Canon RF-S18- vs TTARTISAN

Pricing Comparison

The Canon RF-S18-150mm F3.5-6.3 Telephoto Lens is priced at $569.00, while the TTARTISAN 40mm f2 Lens for Z Mount costs $168.00. This means the TTARTISAN lens is about 70% cheaper than the Canon lens. For photographers on a budget, the significant price difference could make the TTARTISAN a more appealing option, especially for those who do not require a zoom lens and prefer a prime lens for specific photography styles.

Build Quality

The TTARTISAN 40mm f2 Lens features a premium build crafted from 5052 aerospace aluminum, weighing just 167g, making it ultra-portable and easy to carry. In contrast, the Canon RF-S18-150mm lens is designed for versatility but does not specify its build material. While both lenses are likely durable, the TTARTISAN's lightweight and sturdy construction may be more beneficial for travel photographers who prioritize portability without sacrificing quality.

Lens Type and Versatility

The Canon RF-S18-150mm is a high-magnification zoom lens with a range of 18-150mm, offering both standard-angle and telephoto capabilities. This makes it versatile for various photography styles, from landscapes to portraits. In comparison, the TTARTISAN 40mm f2 is a prime lens, providing a single focal length of 40mm. While prime lenses often deliver superior image quality, the lack of zoom in the TTARTISAN may limit its versatility for those who prefer to shoot in varying conditions without changing lenses.

Autofocus Performance

The Canon RF-S18-150mm boasts a lead screw-type STM that provides smooth autofocus, particularly useful for video shooting. It also features dual pixel CMOS AF coverage, which enhances its autofocus performance for both APS-C and full-frame sensors. The TTARTISAN lens, meanwhile, employs an STM motor and includes face/eye tracking capabilities for precise autofocus. Both lenses offer advanced autofocus systems, but the Canon may have an edge in terms of versatility due to its dual pixel technology, which is particularly beneficial for video creators.

Low Light Performance

When it comes to low-light performance, the TTARTISAN 40mm f2 lens shines with its bright f/2 aperture, allowing for stunning clarity and vivid color reproduction in dim environments. This makes it an excellent choice for nighttime photography or indoor settings. The Canon RF-S18-150mm, with its variable aperture range of f/3.5-6.3, may struggle more in low-light conditions compared to the constant f/2 of the TTARTISAN. For photographers who often shoot in less-than-ideal lighting, the TTARTISAN offers a clear advantage.

Image Stabilization

The Canon RF-S18-150mm features in-lens optical image stabilization that provides up to 4.5 stops of shake correction, which can be extended to 6.5 stops when paired with compatible EOS R series cameras. This advanced stabilization technology is particularly useful for handheld shooting, allowing for sharper images in challenging conditions. The TTARTISAN lens does not mention any image stabilization features, which may be a drawback for users looking to shoot without a tripod, especially in low-light situations.

Intended Use Cases

The Canon RF-S18-150mm is marketed as a versatile all-around lens suitable for landscapes, portraits, sports, and video, making it an excellent choice for those who want a single lens to cover various scenarios. In contrast, the TTARTISAN 40mm f2 lens is better suited for photographers who favor street photography, portraits, and low-light situations due to its compact size and bright aperture. Each lens caters to different photography styles, so the choice largely depends on the user's specific needs.

Which should you buy?

Choosing between the Canon RF-S18-150mm F3.5-6.3 Telephoto Lens and the TTARTISAN 40mm f2 Lens for Z Mount ultimately hinges on your photography style and budget. If you require versatility and plan to shoot in a wide range of environments, the Canon lens offers a broader zoom range and superior image stabilization. However, if you're looking for a lightweight, affordable option that excels in low light and provides a prime lens experience, the TTARTISAN is a compelling choice. Each lens has its strengths, making them suitable for different types of photographers.
