The Tokina AT-X Pro 12-24mm f/4 DX II is an ultra-wide angle zoom lens designed specifically for APS-C DSLRs, making it a fantastic option for Canon EF mount users looking to capture expansive landscapes, architecture, or just to get a unique perspective on their subjects. Its 12-24mm focal length translates to approximately 19-38mm in 35mm terms, making it quite versatile within the context of wide-angle photography.
One of the standout features of this lens is its constant f/4 aperture. This allows for consistent exposure throughout the zoom range, which is particularly beneficial for landscape photographers who often shoot at various focal lengths while maintaining the same depth of field and exposure settings. The lens also employs a number of special elements to minimize chromatic aberration and distortion, which are common issues at wide angles. The build quality is robust, featuring a solid metal mount and a weather-sealed body, making it suitable for outdoor use in various conditions.
When it comes to image quality, the Tokina AT-X Pro 12-24mm f/4 DX II delivers impressive sharpness, particularly in the central area of the frame, even when shot wide open. You will find that edge performance is commendable as well, although it doesn't quite match the center sharpness at the extremes of the focal range, especially when wide open. The lens handles flare reasonably well, thanks to its advanced multi-coating, making it a good choice for bright outdoor scenes.
However, there are some downsides to consider. The autofocus performance is not the fastest on the market, which could be a limitation for those shooting fast-moving subjects or unpredictable scenes. Additionally, the lens is a bit bulky compared to its counterparts, which might be a concern for those looking for a lightweight, travel-friendly option.
The Tokina AT-X Pro 12-24mm f/4 DX II is a solid choice for Canon EF mount users who require a dependable ultra-wide-angle lens for landscape and architectural photography. While it may not have the fastest autofocus nor is it the lightest option around, its overall performance, build quality, and affordability make it a compelling choice for both amateur and semi-professional photographers. If you prioritize image quality and durability and don't mind the added weight, this lens can significantly enhance your photographic toolkit.
