entire zoom range, ensuring consistent exposure and depth of field control whether shooting at 17mm or 50mm.

Covers wide-angle to short telephoto on APS-C, making it a versatile everyday zoom for travel, events, and general photography.

17-50mm Focal Range

Built specifically for APS-C format sensors, keeping the lens compact and lightweight compared to full-frame equivalents with similar specifications.

APS-C Optimized Design

Supports both autofocus and manual focus modes, giving shooters the flexibility to switch depending on the subject or shooting situation.

Autofocus with Manual Override

The lens focuses internally, meaning the front element does not rotate or extend during focusing — useful when using polarizing or graduated filters.

Internal Focus (IF)

At 430g, the lens is light enough for comfortable all-day carry without sacrificing the constant f/2.8 aperture.

430g Practical Weight

Uses a widely available 67mm filter size, making it straightforward to source compatible UV, polarizing, and ND filters.

67mm Filter Thread

Fits a broad range of Nikon APS-C DSLRs, including the D3000, D5000, D7000 series and beyond.
