OM SYSTEM Olympus M.Zuiko Digital 40-TTARTISAN

Overview

The OM SYSTEM Olympus M.Zuiko Digital 40-150mm F4.0-5.6 R and the TTARTISAN 40mm f2 Lens for Z Mount cater to different photography needs and styles. The Olympus lens is a versatile zoom lens suitable for Micro Four Thirds cameras, while the TTARTISAN lens is a prime lens for Nikon Z-mount cameras. Both lenses offer unique features that appeal to different types of photographers.

Design and Build Quality

The TTARTISAN 40mm f2 Lens features a compact and ultra-portable design, weighing only 167g. Its construction from premium 5052 aerospace aluminum not only ensures durability but also makes it easy to carry on adventures. In contrast, the OM SYSTEM Olympus lens is designed as a 3.75x zoom lens, providing a focal length range of 40-150mm. While it may not be as lightweight as the TTARTISAN, it offers a robust build suitable for various shooting scenarios, particularly in the Micro Four Thirds system.

Focal Length and Aperture

The OM SYSTEM Olympus lens has a focal length range of 40-150mm with a maximum aperture of f/4-5.6. This zoom capability allows for flexibility in framing shots, whether capturing distant subjects or intimate portraits. On the other hand, the TTARTISAN lens has a fixed focal length of 40mm and a wider maximum aperture of f/2. This makes it particularly advantageous in low-light conditions, allowing for better depth of field and subject isolation.

Autofocus and Performance

The OM SYSTEM Olympus lens features High-Speed Imager AF (MSC), which enhances its autofocus performance. This is especially beneficial for capturing fast-moving subjects, as it delivers quick and precise focusing. Conversely, the TTARTISAN lens boasts advanced autofocus capabilities, including an STM motor and face/eye tracking. This provides smooth focus transitions, making it ideal for both portrait photography and videography. Each lens has its strengths, with the Olympus lens excelling in zoom versatility and the TTARTISAN lens shining in low-light scenarios.

Image Quality

When it comes to image quality, both lenses offer impressive results within their respective ranges. The OM SYSTEM Olympus lens delivers a maximum image magnification of 0.16x, which is suitable for a variety of photography styles, including landscapes and portraits. Meanwhile, the TTARTISAN lens is designed to provide true-to-life perspectives, with a 57° full-frame angle that mimics human-eye vision. This makes it particularly effective for capturing authentic textures and details, especially at a minimum focus distance of 0.4m.

Price Comparison

The OM SYSTEM Olympus lens is currently priced at $175.99, while the TTARTISAN lens comes in slightly cheaper at $168.00. This makes the TTARTISAN lens about 4.3% less expensive than the Olympus lens. While the price difference is relatively small, it may influence budget-conscious buyers who are considering which lens to invest in.

Compatibility and Usage

The OM SYSTEM Olympus lens is specifically designed for Micro Four Thirds cameras, making it compatible with both Olympus and Panasonic models. This specialization allows photographers using these systems to fully leverage the lens's capabilities. In contrast, the TTARTISAN lens is compatible with a wider range of Nikon Z-mount cameras, including models like the Z50, Z5, Z6, and Z7. This versatility makes the TTARTISAN lens a strong choice for Nikon users looking for a reliable prime lens.

Which should you buy?

Choosing between the OM SYSTEM Olympus M.Zuiko Digital 40-150mm F4.0-5.6 R and the TTARTISAN 40mm f2 Lens ultimately depends on your photographic needs and equipment. If you require versatility and the ability to zoom in on subjects, the Olympus lens is a solid option. However, if you prioritize a lightweight design and superior low-light performance, the TTARTISAN lens stands out. With a slight price advantage, the TTARTISAN may appeal to those looking for budget-friendly options, while the Olympus lens may be better suited for Micro Four Thirds users seeking a robust zoom capability.
