This lens is designed for Fujifilm X-mount APS-C mirrorless cameras, providing a 41mm equivalent focal length, which is versatile for various photography genres.
Its bright f/2.8 maximum aperture is suitable for low-light conditions and offers good control over depth of field. With a pancake form factor measuring less than 3cm thick, it is incredibly portable, making it an ideal choice for everyday shooting and travel photography.
Image Quality Comparison
In terms of image quality, the Sigma 30mm F1.4 stands out with its larger f/1.4 aperture, which excels in low-light environments and allows for more pronounced background blur. The nine rounded diaphragm blades contribute to smooth bokeh, making this lens a strong contender for portrait and artistic photography.
On the other hand, the TTartisan 27mm F2.8 offers a more modest f/2.8 maximum aperture. Although it may not deliver the same level of low-light performance as the Sigma, it still utilizes a well-designed optical structure that includes 6 elements in 5 groups. This construction helps to produce sharp images while controlling chromatic aberrations, making it a solid choice for general photography.
Autofocus Performance
The Sigma 30mm F1.4 features a stepping motor that provides fast and accurate autofocus, which is especially useful for video work. This performance can be critical for capturing moving subjects or for achieving precise focus in dynamic shooting conditions.
The TTartisan 27mm F2.8 also includes autofocus capabilities, along with manual focus override for added flexibility. However, details such as the speed and accuracy of its autofocus system are not highlighted, suggesting that while it is functional, it may not match the Sigma's performance in fast-paced scenarios.
Build and Design
The Sigma 30mm F1.4 has a compact design but is slightly bulkier than the TTartisan. It is constructed with a focus on durability and is designed for high performance, making it suitable for professional use. The included accessories such as a lens hood and front and rear caps enhance its usability and protection.
Conversely, the TTartisan 27mm F2.8 is designed as a carry-anywhere lens, with a pancake form factor that allows it to be mounted on cameras without adding significant bulk. Its lightweight design makes it well-suited for travel, but it may not offer the same level of ruggedness as the Sigma lens.
Versatility in Photography
The Sigma 30mm F1.4 is particularly versatile for various photography styles, from portraits to landscapes, due to its large aperture and focal length. It serves well in both low-light conditions and for creating depth of field, making it a favorite among creative photographers.
On the other hand, the TTartisan 27mm F2.8 lens, with its 56° angle of view, is also adaptable to various genres, including street and close-up photography. While it may not have the same low-light prowess, its compact size and lightweight design allow photographers to easily carry it for spontaneous shooting opportunities.
Price Comparison
The price difference between the two lenses is significant. The Sigma 30mm F1.4 is priced at $419.00, while the TTartisan 27mm F2.8 is priced at $159.99, making the latter about $259.01 cheaper. This substantial price gap can be a deciding factor for many photographers, especially those on a tighter budget.
While the Sigma lens justifies its higher price with enhanced features and superior image quality, the affordability of the TTartisan lens makes it an attractive option for hobbyists or those looking for a reliable everyday lens without a hefty investment.
Which should you buy?
Deciding between the Sigma 30mm F1.4 Contemporary DC DN Lens and the TTartisan 27mm F2.8 Autofocus Lens ultimately depends on your photography needs and budget. If you prioritize low-light performance, image quality, and professional-grade features, the Sigma is worth the investment at $419.00. However, if you are looking for a lightweight, portable lens that offers decent performance at a much lower price point of $159.99, the TTartisan is an excellent choice. Each lens has its strengths, so consider your specific requirements and shooting style when making your decision.
