Seeking The Best Lens For Bird Photography: FUJINON GF 500mm f5.6

Birding with a medium format camera might initially sound like an unconventional pairing, but Fujifilm’s FUJINON GF 500mm f5.6 lens challenges the status quo. As a photographer, I approached this lens with a mix of excitement and skepticism, unsure if it could truly deliver on its promises. However, after reading numerous reviews and experiencing the FUJINON GF 500mm f5.6 firsthand, I’ve formed a well-rounded opinion on this intriguing lens. I’m pleased to say that the GF 500mm f5.6 exceeded my expectations in many ways.

First Impressions

Weighing just 1375g (3.03 lbs) and measuring 24.7 cm (9.4 inches), it’s remarkably portable for its class. Fujifilm has clearly focused on making this lens a practical option for photographers who need to carry their gear for extended periods.

Build Quality and Design

The lens boasts weather resistance, a crucial feature for outdoor photography, particularly in environments where conditions can be unpredictable. During my testing, I appreciated the lens’s durability, knowing that it could withstand the rigors of birding expeditions in various climates. Extending your creative vision, the FUJINON GF500mm F5.6 R LM OIS WR lens offers a focal length equivalent to 396mm. This compact, lightweight, and weather-resistant lens delivers detail-rich results up to 102 megapixels, featuring fast, silent autofocus with focus preset controls, and a 6.0 stop Optical Image Stabilizer to combat camera shake.

In terms of design, the GF 500mm f5.6 shares similarities with Sigma lenses, prompting speculation about its origins. However, Fujifilm asserts that it’s an original OEM creation, with unique optical formulas and designs. Some may question its resemblance to Sigma lenses, but the GF 500mm f5.6 is well crafted and ergonomic, with intuitive controls that facilitate smooth operation in the field. Measuring 24.7cm (9.4in) and weighing just 1375g (3.03lb), it remains portable and, importantly, highly maneuverable in crucial moments, making it the ultimate field companion for wildlife photography and bird photography.

Autofocus Performance

One of the lens’s notable drawbacks is its autofocus speed, which falls short of the performance offered by DSLR counterparts. While it’s adequate for most situations, capturing fast-moving subjects like birds in flight can be challenging. Fujifilm’s autofocus system, while functional, lacks the refinement and speed of industry-leading systems from Canon, Nikon, and Sony. However, the silent, high-speed autofocusing, along with focus preset options, ensures that no moment is missed, which is essential for framing distant sport and wildlife subjects to perfection.

During the tests, the Fujifilm GFX 100S was primarily used in AF-C mode with tracking. It yielded satisfactory results but occasionally struggled to keep pace with erratic bird movements. Switching to Boost Mode provided a slight improvement in autofocus speed but didn’t entirely eliminate missed shots. Overall, patience and skill are essential when using the GF 500mm f5.6, particularly in demanding wildlife photography scenarios.

Image Quality

Where the FUJINON GF 500mm f5.6 truly shines is in its image quality. Despite its autofocus limitations, the lens delivers stunningly sharp images with excellent color rendition. Various film simulations, including Velvia and Classic Chrome, offer distinct visual characteristics that add depth and personality to the photos. Fujifilm built the GFX System digital camera products to provide astounding image quality, and the FUJINON GF500mmF5.6 R LM OIS WR lens is an optic to match. Each of the lens’s elements delivers maximal resolving power equipped to meet that of a 102-megapixel sensor.

The lens’s ability to capture both clinical sharpness and subtle character is commendable, making it a versatile tool for photographers seeking creative expression. Whether shooting landscapes or wildlife, the GF 500mm f5.6 consistently produces captivating images that exceed expectations.

Extended Reach

While this lens offers incredible coverage as standard, there’s potential to go further. Greater telephoto power can be achieved by adding the optional FUJINON GF1.4X TC WR teleconverter (sold separately), resulting in a 35mm equivalent focal length of 554mm. This extension makes it even more powerful for capturing distant subjects in wildlife photography and bird photography.
