The TTArtisan 11mm f/2.8 is a unique lens designed for Canon RF mount cameras, particularly appealing to landscape, architecture, and astrophotography enthusiasts. This ultra-wide-angle lens offers a compelling combination of a fast aperture and a broad field of view, making it a versatile option for various shooting scenarios.
The build quality of the TTArtisan 11mm f/2.8 is impressive for its price point. It features a robust metal construction that gives it a premium feel while still being relatively lightweight. The lens is well-sealed, providing a layer of protection against dust and moisture, which is a significant advantage for outdoor shooting. The focus ring is smooth and well-damped, allowing for precise adjustments, though it is entirely manual, which may not appeal to everyone.
Optically, the TTArtisan 11mm f/2.8 performs admirably. It provides sharp images across the frame, even when shot wide open at f/2.8. The color rendition is natural, and blooming or flare is minimal thanks to its multi-layer coating. Users can expect satisfying contrast and clarity, which are essential for capturing detailed landscape shots or the intricate architecture of buildings. However, like many ultra-wide lenses, it does exhibit some distortion, particularly at the edges. This can often be corrected in post-processing but is something to keep in mind if you're shooting straight lines, like architectural subjects.
This lens features a minimum focusing distance of just under 25 cm, which opens up opportunities for creative close-up shots, with an impressive depth of field and the ability to include lots of context in the background. The f/2.8 aperture provides decent low-light shooting capabilities, but it may struggle a bit compared to faster wide-angle lenses if you're looking for shallow depth of field effects. The lens also lacks autofocus, which might be a disadvantage for event or capture-and-go photographers.
Overall, the TTArtisan 11mm f/2.8 is a solid choice for photographers looking to expand their creative toolbox, especially within the Canon RF ecosystem. While it has some limitations, particularly due to the lack of autofocus and slight edge distortion, its build quality, optical performance, and versatility make it a commendable option for those willing to embrace manual focus. Whether you're exploring landscapes, capturing architectural details, or delving into astrophotography, this lens can deliver striking results without breaking the bank.
