Professional nature and wildlife photographer Keenan Hursh recently put these advancements to the ultimate test, conducting a real-world, side-by-side comparison of the Canon EOS R5 and its newer iteration, the Canon EOS R5 Mark II, during a specialized wildlife photography workshop in the tiger-rich national parks of India.
The Technological Imperative in Wildlife Photography
Wildlife photography, an art form both immensely rewarding and inherently challenging, requires a confluence of planning, skill, knowledge, and often, a degree of fortune, to achieve a ‘dream shot.’ Even when all human elements align, the quality, capabilities, and performance of photographic gear remain paramount. The past decade has witnessed a staggering transformation in camera technology, particularly beneficial for capturing dynamic and often unpredictable wildlife. Mirrorless cameras have largely superseded traditional DSLRs, offering advantages such as more sophisticated electronic viewfinders (EVFs), stacked sensors that enable faster readout speeds, and advanced computational photography features. These innovations allow photographers to capture fleeting moments that were simply not realistically achievable with older equipment, pushing the boundaries of what is possible in the field.
An Expedition to India’s Wild Heart: Bandhavgarh and Kanha National Parks
Keenan Hursh, a renowned nature photographer, guide, and writer, embarked on a 10-day expedition to India, leading a photography workshop for Backcountry Journeys. The primary objective was to photograph Bengal tigers and a diverse array of other indigenous wildlife species in their natural habitats. The journey commenced in Delhi, from where the group traveled to Bandhavgarh National Park, followed by a six-hour drive south to Kanha National Park. Both parks, nestled in the state of Madhya Pradesh, are celebrated for their biodiversity and, critically, for hosting robust populations of Bengal tigers, offering unparalleled opportunities for wildlife enthusiasts and photographers.
Bandhavgarh, known for its dramatic cliffs, ancient fort, and high tiger density, provides a unique backdrop for photography. Kanha, on the other hand, presents a more expansive landscape of grasslands and sal forests, often described as the inspiration for Rudyard Kipling’s "The Jungle Book." The varying terrains and ecosystems in each park presented diverse photographic challenges and opportunities, making them ideal testing grounds for high-performance cameras.
Over the course of the workshop, the group recorded an impressive 15 individual tiger sightings, exceeding initial expectations and providing numerous close encounters.

Despite its groundbreaking features, the R5 presented a few minor operational quirks for wildlife photographers. The default method for switching between photo and video modes was often described as cumbersome, potentially causing missed opportunities in fast-evolving wildlife scenarios. Furthermore, when utilizing the electronic shutter, the lack of auditory feedback and the presence of momentary blackouts in the electronic viewfinder could disrupt the continuous tracking experience. While the AF was generally highly effective, occasional instances of erratic behavior or difficulty in consistently identifying subjects were noted by some users. These were minor points, however, against a backdrop of overwhelmingly positive performance that cemented the R5’s status as a professional-grade tool.
Canon EOS R5 Mark II: Iterative Advancements for Demanding Environments
Introduced as the successor to the highly acclaimed R5, the Canon EOS R5 Mark II aimed to refine and enhance the core capabilities, specifically targeting the needs of action and wildlife photographers. While maintaining the same 45-megapixel resolution and many of the R5’s beloved features, the Mark II introduced several critical upgrades:
- Enhanced Autofocus: The R5 Mark II features a next-generation autofocus system, significantly improving speed, accuracy, and reliability. This enhanced AF is less prone to "jumping" between subjects and maintains a stronger lock on the intended target, even in complex, fast-moving scenarios. The ability to seamlessly switch between multiple identified subjects further refines the user experience.
- Stacked Sensor Technology: A pivotal upgrade is the inclusion of a new stacked CMOS sensor. While the resolution remains consistent, this sensor architecture dramatically improves data readout speeds. This translates directly to:
