Introduction

When considering a lens for birding, the Olympus 40-150mm f2.8 Pro is a popular choice among bird enthusiasts. However, its effectiveness can depend on your specific needs and the type of birding you intend to do. In this article, we explore the suitability of the Olympus 40-150mm f2.8 Pro for birding, compare it with other popular options, and discuss alternative choices for both short and long-range birding.

Benefits and Limitations

The Olympus 40-150mm f2.8 Pro offers a versatile focal range, making it suitable for a wide range of bird species. The constant f2.8 aperture allows for excellent low-light performance and shallow depth of field control. However, it might not be the ideal choice for distant shots, particularly when dealing with wild birds that are often at substantial distances.

Many bird photographers opt for lenses in the 300mm to 500mm range, such as the Olympus 150–400mm f/5–f/6.3 or the Panasonic Leica 100–400mm f/4–f/6.3, which can provide better reach for wild bird photography. These lenses are more commonly found in the groups of photographers on Facebook, especially those in the Olympus OM-D community. Additionally, using 1.4x teleconverters with the 40-150mm can extend its reach, but they are also used with the 300mm f4 lens to achieve even greater focal lengths.

Micro Four Thirds and Crop Factor

The Olympus micro four-thirds system has a crop factor that effectively doubles the focal length when compared to a full-frame camera. Therefore, a 40-150mm lens on a micro four-thirds camera has the equivalent of 80-300mm on a full-frame sensor, which is still relatively short for long-range birding. This factor is crucial to consider as it can limit the capabilities of the lens in certain birding scenarios.

For example, if you are birding in a zoo, the 40-150mm might suffice, as the distances between the bird and the observer are typically shorter. However, for wild bird photography, where you may be hundreds of meters away, a longer lens is more practical. Experienced bird photographers often recommend lenses like the EF 100-400L II for wild birding, as they offer the necessary reach and image quality.

Conclusion and Recommendations

While the Olympus 40-150mm f2.8 Pro is a versatile and capable lens, it might not be the best choice for long-range birding. The Olympus 150-400mm f5-6.3 or the Panasonic Leica 100-400mm f4-6.3 can provide better reach and low-light performance. For those looking for even greater focal lengths, consider using 1.4x teleconverters with the 40-150mm or opting for longer lenses like the EF 100-400L II.

Ultimately, the choice of lens depends on your specific birding needs, such as the environment and the types of birds you plan to photograph. Understanding the limitations and benefits of different lenses can help you make an informed decision that enhances your birding experience.
