The former is priced at $65.69, while the latter retails for $159.99, making the EF/EF-S lens about 59% cheaper than the TTArtisan. Both lenses target different photographic needs, showcasing distinct features that cater to varying user preferences.
Target Audience
The EF/EF-S 420-800mm F8.3 lens is designed for photographers who seek to capture distant subjects, such as wildlife and landscapes, thanks to its impressive zoom range. In contrast, the TTArtisan AF 27mm F2.8 lens is aimed at Fujifilm users looking for a compact, versatile lens that excels in everyday photography with its f/2.8 aperture. This significant difference in target audience highlights the distinct purposes these lenses serve, making the choice dependent on specific photographic styles.
Build Quality and Design
The EF/EF-S 420-800mm lens features a fully manual focus design, which allows for precise adjustments but requires a deeper understanding of photography. It emphasizes stability and durability, catering to photographers who value manual control. The TTArtisan AF 27mm lens, however, boasts a more modern design with an STM stepping motor for smooth focusing, making it user-friendly for those who prefer automatic functions. The difference in build quality and design reflects the philosophies of the brands—Lightdow focusing on manual engagement, while TTArtisan leans towards convenience.
Aperture and Light Gathering
When it comes to aperture, the EF/EF-S 420-800mm lens has an aperture range from f/8.3 at 420mm to f/16 at 800mm. This range limits low-light performance but is sufficient for outdoor shooting in bright conditions, particularly suited for telephoto work. On the other hand, the TTArtisan AF 27mm lens features a constant f/2.8 aperture, allowing for better light gathering and creating a pleasing bokeh effect. This makes it ideal for low-light situations and portrait photography. The difference in aperture capabilities is crucial for photographers considering shooting conditions.
Focusing Mechanism
The EF/EF-S 420-800mm lens operates entirely on manual focus, which can be both a challenge and an opportunity for photographers who wish to hone their skills. This design allows for creative control but requires a steady hand and patience. Conversely, the TTArtisan AF 27mm lens incorporates an eye-detection autofocus system, enhancing usability and ensuring that subjects are captured sharply and accurately. The contrasting focusing mechanisms cater to different skill levels and preferences, with the TTArtisan lens being more suitable for those who favor simplicity in operation.
Compatibility
In terms of compatibility, the EF/EF-S 420-800mm lens is designed for Canon EOS cameras, including a wide range of models from the Rebel series to the professional 1D X series. This extensive compatibility makes it a versatile choice for Canon users. On the other hand, the TTArtisan AF 27mm lens is specifically built for Fujifilm X-mount cameras, ensuring seamless integration with models like the X-T10 and X-T4. The choice of lens will heavily depend on the camera system you own, making compatibility a vital factor in the decision-making process.
Price Consideration
The EF/EF-S 420-800mm lens is priced at $65.69, while the TTArtisan AF 27mm lens comes in at $159.99. This price difference of $94.30 makes the EF/EF-S lens approximately 59% less expensive. For budget-conscious photographers, this significant cost saving could influence the decision, particularly for those who are starting in photography or looking to experiment without a hefty investment. However, those seeking specific features and superior technology may find the price of the TTArtisan justified.
Which should you buy?
The decision between the EF/EF-S 420-800mm F8.3 lens and the TTArtisan AF 27mm F2.8 lens boils down to your photographic needs and preferences. If you're a Canon user requiring a budget-friendly telephoto lens to capture distant subjects, the EF/EF-S lens offers great value at a lower price point. However, if you own a Fujifilm camera and prioritize a compact, versatile lens with autofocus capabilities for everyday shooting, the TTArtisan lens might be worth the investment despite its higher cost. Ultimately, the right choice will align with your photographic style and intended use.
