Price Comparison
When considering price, the EF 85mm f1.8 Portrait Lens is significantly more affordable than the TTARTISAN AF 27mm f2.8 lens. The EF 85mm lens retails for $77.59, while the TTARTISAN lens is priced at $159.99. This makes the EF 85mm lens about 51% cheaper than its competitor. For budget-conscious photographers, this price difference could be a decisive factor, especially for those who are just starting or looking to expand their lens collection without breaking the bank.
Design and Portability
The TTARTISAN AF 27mm f2.8 lens boasts a compact and ultra-lightweight pancake design, making it highly portable and ideal for travel. Photographers who value convenience will appreciate its small size, which allows it to easily fit into a camera bag or even a pocket. On the other hand, the EF 85mm f1.8 lens, while not as compact, offers a professional build that caters to serious portrait photographers. Its design emphasizes a large focus ring and a robust structure, but the added bulk may not be as travel-friendly as the TTARTISAN lens.
Focusing Mechanism
The EF 85mm f1.8 lens employs a fully manual focus mechanism, requiring photographers to engage in precise focus control. This design enhances creative freedom and adaptability, but it demands a level of expertise and practice to master. In contrast, the TTARTISAN lens features an STM (Stepping Motor) focusing system, which delivers smooth and quiet autofocus, making it more user-friendly, particularly for those who may not be as experienced in manual focusing. The ease of use with TTARTISAN’s eye recognition focus can make capturing fleeting moments much simpler.
Image Quality
In terms of image quality, the EF 85mm f1.8 lens is designed to produce superb image clarity and beautiful bokeh effects. Its construction includes six rounded aperture blades and advanced hybrid aspherical lens technology, which significantly reduces aberrations and glare. The result is a lens that excels in delivering artistic and high-quality portraits. While the TTARTISAN AF 27mm f2.8 lens does not provide specific details about its optical quality, its pancake design typically suggests that it is optimized for sharpness and clarity across various shooting conditions. However, the EF 85mm lens has a more established reputation for superior image quality, particularly in portrait photography.
Compatibility
The EF 85mm f1.8 lens is widely compatible with a range of Canon DSLR models, including the EOS Rebel series and the 5D Mark IV, among others. This extensive compatibility allows photographers to use this lens across various Canon bodies, making it a versatile choice for Canon users. In contrast, the TTARTISAN lens is designed specifically for Fuji X mount cameras, such as the Fujifilm XS10 and X-T4. This narrower compatibility may limit its appeal to those who use other camera brands or systems.
Features and Technology
The EF 85mm f1.8 lens is a manual focus lens with no electronic contacts, giving photographers complete control over their settings, including shutter speed, ISO, and aperture. This can enhance the learning experience for those looking to develop their photography skills. Conversely, the TTARTISAN lens includes modern features such as an independent clicked aperture ring for quick adjustments and a USB interface for firmware upgrades. These features add convenience and adaptability for photographers who prefer a more tech-savvy lens.
After-Sales Support
Lightdow, the brand behind the EF 85mm f1.8 lens, provides professional after-sales support, including maintenance and replacement during the warranty period. This assurance can provide peace of mind for buyers, knowing that they have support in case of issues. The TTARTISAN lens does not mention any specific after-sales service in the provided data, which may be a consideration for customers who value strong customer support and warranty options.
Which should you buy?
Choosing between the EF 85mm f1.8 Portrait Lens and the TTARTISAN AF 27mm f2.8 lens ultimately depends on your specific needs and preferences as a photographer. If you are a Canon user looking for an affordable, high-quality lens that excels in portraiture and offers manual control, the EF 85mm f1.8 lens is a compelling choice, especially given its lower price of $77.59. However, if you prefer a lightweight and compact lens that offers the convenience of autofocus and is designed specifically for Fuji X mount cameras, the TTARTISAN AF 27mm f2.8 at $159.99 may be the better option for your travel and street photography needs.
