Price Comparison
The TTARTISAN AF 27mm f2.8 is about 9% cheaper than the OM SYSTEM Olympus M.Zuiko Digital 40-150mm, priced at $159.99 compared to $175.99. For photographers on a budget, this price difference may be a significant factor in their decision-making process. While both lenses fall within a similar price bracket, the lower cost of the TTARTISAN lens could make it more appealing for casual users or those looking to expand their kit without breaking the bank.
Design and Portability
When it comes to design, the TTARTISAN AF 27mm f2.8 excels with its ultra-compact pancake style, making it exceptionally portable. This lens is designed for on-the-go photographers who value travel-friendly gear. The OM SYSTEM lens, while still portable, has a more traditional zoom lens design, which can be bulkier due to its larger focal length range of 40-150mm. Therefore, the TTARTISAN is likely the better choice for users prioritizing a lightweight and compact setup.
Focal Length and Versatility
The OM SYSTEM Olympus lens offers a focal length of 40-150mm, providing a versatile zoom range suitable for various photography styles, from portraits to landscapes. In contrast, the TTARTISAN lens has a fixed focal length of 27mm, which is more suited for street photography and everyday shots. The broader zoom range of the OM SYSTEM lens allows for more creative flexibility, making it ideal for photographers who often change their shooting style.
Aperture and Low-Light Performance
The OM SYSTEM Olympus lens features a maximum aperture of F4.0-5.6, which may limit its performance in low-light situations compared to the TTARTISAN's faster F2.8 aperture. A lower f-stop indicates that the TTARTISAN can allow more light to hit the sensor, making it a better option for shooting in dimly lit environments. This advantage can lead to sharper images and less noise in low-light conditions, which is crucial for many photographers.
Autofocus Technology
The TTARTISAN AF 27mm f2.8 incorporates a stepping motor (STM) for autofocus, which allows for smooth and quiet focusing, ideal for both photography and video recording. The OM SYSTEM lens features High-Speed Imager AF (MSC), which also promises fast and reliable autofocus. However, the eye recognition focus technology in the TTARTISAN lens enhances its capability for capturing sharp images of moving subjects, making it a strong contender for action shots and portraits.
User Experience and Features
The OM SYSTEM lens has a straightforward design, focusing on delivering a reliable zoom experience without many bells and whistles. Its features cater well to those who appreciate simplicity. In contrast, the TTARTISAN lens is designed with a clicked aperture ring, providing users with a more tactile shooting experience. Additionally, it includes a USB-C interface for firmware upgrades, allowing for improved performance over time. These features may appeal to tech-savvy photographers who appreciate innovation in their gear.
Compatibility
Compatibility is another significant factor when choosing between these two lenses. The OM SYSTEM lens is designed for Micro Four Thirds cameras, making it an excellent choice for users within that ecosystem. On the other hand, the TTARTISAN AF 27mm lens is compatible with various Fuji X mount cameras, including popular models like the Fujifilm X-S10 and X-T4. Therefore, the lens choice largely depends on which camera system the photographer is using, as neither lens will perform optimally outside its intended system.
Which should you buy?
In conclusion, the choice between the OM SYSTEM Olympus M.Zuiko Digital 40-150mm and the TTARTISAN AF 27mm f2.8 largely depends on the photographer's needs and preferences. If you prioritize versatility and a wider focal range, the OM SYSTEM lens would be the better option, despite its higher price. However, if portability, low-light performance, and innovative features are more important, the TTARTISAN presents a compelling case with its lower cost and compact design. Ultimately, consider your specific photography style and equipment compatibility when making your decision.
