Overview of the Lenses
The Canon RF-S18-45mm F4.5-6.3 Lens and the TTArtisan Auto Focus 35mm F1.8 Mark II APS-C Lens cater to different photography needs, making them unique choices for various users. The Canon lens is priced at $87.00, while the TTArtisan lens comes in at $125.00, making it about 43% more expensive than its counterpart. Both lenses are designed for APS-C cameras, but their focal lengths and features set them apart for specific shooting scenarios.
Image Quality and Performance
When it comes to image quality, the Canon RF-S18-45mm is designed with two Aspheric elements and Canon Super Spectra Coating, ensuring excellent image performance. This lens also features optical image stabilization, providing up to 4 stops of shake correction, which can be enhanced to 6 stops when paired with EOS R series cameras featuring In-Body Image Stabilizer. In contrast, the TTArtisan lens boasts a large F1.8 maximum aperture, which excels in low-light conditions and produces beautiful bokeh, making it a strong choice for portrait photography. While both lenses promise great image quality, the Canon lens's stabilization could give it an edge in dynamic shooting situations.
Versatility in Use
The Canon RF-S18-45mm offers a versatile zoom range of 18-45mm, making it suitable for a wide array of photography styles—from landscapes to portraits. This flexibility is particularly beneficial for photographers who prefer not to change lenses frequently. On the other hand, the TTArtisan lens, with its fixed 35mm focal length (equivalent to 53mm on full-frame), is more specialized and is optimized for portraiture. Therefore, if versatility is a priority, the Canon lens is the better option, while the TTArtisan lens caters to those focused on specific types of photography.
Size and Weight
Portability is a crucial factor for many photographers, especially those who often shoot on the go. The Canon RF-S18-45mm is compact and lightweight, specifically designed with APS-C sensors in mind, making it easy to carry around. The TTArtisan Auto Focus 35mm lens has also been made more compact than its predecessor, weighing just 176g, down from 199g. While both lenses are lightweight, the Canon’s retractable design allows it to fit easily into bags without taking up much space, enhancing its portability.
Autofocus Features
Autofocus performance can significantly affect shooting experiences, particularly in fast-paced environments. The Canon RF-S18-45mm features 100% x 100% Dual Pixel CMOS AF coverage for APS-C sensors, ensuring fast and reliable focusing. It employs a lead screw-type stepping motor (STM) for smooth and quiet autofocus, making it suitable for video shooting as well. Conversely, the TTArtisan lens also utilizes an upgraded STM and lead screw-type motor for improved autofocus precision. However, the Canon lens appears to have a slight edge due to its broader AF coverage, providing a more robust performance in various shooting conditions.
Pricing and Value
The Canon RF-S18-45mm lens is currently available for $87.00, offering significant value for those looking for a reliable standard zoom lens without breaking the bank. In comparison, the TTArtisan lens is priced at $125.00, making it about 43% more expensive. While the TTArtisan lens provides a larger aperture and is well-suited for portrait photography, the price difference may deter some users seeking a budget-friendly option. Overall, the Canon lens presents a great value proposition for general photography needs.
Target Audience
Each lens targets different groups of photographers. The Canon RF-S18-45mm is ideal for both novice and experienced photographers who require a versatile lens for various shooting scenarios. Its compact design and excellent image stabilization make it suitable for everyday use. On the other hand, the TTArtisan Auto Focus 35mm F1.8 Mark II is tailored for enthusiasts who prioritize portrait photography and low-light performance. This lens will particularly appeal to those who want a fast aperture for creative bokeh effects and close-up shots.
Which should you buy?
Deciding between the Canon RF-S18-45mm and the TTArtisan Auto Focus 35mm F1.8 Mark II ultimately depends on your specific needs as a photographer. If you're looking for versatility, portability, and excellent stabilization at a lower price point, the Canon lens is the clear winner at $87.00. However, if your focus is primarily on portrait photography and low-light performance, the TTArtisan lens, with its F1.8 aperture and enhanced autofocus features, may justify its higher price of $125.00.
