Canon RF-S18- vs TTArtisan Auto Focus

Overview of the Canon RF-S18-150mm and TTArtisan 35mm F1.8 Mark II

When comparing the Canon RF-S18-150mm F3.5-6.3 Telephoto Lens and the TTArtisan Auto Focus 35mm F1.8 Mark II, it is essential to recognize their distinct purposes and features. The Canon lens is priced at $569.00, while the TTArtisan lens is significantly more budget-friendly at $125.00. This difference of about 78% in price points to a divergence in their intended uses, with the Canon lens catering to a broader zoom range and versatility, while the TTArtisan lens focuses on portraiture and low-light performance.

Design and Build Quality

In terms of design, the Canon RF-S18-150mm is a high-magnification zoom lens tailored for APS-C cameras, which allows for a versatile shooting experience. Weighing in at an unspecified weight, it combines Canon's renowned optics with a design focused on capturing a variety of scenes, from landscapes to sports. Conversely, the TTArtisan lens has been upgraded to a lighter weight of 176g, making it compact and portable. This lens is specifically designed for Fuji X-mount cameras and excels in close-up photography, boasting a minimum focusing distance of 0.4m, which enhances its usability for detailed shots.

Focal Length and Versatility

The focal length of a lens plays a pivotal role in its versatility. The Canon RF-S18-150mm offers a zoom range from 18mm to 150mm, allowing photographers to cover standard to telephoto angles effortlessly. This extensive range makes it suitable for a myriad of photography styles, including landscapes, portraits, and action shots. In contrast, the TTArtisan lens has a fixed focal length of 35mm, which translates to an equivalent full-frame focal length of 53mm. While this limitation may seem restrictive, it is ideal for portrait photography and everyday shooting, offering a more intimate perspective without the need for zooming.

Aperture and Low-Light Performance

The aperture of a lens significantly affects its performance in low-light conditions. The TTArtisan lens boasts a maximum aperture of F1.8, making it highly advantageous for shooting in dim environments. This larger aperture not only allows more light to enter but also produces beautiful bokeh effects, enhancing the quality of portrait shots. On the other hand, the Canon RF-S18-150mm has a variable aperture ranging from F3.5 to F6.3, which, while suitable for general photography, may struggle in low-light situations compared to the TTArtisan. Thus, for those who prioritize low-light capability, the TTArtisan lens clearly outshines the Canon option.

Autofocus Capabilities

Autofocus performance is crucial, particularly for dynamic photography. The Canon RF-S18-150mm utilizes a lead screw-type STM, which ensures smooth autofocusing—an essential feature when shooting video or fast-moving subjects. The lens is equipped with 100% Dual Pixel CMOS AF coverage for APS-C sensors, promoting reliable focusing. The TTArtisan lens also features an upgraded autofocus system with a lead screw-type stepping motor, which provides smooth and quiet focusing. This ensures that both lenses offer solid autofocus performance, though the Canon lens has a slight edge due to its advanced AF coverage capabilities.

Image Stabilization

Image stabilization can significantly affect the quality of handheld shots, especially at longer focal lengths. The Canon RF-S18-150mm includes in-lens optical image stabilization, providing up to 4.5 stops of shake correction, which can be extended to 6.5 stops when paired with compatible EOS R series cameras featuring In-Body Image Stabilizer (IBIS). This feature is particularly beneficial for shooting in motion or in low light. The TTArtisan lens, however, does not mention any image stabilization features, making it less suitable for scenarios where camera shake could be an issue. Therefore, for those who often shoot in challenging conditions, the Canon lens is a more favorable choice.

Price and Value Proposition

Price is often a decisive factor when choosing between two lenses. The Canon RF-S18-150mm retails for $569.00, while the TTArtisan lens is available for a mere $125.00, making it about 78% cheaper. While the Canon lens offers more versatility and advanced features, the TTArtisan lens presents an excellent value for photographers who need a reliable, compact lens for portraits and everyday use. The significant price difference may sway budget-conscious consumers toward the TTArtisan, especially if their photography needs align with what the lens offers.

Which should you buy?

Deciding between the Canon RF-S18-150mm F3.5-6.3 Telephoto Lens and the TTArtisan Auto Focus 35mm F1.8 Mark II ultimately hinges on your specific photography needs. If you require a versatile zoom lens with strong performance across various shooting scenarios, the Canon lens is the clear winner with its extensive focal length and image stabilization features. However, if you're primarily focused on portrait photography, value portability, and low-light performance, the budget-friendly TTArtisan lens is an excellent choice. Consider your shooting style, budget, and the scenarios in which you typically find yourself when making your decision.
